Abstract

Abstract Pulse beetle, Callosobruchus spp. are the major threat in legume grain (pulse) storage. They are very prolific and rapid in breeding and increasing their population within short period of time. Its infestation starts either in the field on the maturing pod and is carried to the stores with the harvested crops or it originates in the storage itself. If appropriate management is not adopted, then it can damage 100% of stored pulses within few months of storage. On an average they cause 5–10% pulse crop losses in the temperate and 20–30% in the tropical countries during storage. Here this article is intended to discuss their distribution, host plants, life cycle, damage symptoms, ecology, economic impact and their management by recent and effective techniques.
