ABSTRACT
The quality and marketing of horticultural crops is affected by the feeding of thrips on plant tissues. Thrips commonly feed upon the gladiolus and different vegetative and floral parts of gladioli are attacked by them. Application of chemical insecticides provides effective control of insect pest in short period of time. The present investigation was carried out on Jasminum sambac against flower thrips for efficacy of insecticides. To conduct this experiment, six insecticides viz., imidacloprid 20Sl, Spinosad 240SC, Spintoram 120SC, Chlophenapyre, Imidacloprid+fipronil and abamectin were applied. Thrips population was observed on jasmine flower before application of insecticides and thrips mortality data was noted after 24, 72 and 168 hours of insecticides spray. The maximum mortality of thrips was recorded in Imidacloprid+fipronil (68.45%) and Spinosad (65.45%) after 24 hours of insecticides spray. The lowest mortality of thrips was counted in abamectin and imidacloprid. Population of thrips was reduced after 72 and 168 hours as compared to 24 hours after insecticides spray. It is concluded from the findings of investigation that the insecticide (Imidacloprid+fipronil) was found effective against the population of thrips after 24, 72 and 168 hours in years, 2021 and 2022, respectively when compared to other insecticides.
