【摘要】：利用捕食性天敌昆虫在自然界中的调控作用,以虫治虫,控制虫灾,是保证农业增产、保护农业清洁环境的有效途径,也有利于实现农业生态平衡、保护生物多样性和实现人与各种生物和谐相处的崇高目标。本文基于京津冀地区天敌昆虫标本采集、物种鉴定和文献资料整理与分析,对该地区捕食性天敌昆虫的种类与多样性进行了调查研究,为此,首先要摸清农林牧业生态环境中的天敌昆虫种类,它们的多样性组成和优势种类发生情况。取得了如下结果：1、经标本鉴定和相关文献整理,获得京津冀地区捕食性天敌昆虫共计16目101科632属1580种。其中以鞘翅目、双翅目、膜翅目、半翅目和蜻蜓目5目昆虫占据优势,种类总数达到68科548属1442种,分别占该地区已知捕食性天敌昆虫总数的67.33%、86.71%和91.27%。2、依据Holt等的世界动物地理区11界意见,京津冀地区捕食性天敌昆虫凸显中日界成分,物种总数达到478种,占该地区已知捕食性天敌昆虫昆虫总数的30.25%；其次是中日界+古北界+东洋界共有种类,占总数的28.04%；再次是中日界+古北界共有成分和中日界+东洋界共有成分,分别占总数的23.16%和18.54%。该数据表明,京津冀地区是中国日本动物区昆虫的典型的分布区,其与古北界和东洋界的共有物种交流十分丰富,同时又保留了大量的特有种类。3、依据张荣祖等的中国动物地理2界、3亚界、7区、19亚区区划意见,京津冀地区主要位于华北区,与东北区、蒙新区、华中区毗邻。在该地区的捕食性天敌昆虫中,只分布于华北区的种类多达430种,占总数的27.25%；通过跨区分布类型比较,华北区与华中区跨区分布的昆虫类型为781种(49.43%),与华南区跨区分布的昆虫类型为639种(40.44%)。说明该地区与华中区、华南区的联系较为紧密。究其原因,可能由于京津冀地区的南部与华中区不存在明显的地理屏障,而北部与东北区和蒙新区存在地理屏障有关。
[Abstract]:It is an effective way to ensure the increase of agricultural production and to protect the clean environment of agriculture by using the control function of predatory natural enemy insects in nature to control insects and insect pests. It is also beneficial to realize the balance of agricultural ecology. Protect biodiversity and achieve the noble goal of harmony between man and all living things. Based on the collection of natural enemy insect specimens, species identification and literature analysis in Beijing-Tianjin-Hebei region, the species and diversity of predatory natural enemy insects in this area were investigated and studied. First, the species of natural enemy insects in the ecological environment of agriculture, forestry and animal husbandry, their diversity composition and the occurrence of dominant species should be found out. The results are as follows: 1. Through specimen identification and literature review, 1580 species of predatory insects belonging to 632 genera, 101 families and 16 orders in Beijing, Tianjin and Hebei are obtained. Among them, Coleoptera, Diptera, Hymenoptera, Hemiptera and Odonata are the dominant insects, and the total species amount to 68 families, 548 genera and 1442 species. It accounts for 67.336.71% and 91.27.2% of the total number of known predators in this area respectively. According to Holt's opinion of 11 world zoogeographic regions, the predatory natural enemy insects in Beijing-Tianjin-Hebei area highlight the Japanese elements, and the total species amount to 478 species. It accounts for 30.25 of the total number of known predators in this area, followed by the common species of the Middle Japanese Palaearthen and the East Ocean, accounting for 28.04 of the total. Again, there are common components in the Meso-Japanese Paleo-Northern and Central Japanese Orientals. They accounted for 23.16% and 18.54% of the total, respectively. The data show that the Beijing-Tianjin-Hebei region is a typical distribution area of insects in the Japanese fauna of China. At the same time, a large number of endemic species. According to Zhang Rongzu's opinion on the division of 2 boundaries, 3 subboundaries, 7 sub-regions and 7 subregions of China's animal geography, the Beijing-Tianjin-Hebei region is mainly located in North China, adjacent to the northeast region, the new area of Mongolia and the central China region. Among the predatory natural enemy insects in this area, there are only 430 species distributed in North China, accounting for 27.25% of the total. The insect types in North China and Central China are 781 species and 49.43 species, and 639 species and 40.44 species in South China. It shows that this area is closely connected with central China and South China. The reason may be that there is no obvious geographical barrier in the south of Beijing-Tianjin-Hebei region and central China, but the geographical barrier in the north is related to the existence of geographical barrier in the northeast region and the new area of Mongolia.
