HORTICULTURE

Detailed explanation-1: -On a decomposed body, the feeding larvae may have human tissue stored in their crops that can be analyzed to determine: whether the deceased was exposed to either toxic chemicals or recreational drugs. Blowflies, also known as carrion flies or bottle flies, include: blue bottles, green bottles, and bronze bottles.

Detailed explanation-2: -[2] These insect colonizers can be used to estimate the time of death i.e., time interval between death and corpse discovery, also called postmortem index (PMI), movement of the corpse, manner and cause of death and association of suspects at the death scene.

Detailed explanation-3: -Insects are drawn to the decomposing body right from the early stages, and can lay eggs in it. Forensic scientists may estimate the post-mortem index, any change in the location of the corpse as well as the cause of death by observing the insect population and the evolving larval stages.

Detailed explanation-4: -Larva 3, which is known as instar 3, move away from the body before they undergo the pre-pupa stage. In this case, it is necessary to collect larvae from around the body or in the immediate vicinity. This would ensure that no insect evidence is overlooked.

Detailed explanation-5: -Blow flies and flesh flies are the most useful crime scene insects for determining the postmortem interval, or time of death. Through laboratory studies, scientists have established the developmental rates of necrophagous species, based on constant temperatures in a laboratory environment.
