Abstract: The legum e pod borer, M aruca (testulalis) vitrata (Geyer) is one o f the m ajor lim itations to increasing the production and productivity of grain legum es in the tropics. Bionom ics, host-plant resistance, natural enem ies, cultural practices, and chem ical control of the legum e pod borer have been d is cussed in this bulletin to identify gaps in present know ledge and to help plan future strategies for research on this pest on pigeonpea. W hile inform ation is available on bionom ics and host-plant resistance in cow pea, such inform ation on pigeonpea and other legum es is lim ited. Several natural enem ies have been recorded on M. vitrata, and pathogens such as Bacillus thuringiensis, Nosema, and Aspergillus play an im portant role in regulating its populations under field conditions. Cultural practices such as intercropping, tim e of sow ing, density of sow ing, and w eeding reduce the pod borer damage. Several insecticides have been found to be effective for controlling this insect. There is a need to focus future research on standardizing the resistance screening techniques, identifica tion and utilization of resistance, and integrated pest m anagem ent strategies for sustainable agricultural production.
