Case report on Cochliomyia hominivorax (Coquerel, 1858) and Co. macellaria (Fabricius, 1775) (Calliphoridae, Diptera) myiasis prior to death: Implications on postmortem interval estimation.

The most important contribution of forensic entomology is the estimation of the postmortem interval (PMI) or time since death. The forensic entomologist assumes that the biological clock of necrophagous insects that develop by feeding on cadaver tissues begins when the victim's biological clock is turned off. However, tissues can be invaded while the host is still alive (called myiasis), so the period of activity of necrophagous insects would not be indicative of PMI.

Influence of diesel fuel contamination on L. germination and growth.

In this study, the effects of diesel fuel contamination on common cocklebur ( L.) seeds have been investigated. Five levels of contamination were used (0 g, 2.
