The incidence of thrips was studied at Horticulture Farm, S.K.N. College of Agriculture, Jobner (Rajasthan) on garlic crop during Rabi season. The incidence of thrips on garlic crops was commenced in the first week of February and reached its peak in the second week of March. The predator, Coccinella septumpunctata Linn. was commenced in the second week of February and reached the maximum in the second week of March. The weather parameters viz., temperature, relative humidity, and sunshine (hrs) had a non-significant correlation with thrips incidence on garlic crop, whereas, predator, C. septumpunctata possess significant positive correlation.
Keywords: Incidence, Garlic, Thrips tabaci, Coccinella septumpunctata.
