HORTICULTURE

Detailed explanation-1: -Their development follows a set, predictable, cycle. The insect egg is laid in batches on the corpse and hatches, after a set period of time, into a first instar (or stage) larva. The larva feeds on the corpse and moults into a second instar larva. The larva continues to feed and develop into a third instar larva.

Detailed explanation-2: -Because flies rapidly discover a body and their development times are predictable under particular environmental conditions, the time of death can be calculated by counting back the days from the state of development of flies living on the corpse.

Detailed explanation-3: -The larvae of flies (maggots) are the most obvious and abundant fauna present on corpses in the early stages of decomposition. House flies Muscidae and blowflies Calliphoridae are the first to arrive (pioneer flies). Flies in both these families lay eggs (although some blowflies ‘lay’ larvae).

Detailed explanation-4: -Forensic Entomology is the use of insects and other arthropods that feed on decaying remains to aid legal investigations. Time of Death (TOD). 1) Identification of insects at various stages of their life cycle. 2) Collection and preservation of insects as evidence.
