The objective of this work was to evaluate some aspects of the populational ecology of Chrysomya megacephala, analyzing demographic aspects of adults kept under experimental conditions. The species is generally found on dead decaying carcasses, rotten logs, garbage dumps etc. 2017) while in the larval stages, Nuñez and Liria (2016) successfully differentiated C. megacephala, Chrysomya albiceps (Wiedemann 1819), and Lucilia cuprina (Wiedemann 1830) by using a similar approach.

Larvae vary in size according to instar and are shaped more thickly towards the rear. Additionally, this species also played a significant role in bacterial and parasitic transmissions in humans (Sulaiman et al. Covers ranges, e.g., a global range, or a narrower one; may be biogeographical, political or other (e.g., managed areas like conservencies); endemism; native or exotic. However, there were no significant differences detected between groups sampled on the same day such as group 20 and 26 h (day 1), group 44 and 50 h (day 2), group 68 and 74 h (day 3), and group 74 and 92 h (day 4).

This fly can be a nuisance to humans and even cause accidental myiasis. In Calliphoridae larvae, cephalopharyngeal skeleton is the invaginating mouthparts in the cephalic region of the larva, consisting of pharyngeal sclerites and mandibles which are used to facilitate food intake (Teskey 1981). Along CV2 (2.2%), landmark 1, 3, and 5 dispositions were amplified. 2007). We also wish to thank Ms. Sharifah Shakilah Abdullah for her kind assistance during research.

There were also no significant differences between 68 and 74 h (day 3) with 92 h (day 4). The ontogenetic allometry, i.e., the relationship between size and shape across different ages, and visualization of landmark dispositions were also performed by using prescribed methods (Klingenberg 2013; Mitteroecker et al. Mahalanobis and Procrustes distances by pairwise comparisons of all age groups showed significant differences between daily intervals (permutation 10,000 rounds in MorphoJ: p < 0.0001) (Table 3). Eggs were reared overnight at outdoor ambient temperature (23.5–34.0 °C) and relative humidity (RH) (44.0–96.0%).

However, for future studies, we recommend using an equal amount of sample size between groups and to reassess the GM landmarks. Bull Ent Res 79(4):625–629. Green flies (Chrysomya megacephala) perch on rotten food, fish that begin to rot and rubbish and rotten carcasses.

Pictured in Dar es Salaam, Tanzania. - 103.129.223.144. Description: English: A male Chrysomya megacephala. Correlations between centroid size and cephalopharyngeal skeleton developmental time were determined by using Pearson’s correlation test. In forensic entomology, cephalopharyngeal skeleton plays a crucial role in species identification but the morphometric information of this part is scarce. https://doi.org/10.4404/hystrix-24.1-6292, Klingenberg CP (1998) Heterochrony and allometry: the analysis of evolutionary change in ontogeny. For the first instar larvae, cephalopharyngeal skeletons were mounted directly on the glass slide without KOH and subsequent treatments because the specimens were too delicate. Through visual assessment of these five landmarks on C. megacephala larval development, transformation occurred at all landmarks with the least change on landmark 3 (the concavity of pharyngeal sclerite or medial incision). PubMed Central  Pearson correlation test was used to determine the significant relationship between centroid size and developmental time. Figure 2 displays shape changes along CV1 (97.2%) axis with landmark 2 (dorsal cornu) and 4 (ventral cornu) displaying the most variation, followed by landmark 1 (anterodorsal process) and 5 (base of parastomal bar). Cages of C. megacephala adults were prepared with four different larval densities (100, 200, 400 and 800). Description: Chrysomya is an Old World blow fly genus belonging to the family Calliphoridae. The regression function in MorphoJ was used to determine ontogenetic allometry which is the influence of size changes on the shape.
