摘　　要：为探索西藏林芝市小菜蛾绿色监测防控技术,在露地冬油菜田筛选诱集效果最佳小菜蛾性诱剂,利用诱集效果最佳性诱剂监测不同地块小菜蛾种群发生动态。在林芝巴宜区比较了3个品牌性诱剂诱集效果,发现中捷四方品牌性诱剂诱集效果最佳;利用中捷四方品牌性诱剂诱芯对不同地块小菜蛾进行监测显示,露地冬油菜地块小菜蛾成虫发生高峰期为7月上中旬,温室白菜地块小菜蛾成虫发生高峰期为5月上旬至5月下旬,露地前茬白菜田几乎诱集不到小菜蛾成虫,温室门口监测显示秋季有小菜蛾成虫迁移至温室内。通过对小菜蛾越冬虫态进行调查,显示露地上没有小菜蛾越冬,其越冬场所主要集中在条件较好的温室内,建议在林芝市巴宜区使用中捷四方品牌性诱剂监测小菜蛾危害的发生,露地和温室要有机结合起来进行监测。In order to explore the green monitoring and control technology of Plutella xylostella in Nyingchi region of Tibet,the best attractive effect of Plutella xylostella sex pheromone was selected in the open field of winter rapeseed,and the population dynamics of diamondback moth in different plots was monitored using the best attractive effect Plutella xylostella sex pheromone.The attractive effect of three brands were compared in Bayi town of Nyingchi,and the results showed that the attractive effect of Zhongjie Sifang brand was the best.Utilization of Zhongjie Sifang brand sex pheromone monitor in different plot showed that in the outdoor field of winter rapeseed,adults occurrence peak occured in the middle of July,and adults occurrence peak occurred in early to late May in greenhouse vegetable plot.However,there were almost no adults trapped in open field,and monitoring at the entrance of the greenhouse showed that the adult Plutella xylostella migrated to the greenhouse in Autumn.The investigation of Plutella xylostella overwintering showed that there was no Plutella xylostella overwintering in the open field,and the overwintering place was mainly concentrated in the greenhouse with better conditions.It is suggested to use Zhongjie Sifang brand sex sex pheromone to monitor occurrence and damage of Plutella xylostella in Bayi town of Nyingchi.The open field and greenhouse field should be effectively combined for monitoring.
