Studies on pod infesting insect pest complex of pigeonpea Cajanus cajan L. (Millsp.) and their control with insecticides and biopesticides: A review
Author(s): Sagar Anand Pandey
Abstract: Pigeonpea (Cajanus cajan (L) Millsp.) is one of the most important pulse crops grown worldwide because it is endowed with several unique characteristics with diversified uses for human needs and is an important crop in semiarid tropical and subtropical areas. Especially in Asia it is a major source of protein for humans. As many as 250 insect species have been recorded to attack pigeon pea among which the pod-borers and pod fly are the most damaging pests, inflicting considerable damage to the reproductive parts of the plant. The pigeon pea pod fly Melanagromyza obtusa Malloch (Diptera: Agromyzidae) is found throughout south and central Asia. The main country suffering from its pestilence is India because of widespread pigeonpea cultivation (>90% of the world production). Females deposit eggs on the pigeon pea green pods and the developing larva initially feeds just under the epidermis of the seed like a leaf miner. Generally, pod yield losses due to this vary between 5-30 per cent during winter and spring from several countries Hence, attempts were made to evaluate the efficacy of different insecticides and botanicals for the sustainable management of the pigeon pea pod fly.
