The effect of neem, Azadirachta indica A. Juss, on ultrastructural alteration of larvae and puparia of the blow fly, Chrysomya megacephala (Fabricius) (Diptera: Calliphoridae) and house fly, Musca domestica (Linnaeus) (Diptera: Muscidae), was investigated in the laboratory by using neem extract containing 0.24% azadirachtin A. Larvae of both species exposed to single dipping with the neem produ...

Rate of development of forensically-important Diptera in southern Brazil. Dipteran larvae were collected from rabbit (Oryctolagus cunniculus L.) carcasses during the four seasons in 2005 in the southernmost state of Rio Grande do Sul, Brazil. The larvae were fed ground beef at ambient temperatures following collection from carcasses. The development of each species under these conditions was es...

Chrysomya megacephala (F) is a blow fly species of medical importance, being pestiferous and a mechanical carrier of various microorganisms to human food. Various strategies to reduce the fly population in endemic areas are needed. We investigated the effects of microwaves at 2,450 MHz, with third-instar exposure times of 7, 10, 15, 30 and 60 seconds on the larvae. Survival of the larvae was mo...

In this study we investigated the population dynamics of Chrysomya albiceps (Wiedemann) with laboratory experiments, employing survival analysis and stage structure mathematical models, emphasizing survival among life stages. The study also assessed the theoretical influence of density dependence and cannibalism during immature stages, on the population dynamics of the species. The survival cur...
