黑龙江省大兴安岭地区小蠹虫与天敌寄生蜂相互关系的研究

PARASITIC WASPS AND SCOLYTIDAE INSECTS IN DAXINGANLING MOUNTAINS OF HEILONGJIANG PROVINCE

通过对大兴安岭地区小蠹虫寄生蜂的种类和自然寄生率的调查 ,共发现有小蠹虫寄生蜂 1 3种 ,其中茧蜂科 4种 ,广肩小蜂科 2种 ,金小蜂科 6种 ,姬小蜂科 1种 ;分析了天敌寄生蜂的自然控制作用 ,发现天敌寄生蜂对小蠹幼虫的寄生率为 5.41 % ,对小蠹蛹的寄生率为 8.46% ,对小蠹成虫的寄生率为0 .3 3 %

The species and naturally parasitic rates of parasitic wasps parasiting on Scolytidae Insects have been gathered in Daxinganling Mountains of Heilongjiang Province. There are 13 species of the parasitic wasps of scolytidae insects, of which 4 species in Braconidae, 2 species in Eurytomidae, 6 species in Pteromalidae, 1 speccies in Eulophidae. And the naturally control action has been analysised. the Results are as follow:the parasitic rate of larvae, pupae and adults is 5.41%, 8.46% and 0.33%.
