Suppression of Rice Stem Borer, Chilo suppressalis by Mass Trapping Using Synthetic Sex Pheromone in Paddy Field

Suppressing effects of mass trapping using synthetic sex pheromone with main active ingredients of Z-11-hexadece-nal, Z-13-octadecenal and Z-9-hexadecenal on the rice stem borer, Chilo suppressalis were investigated during the flight periods of the overwintering and 1^st generation in the paddy area of 60 ha in 1999. Population density of C. suppressalis in the pheromone-treated fields was lower than that in control. The egg masses decreased by 74. 39% and population size of adult males of the 1^st generation decreased by 61.64% in the treated fields as compared to control. Meanwhile, the damage by C.suppressalis larvae was significantly lower in the treated fields than control (t-test, P=0.05). Percentages of brownish leaf sheath, dead heart, and white head in the treated fields were decreased by 70.90%, 57.01% and 44.30%, respectively in contrast to control. The present study demonstrated that mass trapping to C. suppressalis using synthetic sex pheromone shows great potential as an alternative measure in an environment-friendly pest management and at the same challenging the insecticide use that has some environment impacts.     

安溪县金谷镇松墨天牛发生量的研究

为了更科学地开展金谷镇松墨天牛的防治工作,对泉州市安溪县金谷镇2019～2020年每月气温变化及林间松墨天牛诱捕数量进行了分析.结果表明:金谷镇松墨天牛诱捕量的年变化与气温变化趋势相同,呈现先增加后减少的趋势,每年5月份为松墨天牛的诱捕高峰.金谷镇可根据夏季林间气温的大小和持续时间,有效预测该年度夏季松墨天牛诱捕量和次...     

食物诱剂和粘胶型球形诱捕器协同防治柑橘大实蝇 效果调查

食物诱剂诱杀成虫是目前防治柑橘大实蝇的最主要措施,但是效果受施药期间的天气制约,周边山林多的橘园防治效果不稳定,5月下旬加挂诱蝇球,能够弥补其不足,提高防治效果。示范区加挂诱蝇球后,大实蝇虫果率显著下降,基本上达到防治标准。

针对蔬菜害虫"三贪"习性采取"五诱"技术进行诱杀

“三贪”（贪色、贪玩、贪吃）是蔬菜害虫特有的习性，针对害虫的“三贪”习性，可采取“五诱”技术（性费洛蒙、色板、灯光、糖醋液、杨树枝把）进行诱捕成虫，将害虫的雄蛾消灭在交尾之前，使雌蛾失去交尾机会而导致其后代“胎死腹中”。
