Abstract: Cyromazine and abamectin were the most efficacious insecticides against Liriomyza trifolii (Burgess) on potted- and cut-chrysanthemums. Oxamyl, oxamyl plus methomyl (tank-mix),and permethrin plus microencapsulated methyl parathion (tank-mix) were also effective against L.trifolii No adverse effects of tested insecticides to the leafminer parasitoids, Diglyphus intermedius (Girault) and Ganaspidium hunteri (Crawford) were observed. Results emphasized that permethrin and microencapsulated methyl parathion were effective in a tank-mix, but not when used separately. The ineffectiveness of permethrin or microencapsulated methyl parathion alone may be indicative of L trifolii developing resistance to these insecticides.
