Abstract

The use of insecticides to decrease Thrips tabaci and Liriomyza trifolii population in onion (Allium cepa L.) was evaluated for two consecutive years.The insecticides most frequently used by farmers were evaluated: cypermethrin, avermectin, oxamyl, azadirachtin and dimetyl. A treatment with water only, plus the control, was also evaluated. It was observed that the use of cypermethrin resulted in the least number of nymphs and adults of Thrips tabaci and the best onion yield. As for Liriomyza trifolii, it was observed that the use of avermectin and cypermecthrin resulted in the least numbers of larvae.
