Abstract

A field experiment with 51 yard-long bean cultivars revealed significant variation. in pod damage by legume pod borer among the cultivars. There was significant negative correlation between density of non-glandular trichomes on pod wall and severity of pod damage. The correlations of pod width with pod infestation and pod damage severity were positive and significant. It is concluded that high density of non-glandular trichomes on pods and low pod width tend to reduce the attack of yard-long bean pods by legume. pod borer.

Keywords: Yard-long bean, Legume pod borer, Pod damage
