The succession of insect communities on carrion varies at local and global spatial scales. As such, ecological succession data obtained from corpses at one geographic location cannot necessarily be applied to other locations. Our study describes this succession in the far southern part of China to provide such data for forensic cases in this region. A total of 18 pig carcasses were placed in th...

preliminary study on insects associated with pig carcasses was conducted in Phitsanulok, northern Thailand. Five decomposition stages of pig carcasses were categorized: fresh (0-1 day after death), bloated (2 days after death), active (3 days after death), advanced (4- 6 days after death) and dry (7-30 days after death). The arthropod species collected from the corpses in the field sites were m...

During 2004, four experiments were carried out, one each season, in order to determine the species composition and seasonal dynamics of Calliphoridae in a rural area of Córdoba (Argentina). Two pigs (Sus scrofa L.), weighing approximately 8 Kg each, were used in each experiment. They were killed with a blow to the head and immediately placed in a variant of the Schoenly et al. (1991) trap. One ...

Myiases are infestations with dipteran larvae in both necrosed and living tissues, the food source of these insects. These illnesses occur in warm humid climates, and are most frequent in developing countries. We assessed the epidemiological aspects and the influence of climate on the occurrence of myiases and the bioagents in patients admitted to the federal Hospital do Andaraí in Rio de Janei...

Intra-puparial development of the females of Chrysomya albiceps (Wiedemann) (Diptera, Calliphoridae). The chronology and morphological changes that take place during intra-puparial development of Chrysomya albiceps is described based on 254 specimens reared in the laboratory. Larvae were obtained from the eggs laid by a single female. The pre-pupae were separated according to the reduction of l...

The genera Cochliomyia and Chrysomya contain both obligate and saprophagous flies, which allows the comparison of different feeding habits between closely related species. Among the different strategies for comparing these habits is the use of qPCR to investigate the expression levels of candidate genes involved in feeding behavior. To ensure an accurate measure of the levels of gene expression...

Different strains of Bacillus thuringiensis Berliner were proved to be a powerful biologic insecticide against larvae of several insect orders. Due to the epidemiological importance of blowfl ies of the Chrysomya Robineau-Desvoidy genus in the production of secondary cutaneous myiasis and mechanic transmission of pathogenic agents, the performance of two strains of B. thuringiensis (LFB-FIOCRUZ...

This is the first report of the hairy maggot blow fly, Chrysomya rufifacies (Macquart), in Canada since its arrival in the continental United States of America in 1982. Specimens were collected from one swine (Sus scrofa L.) carcass in fall 2004 and again from six swine carcasses at three rural sites within the Windsor/Essex County region of southwestern Ontario in fall 2005. Based upon the bio...

A year-long entomological survey was performed in 2016-2017 using carrion-baited traps (chicken, pork, squid, or beef) to assess the diversity of necrophagous flies municipality Yautepec, Morelos, Mexico. total 4,765 from 18 families were collected, more than 50 percent specimens collected (2,644) belonged Calliphoridae represented by five genera and eight species. Out these species we evaluate...

Identifying species of insects used to estimate postmortem interval (PMI) is a major subject in forensic entomology. Because forensic insect specimens are morphologically uniform and are obtained at various developmental stages, DNA markers are greatly needed. To develop new autosomal DNA markers to identify species, partial genomic sequences of the bicoid (bcd) genes, containing the homeobox a...
