Laboratory bioassay methods to assess the insecticide toxicity against insect pests-A review

Abstract

Laboratory bioassays have become increasingly important because of their predictive value, generating comparative toxicity data on many chemicals in relatively short times at relatively low expense. The laboratory investigations provide a better understanding of insect-insecticide or insect-plant-insecticide interactions. It is a simple, versatile, easy and sensitive technique for determining toxicity of wide range of chemicals, which greatly facilitates the determination of the LD50, LC50 or any other lethal concentration/dose. The objective of present reviews is to know the different laboratory bioassay techniques for evaluation of different insecticide against insect pests.
