Four different thrips species; marigold thrips, Neohydatothrips samayunkur; western flower thrips,
Frankliniella occidentalis; tomato thrips, Frankliniella schultzei and onion thrips, Thrips tabaci were
recorded on marigold plants in the field. Tagetes erecta L. was grown on the experimental farm,
Giza governorate, Egypt. The survey was carried out during mid–April to late
July and from early September to late December 2013. Weekly samples were randomly selected and
examined for the presence of the different thrips species. Identification of thrips species was based
on morphological characters. Neohydatothrips samayunkur recorded the highest average numbers in
both periods of the survey, from mid–April to late July and from early September to late December
2013 (189.5 and 143.6 individuals/plant, respectively), while the lowest number was recorded for T.
tabaci (4.6 and 5.9 individuals/plant). This is the first report of N. samayunkur in Egypt. Description
of the recorded species is given as well as their seasonal abundance on marigold plants.

University Forensic Misconduct: Pamela A Fish Forensic science is defined as the practice of
utilizing scientific methodologies to clarify judicial inquiries. The field of forensic science contains
a broad range of disciplines and has become a vital aspect of criminal investigations. Some forensic
disciplines are laboratory–based; while others are based on an analyst's interpretation of observable
patterns (Kourtsounis, 2009). According to the Innocence project's website; in greater than fifty
percent of wrongful convictions, the use of invalidated or improper forensic techniques played a role

another man name Dennis McGruder had been arrested and charged with those crimes the
prosecution still moved forward with Willis' case (Warden). The only piece of physical evidence in
this case was a scrap of toilet paper; which, contained traces of semen on it. (In 1992, after two
separate jury trials Willis was convicted based on identification of eyewitness identifications, as well
as the rape victims. He was sentenced to one hundred years in prison. The prosecution in this case
failed to disclose to the defense attorneys that they had received a report; which, stated that one of
the rape suspects had type A blood. This was exculpatory evidence as Willis had type B blood. Dr.
Fish's hand written lab notes concluded that the secretor of the semen had type A blood; however in
her official report and later her testimony, she falsely testified that she was unable to complete the
test because the biological sample was too small to test. In 1997, under a new law granting him the
right to seek DNA testing, Willis filed a petition. Prosecutors claimed that the biological evidence
had been lost, but was later found. The DNA sample was tested and found to exclude Willis as the
donor. After eight years of incarceration, another man Dennis McGruder confessed to the crimes
after being linked via DNA. Willis (Fisher, 2014) was released from custody

Do mothballs or ammonia help in repelling squirrels? Moth balls and ammonia are one of the most
common repellents that people use to get rid of nasty squirrels, but, unfortunately, they are not very
useful. There are several ways how to use these repellents and hope for the best results, although it
usually won't fix your problem with the rodents. Ammonia drives the squirrels mad because of their
developed sense of smell and can scared them away for some time. Also, it reminds them to the
urine of the predators and natural enemies. All you have to do is to wet some rags with ammonia and

Missouri Valley College
Abstract
Forensic entomology is an important part of forensic science. Forensic Entomology: Arthropods and
Legal Investigations.
Forensic science is the past, present and future of justice systems around the world. It has made the
jobs of those in the justice system less challenging and made the lives of criminals less bearable.
One of the many disciplines of forensic science is forensic entomology which is the study and use of
arthropods to help in legal investigations. Forensic entomology has been around since the medieval
times and it has grown from then to sub disciplines of forensic entomology with the medicolegal sub
discipline being the most employed in criminal cases. The science behind forensic entomology is the
integration of other areas of science, which are the decomposition timeline of bodies, the life cycle
of insects and the types of insects that will invade that body and the knowledge of how to collect
and rear them will help estimate the time between death and discovery, called the Post Mortem
Interval, and with the help of other disciplinarians of forensic science, all the information gathered
could be used by an expert witness to testify in a trial and help to reach a verdict.
With the growing interest and recognition of forensic entomology nowadays, the discovery of this
form of forensics can be credited to a number of scientists

The Casey Anthony Case revolves around a child named Caylee Anthony who was allegedly killed
by her mother Casey Anthony. As the trial progressed it is shown that although Casey presented
multiple lies she was still proven not guilty. Despite Casey Anthony's Parents statements, or the
graphic opening statements made by both the prosecution and defense: defense won this trial. They
proved the prosecution's evidence to be circumstantial when it came to the conviction of Casey
Anthony. With the help of forensic entomology, forensic scientists were able to find the remains of
Caylee Anthony, and fill one of the many holes protruding into this case. By using forensic
entomology and knowledge about the lifespan of insects, forensic scientists were able to figure out
just how long Caylee has been deceased after her disappearance.
On June 16th, 2008, Caylee Anthony– daughter of Casey Anthony – was the final day she was seen

