“…Exposure to cocaine shortened the developmental time of the larvae enough to alter the estimated PMI by up to 24 h. Goff, Brown, et al (1991); Goff, Charbonneau, and Sullivan (1991) performed similar work exploring the effects of heroin on the same species, demonstrating that between hours 18 and 96 of larval development, the heroin-exposed groups grew more rapidly than the controls, but experienced significantly longer puparial stages. This line of research was continued using Parasarcophaga ruficornis (Diptera: Sarcophagidae) (Fabricius) and methamphetamine (Goff et al, 1992), amitriptyline (Goff et al, 1993), phencyclidine (Goff et al, 1994) and 4-methylenedioxymethamphetamine . Considering the continued prevalence of drug-involved deaths, improved understanding of the effects of various drugs and their metabolites on the development of various carrion-feeding species remains a critically understudied area of research in the United States.…”

The field of forensic entomology has grown exponentially within the last 50 years. While research in this discipline is conducted globally, the United States in particular has produced a significant amount of work relevant to forensic entomology. The Pacific region of the United States, characterized to include Hawai'i, Idaho, Oregon, Washington and the islands of American Samoa, Guam, and the Commonwealth of the Northern Mariana Islands, has produced a broad array of such studies. Works of interest include surveys of forensically important insects, studies on carrion decomposition and insect succession, studies on the developmental rate of sarcosaprophagous insects, molecular studies to detect differences between geographically distant populations of the same species, studies on the microbial makeup of carrion and carrion‐feeding insects, entomotoxicological research, decomposition communities in aquatic environments, and case reports detailing insects recovered from death investigations as well as myiasis of livestock and humans. This review will outline research that originates from each of the aforementioned regions and review the results, while identifying knowledge gaps, and providing recommended areas of improvement to further increase diversity of forensic entomology research in the Pacific region.

“…The detection and quantification of drugs or any foreign substance present in a corpse can be performed by analyzing the insects that are feeding on it (Pounder, 1991); indeed, they represent a reliable matrix for toxicology analyses and an increasing number of forensic toxicology laboratories are conducting routine analyses on entomological samples (Lei et al, 2019). Moreover, forensic entomotoxicology evaluates the effects that certain chemicals may have on the development and anatomy of insects (Bourel et al, 1999;Goff et al, 1989Goff et al, , 1992Goff et al, , 1993Goff et al, , 1994Goff et al, , 1997Gunatilake & Goff, 1989). Any xenobiotic-including heavy metals-that are present in the carrion may be transferred to the insects that feed on it and can potentially influence their behavior and development (Chophi et al, 2019).…”

Heavy metals such as lead, cadmium, zinc, copper, mercury, and others, are naturally occurring non degradable elements which can accumulate in the environment and in living organisms and can have a significant impact on their physiological functions. Studies have shown that heavy metals can also influence the development and morphology of insects. Insects are the most abundant organisms on earth and play a major role in different ecosystems. They help in the dispersion of organic matter and are an important part of different ecological processes. Forensic entomology focuses on the use of arthropods in legal investigations. Shortly after death, a corpse is quickly colonized by several insect families; blow flies (Diptera: Calliphoridae) are among the first colonizers and are therefore often used for the estimation of the time of colonization (TOC) or minimum post‐mortem interval (mPMI). Since larvae feed on the corpse, any xenobiotic present in the remains, including heavy metals, can be ingested, and accumulated by them; these substances can influence their development and, in turn, can alter the estimation of the mPMI. We analyzed the literature on studies pertaining to the detection of heavy metals in blow flies and on their variations in developmental rate, mass, length, fecundity, morphology, immune system, and mortality rate.This article is categorized under: Forensic Biology > Forensic Entomology Forensic Anthropology > Time Since Death Estimation Forensic Biology > Interpretation of Biological Evidence

“…Forensic entomotoxicology is consider a branch of the forensic entomology, which studies the potential use of arthropods with scavenger or necrophagous habits for the detection of possible toxicants in cases where usual biological matrices are unavailable for toxicological analysis. These cases can occur in highly decomposed bodies, skeletonized, mummified or burnt remains, with a lack of biological tissue [1,2]. Sarcophagidae and Coleoptera family are studied for forensic entomotoxicology, however the most important species is the blowflies from Calliphoridae family [3].…”

Forensic entomotoxicology is a relatively new science whose applications aims the detection of toxic substances through a matrix of necrophagous insects in a crime scene. In addition, it aims the investigation of the impacts of the xenobiotics on these insects, generating impacts in the measurement of the post-mortem interval (PMI). Calliphoridae larvae, the most important insect for forensic entomology, has an average amount of 25% of crude fat and 53% of crude protein, being a complex matrix that requires some sample preparation methodology before inserting the sample in some equipment to perform the chemical instrumental analysis. Sample preparation methods should be applied in order to increase the protection of analytical equipment from impurities present in the arthropod matrix, as well as increase the detectability of the test analyte by the analytical instrumentation of choice. Thus, the objective of the present work is to compile sample preparation techniques since traditional procedures until new approaches found in the scientific literature applied for entomotoxicological analysis in Calliphoridae specimens and respective analytes. It was observed the lack of a complete standardization for entomotoxicological approach, mainly for traditional extractions preparations. In this sense, microextraction-based techniques become an even greater challenge for arthropod–like matrix, especially in specimens from Calliphoridae family for xenobiotics determination. So, the development of sample preparation techniques with more sustainable approaches, such as reduced use of solvents, added to the increase of the powerfulness of analytical instrumental techniques should be encourage in order to improve the forensic entomotoxicology approach.
