豆天蛾卵寄生蜂的初步研究

<正> 豆天蛾(Clanis bilineata tsingtauica Mell)是黄淮平原夏大豆的重要食叶害虫。笔者等1985年在阜阳大豆田进行系统调查时发现,豆天蛾卵寄生率高达91.7％,其中拟澳洲赤眼蜂(Trichogramma confusum Viggiani)的寄生率为17.9％,黑卵蜂(Telenomus spp.)的寄生率为82.1％。寄生豆天蛾卵的黑卵蜂以油茶枯叶蛾黑卵蜂Telenomus(Aholcus)lebedea Chen et Tong]为优势种,寄生率占黑卵蜂总寄率的82.7％。1986年在宣城、芜湖、太湖、天长、蚌埠、和县、滁县、嘉山(明光)、宁国、桐城、蒙城、无为和合肥等地调查,寄生卵中赤眼蜂寄生率占8.6％,

PRELIMINARY STUDY ON THE EGG PARASITOIDS OF GREENISH YELLOWBROWN HAWK MOTH CLANIS BILINEATA TSINGTAINCA MELL

Greenish Yellow-brown Hawk Moth, Clanis bilineata tsingtainca Mell (CBT) is one of the most important insect pests in summe soybeans in Huang-Huai regions of China. Pest-sconting in many soybean-growing regions, Xia Pan et al have found that there are five kinds of the egg parasitoid of CBT.These species are: Trichogramma confusum Viggiani, Telenomus (Aholcus) lebedae Chen et Tong, T. tetratomus Thomson, T.angustatus Thomson, and T.sp.. A3-years study reveales that the Telenomus is the dominant natural enemies of CBT and T.(A.)Lebedae Chen et Tong is the dominant specie of the Telenomus. It can be seen that the egg parasitoids of CBT is one of the important governing factors of it. Naturat enemy will supply a new way to monitor and indicate and control of CBT.