On December 11, 2008 skeletal remains of a young child were found by an utility worker. By the
time the worker had discovered the remains it had went through 5 stages of decomposition. The 1st
stage starts when the person dies (Csanyi). The 1st stage consists of enzymes in dead body cells start
breaking down tissues which is known as autolysis. While this is going on bacteria in the digestive
track start to eat the intestines. The 1st stage is called the fresh stage which can last for 1–2 days,
unless of course the body is in a hot and humid area (Csanyi). Also at this stage chemical released
start to attract flies. The 2nd stage that the body went through is called the putrefaction or the
bloated stage (Csanyi). As the internal bacteria form the intestines start to enter the rest of the body,
it causes the body to fill with gasses and as this happens the body begins to swell. The smell that
comes from this stage is what attracts egg laying insects most of which are blow flies (Csanyi). The
3rd stage of decomposition that the body went through while at the dump site is what is known as
the purging or decay stage (Csanyi). During this stage of the process fluids form inside the body
start too come out of the body through the nose or mouth or through breaks in the abdominal wall
and through any soft tissue as the decomposition progresses (Csanyi). Larval ... Show more content

A crime scene is not necessarily the location of a crime, it can be where the planning took place,
where the body is found and where the evidence is found. The crime scene can be as small as a bite

First of all, the crime scene has to be cordoned off from the public, this consists of two types of
cordoning; inner and outer. Inner cordoning is where the main forensic examination takes place
whereas the outer cordoning is used to prevent the public from entering. Cordoning is important as it
keeps the public out of the crime scene, so that evidence cannot get tampered with or contaminated,
tents are also put over crime scenes which are outside to avoid people and press looking in on the
crime scene and protect evidence from the weather elements and animals which may accidently
tamper with evidence. Without cordoning the forensic officers wouldn't have any privacy from the
public which could interfere and contaminate evidence. Once the crime scene is cordoned off, a
common approach path is established, whereby 'stepping stones' are placed to prevent cross
contamination. This is important to establish a common approach path because without one
evidence could become contaminated or destroyed for example if a forensic officer accidently stood
on a footprint or a patch of blood, therefore spreading the blood around the crime scene, making it
harder for a hypothesis to be established.
The forensic investigators wear protective clothing and shoe covers to prevent cross contamination,
they also have their own DNA on the data base to eliminate their DNA from the suspects if it did get

Entomology: The Study of Insects and their Relatives
Insects and their terrestrial relatives belong to the phylum called Arthropoda and have inhabited the
earth for an extensive time. Paleontologists show that the earliest fossils, most primitive forms of
arthropods date back to the Devonian Period over 350 million years ago (Henning 1981). By the
Age of Dinosaurs, 300 million years ago, insects were abundant in number and diversity. Like the
dinosaurs, some pre–historic forms of insects were enormous: the dragonfly Meganeuropsis had a
wing span of 35 inches, and the giant Mesozoic relatives of the scorpions, the eurypterids, measured
over 6 feet in length (Borror and others 1992).

Grasshoppers are mostly eaten in the Oriental countries. The "guasanos de Maguey" larvae of the
giant skippers collected from the fleshy leaves of maguey plants eaten in Mexico (Borror and others

gourmet shops. In Western society insect as a food source is ostracized however some including,
honey, which is regurgitated by bees, and relatives of insects, such as lobsters, grayfish, shrimp, and
crabs, are considered delicacies. Our society has considered eating bugs, "strictly for the birds." In
fact, presence of bugs in our food source is considered contamination and unsanitary. Although
some bugs are highly lethal, not all should be cause for alarm when found on your plate– consider
them as a source of extra protein and essential lipids (Gorham 1976).
For centuries insects or their products have played a role in therapy. For instance, the jaws of soldier
ants have been as sutures for skin wounds, bee venom has been used as treatment for arthritis, and
cantharidin product from blister beetles has been used in the treatment of certain urogenital
conditions. Since the Roman Empire, it has been known that soldiers with maggot–infested wounds

46. The Science Of Entomology
Entomology is an area of forensics that studies insects. The science is mainly applied to murders,
since insects are often the first at the crime scene (Discovery Network, 2015). The bugs can be used
to analyze a body, especially to determine when and where the murder occurred (Environmental
Science, 2017). Entomologists are able to do so by analyzing the age and species of a bug
(Discovery Network, 2015). While this does not always provide necessary evidence, it often gives
police a lead in a case (Discovery Network, 2015). Ultimately, entomology is a science that works
due to biology, can serve as strong evidence, and has multiple requirements in order to go into the
field. In order to be an entomologist, one must meet multiple requirements. ... Show more content on

