Behaviour of the Cowpea Pod Borer, Marruca testulalis Geyer


USUA, E. J. and SINGH, S. R

Abstract: The adult moths and the larvae of the cowpea pod borer Marruca testulalis Gey are noctural. The larvae emerge early in the evening and remain on the plant throughout the night. Studies of the behaviour of the larvae showed that they are photonegative and more inclined to attack bunched cowpea pods. It is suggested that in cowpea breeding, emphasis should be placed on producing plants having long peduncles carrying fruit pods well above the foliage.
