Abstract:
At present, the main tool for controlling insect pests are broad-spectrum neurotoxic insecticides. These chemicals have a number of serious drawbacks including their toxicity to mammals including humans and non-target organisms as well as their persistence in the environment. Another major problem associated with their utilization is the possible development by the insects of genetically-based resistance to insecticides which may lead to unexpected control failures. Therefore, the development of novel biorational, specific and non-toxic approaches to pest control is highly desirable. The term biorational is derived from two words, biological and rational, referring to pesticides of natural origin that have limited or no adverse effects on the environment or beneficial organisms. Biorationals also called as selective pesticides or reduced risk pesticides or green chemistry pesticides.