Entomologists are people who have worked very hard to meet all the requirements for the job
(Study, 2017). They have gone through years of college, and developed the right aptitude as well
(Study, 2017). The insects the entomologists study give multiple clues with their actions (Crime
Museum, 2017). By simply living out their life, the bugs can provide entomologists with the time a
murder occurred (Crime Museum, 2017). This can then be used to put together a report against
someone, and from there, hopefully accuse the correct person (Discovery Network, 2015).

body starts with the action of microorganisms such as fungi and bacteria, followed by the action of a
series of insects (arthropods). Bodies decompose slowly or fast depending on weather conditions, if

What are some of the challenges in determining the time of death using insects?
Ans. Some of the challenges in determining the time of death using insects would be keeping the
body in a cold environment which would completely stop decomposition. Another challenge would
be burning the body in a flammable liquid that would damage the body.
2. Why is entomology an important area of forensic science? How can this area help criminal

3. What is the process of collecting insect samples? What challenges are there in collecting samples
of insects from human remains?
Ans. First of all, forensic entomologists get the temperature of the body, and then look for the
presence of maggot mass. They also count in the weather outside the body. The body getting enough

The third type includes omnivorous insects also including specific types of ants, wasps, and some
beetles. They feed on the other insects as well as the body. Wasps will eat other adult flies, and also
feed on the fluids from the body. By eating the adult flies it can disrupt decaying for up to a day. The
last species are hunting spiders. They make webs in and around the body to catch insects. The body
provides an ideal habitat for the spiders to catch their prey. Although these are the insects that use
the body as a source of food they are not the only insects that gain food from the body. There are
also soil–dwellers that obtain food from the fluids from the body that seep into the ground. They are
usually mites, springtails, roundworms, and nematodes. The fluids that seep into the soil usually stay
there for several years after the death.
By determining what insects are on the body, and what stage of development they are in can help
determine postmortem intervals, especially in the cases of flies. There are a few factors that do play
into delaying or speeding up the decaying process with insects. A few aspects that will delay insect
activity are burying a body which also delays decomposition, covering the corpse especially tightly,
being in the water, cold weather, and the height of the body from the ground, for example in a
hanging. Only insects that can fly can reach the body, so it delays activity, but insects do feed off of

86. Advantages Of Electric Fly Killers
How effective are electric fly killers in killing flying insects?
Nowadays, there are always flying insects that are wandering around in a certain place and people
seem to be having a very hard time catching them and killing them at the same time. These flies are
a nuisance to every person because nobody would want to have flies in the house. People would find
these flying insects flying around mostly in their homes, however, they cannot seem to find the
source of this problem. This has occurred every year and yet, people could not find the source of
these problems. Some factors that could be affecting this problem is the change in weather of every
month or season, things that are dirty that may attract flies, etc. The magnitude of this problem may
increase if a solution is not implemented to solve this problem as soon as possible.
Application/Solution
There are different kinds of applications or solutions to this issue, ... Show more content on

The first one is that obviously, electric fly killers eliminate lots of flying insects right away, and it
greatly reduces the insect population around the area. There might be piles and piles of insects
within a few days, and while eventually there will be lesser insects, there is no denying that electric
fly killers play a huge impact on solving this issue. The second benefit is that similarly, electric fly
killers allow people to eliminate flying insects with few chemicals and not much personal
involvement. There is no health risk when it does not come to handling the electric fly killers, nor
there any risk of disturbing or a nest or facing an insect that people fear. Electric fly killers are out of
the way and it has limited personal involvement, so people would not need to involve in anything
when it comes to using electric fly killers. For many people, this is enough to make these devices a
popular choice for people that think of flies as a nuisance to

Abstract:
People want to avoid insects being attracted to lights at parties, so some people take to buying
yellow insect repellent bulbs. A yellow bulb as an insect repellent bulb is strange because insects are
capable of seeing the color yellow and some insects are even attracted to yellow. What consumers
need to know is if yellow light bulbs repel insect. This lab's objective was to determine if nocturnal
insects are repelled by yellow lights and how that repulsion compares to red, soft white, or a black
light. The most important materials needed in this experiment were a lamp, a variety of light bulbs,

Insects may not be as active during overcast conditions. Only two beetles were captured during the
duration of this experiment because local beetles may not have been within range of the light source
and it is still too early in the spring for an excess of beetles. This study needs to be improved by
extending the number of nights each light is utilized and by testing the different light colors at
different seasons of the year.

