Widespread distribution. A pest of food and field legumes, especially cowpeas, and other Vigna species. Minor pest.
Adults and nymphs suck pods causing pitting and shrivelling of seeds. Also, damage flowers and buds.
Adults are 10-12 mm long, dull brown, narrow, almost parallel-sided, with cream stripe along the side, and prominent eyes. Nymphs are ant-like.
Cultural control: plant far from already infested crops; handpick bugs where plots are small; destroy remains of plants after harvest.
Chemical control: PDPs, e.g., derris, pyrethrum or chilli. If commercial products needed, use synthetic pyrethroids or malathion. Use products recommended against green vegetable bug (see Fact Sheet no. 98).
