Chrysomya megacephala (Fabricius, ) occurs on every continent and is closely associated with carrion and decaying material in human. The Oriental Latrine Fly, Chrysomya megacephala Fabricius, , is notorious in this regard. Adults of the synanthropic form of this species (see below) are. Abstract. Chrysomya megacephala and Chrysomya rufifacies are two predominant necrophagous species in Taiwan. Larvae of the latter can prey on other.

Larval Competition of Chrysomya megacephala and Chrysomya rufifacies Diptera: This means that interactions caused by these two coexisting primary fly species, such as competition and predation, may frequently play important roles in the successional dynamics of this early carrion faunal assemblage. It is a warm-weather fly with a greenish-blue metallic box-like body. Effects of different breeding densities on the duration of larval development Aadult dry weight Band larval survivorship C under single-species rearing of C.

Chrysomya megacephala – Wikipedia

However, the cross-effect of temperature and competition is still unclear; our preliminary conclusion was that the interaction is probably caused by different degrees of temperature durability in the two species. As the competition intensity increased, the adult dry weight of C. In andere projecten Wikimedia Commons Wikispecies.

As Ullyett mentioned, a fly of smaller growth weight required a smaller quantity of food for full development; its more rapid and earlier development on carrion has a distinct advantage over other species in the acquisition of food. The survivorships of C. Email alerts New issue megscephala.


This fly is implicated in some public health issues; it can cause accidental myiasis[1] and also infects fish and livestock.

We used the product of the mean adult dry weight and the mean larval survivorship as indicators for the overall fitness of these flies; the results showed that the fitness levels of both species were lower under interspecific competition than under intraspecific competition and gradually decreased as larval densities increased Fig. Oxford University Press is a department of the University of Oxford.

Estimation of postmortem interval by arthropod succession: Both of these species did contain megacphala, but there had been no previous record of organophosphates in their larvae. Deze pagina is voor het laatst chryomya op 2 dec om The objectives of this study were to provide more detailed larval developmental and behavior data under intra- and interspecific competition and different temperature effects and to try to determine factors affecting competition when using these developmental data to estimate the PMI.

cnrysomya However, in actual applications, data on the initial population or species composition and proportion on a carcass are difficult to acquire, thus making this correction hard to apply in most real cases. Calliphoridae in Thailand, and its implications in forensic entomology. When comparing our experimental results with those of Goodbrod and Goffwe found that different experimental designs may have caused the different results.

Reigada and Godoy performed an experiment to understand the dispersal and predation behaviors of blow fly larvae in mixed-species culture; their results showed that C. The immature stages of the Old-World screw-worm fly, Chrysomya bezziana Villeneuve, with comparative notes on other Australasian species of Chrysomya Diptera: They also believed that the movement of numerous mouthhooks combined with the secretions of larval salivary and proteolytic enzymes increase the efficiency of the feeding process and the rate of larval development.
