Abstract

Green gram (Vigna radiata L.) is an important short duration pulse crop widely cultivated across South and Southeast Asia for its nutritional value, contribution to soil fertility and role in smallholder livelihoods. However, its productivity is severely constrained by a complex of sucking pests including aphids (Aphis craccivora), jassids (Empoasca spp.), whiteflies (Bemisia tabaci), thrips (Thrips spp.) and spider mites (Tetranychus spp.). These pests cause yield losses through direct sap feeding and indirectly by transmitting viral diseases, particularly yellow vein mosaic disease, often leading to serious economic damage. Prolonged dependence on chemical insecticides has resulted in resistance development, pest resurgence and negative impacts on natural enemies and the environment. This review summarized recent developments in the sustainable management of the main green gram sucking insect pests, with a focus on integrated pest management strategies that incorporate host plant resistance, biological control and natural enemy conservation, behavioural and ecological engineering techniques, the use of botanical and microbial biopesticides, selective application of reduced risk insecticides guided by economic threshold levels and cultural and agronomic practices. In order to increase productivity while maintaining the sustainability of the environment and human health, the analysis also highlighted future opportunities such as climate smart Integrated Pest Management (IPM), landscape-level biological management and breeding for lasting resistance. Keywords: Aphid, Biocontrol, Sustainable management, Vigna radiata, Whitefly.
