Type: article
Abstract: Present investigation revealed that three species of insect-pests viz. white fly (Bemisia tabaci), jassid (Empoasca kerri) and thrips (Caliothrips indicus) were found as major insect-pests of mungbean on the basis of their population build up and severity of infestation. White fly, jassid and thrips attacked the mungbean from seedling to maturity stage. Among the microbial and chemical insecticides combination of seed treatment with Pseudomonas florescens + Beauveria bassiana (spraying) gave better response and was found most effective against white fly followed by seed treatment with Pseudomonas florescens. Similarly in case of jassid, the seed treatment with imidacloprid gave better result followed by combination of seed treatment with Beauveria bassiana + Pseudomonas florescens. In case of thrips, combination of seed treatment with Beauveria bassiana gave best performance with lowest thrips infestation and highest reduction over control, followed by the seed treatment with imidacloprid. All the insecticides found to be effective in increasing the yield over control. The highest yield (6.98) q ha-1 was recorded in combination of seed treatment with Beauveria bassiana and spray with profenophos followed by combination of seed treatment with Pseudomonas florescens + spray with B. bassiana (6.42 q ha-1).
