Summary

Insect infestation and damage in cowpea (Vigna unguiculala), planted sole or intercropped with tomato (Lycopersicon esculentum) was monitored in 1987 and 1988 in Akure, Nigeria. Infestation of cowpea by Empoasca dolichi was significantly reduced by intercropping with tomato in both years, except in the early season of 1988. Infestation of cowpea by Ootheca mutabilis, Aphis craccivora, Megalurothrips sjosledti and Maruca testulalis was not affected by intercropping with tomato in either year. Damage by pod-sucking bugs and Heliothis armigera was significantly higher in sole cowpea than in cowpea intercropped with tomato, in both years. Sole cowpea had a significantly lower seed yield than cowpea intercropped with tomato.
