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.

Chrysomya megacephala – Wikipedia
However, our results did not completely agree with previous studies, and we suspect that the difference was chrysomta caused by different experimental designs and different biological characters of different blow fly colonies. Most recorded miasis cases, however, do not involve the fly. Temperature, larval stage, and competition intensity are three newly proposed factors that have not been discussed in previous studies on interspecific competition.
The fecal material 1 g from C. Chrysomya rufifacies Macquart as a forensic-important fly species in Chrysomga The higher fitness of C.
Factsheet – Chrysomya megacephala
The larval developmental time of C. This causes losses in cattle and fish industries all over the world. Although the mechanism of how the competition intensity really works on these two species is still unknown, we found that the effect meacephala actually profound and should not be overlooked in evaluating larval developmental condition.
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.
In general, under mixed-species rearing at different temperatures and densities, larval duration, adult dry weight, and survivorship of both species decreased. Molecular identification of forensically important blow fly species Diptera: Calliphoridae in the laboratory: Kitching and Goodbrod and Goff observed that when first placed onto the food medium, maggots tend to aggregate in a single mass and burrow in, feeding continuously.
This means that interactions caused by these two megacdphala primary fly species, such as competition and predation, may frequently play important roles in the successional dynamics of this early carrion faunal assemblage.
Effects of single- or mixed-species rearing on the body lengths of first- second- and third-instar larvae of C. Larval predation of third instars of C. October Learn how and when to remove this template message.

Medical and veterinary Entomology 27 This species is found across northern Australia and also occurs commonly in south-east Asia. The results also imply the invasion of maggot masses of C. Dispersal and predation behavior in larvae of Chrysomya albiceps megacsphala Chrysomya megacephala Diptera: 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.
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.
Mature third instars were transferred onto sawdust for pupation. Diersoort beschreven in Bromvlieg. One possible explanation is that C. 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. Some previous studies reported that the facultative characteristics of C.
The results indicated that a temporary competitive advantage could only be obtained by C. In our studies, both species of C. The life table chryeomya mass rearing of Chrysomya megacephala Fabricius. It is a warm-weather fly with a greenish-blue metallic box-like body. However, interspecific competition strongly changed the developmental duration of both the feeding and postfeeding stages of third instars of C.
A Single third instar of C. Developmental duration, survivorship, and adult dry megxcephala were recorded for each treatment. Handbook of Food Science, Technology, and Engineering. The survivorships of C. Linear regression was used to determine the effects of different competition intensities on larval development.
