摘要
为了有效防治蛀干害虫小线角木蠹蛾,本研究采用皮透与13种农药分别组配,利用树干喷雾法,筛选防治小线角木蠹蛾的最佳组配剂.结果表明,防治当年孵化的小幼虫,皮透与15%氯氟·吡虫啉悬浮剂(SC)配比为2∶1的100倍液,防治效果达到95.94%;防治跨年度的大幼虫,皮透与15%氯氟·吡虫啉SC配比为2∶1的30倍液,防治效果可达到90.13%.结果发现采用皮透与15%氯氟·吡虫啉SC配比为2∶1的30倍液能够有效控制小线角木蠹蛾的危害.本研究为小线角木蠹蛾等蛀干害虫的防治提供了科学的依据,探索出了新的防治途径.
In order to effectively control Holcocerus insularis, 13 kinds of commercial pesticides were combined with ‘Pitou’ in this study and applied by tree trunk spray method to screen the best combination of control agents for the moth.The results of experiments showed that the 100×dilution of ‘Pitou’ and 15% chlorfluorinated imidacloprid suspension concentrate(SC) in a ratio of 2∶1 had control efficiency of 95.94% for the larvae hatched in current year. The results of experiments with cross-year larvae showed that the 30× dilution of ‘Pitou’ and 15% chlorfluorinated imidacloprid SC with ratio of 2∶1 achieved 90.13% of control efficiency. In conclusion, the 30× dilution of combined pesticides can be used to effectivelycontrol the Holcocerus insularis.
