Four systemic insecticides, disulfoton, dicrotophos, monocrotophos, and aldicarb were evaluated for their effect on the longevity and fecundity of Anthonomus grandis Boheman. Weevils were exposed continuously to 2 treated substrates: (1) filter paper treated with the toxicants, and (2) excised cotton leaves that had taken up known amounts of the toxicants through the petioles, Mortality increased with time and increased doses, Also, the rate of oviposition decreased during a 19-day period when the weevils were continuously exposed to sublethal doses of the insecticides; greater reductions occurred at higher doses. In all tests, aldicarb affected mortality and fecundity more than other insecticides.
