摘要
欧洲栗象是具有经济重要性的林业害虫,对栗属和栎属植物能造成毁灭性损失,能严重降低板栗的产量和口感,影响种子发芽力和种苗活力。本文主要介绍了欧洲栗象的地理分布、寄主、形态特征、生物学特性、经济影响、防治措施等内容。该虫在我国尚无分布,深入研究该虫的为害特点和扩散途径等,对防治该虫有重要意义。
Curculio elephas is one of the most economically important forestry pests. It can cause destructive dam- age to chestnut（Castanea spp. ） and oak（Quercus spp. ）, reduce marketable yield, make nuts unpalatable, de- crease percent of germination, and have a negative effect on seedling vigour. This paper gives a general introduction of its geographic distribution, hosts, morphology, biology, impact, control, et al. For there is no C. elephas in China, it is of great significance to prevent this pest by learning more about its damage characteristic and diffusion path.
