  • Use of Insect Evidence in Criminal Investigations
    Pakistan Journal of Criminology Vol. 9, Issue 4, October 2017 (1-11) Use of Insect Evidence in Criminal Investigations: Developing a Framework for Strengthening of the Justice System Farrah Zaidi Abstract Forensic entomology is the utility of arthropods/ insects in legal investigations. Insects are an important component of cadavers feeding on the nutrient rich resource provided to them by nature. In doing so they are performing the important ecological service of decomposition. Blow flies are among the first insects arriving at the body and laying their eggs. The larvae that hatch out of the eggs are necrophagous i.e. they feed on flesh. The flies pupate in soil/dirt beneath the body. The development time of flies is specific for instance 9-10 days for oriental latrine fly. This time period allows the entomologists to calculate the time of death roughly corresponding with the time of egg laying. Besides estimating the time of death, forensic entomology in some cases can also determine child neglect, drug use prior to death and identifying potential assailants. In order to strengthen our justice system training workshops in the discipline should be made mandatory for the law enforcement agencies. A frame work should be developed to gradually incorporate the discipline in the legal system. For this purpose the science should be given its due share in the curricula of institutes of higher education and collaborative efforts must be taken to educate the current and future law enforcement professionals. Key Words: Forensic entomology, blow flies, Pakistan, time of death 1. Introduction Forensic entomology describes utility of insects and other arthropods in legal matters, especially in a court of law (Catts and Goff 1992).

Med. Entomol. 47(5): 917Ð923 (2010); DOI: 10.1603/ME09206 ABSTRACT The secondary screwworm, Cochliomyia macellaria (Fabricius), was reared on either equine gluteus muscle or porcine loin muscle at 20.8ЊC, 24.3ЊC, and 28.2ЊC. C. macellaria needed Ϸ35% more time to complete development when reared at 20.8 than 28.2ЊC. Furthermore, larval growth and weight over time did not differ between larvae reared on equine versus porcine muscle. This study is the second in the United States to examine the development of C. macellaria and is the Þrst to examine development of this species on muscle tissue from different vertebrate species. These data could provide signiÞcant information regarding time of colonization, including myiasis and neglect cases involving humans and animals. Furthermore, these results in comparison with the only other data set available for this species in North America indicate a fair amount of phenotypic variability as it relates to geographic location, suggesting caution should be taken when applying these data to forensic cases outside the region where this study was conducted.

  • Solving Crimes by Using Forensic Entomology Dr
    Solving Crimes by Using Forensic Entomology Dr. Deborah Waller Associate Professor of Biology Old Dominion University The Scenario The following is a hypothetical crime that was solved using insect evidence. Although fictional, this crime represents a compilation of numerous similar forensic entomology cases tried in the legal system where insects helped identify the murderer. The Crime Scene Pamela Martin, a 55 year-old woman, was found deceased in a state of advanced decomposition on March 30th. The body was discovered by her husband John on a path leading to a mountain cabin owned by the couple. The Martins had driven up to the cabin on March 1st, and John had left Pamela there alone while he completed a job in the northeastern region of the state. The Victim Pamela Martin was a former school librarian who devoted her retirement years to reading and gardening. She took medication for a heart condition and arthritis and generally led a quiet life. Pamela was married for 30 years to John Martin, a truck driver who was often gone for months at a time on his rounds. They had no children. The Cabin The cabin was isolated with closest neighbors several kilometers away. There was no internet access and cell phone service was out of range. The couple frequently drove up there to do repairs, and John often left Pamela alone while he made his rounds throughout the state.

  • ABSTRACT CRUISE, ANGELA MARIE. Sampling and Ecological
    ABSTRACT CRUISE, ANGELA MARIE. Sampling and ecological succession of adult necrophilous insects. (Under the direction of Dr. Coby Schal and Dr. Wes Watson). Forensic entomology links the science of entomology and the judicial system, most notably in death investigations. Using entomological evidence from a crime scene and biotic and abiotic characteristics of the environment, forensic investigators make inferences about the time since death, or the postmortem interval (PMI). Understanding parameters such as geographic location and level of concealment enables the prediction of necrophilous insect succession on a decomposing body, which is essential to PMI determination. Of particular need in forensic entomology are studies examining the pre-colonization interval and mechanisms driving insect ecological succession. The characterization of ecological succession in general, and of necrophilous insects, depends on accurate documentation of temporal and spatial changes in species diversity, richness, and abundance. Pigs are the most common models used in forensic studies because human cadavers and pigs exhibit similar decomposition patterns. The 23-kg pig is the most common pig model in such studies, but some researchers have used smaller pigs because they are inexpensive and more easily obtained. Although smaller pigs have been shown to adequately represent the local species composition dynamics throughout succession, they tend to attract fewer insects than larger carcasses and are thus more difficult to sample. First, we compared the number and diversity of insects sampled by four sampling methods, two active (vacuum, sweep net) and two passive (emergence trap, sticky traps). We also compared their efficacy at different times of day. We found that no single method was able to outcompete the other methods during all decomposition days.

Blow fly (Diptera: Calliphoridae) Responses to Different Colors of Baited Traps An Honors Thesis submitted in partial fulfillment of the requirements for Honors in Department of Biology. By Oluwadamilola Oke Under the mentorship of Dr. Edward B. Mondor ABSTRACT Blow flies (Diptera: Calliphoridae) are usually the first insects to colonize human remains. By determining the time of colonization, a postmortem interval (PMI), or “time of death”, can be estimated. To develop more accurate PMI estimates, it is important for forensic entomologists to understand the cues that Blow flies use to locate vertebrate remains. The purpose of this study was to determine whether Blow flies use visual cues, in addition to olfactory cues, to locate carrion. Two colors of fly traps, clear and green, were constructed and chicken gizzard used as bait.

  • Common Green Bottle Fly Or Sheep Blow Fly Lucilia Sericata (Meigen) (Insecta: Diptera: Calliphoridae)1 Matthew Anderson and Phillip E
    EENY-502 Common Green Bottle Fly or Sheep Blow Fly Lucilia sericata (Meigen) (Insecta: Diptera: Calliphoridae)1 Matthew Anderson and Phillip E. Kaufman2 Introduction The common green bottle fly, Lucilia sericata (Meigen), formerly Phaenicia sericata, is a common visitor to carrion, feces, and garbage. Lucilia sericata is also one of the most common species in the genus (Whitworth 2006). This blow fly is a member of the family Calliphoridae, and like many of the other blow flies, L. sericata plays an important role in forensic, medical and veterinary science. In forensic sci- ence, the larvae or maggots help to determine the period of insect colonization as it relates to the time of death, aiding law enforcement in their investigations. Medical treatment using maggot therapy can help to heal infections that are otherwise incurable (Rueda et al. 2010). In the field of veterinary medicine, feeding by larval L. sericata can cause substantial losses in animals and production (Strikewise Figure 1. Common green bottle flies, Lucilia sericata (Meigen), on dog feces. 2007).
