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.

In general, under mixed-species rearing at different temperatures and densities, larval duration, adult dry weight, and survivorship of both species decreased. The fly infests corpses soon after death, making it important to forensic science. The developmental time of 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.

This section includes a list of referencesrelated reading or external linksbut its sources remain unclear because it lacks inline citations. Deze pagina is voor het laatst bewerkt op 2 dec om Linear regression was used to determine the effects of megaceohala competition intensities on larval development.

Harvard University Press, Related articles in Google Scholar. It furthers the University’s objective of excellence in research, scholarship, and education by publishing worldwide. Chrysomya megacephala and Ch.

Studying larvae from decomposed remains may provide an effective method of determining the presence of these toxins in a body that is extremely decayed. The habitat or “ecological islands” of animal carrion are small and distinct, and communities developing within them have at their disposal a limited amount of energy, which is gradually used up by the activities of the community members Beaver Fecal material was respectively obtained by collecting the mixture of artificial diet after each instar larvae have fed rearing conditions: Forty larvae per 60 g of medium were reared under five temperature treatments.


The maximum reduction was The maximum reduction time was Effects of different breeding densities on the duration of larval development Aadult dry weight Band larval survivorship C under single-species rearing of C.

The range 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 Greenberg ablarval predation Faria et al.

Chrysomya megacephala – Wikipedia

Competition intensities are represented by the number of individuals of the different species; 10, 20, and megacrphala are the respective numbers of individuals of the different species in each treatment of 40 larvae total.

Afbeeldingen Chrysomya megacephala op Wikimedia Commons. Biology Chrysomya megacephala is one of the most common members of the genus in Australia. They pointed out that the response of Hemipyrellia ligurriens to larval competition was clearly of the second type. The fly larvae of Chrysomya megacephala and Chrysomya rufifacies were also present at the scene on the body and were tested for megacepala.

As for larval survivorship, the survivorship of C. Larval development of Ch. Linear regression of the adult dry weights of C. Constant vs Fluctuating Temperatures. The objectives of this study were to provide more chrrysomya 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.


This has been of interest to researchers, since this fly is present in high numbers in warm weather and low numbers in cold weather. Msgacephala explanations are given in the following sections discussing ecological and behavioral aspects.

Factsheet – Chrysomya megacephala

View large Download slide. Chrysomya megacephala is one of the most common members of the genus in Australia. Larval predation of third instars of C. Chrysomya megacephalamore commonly known as the oriental latrine flyis a member of the family Calliphoridae blowflies.

Some unclear biological characteristics are seen, such as oviposition e. Chrysomya megacephala Female C. The “bath” was to try to remove any “odor” of the larvae in advance. Five larvae of the same instar stage from each species were placed into a ml plastic cup without food.

The first- instar larva was described by Sukontason et al. Developmental duration, survivorship, and adult dry weight were recorded for each treatment. A correlation between wing size and temperature as well as tibia size and temperature has also been found in this species.

Higher temperatures generally enhance the effects of interspecific competition, because high temperatures speed up the developmental rates of both species and also change their responses to competition.
