草地贪夜蛾首次入侵广东地区发生为害调查
|
摘要
草地贪夜蛾Spodoptera furgiperda(J.E.Smith)是一种新的重要农业入侵害虫,目前已侵入我国云南、广西、广东等地。本研究调查了草地贪夜蛾首次入侵成虫后代幼虫在珠三角和粤北地区的种群密度和为害情况。结果表明:本次调查珠三角和粤北地区均已出现草地贪夜蛾取食为害,所调查的10种作物中,仅在玉米上发现取食为害;其中草地贪夜蛾幼虫在从化地区为害最重(虫口数量222头/百株、为害率80%),其次是连平(虫口数量98头/百株、为害率68%)、英德(虫口数量76头/百株、为害率62%)、增城(虫口数量66头/百株、为害率20%)和珠海(虫口数量46头/百株、为害率30%),新丰最低(虫口数量6头/百株、为害率3%)。本研究为监测草地贪夜蛾首次入侵的发生和为害提供依据,并为通过调查田间种群密度指导幼虫防治工作提供技术支持。
The fall armyworn, Spodoptera furgiperda(J.E.Smith), is a new important agricultural invasive pest. Currently, S. furgiperda has invaded in Yunnan, Guangxi and Guangdong Provinces. We investigated the first larval population of the invasive adults and their damage of the pest S. furgiperda in Pearl River Delta and Northern Guangdong. The results showed that S. furgiperda has caused damage in all areas mentioned above. However, the damage caused by larvae was only found on corn. The larval population and damage rate of S. furgiperda in Conghua was the highest(222 individuals per 100 corns, 80%), followed by the Lianping(98 individuals per 100 corns, 68%), Yingde(76 individuals per 100 corns, 62%), Zengcheng(66 individuals per 100 corns, 20%) and Zhuhai(46 individuals per 100 corns, 30%), Xinfeng was the lowest(6 individuals per 100 corns, 3%). The results provide a basis for monitoring the prevalence and damage of the invasive fall armyworm, which provided some support for guiding larval control in the field.
