摘要: 新疆特有天敌资源丰富,具有重要的开发潜力和利用前景。本文通过开展新疆这一特殊生态区内玉米田主要瓢虫资源的系统调查,旨在为该地区天敌资源的保护与利用提供科学指导。本文采用网捕法结合目测法探明新疆11个地州41个县/市/区玉米种植区瓢虫群落组成。共获得1503号瓢虫标本,隶属3亚科,13属,20种,其中多异瓢虫、深点食螨瓢虫等种类为新疆玉米种植区优势种瓢虫,团聚丽瓢虫为新疆新纪录种。各玉米种植区瓢虫资源种类及个体数量间存在显著差异,其中伊犁州伊宁县最为丰富,达11种,而阿克苏地区阿拉尔市瓢虫种类最少,仅为1种。瓢虫群落多样性分析表明,伊犁州的多样性、丰富度指数和均匀度指数较高,但优势度指数较低;巴音郭楞蒙古州的多样性指数最低,且均匀度指数较低,但优势度指数最高。相似性分析表明,地州间相似性程度较高,32个地州组相似性程度相对较高,相似性系数≥ 0.5,占58.2%,其中巴音郭楞蒙古州与和田地区,所采集瓢虫相似性系数最高(0.83)。新疆玉米田间瓢虫种类和数量整体较为丰富,自然控制能力较强,这为充分保护与利用当地天敌资源,促进绿色农业的可持续发展提供科学依据。

Abstract: Xinjiang is rich in natural enemy resources and has important development potential and utilization prospect. In order to provide scientific guidance for the protection and utilization of natural enemy resources in Xinjiang, a systematic investigation of lady beetle resources in corn producing areas was carried out by the method of net capturing and visual observation. A total sample of 1503 specimens, belonging to 3 subfamily, 13 genera and 20 species was collected. Hippodamia variegate (Goeze) and Stethorus (Stethorus) punctillum (Weise) are the dominant lady beetle species in the corn growing areas in Xinjiang, Adalia conglomerata Linneaus is a new record of lady beetle species in Xinjiang. There were significant differences in the lady beetle species and population size between the corn growing areas. There were 11 species in Yining county in Yili prefecture, while there was only 1 species in Alar city in Aksu region. The diversity analysis showed that the diversity index, the richness index and the evenness index of lady beetle community were high while the dominance index was low in Yili prefecture. In Bayingolin Mongol prefecture, the diversity index was the lowest, and the evenness index was low, but the dominance was the highest. The similarity analysis showed that there was a high degree of similarity coefficients among prefectures, with similarity coefficient of 32 prefectures (accounting for 58.2% of all the prefectures) of ≥ 0.5. Among them, the similarity coefficient of lady beetles collected from Bayingolin prefecture and Hotan prefecture was the highest (0.83). Therefore, lady beetle species and population size in the corn producing areas of Xinjiang are plentiful, which guarantees a strong natural control ability, provides scientific basis for the sustainable development of green agriculture through protection and utilization of natural enemies.

Key words: Xinjiang, ladybug resources, diversity analysis, community characteristics, biological control
