Detailed explanation-1: -Accumulated degree hours (ADH) are the number of hours at an adjusted average temperature it takes for an insect species to develop to a given developmental stage. ADH are used to estimate postmortem intervals.
Detailed explanation-2: -The ADH was calculated for L. sericata life cycle in both cases by using the following formula: ADH=Time (Hrs.) ×(Average temperature-Minimum development threshold temperature) and the reference developmental durations for L.
Detailed explanation-3: -Forensic entomologists identify insects from the crime scene, using accumulated degree hours (ADH) to estimate an approximate time of death. The ADH information allows forensic entomologists to estimate the time involved in developing the current stages of insect succession, in accordance with local conditions.
Detailed explanation-4: -Accumulated degree days are the continuous addition of consecutive degree days from a set starting point.
Detailed explanation-5: -A true fly in the family Calliphoridae and the most common insect observed and studied with cadavers in the field of forensic entomology. The blowfly life cycle consists of six stages: egg, three larvae stages, pupa, and adult.
