Abstract
Abstract : The present investigation entitled “Assessment of insecticide resistance in major stored grain pest” was carried out at laboratory, Seed Entomology Research Unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during 2020-21. A laboratory experiment was carried out to assess the insecticide resistance levels of malathion and deltamethrin against different populations of target insects viz., Rhyzopertha dominica, Tribolium castaneum, Sitophilus oryzae, Callosobruchus maculatus and Callosobruchus analis collected from local godowns of Akola district during 2020-21.The results revealed that the Rhyzopertha dominica populations tested for insecticide resistance showed resistance factor/Resistance Ratio (RF/RR) of 21.08 and 37.35 folds resistance, Tribolium castaneum showed resistance factor/Resistance Ratio (RF/RR) of 8.20 and 56.5 folds resistance. Sitophilus oryzae showed resistance factor/Resistance Ratio (RF/RR) of 12.56 and 27.5 folds resistance. Callosobruchus maculatus showed resistance factor/Resistance Ratio (RF/RR) of 12.5 and 26.6 folds resistance and Callosobruchus analis showed resistance factor/Resistant Ratio (RF/RR) of 12.19 and 83.3 folds resistance when compared to the laboratory susceptible strains LC50 values supplied, against malathion and deltamethrin insecticides, respectively.
The present findings indicate that the godown collected strains were more resistant to malathion and deltamethrin as compared to susceptible strains LC50 values supplied.
Description
Description : The present investigation was carried out at laboratory, Seed Entomology Research Unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during 2020-21. The treatment comprised of insecticide Deltamethrin 2.8 EC, Malathion 50 EC, Control (water) which were executed in probit analysis software with four replications.
