摘　　要：为研究适用于广西石山地区草地贪夜蛾的有效防控策略,在广西大化县开展了田间草地贪夜蛾发生动态监测和对靶施药防控试验。2021-2022年草地贪夜蛾性诱监测结果显示,该地区每年4月上旬、7月上中旬及11月中下旬出现明显蛾峰,其中11月中下旬诱集蛾量最大。2022年对靶施药防控试验结果表明,采用苏云金杆菌G033A与氯虫·甲维盐颗粒剂的混合配方在受害植株及其邻近植株处局部撒施,防治效果在70%以上。相比传统的全覆盖式撒施,该方法防治效果无显著差异,但能显著减少农药的使用量,实现省工且高效的防控目标。研究成果为广西石山地区针对玉米草地贪夜蛾的有效防控提供了科学依据和实践指导。This study aimed to develop an effective control strategy for Spodoptera frugiperda in the Karst area of Guangxi.Field monitoring of the occurrence dynamics of S.frugiperda and the target pesticide application control experiments were carried out in Dahua County,Guangxi.The pheromone attractant monitoring data from 2021 to 2022 showed distinct moth peaks in early April,early to mid-July,and mid to late November each year in this area.The highest number of moths were trapped during mid to late November period,indicating the most severe infestation phase.The targeted application control test conducted in 2022 revealed that the mixed formulation of Bacillus thuringiensis G033A and chlorantraniliprole'emamectin benzoate granules,when applied locally to infested plants and adjacent plants,achieved a control effect of over 70%.This targeted method showed no significant difference in control effect compared to traditional fullcoverage spraying,but significantly reduced pesticide usage,achieving labor-saving and highly efficient control goals.The research findings offer an important scientific foundation and practical guidance for developing effective prevention and control strategies for the fall armyworm in corn in the Karst area of Guangxi.
