“…According to some studies, the size and shape of the wings may be related to environmental characteristics, such as temperature [69][70], although, according to other authors, interspecific changes in size and shape have a closer relationship with genotypic variation, considering that there is a genetic basis for explaining these characteristics [71][72]. Considering several studies [73][74][75], the difference in wing variation found in the present samples could be due to interspecific competition, larval dispersal, and substrate colonization. Growth patterns can vary widely, both among and within species, even when environments are similar [76].…”

“…Smaller larvae travel greater distances to pupariate or in search of an additional food source. Postfeeding dispersal in blow fly larvae under laboratory conditions is typically very short but may extend for hours or even days in the field [19]. The postfeeding larval dispersal behavior and the consequent pattern of spatial distribution of pupae can be a function of greater or lesser larval susceptibility to predator or parasitoid attacks [7,11,20,21,22].…”

The blow fl y larvae leave the food source after reaching maturity, and begin to disperse in order to fi nd suitable places for pupariation, a process commonly called postfeeding larval dispersal. Some important aspects of this process were studied by allowing the postfeeding larvae of Chrysomya megacephala (Fabricius) and Chrysomya rufi facies (Macquart) to disperse from the center of a circular arena. The arena was divided into 4 circles starting from the center in order to determine the location of each pupa. The relationship between distance from the center and the weight of each pupa was evaluated statistically. It was observed that the lighter larvae tend to move longer distances. The greatest concentration of pupae was found in distances lesser than 100 cm in both the species though it was more evident in case of C. rufi facies. The study of this dispersal process can be important while estimating the minimum postmortem interval (PMI) of human cadavers during forensic investigations.

“…These blowflies of the genera Chrysomya (Diptera: Calliphoridae) are of considerable medical and sanitary importance since it is a myiasis producing agent in animals as well as humans. These flies are also important in forensic entomology since they can be used as biomarkers to estimate the Post Mortem Interval [8][9][10].…”

The present study deals with the effects of variation in temperature and humidity on the different life cycle stages of Calliphoridae fly Chrysomya saffranea. In India for first time, Chrysomya saffranea was recorded apart from Australia as a native place of this fly.In this study different life cycle stages of Chrysomya saffranea in different seasons were observed. In summer season when the average temperature ranged between 30.5°C and 33.2°C and the average humidity ranged between 12% to 19%, life cycle duration was completed in 220 h (9.17 days) from the depositing of eggs up to the eclosion of adults. But in rainy season when the average temperature ranged between 25.6°C and 28.9°C, and the average humidity ranged between 50% to 65%, life cycle duration was completed in 259 h (10.79 days), while in winter season when the average temperature ranged between 17.8°C and 24.4°C, and the average humidity ranged between 17% to 28%, life cycle duration was completed in 341 h (14.21 days) from eggs up to emergence of the adults.The temperature and humidity are the most important factors playing role in the larval development, decay and degradation of the cadavers. Therefore, the climatic fluctuations and environmental changes play an important role in the life cycle of Chrysomya saffranea. All these factors must be considered in the Post Mortem Interval determination.
