Necrophagous insects, mainly Diptera and Coleoptera, are attracted to specific stages of carcass decomposition, in a process of faunistic succession. They are very important in estimating the postmortem interval, the time interval between the death and the discovery of the body. In studies done with pig carcasses exposed to natural conditions in an urban(More)
This study aimed to provide the first checklist of forensically-important dipteran species in a rainforest environment in Northeastern Brazil, a region exposed to high rates of homicides. Using a decomposing pig, Sus scrofa L. (Artiodactyla: Suidae), carcass as a model, adult flies were collected immediately after death and in the early stages of carcass(More)
Entomotoxicology is focused on obtaining data on necrophagous entomofauna, for criminal investigations purposes. This study aimed to evaluate the effect of different concentrations of methylphenidate hydrochloride, phenobarbital, and their association on the developmental rate, larval and pupal survivorship, and the interval of emergence of adults of(More)
Necrophagous insects are valuable tools for postmortem interval (PMI) estimation or for determining the cause of death. Due to the increase in deaths related to drug abuse, it is crucial to know how these substances affect the development of flies that feed on corpses, to avoid errors in the PMI estimates. This study evaluated the effect of nandrolone(More)
Since insect species are poikilothermic organisms, they generally exhibit different growth patterns depending on the temperature at which they develop. This factor is important in forensic entomology, especially for estimating postmortem interval (PMI) when it is based on the developmental time of the insects reared in decomposing bodies. This study aimed(More)
Cases of myiasis in man associated with preexisting lesions are quite common. However, in the forensic field, certain behavioral habits related to insects may be useful to ratify mistreatment. This is a register of a case of oral myiasis by Cochliomyia hominivorax (Diptera: Calliphoridae), an obligate parasite of warm-blooded animals, in a 95-year-old man(More)
Blowflies have major medical and sanitary importance because they can be vectors of viruses, bacteria, and helminths and are also causative agents of myiasis. Also, these flies, especially those belonging to the genus Chrysomya, are among the first insects to arrive at carcasses and are therefore valuable in providing data for the estimation of the minimum(More)
The use of heterogeneous animal tissues for the rearing of necrophagous insect species can produce uneven biological data, which can compromise the determination of larval age and, consequently, estimates for post-mortem intervals. We investigated the development of two species, Chrysomya megacephala and Chrysomya putoria (Diptera: Calliphoridae), reared on(More)
Larval therapy (LT) is the application of carrion flies (Diptera) sterile larvae on chronic or infected wounds to promote or accelerate the healing process. High cost and the development of resistance by certain groups of pathogenic bacteria to these drugs encouraged the resurgence of LT, currently used in approximately 20 countries and more recently in(More)
