abstract
Generating the baseline toxicity data for any insecticide is an important requirement for insecticide resistance monitoring. It also provides guide for formulating resistance management strategies in Integrated Pest Management. The present study on “Establishment of baseline toxicity data to thiamethoxam for adult black legume aphid, Aphis craccivora Koch. by leaf dip bioassay” was carried out at the Insecticide Toxicology Laboratory, Department of Entomology, College of Agriculture, OUAT, Bhubaneswar, Odisha during 2017-2018. The LC₅₀ for the susceptible strain was found to be 2.62 ppm with fiducial limits of 1.91 – 3.43 ppm and the LC₉₅ was found to be 27.73 ppm with fiducial limits of 16.77 – 63.72 ppm. Other findings and supporting reports are discussed.
