ABSTRACT
During the study, different control practices, such as host plant resistance, imidacloprid seed treatment combined with the use of blue sticky traps, neem seed kernel extract, the entomopathogenic fungus Beauveria bassiana and synthetic insecticides (acephate and chlorfenapyr), were tested individually and in various combinations for managing thrips (Megalurothrips distalis). A mungbean genotype, 13TM-04, known for its comparative resistance, was chosen for these trials. The treatments, whether applied alone or in various combinations, showed significant differences in efficacy when compared with each other. A combination of treatments viz., imidacloprid seed treatment+ installation of blue sticky traps and chlorfenapyr 360 SC @ 100ml/acre spray was observed to be the most successful against thrips and resulted in maximum yield 1970.1 kg/ha of mungbean. While imidacloprid seed treatment with blue sticky trap installation, alone, did not show distinctive impact on the thrips population as well as on the yield in mungbean. The imidacloprid seeds treatment remained effective up to 38 days after sowing against the thrips. The application of chlorfenapyr and acephate, either individually as sprays or in combination with other control measures, resulted in a notable reduction in the thrips population. For the management of M. distalis in mungbean combination of imidacloprid seed treatment, blue sticky traps installation and chlorfenapyr at 100 ml/acre should be applied. Current studies provide useful information to adopt integrated pest management of thrips at Bhakkar district for the local farmers for better crop yield.
