摘　　要：通过野外直接采卵(寄生昆虫卵)和野外挂卵(米蛾杀胚卵)诱集的方法,开展了广东省本地赤眼蜂野外采集工作。利用雄虫的外生殖器特征及ITS2序列聚类分析方法对采获的赤眼蜂种类进行鉴定,目前已鉴定出7个不同的赤眼蜂种类,其中小灰蝶分索赤眼蜂Trichogrammatoidea hypsipylae Nagaraja为中国新记录种,广赤眼蜂Trichogramma evanescense Westwood,食胚赤眼蜂Trichogramma embryophyagum(Harting)及暗黑赤眼蜂Trichogramma pintoi Voegele为广东省内首次采获。采集鉴定结果表明,广东省本地具有丰富的赤眼蜂优质种质资源,可为害虫生物防治提供更大的筛选利用空间。Collection of native Trichogramma has been carried out in field eggs directly and hanging the egg cards of Corcyra cephalonica （Stainton） by means of searching insect The collected species of Tri- chogrammatidae were identified by the characteristic of male genitalia and ITS2 cluster analysis. At present, 7 different Triehogrammatidae species have been identified, among which, Trichogrammatoidea hypsipylae Nagaraja was the New Records in China, T. evanescense Westwood, T. embryophyagum （Hatting） and T. pintoi Voegele were collected for the first time in Guangdong Province. The results showed that there were abundant and high quality germplsm resources of Trichogramma in Guangdong Province, which will supply more opportunities for biological control of insect pests.
