Management of melon thrips, thrips palmi karny (thysanoptera: thripidae) using various chemicals

Dakshina R. Seal


The melon thrips, Thrips palmi Karny, is a significant pest of vegetable crops in south Florida. Four studies were conducted to determine the effectiveness of insecticides in controlling the melon thrips on vegetable crops in south Florida. Fenpropathrin (Danitol®) alone at 21 oz/acre, or fenpropathrin in combination with acephate (Orthene®) and pyriproxyfen (Knack®) strongly suppressed T. palmi populations. Emamectin benzoate (Proclaim®) at various rates significantly reduced T. palmi adults and larvae. Azadirachtin (Azadirect[tm] 1.2) at rates between 17.3-21.5 oz/acre provided significant control of T. palmi adults.
