Abstract:
Thrips (Thrips tabaci Lindeman) is a major pest of onion and cause considerable losses in yield. The nymph and adult of thrips feed leaves by piercing and rasping the leaf tissues and causes lengthwise, silvery stippling or blotching on the onion leaves, resulting in the loss of chlorophyll and reduced photosynthetic efficiency. Thrips attack onion at all the stages of crop growth but their count increases from bulb initiation and remain high up to bulb development and maturity. Onion thrips can also transmit several plant pathogens in onion crop that reduced onion bulb size and quality. Therefore, the objective of this review was undertaken to evaluate previous work on the management of onion thrips.
