chrysomya megacephala description

We also performed regression test by using the Procrustes coordinates on log centroid size, resulting p < 0.0001 with improvement in the effect of the total shape variation of 65.7%. (2008). Hydrobiologia 670:5–22. 2017) or 3D morphometrics (Bai and Yang 2014). In: McAlpine JF, Peterson BV, Shewell GE, Teskey HJ, Vockeroth JR, Wood DM (eds) Manual of Nearctic Diptera, vol 1. rufifacies, Ch. Landmarks used for cephalopharyngeal skeleton shape description in the present study were limited to five landmarks instead of the eight used by Nuñez and Liria (2016), because of some clearly undeveloped structures in the first instar larvae such as apical hook, union between hypostomal sclerite and the mouth hook, and dorsal apodeme of mouth hook. PubMed  Landmark coordinates of cephalopharyngeal skeletons in study replicates 1 and 2 were pooled and further analyzed on thin-plate spline transformation grid and “lollipop” diagram (scale factor 10.0). Decay is caused by bacteria. The raw data were analyzed based on the age-stage, two-sex life table, in order to take both sexes and the variable developmental … The cephalopharyngeal skeleton was subsequently immersed in 10% acetic acid and 70% ethanol for 5 min each. The oriental latrine fly, Chrysomya megacephala (Fabricius, 1794), is a medically and forensically important blow fly species as its habit and breeding places are within or near to human settlements. Biol Rev 73:79–123. Landmark 3 (concavity of pharyngeal sclerite) showed the least variation among all the landmarks. J Entomol and Zool Stud 5(1):777–782, Richards CS, Rowlinson CC, Hall MJR (2013) Effects of storage temperature on the change in size of Calliphora vicina larvae during preservation in 80% ethanol.

Sources des 2 jeux de données. (1940). Cephalopharyngeal skeletons were removed from larvae and mounted on glass slides. This fly can be a nuisance to humans and even cause accidental myiasis. The landmark consist of 1 clipeal arc (anterodorsal process/dorsal bridge), 2 dorsal cornu, 3 concavity of pharyngeal sclerite (tentorial phragma/medial incision), 4 lower ventral cornu, and 5 base of parastomal bar (Nuñez and Liria 2016) (scale bar = 0.5 mm). Chrysomya bezziana is distributed widely in Southeast Asia, New Guinea, and Africa., Klingenberg CP (2011) MorphoJ: an integrated software package for geometric morphometrics. This study was conducted in two replicates in natural conditions, i.e., study replicate 1 from 14 August 2018 to 18 August 2018, and study replicate 2 from 24 September 2018 to 29 September 2018. Sim, LX., Zuha, R.M. 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. Media in category "Chrysomya megacephala" The following 30 files are in this category, out of 30 total. 2015). PubMed Central  In forensic entomology, cephalopharyngeal skeleton plays a crucial role in species identification but the morphometric information of this part is scarce. Pearson correlation test was used to determine the significant relationship between centroid size and developmental time. Chrysomya were collected throughout the sampling period. Trop Biomed 21(2):69–75, CAS, Sukontason K, Bunchoo M, Khantawa B, Pianjai S, Sukontason K, Methanitikorn R, Rongsriyam Y (2000) Mechanical carrier of bacterial enteric pathogens by Chrysomya megacephala (Diptera: Calliphoridae) in Chiang Mai, Thailand. … (1997) while the subsequent larval species were determined based on Barros-Cordeiro and Pujol-Luz (2010) and Sukontason et al. General description of the sites where the species is found (ecosystem, forest, environment or microhabitat). The life cycle: Egg, three instars, pre-pupa, pupa, adult. saffranea, Ch. The relationship between centroid size and age in ontogenetic allometry through multivariate regression analysis has been found reliable to explain biological shape changes across different ages including humans (Bulygina 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. Landmarks were selected based on geometrical shape of the cephalopharyngeal skeleton, i.e., (1) clipeal arc (anterodorsal process/dorsal bridge), (2) dorsal cornu, (3) concavity of pharyngeal sclerite (tentorial phragma/medial incision), (4) lower ventral cornu, and (5) base of parastomal bar (Nuñez and Liria 2016) (Fig. Google Scholar, Bai M, Yang X (2014) A review of three-dimensional (3D) geometric morphometrics and its application in entomology. Files are available under licenses specified on their description page. Furthermore, the selection of landmarks for GM analysis adhered to the criteria that they can be found repeatedly and not difficult to locate (Bookstein 1991; Zelditch et al. Background. Along CV2 (2.2%), landmark 1, 3, and 5 dispositions were amplified. Hystrix It J Mamm 24(1):103–109. Källor a b c; Externa länkar. In addition, these changes explained by the ontogenetic allometry in C. megacephala larva were represented by the cephalopharyngeal skeleton. On the ontogenetic allometric effect, regression analysis on the Procrustes coordinates on centroid size among age groups revealed a significant relationship between cephalopharyngeal skeleton shape variation and size (permutation 10,000 rounds in MorphoJ: p < 0.0001).

Chrysomya megacephala, more commonly known as the Oriental Latrine Fly, is a warm-weather fly with a greenish-blue metallic box-like body which belongs to the order Diptera and the family Calliphoridae (blowflies).

Parasite Vector 10(229). Egypt J For Sci 5(1):1–12. However, there were drawbacks when using larval body length because it can be affected by specimens handling (Tantawi and Greenberg 1993; Adams and Hall 2003; Day and Wallman 2008; Richards et al. collecté par Sonothèque du MNHN. Geometrical landmarks of C. megacephala cephalopharyngeal skeleton in three different instars. Post-feeding larvae were excluded from sampling. Article  PubMed  The Paleontological Society Papers 16:163–188. PubMed Central  We hypothesized that centroid size correlates with developmental time and varied independently between age groups. Apart from discriminating species into phenetic groups, GM also covers ontogenetic allometry which can explain how morphological variation attributes directly to growth (Klingenberg 1998). The cephalopharyngeal skeleton shape was profiled based on centroid size, i.e., the square root of the sum of squared distances between each landmark and the centroid of the cephalopharyngeal skeleton (Zelditch et al.
