  "abstract": "<p><span lang=\"TR\">Rice, a staple food crop cultivated globally, sustains the livelihoods of millions of people. However, its productivity is significantly compromised by the infestation of various insect pests including green leafhopper (</span><em>Nephotettix virescens</em>)<span lang=\"TR\">. The overreliance on chemical insecticides has resulted in the development of resistance in green leafhopper, increasing the challenges for its effective management. So, this study aims to investigate the integration of microbial agents with chemical insecticides as a sustainable approach for the management of&nbsp;</span><em>N. virescens</em><span lang=\"TR\">.&nbsp;</span>Both individual and combined applications of the entomopathogen&nbsp;<em>Metarhizium anisopliae</em>&nbsp;and chemical insecticides against&nbsp;<em>N. virescens</em>&nbsp;under laboratory and field conditions were assessed. Initially, effects of six insecticides (Pymetrozyne, Deltamethrin, Thiamethoxam, Acephate, Imidacloprid and Diafenthiuron) on the vegetative growth of&nbsp;<em>M. anisopliae</em>&nbsp;were tested. Out of these, three insecticides (Imidacloprid, Pymetrozyne, and Thiamethoxam) were found to be compatible with the fungus, promoting increased vegetative growth, and were selected for further evaluation. Bioassay study against adults of&nbsp;<em>N. virescens&nbsp;</em>revealed that the LC<sub>50</sub>&nbsp;and LC<sub>90&nbsp;</sub>values for the combined treatments were lower than those for the insecticides alone, indicating synergistic effects, except for thiamethoxam. Pooled results revealed that the combination of&nbsp;<em>M. anisopliae</em>&nbsp;and imidacloprid proved to be effective against&nbsp;<em>N. virescens</em>, with 63.68% and 67.06% mortality in the first and second sprays, respectively, compared with 56.23% and 60.44% with imidacloprid alone under field condition. Scanning electron microscopy confirmed that the highest degree of conidial attachment occurred in the softer intersegmental regions near the legs, whereas fewer conidia were found in the head. These results suggest that&nbsp;<em>M. anisopliae</em>&nbsp;can be safely administered in the integrated pest management programme without hampering its efficacy for the management of rice leaf hoppers.&nbsp;<span lang=\"TR\">Farmers and policymakers are encouraged to adopt integrated pest management strategies combining compatible microbial agents and insecticides to enhance sustainable management of green leafhoppers.</span></p>",
