Mass rearing of potato tuber moths was conducted in a biocontrol laboratory to seek out appropriate management for the pest. The larvicidal efficacy of insecticides was studied by using four insecticides Bojho, Emamectine benzoate, Spinosad, Neem. The study discovered the effectiveness of all the insecticides, however the three pesticides had higher efficacy compare to Neem. The overall result indicates the highest mortality rate in treatments Bojho (100%), Emamectine benzoate (100%), and Spinosad (100%) whereas the lowest mortality rate in treatment Neem (94%). The infestation was conjointly high in Neem compare to the other three pesticides. To examine the efficacy of pesticides against PTM the applied treatments Bojho, Emamectine benzoate, and Spinosad was found to be the best insecticide among the trials in bringing down the PTM population as Neem showed to be less effective out of the total four pesticides applied. All the pesticides were effective in reducing insect population under laboratory conditions; however, their effectiveness was directly proportional to concentration and exposure periods. The study has demonstrated the possibility of using novel compounds in the IPM program.
