Abstract
Studies of populations in field over five-year period, 1967–72, showed Heliothis zea (Boddie) to be the principal insect pest on the ears of sweet corn in south Florida. Spodoptera frugiperda (J. E. Smith) also was regularly present, and in certain seasons it was the dominant species. Evaluations of chemical and biological insecticides for control of these insects were made fall spring 1917-72 as a continuation of work previously reported. Among several insecticides tested, Dipel® (Bacillus thuringiensis Berliner) + corn oil, leptophos, methomyl, monocrotophos, and acephate gave 95 percent or higher injury-free sweet corn ears when applied at 2- to 3-day intervals against predominantly S. frugiperda. Malathion also was effective but at high application rate.
