Efficacy of insecticide applications at different times of day against the legume pod-borer, Maruca testulalis (Geyer) (Lepidoptera: Pyralidae), on cowpea in Nigeria.

Decamethrin and endosulfan are highly effective against the pod-borer and show little interaction with time of spraying. For monocrotophos, however, which gives poor control of the borer during high infestations, time of insecticide application appears to be important. -from Author
