| 摘 要： | 金龟子是危害板栗的一种重要害虫,在生产中表现为经常将板栗幼树的嫩叶吃光,造成2次长叶,使板栗的初花最佳授粉时期光合效能减弱,影响板栗的产量和质量。在2008～2010年期间,作者对嫁接后的板栗幼林中金龟子发生规律和生活史进行了调查,利用金龟子的"假死性"特点,采取人工捕捉措施、以及加强营林管理技术等无公害防治方法进行了防治。结果表明:这种防治措施可以大幅度地减少虫口数量,控制翌年虫口发生密度,达到了有害不成灾的效果。

| Abstract: | Scarab beetles is an important pest harming Castanea mollissima,which often eat out the tender leaves in the production process,resulting in secondary growing leaves and weakening chestnut photosynthesis efficacy during the optimum pollination period of flowering,affecting the yield and quality of Castanea mollissima.During 2008 to 2010,the authors proceeded a survey on scarab occurrence and life history in grafted Chestnut plantation.By using the feature of ＂suspended animation＂,the authors adopted the measures of manual capture,and enhanced forest management technology of non-pollution to prevent and cootrol the pest.The results showed that such prevention and cootrol method can greatly reduce the number of pest,and control the insect population density of the following year,realizing the effects of doing harm but no disasters. |
