The Legume Pod Borer, Maruca vitrata:Bionomics and Management uri icon

abstract

  • The legume pod borer, Maruca(testulalis) vitrata (Geyer) is one of the major limitations to increasing the production and productivity of grain legumes in the tropics. Bionomics, host-plant resistance, natural enemies, cultural practices, and chemical control of the legume pod borer have been discussed in this bulletin to identify gaps in present knowledge and to help plan future strategies for research on this pest on pigeonpea. While information is available on bionomics and host-plant resistance in cow pea, such information on pigeonpea and other legumes is limited. Several natural enemies have been recorded on M.vitrata,and pathogens such as Bacillus thuringiensis, Nosema, and Aspergillus play an important role in regulating its populations under field conditions. Cultural practices such as inter-cropping, time of sowing, density of sowing, and weeding 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, identification and utilization of resistance, and integrated pest management strategies for sustainable agricultural production
