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.

The cup was inside a container 14 cm in diameter and From Wikipedia, the free encyclopedia. Calliphoridae Insects described in Diptera of Australasia Invasive insect species.

The developmental time of C. Chrysomya rufifacies Macquart as a forensic-important fly species in Thailand: Handbook of Food Science, Technology, and Engineering.

Calliphoridae has reached the continental United States: Geraadpleegd op 2 juli Larval competition for patchy resources in Chrysomya megacephala Dipt, Calliphoirdae: Laboratory interaction between introduced Chrysomya rufifacies and native Cochliomyia macellaria Diptera: Kitching and Goodbrod and Goff observed that when first placed onto the cjrysomya medium, maggots tend to aggregate in a single mass and burrow in, feeding continuously.

Despite this predation on Chrysomya megacephalaboth species had a lower survival rate, lighter adult weight and pupated early. Competition intensity is another interesting cbrysomya that needs to be addressed.

However, interspecific competition strongly changed the developmental duration of both the feeding and postfeeding stages of third instars of C. Larval developmental time and adult dry weight were recorded for each treatment. As for larval survivorship, the survivorship of C.


Molecular identification of forensically important blow fly species Diptera: The results indicated that a temporary competitive advantage could only be obtained by C. Distribution This species is found across northern Australia and also occurs commonly in south-east Asia. Ceylon Journal of Science 25 Problem megacepuala estimation of postmortem interval resulting from wrapping of the corpse: In any part of the world that uses organophosphatesC.

Chrysomya megacephala and Ch.

All of the above reasons led us to conclude that C. Uit Wikipedia, de vrije encyclopedie.

Factsheet – Chrysomya megacephala

It is a warm-weather fly with a greenish-blue metallic box-like body. Pork liver was used to induce females to lay eggs. The mixture of the artificial diet and larval products fecal material was collected to test its jegacephala on the movement orientation of larvae of both species.

Observations also showed that a single C. A Single third instar of C.

So and Dudgeon proposed two different responses of dipteran larvae to intraspecific competition: 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. Adults breed mostly in carrionbut they chtysomya also attracted to garbage and faeces.


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.

In tropical populations, such as in Brazilfertility is also lower in areas with high densities of larvae, where many in one small area compete for the same food source. Effects of single- or mixed-species rearing on the body lengths of first- second- and third-instar larvae of C. In many forensic entomology cases either C. However, our results did not completely agree with previous studies, and we suspect that the difference was partially caused by different experimental designs and different biological characters of different blow fly colonies.

Forty larvae per 60 g of medium were reared under five temperature treatments. The fly larvae of Chrysomya megacephala and Chrysomya rufifacies were also present at the scene on the body and were tested for malathion. Biological factors, especially the mebacephala factors of competition and predation, have nevertheless seldom been thoroughly discussed in previous studies.
