2019年草地贪夜蛾灯诱监测应用效果

　　摘要 2019年草地貪夜蛾灯诱结果，广西、湖南、湖北、河南、陕西、山西、宁夏、天津8省（区、市）14个高空测报灯观测点，6月始灯下陆续见蛾，8月-10月多数观测点出现明显蛾峰;湖北、河南、天津3省（市）8个常规测报灯观测点7月-10月灯下见蛾，9月下旬和10月上旬出现蛾峰。因此，高空测报灯可用于草地贪夜蛾区域性种群动态监测，种群超过一定数量条件下常规测报灯有效，灯具需选择合适地点设置。多数高空测报灯下雄蛾量明显高于雌蛾量，常规测报灯雌雄比差异不大，其原因有待深入研究。

　　Abstract
　　In 2019， there were 14 searchlight-trap observation points were set in 8 provinces （autonomous regions and cities） including Guangxi， Hunan， Hubei， Henan， Shaanxi， Shanxi， Ningxia and Tianjin for monitoring the moth of Spodoptera frugiperda. From June， the moth was successively trapped by the searchlight-trap， and obvious moth peaks appeared during August to October in most of observation points. The moths were found under the light trap in 8 observation points in Hubei， Henan and Tianjin from July to October， and the peaks appeared in late September and early October. The results indicated that the searchlight-trap is suitable to monitor the regional population dynamics of S.frugiperda， and the light trap should be used when the population size is big enough. Two types of light trap need to be set at appropriate positions according to their characteristics. The number of trapped male moths was significantly higher than that of female under the most searchlight-trap， while it showed no significant difference under the light trap. The reason of these phenomena needs further study.
