陕西省自然景观复杂,垂直高差悬殊,地跨东洋、古北两大区,地理位置亦显重要。在约20万公里。的土地上,有乔、灌木树种达1500多种,有林地面积近1亿亩,约占全省面积的1/8。在这个绿色宝库中,昆虫资源亦极为丰富。近几年来,我们仅采到森林昆虫的寄生蜂标本即达近千种。除已在昆虫分类学报和《陕西林业科技》上发表了较为重要的60种外,本文又记述了定出种名的32种。这些均为陕西的新记录,其中也包括我国新记录10种(标本均保存在陕西省林科所内)。现分科介绍如下,错误之处,请予指正。一、姬蜂科 Ichneumonidae1.刺蛾紫姬蜂.Chlorocryptus purpura-tus Thomson寄主:青刺蛾。分布:秦岭、黄龙林区。密度:+
The natural landscape of Shaanxi Province is complex, and its vertical height difference is great. It crosses east and north of Gansu and its geographical position is also significant. At about 200,000 km. Of the land, there are more than 1,500 species of trees and shrubs, with a forest area of nearly 1 million mu, accounting for about 1/8 of the province’s area. In this green treasure house, insect resources are also extremely rich. In recent years, we have only collected nearly 1,000 species of parasitic bee specimens from forest insects. In addition to the more than 60 species that have been published in the Journal of Insect Classification and Shaanxi Forestry Science and Technology, 32 species of species have also been described. These are all new records in Shaanxi, including 10 new records in our country (all specimens are kept in the Forestry Branch of Shaanxi Province). Sub-division are introduced below, the wrong place, please correct me. First, the Ichneumonidae Ichneumonidae1. Sitchopsis viridis bee. Chlorocryptus purpura-tus Thomson Host: green thorn moth.
