Abstract
This study was carried out to identify malathion which may cause the death. Toxicological analysis was applied to the forensically – important blow fly larvae C. albiceps which is the most abundant fly attracted firstly and consume the flesh of carcass as their food substrate. In addition to detection of malathion in tissues of blow fly larvae fed on treated – dog carcasses using gas chromatography with flam ionization detector (GCFID.), the effect of this chemical compound on insect succession, frequency of insects attracted to dog carcass and the development rate of C. albiceps larvae as the most important consumer of carcass tissues and can affect the estimate of postmortem interval (PMI) were investigated.
Highlights
Entomotoxicology is a new area of criminal investigation, where entomological evidence is analyzed to determine whether or not drugs or toxins were used prior to death
Entomotoxicology includes the study of the effects of drugs, toxins and opiates on the development rate of carrion-feeding insects (Goff and Lord 2001), and the use of these as alternative sample in the absence of other tissues
As shown from the results, the number of adult fly was 184 and 142 for treated and control dog carcasses, respectively (Tables 1, 2). In both dog carcasses (Malathion – dead dog and control dog), the insect succession firstly attracted to both carcasses were dipterous flies which were represented by the following insects; C. albiceps, (Calliphoridae), Musca domestica (Muscidae), Sarcophaga carnaria and Wolhfartia magnifica (Sarcophagidae), and Piophila casei (Piophilidae)
Summary
Entomotoxicology is a new area of criminal investigation, where entomological evidence is analyzed to determine whether or not drugs or toxins were used prior to death. Necrophagous insects may provide useful information about the time, place, and cause of death. In addition they can serve as reliable alternative specimens for toxicological analysis in cases where human tissue and fluid, normally taken during autopsies, are not available due to composition of the corpse. The true flies of families; calliphoridae (blow flies), sarcophigidae (flesh flies), and muscidae (houseflies) are highly motile, strong- flying insects and are typically the first to reach the dead body, often within minutes of death (Smith, 1986; Goff, 1993; Kabadaia, 2015). Entomotoxicology includes the study of the effects of drugs, toxins and opiates on the development rate of carrion-feeding insects (Goff and Lord 2001), and the use of these as alternative sample in the absence of other tissues. Especially C. albiceps play a fundamental role in the carcass decomposition (Kabadaia, 2015)
