EFICIÊNCIA AGRONÔMICA DE INSETICIDAS NO CONTROLE DO Thrips tabaci LIND., 1888 (THYSANOPTERA, THRIPIDAE) NA CULTURA DO ALHO

A trial was carried out in Goiânia, Goias, Brazil, to test the efficiency of insecticides in controlling onion thrips (Thrips tabaci) on garlic. The treatments applied were thiacloprid 480 SC; methiocarb 500 SC; imidacloprid 200 SC; betacyfluthrin 50 EC; thiametoxan 25 WG; chlorpiriphos 450 EC, plus an untreated check. The insecticides were sprayed three times at ten-day intervals. Data showed that thiacloprid, methiocarb, imidacloprid, betacyfluthrin and thiametoxan were efficient in controlling the T. tabaci up to 15 days after treatment application. Chlorpiriphos with the tested dosage did not control the T. tabaci efficiently. KEY-WORDS: Insecta; thrips; chemical control.
