TAILIEUCHUNG - Bioassay studies for testing toxicity of novel insecticides against Spodoptera litura (Fabricius.)

Bioassay studies were conducted in the Department of Entomology, College of Agriculture, Rajendranagar, Hyderabad to determine the relative toxicity of selected novel insecticides viz., chlorfluazuron, chlorantraniliprole, spinetoram, indoxacarb, emamectin benzoate and spinosad against second instar larvae ofS. Litura by topical application, residue method and surface diet method. The data on the toxicity of insecticides to S. litura, clearly indicated that among the six insecticides tested against the second instar, emamectin benzoate, spinetoram, indoxacarb, chlorfluazuron, chlorantraniliprole showed greater toxicity against S. litura compared to spinosad in all the three methods of application. | 2020 9 7 1609-1613 International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 9 Number 7 2020 Journal homepage http Original Research Article https Bioassay Studies for Testing Toxicity of Novel Insecticides against Spodoptera litura Fabricius.

Introduction conditions. Also such baseline data would provide a record for detecting resistance level Bioassay is defined as the measurement of of the insect pests to various insecticides at the potency of any stimulus which may be different periods. physical chemical biological physiological or psychological etc. by means of the The tobacco caterpillar Spodopteralitura reactions which it produce in the living Fabricius Lepidoptera Noctuidae is also organism Finney 1952 . Bioassay helps in an important polyphagous pest infesting ascertaining the potency and relative toxicity crops of major economic importance. It was of .
