Keywords: excretory and secretory (ES), protein profile, third stage larva, identification, flies 1. CRC Press, New York. Apart from discriminating species into phenetic groups, GM also covers ontogenetic allometry which can explain how morphological variation attributes directly to growth (Klingenberg 1998). In these areas sun-drying is the major method of preserving fish, as ice is typically unaffordable. https://doi.org/10.1111/j.1948-7134.2012.00200.x, Kurahashi H, Benjaphong N, Omar B (1997) Blow flies (Insecta: Diptera: Calliphoridae) of Malaysia and Singapore. Forensic Sci Int 179(1):1–10. 2015). 2006; Gunz and Mitteroecker 2013; Changbunjong et al. In forensic entomology, cephalopharyngeal skeleton plays a crucial role in species identification but the morphometric information of this part is scarce. The coordinates are clustered based on the larval-age group sample. Additionally, this species also played a significant role in bacterial and parasitic transmissions in humans (Sulaiman et al. In many forensic entomology cases either C. rufifacies or Chrysomya megacephala are found on the decaying corpse; mitochondrial DNA is the main method used to determine which subfamily is present. Nevertheless, a medical examiner in Hawaii worked on a case in which poisoning by malathion, an organophosphate insecticide, was thought to be the cause of death. 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). Doe, Peter E. "Fish Drying and Smoking" Production and Quality. 2009.  C. megacephala is a carrier of pathogens, such as bacteria, protozoan cysts, and helminth eggs, to human food, because it lays its eggs on human feces, and will land on human food soon after. Scatter plot along CV1 (97.229%) and CV2 (2.179%) axes shows the variation in cephalopharyngeal skeleton shapes grouped by equal frequency ellipse (p = 0.9). A Taphonomic Model of Concealment: Decomposition and the Postmortem Interval (PMI) in a 55-Gallon Barrel. The “lollipop” diagram with dots indicate the average starting shape and the lines are the movement of landmark to the target shape. Forensic Sci Int 138:50–61. In the present study, the geometric morphometric analysis produced a visual classification of C. megacephala cephalopharyngeal skeletons based on their age groups. Cephalopharyngeal skeletons were removed from larvae and mounted on glass slides. Identification of the insect species requires the insect to develop into adulthood.

