The importance of ghouls is known in the field of forensic investigations, since they are considered indicators of time of death or portmorten interval, however, there are factors that can influence them, such as the presence of certain toxins involved in the deaths either caused or accidental. In this sense, the objective of the present investigation was to determine the effects that the pesticides aldicarb and metamidifos exert on the biological development of two of the main species of forensic interest Chrysomya albiceps and Cochliomyia macellaria that are used for the evolution of the portmorten interval in the sciences. Forensics For this, three different doses 0.5LD50, LD50 and 2xLD50 of both toxic substances were inoculated in the food of these species. Post embryonic growth curves of Chrysomya albiceps and Cochliomyia macellaria were elaborated, based on length (mm), development time, taking into account the three doses of both pesticides; the rearing of both species was an average environmental temperature of 28.5 ºC, and an average relative humidity of 58.3%., which estimated the Postmortem interval (IPM). Based on the results of the present investigation, it can be concluded that the pesticides aldicarb and methamidophos inoculated at three different doses in their food (0.5LD50, LD50 and 2xLD50), influence the development rate of the two species Cochliomyia macellaria and Chrysomya albiceps, considered forensic indicators, this will inevitably influence the establishment of the Postmorten interval.
