Observations on Pod Borer Oviposition and Infestation of Pigeonpea Varieties

Abstract

Thirteen varieties of pigeonpea (Cajanus cajan (L.) Millsp.) were planted to determine pod borer oviposition preferences and infestation percentages. Etiella zinckenella and Heliothis virescens were the predominant species. Oviposition of Heliothis began on flower buds but pods were preferred where available except for varieties Florido, Trinidad 5690 and Trinidad 6222 where a similar preference for bud and pods was recorded. Variety Guamá particularly was less attractive for oviposition. Varieties Saragateado, Florido and Totiempo showed highest infestation rates throughout the season.
