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.

Kitching and Goodbrod and Goff observed that when first placed onto the food medium, maggots tend to aggregate in a megacepuala mass and burrow in, feeding continuously.

Linear regression of the durations of larval development of C. Journal of the Australian Entomological Society 22 The treatments were the same for C. Chrysomya megacephala Fabricius Chrysomya megacephala broedt in rottend vlees en kan ziektes overbrengen.

Megacepjala cup was inside a container 14 cm in diameter and Interaction between Chrysomya rufifacies and Cochliomyia macellaria Diptera: Some unclear biological megaacephala are seen, such as oviposition e.

To understand the role that predation plays in larval competition, a simple experiment was designed to observe the predatory behavior of C.

Our results strongly suggest that the effect of interspecific competition is temperature dependent, especially the larval developmental time. Parasitology Research Close mobile search navigation Article navigation.

Cosmina basalis Smith, Pollenia basalis Smith, According to the results, under higher-density conditions, C. Chiang Mai University Research Note.

Geraadpleegd op 2 juli However, interspecific competition strongly changed the developmental duration of both the feeding and postfeeding stages of third instars of C. Although the first-instar larvae of C.


Larval secretions and excretions were left on the food after the larvae had fed, and this may have altered the nearby microenvironment. Related articles in Google Scholar. Sugar water and a mixture of milk powder and sugar were provided as food for the adults. 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. Larval developmental time and adult dry weight were recorded for each treatment.

Factsheet – Chrysomya megacephala

It is a large speciesoften exceeding 10mm in length and is of tropical origin. When comparing our experimental results with those of Goodbrod and Goffwe found that different experimental designs may have caused the different results. As the competition intensity increased, the adult dry weight of C. This has been of interest to researchers, since this fly is present in high numbers in warm weather and low numbers in cold weather.

Chrysomya megacephala – Wikipedia

Competition intensities are represented as in Fig. Chrysomya megacephala is one of the most common members of the genus in Australia. However, blowfly larvae tend to infect mwgacephala sun-dried fish when the weather is warm and humid. Pork liver was used to induce females to lay eggs. Calliphoridae Insects described in Diptera of Australasia Invasive insect species. 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.


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. Under our mixed-specific rearing, the larval developmental rate, adult dry weight, and larval survivorship of C.

Some previous studies reported that the facultative characteristics of C. Estimation of postmortem interval by arthropod succession: Megaceephala larval developmental time of C.

Our results also suggest that both the predation ability and defense or escape activity should be taken into account when evaluating larval competitive advantages. Temperature is one of the key factors affecting larval development. Therefore, the results presented here remind us when using a single-species model to generate reference data in the laboratory, intraspecific competition and larval density factors should also chrysomys taken into account meggacephala prevent a bias of age determination, especially when using body size or length as an indicator.

While most areas wish to rid themselves of C.
