Abstract: Bulb crops are best suited as a tropical crop. Onion is popularly called as “Queen of Kitchen” as it is used as food, salad, spice, condiment and in medicine. Garlic is used as a spice. It is important because of its medicinal properties. Extract of garlic acts as fungicidal, bactericidal and insecticidal action. Full yield potential of the crop is not realized due to the number of constraints. Among them, pest and diseases are the major constraints in bulb crop production. Pest management is crucial for obtaining good quality marketable bulb. Arthropod pests and diseases that can reduce crop yield both in terms of quantity and quality. Major insect pests of bulb crops are onion thrips, reduce the yield potential. Management of bulb crops pests relies on insecticide use during crop growing period, but insecticide resistance can cause control failures that threaten the long-term viability of this strategy. IPM strategies minimize the losses and increase the marketable value of bulb crops. Infestation of onion thrips was started from the first week of February and it became gradually increased upto the first week of April and thereafter it was declined. Cultural practices such as intercropping, mixed cropping, time of planting, spacing, mulching, fertilizer doses, irrigation scheduling and blue colored traps are more effective. Bbiopesticide, botanical and some chemicals are also a very important components of the eco-friendly management of onion thrips of bulb crops
