| Abstract | |
The estimation of the postmortem interval (PMI), period between the occurrence of death and the time at which the body or casing is found, is one of the main uses of insects in the forensic field. Using information on the biology, ecology and geographical distribution of insects, as well as the behavior of the entire fauna present in a body, is possible to estimate the time of death. Several factors such as temperature, humidity, presence of toxic substances in the tissues of a carcass, may interfere with the life cycle of an insect, directly affecting the estimate of PMI when it is based on biological parameters of the insect. Therefore, multiple factors should be considered so that the forensic analysis is more accurate. With the increase in the number of animal's deaths of economic importance due to drug intoxication, becomes necessary a research on entomotoxicology, an area with lack of specific studies. Thus, the present study aimed to identify the insect fauna associated with carcasses of goats (Capra aegagrus hircus L.) killed after treatment with ivermectin and exposed in the natural environment. Still, investigate possible differences in attractiveness, the immature development that used this substrate for feeding and if the temperature and the colonization pattern of larval mass differ between carcasses of animals killed after ivermectin inoculation. This last parameter was evaluated by thermographic shots performed at intervals of 12 hours. Besides the importance of abiotic factors such as luminosity, temperature, humidity and rainfall, the action of ivermectin on carcasses couse interferense in the composition of the colonizing fauna, the total time of colonization and the time of the decomposition stages, as well as the physical patterns and behavior of larval masses compared to the control group. Although it has been shown that thermography can be used as a new tool in forensic studies, helping to evaluate the parameters of larval mass (AU) | |
