The field efficacy of the insecticide chlorpyrifos + cvpermethrin (500 + 50 g a.i./L) (Nurelle - D 505 EC) against cocoa pod borer (CPB) was studied. The results showed that the insecticide is effective in controlling CPB at 0.36 L/ha (chlorpyrifos + cvpermethrin: 180 + 18 g a.i/ha) .This provided equal control as the standard deltamethrin at 1.0 I/ha. Six rounds of spraying significantly reduced the mean number of eggs and percentage of pod infestation by the CPB. Chlorpyrifos + cypermethrin was effective in controlling egg population to about 8 weeks after the final spray.
