“…M. spiracularis has been featured in forensic cases in Malaysia indoors 17,18 but the current developmental data available are the pupae development. 29 At present, the distribution of this species includes Japan, Malaysia, Taiwan, 30 China 31 and New Zealand. 32 In this study, M. spiracularis and M. scalaris were found coexisting indoors, similar to the report from the Northeast China.…”

Scuttle flies (Diptera: Phoridae) are a diversified insect group of forensic importance. Their frequent presence on human corpses indoors and in concealed environments can be the sole indicators to estimate the minimum post mortem interval (PMI min ). However, bionomics of scuttle flies on decomposing animal carcasses are rarely documented indoors. The objective of this research is to observe and document the occurrence of scuttle flies on decomposing animal carcass placed inside a portable cabin maintained at room temperature (%25.0°C) in Bangi, Malaysia. This study was conducted in two rounds for a period of 40-day each and samplings were carried out in different intervals. Adult scuttle flies were aspirated directly from the carcass and preserved in 70% ethanol. Their larvae and pupae were reared until adult stage to facilitate identification. Megaselia scalaris (Loew), Megaselia spiracularis (Schmitz) and Dohrniphora cornuta (Bigot) were the scuttle flies found on the carcasses with M. scalaris being the earliest and dominant to colonize the body. This cosmopolitan species proved to be the best indicator to estimate PMI min indoor but in the increased presence of other fly species, it might be relegated to a secondary role. The scuttle flies were also found to coexist with other dipterans of forensic importance in an indoor environment, mainly Chrysomya megacephala (Fabricius) (Diptera: Calliphoridae). This information expands the knowledge on the bionomics of scuttle flies on decomposing animal remains indoors.

“…As compensation, sampling amount and constant temperatures amount were increased. Under consistent constant temperatures, the duration of the pupal stage of C. rufifacies is usually shorter than L. sericata [37] and other necrophagous species [35,36]. Therefore, a more thorough external examination by shortening the sampling intervals would be helpful to establish more pupal developmental stages and to differentiate the sequence of morphogenesis among the same existing developmental stages.…”

“…In the same year 2012, the pupal development stages of Calliphora vicina at 22 8C were studied by Brown [32]; the pupal development stages of Lucilia sericata at 25 8C were studied by Zajac and Amendt [33], and similar studies were conducted on Calliphora vomitoria and Chrysomya albiceps by Ergil [34]. Feng and Liu [35,36] focused on the key developmental process during the pupal morphogenesis of Megaselia spiracularis and Megaselia scalaris at multiple different constant temperatures. In 2014, Karabey and Sert [37] studied the stages and duration of the pupal stage of L. sericata at temperatures of 20, 25 and 30 8C, whereas Brown et al [20] developed a timeline of metamorphosis on development of the external morphology of C. vicinia, and with an observation that 23 external metamorphic developments were correlated to age in accumulated degree hours (ADH) after puparium removal [20].…”

“…This method requires a lot of time, therefore, leads to missing the best opportunity to solve a case. Reliable age estimations of forensically relevant pupae are necessary, especially when pupae represent the oldest specimens present at a crime scene or even the only source of entomological evidence available [35,36]. As a forensic potential species, the pupal morphogenesis of C. rufifacies at different constant temperatures may provide more accurate estimates of the min PMI.…”

Abstract:The present paper investigates the pupal development times of Lucilia sericata which were studied in the laboratory at six different constant temperatures (20, 22, 24, 26, 28 °C each ± 1 °C). Lower thresholds (t L ) for development were estimated from the linear regression of the developmental rates on each temperature. These data have made it possible to calculate the ADD (Accumulated Degree-Days) necessary for L. sericata to complete the larval stage and to achieve adult emergence. The minimal duration of development from oviposition to adult emergence was found to be inversely related to temperature. Additionally, six landmarks in pupal development are showed and for each of the landmarks the ADD value was calculated for every rearing temperature involved. These data assist in calculating the duration of the pupal stage based on morphological characteristics and would be of great value for future forensic entomological casework.