Larvae vary in size according to instar and are shaped more thickly towards the rear. , C. megacephala has a beneficial and practical value apart from being significant in forensic investigations; this blowfly is the source of pollination for mangos in the Australian region. Trop Biomed 21(2):69–75, CAS Pairwise comparison of centroid sizes between sampling intervals indicated the shape mostly transformed during early developmental stages (Table 2). Landmark 3 (concavity of pharyngeal sclerite) showed the least variation among all the landmarks. In addition, these changes explained by the ontogenetic allometry in C. megacephala larva were represented by the cephalopharyngeal skeleton. Pearson correlation test was used to determine the significant relationship between centroid size and developmental time. megacephala. 2001. https://doi.org/10.1007/s00427-016-0539-2, Kumara TK, Disney RHL, Abu Hassan A, Flores M, Hwa TS, Mohamed Z, Che Salmah M, Bhupinder S (2012) Occurrence of oriental flies associated with indoor and outdoor human remains in tropical climate of North Malaysia. Introduction The fly larvae of Chrysomya megacephala (Diptera: Calliphoridae), Achoetandrus rufifacies (Diptera: Callipho-ridae), However, for future studies, we recommend using an equal amount of sample size between groups and to reassess the GM landmarks. https://doi.org/10.1007/s00414-012-0683-9, Rocha DS, Patterson JS, Sandoval CM, Jurberg J, Ângulo VM, Esteban AM, Galvão C (2005) Description and ontogenetic morphometrics on nymphs of Belminus herreri Lent & Wygodzinsky (Hemiptera: Reduviidae, Triatominae). A female fly may lay as many as 200 to 300 eggs, often in human feces, meat or fish. Subsequently, CVA was employed to describe shape variations between age groups by maximizing the effect of separation (Cooke and Terhune 2015).  The fly has been found in California, as well as Texas, Louisiana, and Hawaii. Forensic investigations and the estimation of human postmortem intervals (time since death) depend on the identification of blow fly larvae on a corpse and their approximated age. (1997) while the subsequent larval species were determined based on Barros-Cordeiro and Pujol-Luz (2010) and Sukontason et al. A matter of concern that demands further investigation is the coplanarity of landmarks on cephalopharyngeal skeleton, as the actual three-dimensional shape could have been distorted when projected as a two-dimensional image. C. megacephala is the most abundant blow fly species surveyed in Chiang Mai (78.02%), and to a lesser extent, C. rufifacies (16.80%) (Lertthamnongtham et al. Chrysomya megacephala (Fabricius) (Diptera: Calliphoridae) is a common and forensically important blow fly species in the Oriental region. Forensic Sci Res 3(1):2–15. 2007. 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. The aim of this study is to identify eggs of species of forensic importance, such as Chrysomya megacephala, Chrysomya putoria, Lucilia cuprina, Lucilia eximia and Ophyra aenescens, using scanning electron microscopy (SEM https://doi.org/10.1111/j.1755-0998.2010.02924.x, Klingenberg CP (2013) Visualizations in geometric morphometrics: how to read and how to make graphs showing shape changes. 1 B and C). Sim, LX., Zuha, R.M. This effect accounted for 60.3% of the total shape variation. Both species of flies have evolved with various species of pathogenic bacteria in humans, so it is very potential to transmit new species of pathogenic bacteria in humans 1,12. "Forensic Entomology; The Utility of Arthropods in Legal Investigations" Pg. The cephalopharyngeal skeleton was subsequently immersed in 10% acetic acid and 70% ethanol for 5 min each. Hystrix It J Mamm 24(1):103–109. Studying larvae from decomposed remains may provide an effective method of determining the presence of these toxins in a body that is extremely decayed. Based on the conditions of slit on posterior spiracle which could be used to discern larval instars (Barros-Cordeiro and Pujol-Luz 2010), C. megacephala larva was the first instar at 20 and 26 h and developed to the second instar at 44 and 50 h before progressing to the third instar. https://doi.org/10.1186/s41935-018-0070-x, Gidaszewski NA, Baylac M, Klingenberg CP (2009) Evolution of sexual dimorphism of wing shape in the Drosophila melanogaster subgroup.

In laboratory studies conducted at 27 °C., eggs hatch in 18 hours; the first molt occurs in 30 hours; the second molt in 72 hours; pupation after 144 hours; and the adult emerges after approximately 234 hours. Chrysomya megacephala are close ancestors and monophyletic which means that they are genetically similar but the morphological appearance of these … In tropical populations, such as in Brazil, fertility is also lower in areas with high densities of larvae, where many in one small area compete for the same food source. Raja M. Zuha. 2011; Mitteroecker et al. Chrysomya albiceps is also known to prey on C. megacephala during the larval stage when they must compete for the same food source.

