Spodoptera frugiperda (J E Smith) (fall armyworm) (Lepidoptera: Noctuidae), is a key pest of maize that has recently entered in India causing damage and yield loss. A biocontrol-based integrated pest management (IPM) strategy was designed and evaluated in farmer’s field during rabi and kharif season (2018–2019). IPM strategy comprising installation of controlled release FAW pheromone traps, four releases of Trichogramma pretiosum Riley, two sprays of neem oil, one spray of each Bacillus thuringiensis (NBAIR-BT25) and Metarizium anisopliae (NBAIR Ma-35) resulted in 76 and 71.64% egg mass; 80 and 74.44% larval population reduction at 60 days after treatment during rabi and kharif season, respectively. Cob yield per acre in biocontrol-based IPM field was higher than the farmer’s practice (6–7 sprays of emamectin benzoate 5% SG) during both the seasons, and it resulted in 38.3 and 42.29% gain in yield per acre during rabi and kharif, respectively. Therefore, this module forms a base to manage the fall armyworm in an eco-friendly and farmer friendly manner. Future research with other alternatives has also been discussed.

基于生物防治的秋玉米夜蛾对印度玉米的危害(JE Smith)(鳞翅目:夜蛾科)

夜蛾Spodoptera frugiperda,JE Smith)(秋夜蛾)(鳞翅目:夜蛾科)是玉米的一种主要害虫,最近进入印度,造成损害和产量损失。在狂犬病和卡里夫季节(2018-2019年)期间,在农民田间设计并评估了一种基于生物防治的病虫害综合防治策略。IPM策略包括安装控制释放的一汽信息素诱捕器,四个释放的眼衣原体Riley,两次喷入印em油,每株苏云金芽孢杆菌(NBAIR-BT25)和Metarizium anisopliae(NBAIR Ma-35)产生了76%和71.64%的鸡蛋质量;在狂犬病和kharif季节治疗后第60天,幼虫数量减少了80%和74.44%。在两个季节中,基于生物防治的IPM田的每英亩玉米芯产量均高于农民的实践(喷洒6-7代氨氧化菌素苯甲酸酯5%SG),在狂犬病和卡里夫期间每英亩的产量分别增加了38.3和42.29% , 分别。因此,该模块构成了以生态友好和农民友好的方式管理秋季粘虫的基础。还讨论了其他替代方法的未来研究。
