摘要: 为探究信阳市油茶园灯下昆虫群落多样性及动态，于2015年5月-2016年10月采取诱虫灯诱集的方法对信阳市油茶主要产区昆虫群落开展系统调查.结果表明：信阳市油茶园灯下昆虫共9目55科120种，主要以鳞翅目和鞘翅目昆虫为主，占总科数的60%，占总物种数的69.17%；为害油茶的主要优势种为斜纹夜蛾Prodenia litura，铜绿丽金龟Anomala corpulenta、螺纹蓑蛾Clania crameri、桃蛀螟Conogethes punctiferalis，茶蓑蛾Clania minuscula等；6、7、8月三个月份为油茶园昆虫活动的高峰期，Shannon多样性指数2016年整体上要高于2015年，2015年为6月份最高，达4.1067，2016年为7月份最高，达4.3994，均匀度指数波动也较为平稳，2015年为6月份最高，达0.8213，2016年为8月份最高，达0.9337.本研究为该区域油茶害虫的监测预报与综合防治提供了理论依据.

Abstract: To explore the diversity and dynamic of insects under the lamps in Camellia oleifera garden of Xinyang city,it was adopted the method of luring-lamp to carry out systematic investigation on insect communities in Camellia oleifera's main producting area of Xinyang city from May 2015 to October 2016. The result showed that insects were trapped under the lamp in Camellia oleifera garden of Xinyang city belonging to 9 orders, 55 families, 120 species, the lepidoptera and coleoptera were the main insects, which account for 60% of the total families and 69.17% of the total species. The main dominant pests species were Prodenia litura, Anomala corpulenta, Clania crameri, Conogethes punctiferalis, Clania minuscula and so on. The peak of insect activity in Camellia oleifera garden was in June, July and August. The Shannon diversity index in 2016 was higher than that in 2015, the highest in June 2015, reaching 4.1067. And in July 2016 the index was the highest, which reached 4.3994. And the Pielou index was fluctuates smoothly, the highest in July 2015, reaching 0.8213,in August 2016 the index was the highest, which reached 0.9337. This study provides theoretical basis for monitoring, predicting and comprehensive protection of Camellia oleifera pests in this area.