They were left exposed and checked hourly for ovipositon activity by a single female C. megacephala. Due to the allometric effect, we reran cross-validation test on the groups without the effect of size on the morphological changes by using residuals from multivariate regression analysis (Klingenberg 2016). It is most common in the Oriental and Australasian realms. If only C. rufifacies is found on a body, it is not accurate to use only this species to calculate a time of colonization. Cephalopharyngeal skeleton was obtained by removing larval internal content and adhering tissue in 10% potassium hydroxide (KOH) (Rabbani and Zuha 2017). Infect Genet Evol 8(6):875–890. 2017). This allometric effect has been reported in other organisms and the relationships vary and were usually high during ontogenesis (Rocha et al. Parasite Vector 10(55). Southeast Asian J Trop Med Public Health 31(Suppl 1):157–161, PubMed In recent years, geometric morphometrics (GM) has been increasingly utilized as a multivariate tool to classify insect species based on morphological shape in both mature and immature stages including flies (Canal et al. Larval dispersion patterns of C. megacephala also make it forensically important. Texas A&M University, College Station. https://doi.org/10.1016/j.forsciint.2003.08.010, Article Chrysomya megacephala The analysis of eggs shows dorsal concave surface with a continuous median area, extending from one end to the other ( Fig. Google Scholar, Bookstein FL (1991) Morphometric tools for landmark data: geometry and biology. Studies are being done on C. megacephala to determine its role as a vector for diarrhea-causing bacteria such as E. Chrysomya Robineau-Desvoidy is one of the most forensically important blow fly genera. 2018). When C. rufifacies and C. megacephala larvae are put into cultures separately from one another in high densities, C. megacephala has a higher rate of survival than C. rufifacies. Chrysomya megacephala, more commonly known as the oriental latrine fly, is a member of the family Calliphoridae (blowflies). https://doi.org/10.14411/fp.2016.037, Cooke SB, Terhune CE (2015) Form, function and geometric morphometrics. https://doi.org/10.1002/ar.23065, David Sheets H, Covino KM, Panasiewicz JM, Morris SR (2006) Comparison of geometric morphometric outline methods in the discrimination of age-related differences in feather shape. Plos One 6(10):e25630.  Knowledge of larval competition is also useful in forensic studies, because it could affect the estimate of the time of death. 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. have a potential to estimate age of immature C. megacephala, and possibly in other flies species, and might further be used to determine the PMI. 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. 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). 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. Adults are mechanical carriers of a range of pathogens [ 1, 2, 3] and their larvae can cause myiasis in humans and animals [ 4, 5 ]. Smith JL(1), Wells JD(1). The scatter plot from CV1 and CV2 shows that the cephalopharyngeal skeletons of C. megacephala at 20- and 26-h age group was clearly isolated from those at 44- to 92-h group. We hypothesized that centroid size correlates with developmental time and varied independently between age groups. Journal of Medical Entomology 34: 353–358.  Population numbers as well as body size are greatly influenced by temperature. 2012). Indian J For Med Toxicol 11(2):217–221. It is also possible to tilt the cephalopharyngeal skeleton form dorsally or ventrally to explore shape variation as object symmetry (Klingenberg 2002), i.e., the alternate view to asymmetrical lateral shape as in the current study. C. megacephala is not predaceous in the adult or larval form, preferring to feed on necrophagous material of any kind, such as fish, cows and humans.  The cercus of the male is longer than that of the female. 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).

Lee Goff. The Calliphoridae species Chrysomya megacephalaand Chrysomya rufifacieswere reared in laboratory condition for studying their time duration of different stages … 3). The third instar of C. rufifacies will eat Chrysomya megacephala when the larvae are in high density. Pharr, Lauren R. 2009. On the following day, at 0900 hours, newly emerged first instar larvae were transferred evenly into five freshly prepared rearing containers labeled as day 1 to day 5. 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%. Larva: Fully mature third instar muscoid-shaped (11 mm length), composed of 12 segments with pointed anterior and blunt posterior end (Fig. Forensic insect field identification cards. Anat Rec 298:5–28.  The adult lifespan of the fly is approximately seven days. Both authors read and approved the final manuscript. In replicate 1, differences were detected between the 44- and 50-h group, 68- and 74-h group, 68- and 92-h group, and 74 and 92-h group.  The flies can be controlled by using an odor that the flies are attracted to trap them. PubMed This scope of application in GM could be useful to describe the growth of forensically important insects. In contrast with its body length, the measurement based on cephalopharyngeal skeleton morphometry was more reliable and consistent to be used as growth parameter in forensic entomology (Rabbani and Zuha 2017; Eliza and Zuha 2018). saffranea, Ch. Correlation between centroid size of C. megacephala cephalopharyngeal skeleton and developmental time indicated that it can be used as a growth parameter which could be applicable for mPMI estimation.

In: McAlpine JF, Peterson BV, Shewell GE, Teskey HJ, Vockeroth JR, Wood DM (eds) Manual of Nearctic Diptera, vol 1.  Larval stages include first, second and third instals or growth periods. The developmental period of C. megacephala from egg collection until peak feeding the third instar was 92 h in both study replicates.  Insecticides are also used, although this results in the development of resistance. The larval age is estimated based on their growth parameter such as larval body length, which can be inferred from the species-specific developmental model (Sharma et al. The disadvantages of morphological taxonomy have resulted in numerous synonyms and caused problems in the species identification of this genus. Chrysomya megacephala larvae were used as sample, as this species was one of the most prevalent sarcosaprophagous species found at death scenes in Malaysia, Thailand, and the rest of the world (Lee et al. Chrysomya megacephala is widely distributed over the Oriental and Australasian regions, also occurring in many neighbouring parts of the Palaearctic Region (Zumpt 1965). We also wish to thank Ms. Sharifah Shakilah Abdullah for her kind assistance during research. Jason H. Bryd, James L. Castner. 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.