94. Crime Scene Investigation Essay
At a crime scene, insects can provide important pieces of information to criminal investigators,
including estimating the post–mortem interval (PMI) and determining where the crime took place.
This is only possible, however, if the local insect fauna is known, thereby facilitating the need for
local insect population surveys at both the morphological and gene levels. Although flies (order
Diptera) are one of the first and most prevalent necrophagic insect species found associated with a
corpse, beetles (order Coleoptera) are also a forensically relevant insect that can play a significant
role in crime scene investigations.
In this study, the objective was to survey the Coleoptera population in Lyon County, Kansas during
the early spring. Insects were collected using light traps during the evening hours and DNA was
isolated from each collected specimen followed by amplification of the cytochrome oxidase I (COI)
gene. The cytochrome oxidase I (COI) gene is known to be as a standard barcode gene. (CBOL,

Three representative organisms: Arthropods Coleoptera (beetle) The Coleoptera (beetle) is
characterized by "hardened front wings (elytra)" that "meet in a straight line down the center of the
back" ("Coleoptera," General Entomology, 2012). The complete development cycle of beetles
consists of the conventional egg, larva, pupa, and adult progression. The class is "divided into four
suborders. The most common are Aedephaga and Polyphaga. In the case of Aedephaga, "the first
abdominal sternum is divided by the hind coxae" and in the case of Polyphaga "the first abdominal
sternum is undivided" ("Coleoptera," General Entomology, 2012). Beetles come in a wide variety of
types. "Coleoptera is the largest order in the animal kingdom. It includes 40% of all insects and
nearly 30% of all animal species" ("Bug Bytes," General Entomology, 2012). Beetles can exist as
"predators, parasites or commensals" in terms of the way in which they survive and sustain
themselves ("Bug Bytes," General Entomology, 2012). Lepidoptera (Arctiidae) The class of
Lepidoptera (moths and butterflies) is the second largest order in the insect world. Nearly all
organisms begin the form of larvae called caterpillars (Meyer 2009). After undergoing a pupae

The field of forensic anthropology centers on the analysis of human remains; a key component of
such an analysis is the knowledge of how much time has passed between the death of an individual
and the discovery of the associated remains. This period is termed the postmortem interval and is
useful in regards to providing an identification of remains, as awareness of the time of death can be
instrumental in determining the specifics of a crime. Determination or estimation of the postmortem
interval (PMI) is possible due to certain consistencies in the process of decomposition of organisms
as well as both biotic and abiotic factors associated with decaying remains. Over time, new methods

Following the cessation of cardiac and respiratory functions in humans, cell death commences
leading to the complete death of the individual. The chemical processes that result from the massive
death of cells, such as release of enzymes and digestive fluids, act to begin the decay of the cadaver.
Of important note, normal bacteria associated with the human digestive system are no longer held in
check by the human immune system and the physical separations between the digestive tract and the
other organs. Thus, bacterial action is a critical decay component, and the significance of such
action will be investigated shortly. In traditional forensic taphonomic nomenclature, the cadaver
progresses from the "fresh" stage upon death to the "bloat" stage at the beginning of microbial
action (Finley et al. 2015). Upon the onset of insect activity, "active decay" begins until most
consumable matter is removed, leading to the "advanced decay" stage; "dry" decay follows when
only bone and keratinous tissue remains (Finley et al. 2015). Based upon environmental conditions
such as temperature and moisture availability, the time interval for each of these stages and thus the
overall decay process from fleshed body to skeleton may vary significantly. Thus, a standard
taphonomic analysis of remains may not provide a very accurate indication of PMI; however, other
methods used in conjunction can greatly increase accuracy in PMI

110. The Murder Of The Murdered Or Suicide Victims
Rationale:
Over the years I have been consistently watching the TV show 'Bones'. In this TV show the main
protagonist is a forensic anthropologist..... Most of the TV shows I have watched over the years have
always had a forensic scientist, or forensic anthropologist. It has always been fascinating how the
forensic analysts could deduce the exact time when a person was murdered to the correct hour and
most times to the correct minute. In each of these TV shows there were three main ways on how the
protagonists determined the time of death of the murdered or suicide victims. The three ways were
rigor mortis, algor mortis, and entomology. Using these methods they had conclusive results on how
the person was murdered and when the person was murdered.
Introduction:
Forensic science is the application of science to criminal and civil laws. Forensic scientists collect,
preserve, and analyses scientific evidence during the course of an investigation. It is used in multiple
scenarios regarding criminal cases, but in the following investigation it will be used to determine the
time of death of people. There are three major methods of determining the time of death of the
deceased: Forensic Entomology, Algor Mortis, and Rigor Mortis.
Forensic entomology is used when forensic entomologists study the bugs found on the deceased to
estimate the time of death. Algor mortis is the change in body temperature following death. This is

