title: Toxicity of nicotine derivatives and their effect on the protein pattern of 4th immature stage of red cotton stainer Dysdercus koenigii (Fabr) (Hemiptera: Pyrrochoridae).
abstract: Toxicity of Nicotine dust and Nicrotine cyanurate was observed against the 4th immature stage of Dysdercus koenigii (Fabr.) by injection method. Mortality rates were noted after 24 hours of treatments. LD50's were calculated as 7.2 microg/nymph and 9 microg/nymph for nicotine dust and nicotine cyanurate respectively. Changes in the flow of protein metabolites occur with higher and lower doses of both the compounds.
