Abamectin in sugar-yeast hydrolysate bait was tested on colony-reared
adult Caribbean fruit flies, Anastrepha suspensa (Loew), in the labora
tory in a no-choice design. The EC(99)s (irreversible knockdown follow
ed rapidly by death) for sexually mature females and males were 12.2 a
nd 19.6 ppm, respectively, at 48 h. Abamectin is a promising alternati
ve to malathion in bait control programs in Florida citrus production.