Summarizing a Forensic Journal article: Forensic Entomology Procedures
The field of Forensic Entomology is essentially a type of scientific study of utilizing insects and
arthropods for a criminal investigation. These small creatures are very useful to forensic
professionals, because they are naturally attracted to decomposing bodies. The bugs might even lay
eggs in the corpse. By examining the insects and their maturing larval stages, modern forensic
experts can assess the postmortem indications, and detect any changes in the dead body, leading to
evidence of the likely cause of death. Forensic entomologists are very often called upon to assist
cops in crime scene investigations. Because of this, police and investigators should be mindful of
the many potential benefits that this field of forensic entomology has to offer them. It can be used as

After a few minutes, these larvae were fixed in 70% ethanol and shipped to the forensic
entomologist. From the genital area, third instar larvae of Muscina stabulans (false stable fly) and
Fannia canicularis (little house fly) were identified. From the face, maggots of Caliphora vomitoria
(bluebottle) were identified. No Lucilia or Phaenicia (greenbottle) individuals were found.
Both M. stabulans and F. canicularis adults can frequently be found in local apartments in which
they are attracted to rotten organic matter. From second instar onwards, M. stabulans larvae prey on
other larvae. F. canicularis showed a delay of initial colonization of 3–10 days post–mortem and it is
strongly attracted to both urine and feces. M. stabulans is strongly attracted to human faeces but
lesser to corpses. The conditions were compared with those reported by Nuorteva as only few
observations on the development of M. stabulans were available. Conditions were found to be quite
similar for an estimation of a post–mortem interval of between 7–21 days, most likely around 14
days that is on 27th June 2000. This quite conservative estimate was because of the fact that it was

connected with illness transmission in people and creatures, and also myiasis. Studies and research
have connected Calliphora and Lucilia to vectors of causal operators of bacterial diseases. These
hatchlings, regularly seen on decomposing bodies, feast upon remains while the grown–ups can be
necrophagous or vegetative. Amid the procedure of rot, microorganisms (e.g. Mycobacterium) may
be discharged through the body. Flies land at the scene and lay their eggs. The hatchlings start eating

situations that ultimately made Redi to conclude his experiment. Entomology 105 ! 8. What were
the results of Redi's experiment? What happened in the experiment and what was concluded? ! –
The results of Redi's experiment were that the jars of meat that were sealed with lids seemed to have
no flies, maggots nor eggs entered in the jars, but the jars of meat that were unsealed appeared to
have flies entered into the jars, hatched eggs on the meat and produced maggots that grew up to
become adult flies. Lastly, for the jars of meat that were sealed with gauze, few maggots were seen
in the meat because the flies hatched eggs on the gauze and those eggs were dropped down to the
meat. Therefore, Redi concluded that non–living objects cannot give birth to living organisms,
disproving the theory of spontaneous generation. ! 9. For years after Redi's experiment many still

155. The Evolution Of Plague Bacteria
A 20–million–year–old flea, preserved in amber, is potentially holding an ancestral strain of the
Black Death, one of the world's deadliest pandemics in human history. The infamous plague claimed
the lives of 75–200 million people before peaking in Europe during the mid–14th century.
According to researchers in a new study, now published in the Journal of Medical Entomology, the
bacteria is believed to be an ancient strain of Yersinia pestis, a bacillus that was carried by fleas on
rats. The bacteria were discovered on the proboscis of the old flea, as well as in the flea's rectum.
"Aside from physical characteristics of the fossil bacteria that are similar to plague bacteria, their
location in the rectum of the flea is known to occur in modern plague bacteria," said George Poinar,
one of the researchers, in a news release. "And in this fossil, the presence of similar bacteria in a
dried droplet on the proboscis of the flea is consistent with the method of transmission of plague
bacteria by modern fleas." ... Show more content on Helpwriting.net ...
Although scientists are not 100 percent certain of the relationship between the bacteria and Yersinia
pestis, a close examination of the find suggests that they are indeed related. The bacteria on the flea
has features that match the modern forms of the bubonic plague bacteria, which can be characterized
by their unique
