Materials and methods: On 15 British farms, invertebrate communities were trapcollected (14 per year), counted, and sorted into species groups. Lawsonia serological tests were conducted and total DNA was extracted from pig feces; DNA was also extracted from adult flies, pupae, and larvae samples and viscera of Blatta species. Each DNA sample was tested for L intracellularis by polymerase chain ...

Adult specimens of Cochliomyia macellaria, Chrysomya megacephala, Ch. rufifacies, Lucilia sp. (Calliphoridae), Musca domestica (Muscidae), Oxelytrum discicolle (Silphidae) and Sarcophagidae were recovered from 12 human cadavers in Cali, Valle, Colombia. Information regarding these findings is presented.

In the housefly Musca domestica, synthesis of yolk proteins (YPs) depends on the level of circulating ecdysteroid hormones. In female houseflies, the ecdysterone concentration in the hemolymph oscillates and, at high levels, is followed by expression of YP. In male houseflies, the ecdysterone titre is constantly low and no YP is produced. In some strains, which are mutant in key components of t...

Drosophila and Musca both belong to the group of higher dipteran flies and show morphologically a very similar early development. However, these two species are evolutionary separated by at least 100 million years. This presents the opportunity for a comparative analysis of segmentation gene expression across a large evolutionary distance in a very similar embryonic background. We have analysed...

Any deviation in ambient temperature causes stress and disturbs the cellular homeostasis in the organisms. In the present study, genotoxicity induced by exposure of high temperature (40o, 45o and 50oC) has been analyzed in the third instar larvae of common housefly, Musca domestica, by using chromosome aberration assay, micronucleus assay and mitotic index as cytological end points. The adverse...

A diet for rearing the house fly, Musca domestica (L.), was developed from feed constituents available on a year-round basis in Gainesville, FL. The diet, called the Gainesville House Fly Diet, performed as well or better than the Chemical Specialties Manufacturers' Association fly larval medium (CSMA) and can be mixed, bagged, and delivered by a local feed mill within 3 d. By adding pelleted p...

The tiny, spiny-legged rove beetle, Anotylus latiusculus (Kraatz) ernerged from house fiy puparium collected from a vegetable farm in the Carneron Highlands, Pahang. This beetle parasitoid, and microhymenepteran Spalangia are natural enemies of fiies. Spalangia spp. play important roles in regulating the fiy population in Malaysia. However, this role is doubtful for the spinylegged rove beetle ...

The ultrastructural superficial changes in third instar house fly (Musca domestica) and blow fly (Chrysomya megacephala) induced by eucalyptol oil were observed using scanning electron microscopy. Dipped in 0.902 g/ml eucalyptol for 30 sec, the larvae integument of both species showed significant aberrant appearance of the body surface, particularly swelling integument, bleb formation, partial ...
