Pigeonpea (Cajanus cajan) is an important crop in semi-arid tropical and subtropical farming systems, providing high quality vegetable protein, animal feed,
and firewood. Insect pests feeding on flowers, pods, and seeds are the most important biotic constraint affecting pigeonpea yields. This review summarizes the
biology and ecology of the three most important groups of pests: flower- and
pod-feeding Lepidoptera, pod-sucking Hemiptera, and seed-feeding Diptera and
Hymenoptera. Recent research investigating the complex interactions among
pigeonpea, its key pests, and their natural enemies is also reviewed. These relationships have implications on the pest status of individual species and on possible
control strategies. Pigeonpea pest management research has focused until recently
on the identification and development of resistant cultivars and on chemical control. Future research must focus on environmentally sound pest management
strategies that are compatible with the needs and limitations of pigeonpea farmers. Several priority areas for research are suggested.
