Light microscopy photographs, line illustrations and scanning electron micrographs are provided for first instars of Chrysomya albiceps (Wiedemann), Chrysomya megacephala (Fabricius) and Protophormia terraenovae (Robineau-Desvoidy) (all: Diptera: Calliphoridae). The following morphological structures are documented: pseudocephalon; antennal complex;(More)
The calliphorid fly, Lucilia cuprina (Wiedemann), is known to cause serious malign myiasis in animals, whereas its sibling species Lucilia sericata (Meigen) is commonly a carrion breeder and is used in maggot debridement therapy (MDT). The current study reports an accidental involvement of L. cuprina in MDT in Alexandria, Egypt, that has proved to be safe(More)
In 1988 and 1989, seasonal field studies on exposed rabbit carcasses were conducted in Alexandria, Egypt, to describe the decomposition process and arthropod succession patterns. Four decomposition stages were recognized: fresh, bloated, decay, and dry. Carcasses in summer and spring decayed at a much faster rate than those in fall and winter. The bloated(More)
OBJECTIVE To assess the clinical and microbiological efficacy of maggot debridement therapy (MDT) in the management of diabetic foot ulcers unresponsive to conventional treatment and surgical intervention. METHOD Consecutive diabetic patients with foot wounds presenting at the vascular surgery unit and the diabetic foot unit of Alexandria Main University(More)
The introduction of 4 Chrysomya Robineau-Desvoidy spp. to the Americas has made obsolete previously published keys to Nearctic calliphorid larvae, particularly those covering the subfamily Chrysomyinae. To assist forensic entomologists, ecologists, and public health workers, we provide a key to 3rd instars of 8 chrysomyine species reported from or likely to(More)
The minimum developmental rates of Protophormia terraenovae (Robineau-Desvoidy) and Calliphora vomitoria (L.) were measured at four temperatures: 12.5, 23, 29, and 35 degrees C. Although both species are Holarctic in distribution and hemisynanthropic, there are important differences in the response of their developmental stages to various temperature(More)
Length of the oldest maggots recovered from a body often provide an accurate estimate of the time since death. The length of maggots of Protophormia terraenovae (Robineau-Desvoidy) of known age, at peak of feeding, was measured after 5 days immersion in one of 15 killing and preservative solutions, some of which are routinely used at autopsy and in forensic(More)
Until recently, the two biologically equivalent blow flies Chrysomya albiceps (Wiedemann) and Chrysomya rufifacies (Macquart) had disjunct distributions outside the Americas; the former was Palaearctic, the latter Australasian and Oriental. The two species are now spreading throughout the Americas and coexist in Argentina. The predatory "hairy" larvae of(More)
Seven species of Calliphoridae are reported from the Galápagos Islands, Ecuador: Lucilia pionia (Walker), L. setosa (James), L. deceptor (Curran), L. eximia (Wiedemann), Cochliomyia macellaria (Fabricius), Chrysomya albiceps (Wiedemann), and Chrysomya megacephala (Fabricius). Lucilia eximia is newly recorded from the islands. Lucilia sp. near pionia is(More)
The Nearctic species of Calliphora Robineau-Desvoidy are revised and all species are redescribed and/or diagnosed. Diagnostic characters to permit reliable identification of both sexes of Calliphora aldrichia (Shannon) and C. montana (Shannon) and detailed distributional records for both species are provided for the first time. A lectotype is designated for(More)
