“…The effects of temperature on larval growth in the present study are consistent with those in earlier studies on C. albiceps (Queiroz 1996;Vélez and Wolff 2008;Al-Shareef and Al-Qurashi 2016;Salimi et al 2018), supporting that higher temperatures accelerate larval growth, as also observed in other forensically important flies, such as Chrysomya megacephala (Fabricius, 1794) (Bansode et al 2016). The decrease in body length and weight at the last sampling period at each rearing temperature indicated the postfeeding phase, which is characteristic of the blowfly (Greenberg and Kunich 2002).…”

“…Later studies that analyzed C. albiceps under four constant rearing temperatures (20, 25, 30, and 35 °C) reported total larval stage durations of 9, 6, 4.83, and 4.75 days, respectively (Al-Shareef and Al-Qurashi 2016). The larval stages of those reared at 25 °C and 30 °C were 6 and 4 days, respectively (Salimi et al 2018); and the larval stages of those reared at 18, 22, 27, and 32 °C were 21.30, 10.61, 5.0, and 4.0 days, respectively (Queiroz 1996). These results are similar to those of studies on forensically important species of family Calliphoridae, such as Chrysomya pinguis (Bharti 2009).…”

“…The latter data are in line with those previously reported for C. albiceps in laboratory studies, where under four constant rearing temperatures at 20, 25, 30, and 35 °C, pupal periods of 7, 5.5, 4.00, and 1.50 days were recorded, respectively (Al-Shareef and Al-Qurashi 2016). Additionally, at 25 °C and 30 °C, the pupal periods were determined to be 5 and 3.5 days, respectively (Salimi et al 2018). Under laboratory conditions (28 °C and 40% RH), the C. albiceps pupation period ranged from 4 to 6 days (Shiravi et al 2011).…”

Background Chrysomya albiceps (Wiedemann, 1819) (blowflies), family Calliphoridae, is important in forensic entomology, where the minimum and maximum postmortem intervals (PMI) are estimated on the basis of the developmental stages of Diptera larvae that consume dead tissue. The present study was designed to estimate the effects of different ambient temperatures (20, 25, and 30 °C) under controlled laboratory conditions on the developmental stages of C. albiceps from the Jazan region, Saudi Arabia. Results The present study showed that the larval body weight and length were significantly increased when larvae were reared at 30 °C compared with corresponding values at 24 h, 48 h, and 72 h at rearing temperatures of 20 °C and 25 °C; however, the weight and length were significantly decreased compared with corresponding values at 96 h at 20 °C and 25 °C. The pupation time was inversely related to the rearing temperature, occurring at 144, 124, and 120 h at rearing temperatures of 20 °C, 25 °C, and 30 °C, respectively. The pupal weight and length were significantly increased in larvae reared at 30 °C compared with those reared at 20 °C and 25 °C. At 20 °C, 25 °C, and 30 °C, larval durations of 5.00, 5.00, and 4.00 days were recorded, respectively. Pupae and adults showed gradual decreases in life stage durations, at 6.00, 5.30, and 4.80 days in pupae and 20.00, 18.70, and 16.90 days in adults, with increasing rearing temperatures. Average adult longevity at 30 °C (194.40 h) was significantly less than adult longevity at 20 °C (216.00 h) and 25 °C (204.60 h). The results showed an inverse relation between durations of developmental stages and rearing temperatures. Conclusions Insect laboratory colonization for the determination of biological characteristics of insects is economically viable for forensic entomology and as a technique for evaluating insect evidence.

“…However, our findings contradict the results of Johl and Anderson (1996)'s. They reported that no mortalities occurred in any immature stages of C. vicina, including eggs and 1st stage larvae, when they were chilled to 3 ºC for 24 h. As noted in various studies, inherent biogeographical variation between populations, humidity, population density and other intrinsic factors can cause such differences (Saunders and Hayward, 1998;Salimi et al, 2018).…”

The purpose of this study was to evaluate the effects of four different chilling periods, varying from 24 to 120 h, on the mean survival rate, larval and pupal development durations and the pupal and adult weight of Calliphora vicina (Robineau-Desvoidy) (Diptera: Calliphoridae) under laboratory conditions at 4 ºC in 2018 at Ondokuz Mayıs University. Chilling reduced the survival rate of the pupae of all developmental stages. The adult eclosion rate of first instar larvae and pupae was lower, especially after 72 and 120 h chilling periods, but it increased for the second instar, third instar and postfeeding larvae with increasing chilling period. In addition, the larval development period was increased by increased chilling period for all developmental stages except for postfeeding larvae for 120 h. Pupal and adult weight were also affected by chilling period, and the postfeeding larval and pupal stages were the most intolerant groups to chilling. Overall, the effects of chilling on the life history parameters of C. vicina were substantial and should be considered to provide a more reliable estimate of postmortem interval.

“…The simulation model presented in this study highlights the importance of temperature and period of refrigeration on PMI estimation from specific fly species. The species used in this study include the most common taxa sampled from human cadavers and those which have been studied extensively for PMI estimations (8,(18)(19)(20)(21)(22)(23). Based on the findings of the present study, the temperature variations during refrigeration will result in continued development of fly larvae in a large proportion of cases.…”

The association between insect development and temperature is well established. Thermal summation using accumulated degree-day measures is commonly used. However, the time at which evidence is collected is important in these estimates. The aim of this study was to provide a simulated model of the effect of temperatures on six dipteran species commonly associated with cadavers, from the death scene to the refrigerator, and finally at the time of autopsy. Temperatures measurements were sampled over a 16-month period from the external environment (external to the mortuary), within the mortuary refrigerator, and within the mortuary autopsy suite. Monte Carlo simulation using accumulated degree-days (ADD) was used to estimate the variations based on the mean and standard deviation of the temperature measurements. It was found that there was a negative correlation between the base temperature of the fly species (lowest temperature at which the flies will survive) and developmental likelihood. Species with high base temperatures (Chrysomya albiceps, Chrysomya chloropyga, and Musca domestica) were less likely to continue development in refrigerators than species with lower base temperatures (Lucilia sericata and Piophila casei). The findings of this study highlight the importance of recording temperature measurements and the period of refrigeration on PMI estimation especially when continued development occurs in spite of a period of cooling of the insect evidence.
