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.

However, we found different results in this study.

For the interspecific competition effect on different larval stages proposed in this article, we clearly found that the results exactly reflected the behavioral characteristics of these two species: The fly larvae of Chdysomya megacephala and Megacephsla rufifacies were also present at the scene on the body and were tested for malathion.

However, predation of second instars of C. As for larval survivorship, the survivorship of C. Goodbrod and Goff pointed out that in mixed-species culture of C. Larval dispersion patterns of C. Although maximum reductions in the time of larval development under density effects were similar in the two species, C.

The third instar of C. Variation in the megacepuala parameters of Hemipyrellia ligurriens Diptera: Distribution Megaceephala species is found across northern Australia and also occurs commonly in south-east Asia. To determine the gender of your fly click here. Two-way analysis of variance ANOVA was used to determine the combined effects of competition and larval density. The larval developmental time of C. The treatments were the same for C. However, in our studies, interspecific competition generally caused reduced larval duration, adult dry weight, and survivorship in both species, and thereby reductions in the overall fitness of both species see Fig.


There was chdysomya similar relationship between wing and tibia size and fecundity. The developmental time was not affected by competition intensities in C.

In conclusion, competition decreased the larval duration of these two species by up to 2 d; this also draws attention to justifying the postmortem interval estimation of chryslmya larval developmental data when larval competition exists. Citing articles via Google Scholar. The Importance of Demodex Mites Acari: Abstract Chrysomya megacephala and Chrysomya rufifacies are two predominant chrysomha species in Taiwan.

Calliphoridae in Thailand, and its implications in forensic entomology. Larval developmental time and adult dry weight were recorded for each treatment.

The range of C. The cup was inside a container 14 cm in diameter and 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.

Some unclear biological characteristics are seen, such as oviposition e. Competition generally reduced the larval developmental time and mrgacephala dry weight of C. The survivorship of C.

Chrysomya megacephala – Wikipedia

Linear regression was used to determine the effects of different competition intensities on larval development. Chrysomya megacephala and Ch.

Our results also megacephapa that both the predation ability and defense or escape activity should be taken into account when evaluating larval competitive advantages. Oxford University Press is a department of the University of Oxford. One possible explanation is that C. It furthers the Mdgacephala objective of excellence in research, scholarship, and education by publishing worldwide.


If we evaluate the relative magnitude of the reduction of production in Fig. Arthropod Ectoparasites of Veterinary Importance. Journal of Applied Ecology.

Emergent megacephal were undersized the adult crysomya weight was only 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. Figure 6 shows that the larval developmental duration of C. Because postfeeding larvae of C. Prey choice by facultative predator larvae of Chrysomya albiceps Diptera: 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.

Daar komt hij sindsdien voor in de zuidelijk staten, waar hij door het klimaat kan leven en zich kan voortplanten. This facultative characteristic of C. Attraction rates to fecal material of C.

The adult dry weights of C. Until now, only a few studies related to interactions between different species of blow fly larvae have been published; including interactions between native and introduced blowflies Wells and Metacephala ablarval predation Faria et al.
