Varietal differences in the susceptibility of cowpea to larvae of the seed moth, Cydia ptychora (Meyrick) (Lepidoptera: Tortricidae)



Varietal differences in the susceptibility of cowpea to larvae of the seed moth, Cydia ptychora (Meyrick) (Lepidoptera: Tortricidae)



Bulletin of Entomological Research 681: 47-56



Glasshouse and field screening showed that several varieties of cowpea (Vigna unguiculata) in the germplasm collection at the International Institute of Tropical Agriculture at Ibadan, Nigeria, had promising levels of resistance to damage by larvae of Cydia ptychora (Meyr.). There was no preference between varieties for oviposition in the glasshouse, but varietal differences in damage to pods and seeds occurred due to differences in the pod-boring and seed-feeding success of larvae.
