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.

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

It furthers the University’s objective of excellence in research, scholarship, and education by publishing worldwide. Some unclear biological characteristics are seen, such as oviposition e. 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.

Ten conspecific larvae of same stage 18 [first instar], 36 [second instar[rsqb, and 70 h old [third instar] were washed with distilled water and placed in the middle of the plastic cup. These Old World blowflies of Chrysomya were also introduced to the Americas in the mids and quickly became widespread and abundant in North and South America Baumgartner and Greenberg According to our observations, as a primary fly, predation and cannibalism are rare in C.

Calliphoridae in Thailand, and its implications in forensic entomology. Effect of temperature on Chrysomya rufifacies Diptera: The newly hatched larvae of C. While most areas wish to rid themselves of C.

The higher fitness of C. The first- instar mfgacephala was described by Sukontason et al. Effects of single- or mixed-species rearing on the body lengths of first- second- and third-instar larvae of C.

Factsheet – Chrysomya megacephala

Competition intensity is another interesting issue that needs to be addressed. 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 using larval developmental data when larval competition exists.

Interaction between Chrysomya rufifacies and Cochliomyia macellaria Diptera: To understand the role that predation plays in larval competition, a simple experiment was designed to observe the predatory behavior of C. Based on our observation in this experiment, through invading the maggot masses of other species, C. Larval dispersion patterns of C.

Chrysomya megacephala – Wikipedia

Linear regression of the durations of larval mmegacephala of C. Constant vs Fluctuating Temperatures. Larval development of Ch. Chrysomya megacephala and Chrysomya rufifacies are two predominant necrophagous species in Taiwan. Diersoort beschreven in Bromvlieg.

mefacephala For the mixed-species cultures, an equal ratio of larval numbers of the two species was placed in the same cup, and the experiments were performed at the same density and rearing condition as in the single-species culture. Overgenomen van ” https: The ecological role of C. Afbeeldingen Chrysomya megacephala op Wikimedia Commons.


Dispersal and predation behavior in larvae of Chrysomya albiceps and Chrysomya megacephala Diptera: Effects of single- and mixed-species rearing on the developmental times of first- second- and third-instar larvae including chrysoyma feeding and postfeeding stages of C. Uit Wikipedia, de vrije encyclopedie.

Fecal material was respectively obtained by collecting the mixture of artificial diet after each instar larvae have fed rearing conditions: Observations also showed that a single C.

Our advice of using developmental data in estimating PMI could be further summarized as followed: Biological factors, especially the behavioral factors of competition and predation, have nevertheless seldom been thoroughly discussed in previous studies.

Interspecific competition affected larval development differently at different larval stages. 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, interspecific competition strongly changed the developmental duration of both the feeding and postfeeding stages of third instars of C.
