摘要: 应用物种多样性、均匀性、优势度指数等测定分析了2014年昆明晋宁县蔬菜园昆虫群落结构及时间动态特征。结果表明,蔬菜园共收集到昆虫43442头,隶属8目23个类群,包括植食性13个类群、寄生性4个类群、捕食性4个类群和其他昆虫2个类群,其中潜蝇类、苍蝇类、小蜂类、茧蜂类昆虫为优势类群,分别占总数的32.94%、19.52%、17.63%和4.78%;潜蝇类发生高峰期在3-4月和10-11月,小蜂类发生高峰期在4-5月,茧蜂类发生高峰期在4-5月和7-11月;7月多样性指数和均匀性指数最高为2.3273和0.7421,3月多样性指数和均匀性指数最低,分别为0.9376、0.2992;优势集中性指数为0.1279~0.5005,3月最高,6月最低;Ss/Si稳定性指数为0.0011~0.1176,Sn/Sp稳定性指数为0.4000~0.7000,说明昆虫群落结构稳定性差;1月与4-11月昆虫群落中等不相似,其他月份之间昆虫群落表现为中等相似或极相似。

Abstract: In 2014, the species diversity index, evenness index and dominance index were used to analyze the insect community structure and temporal dynamics in the vegetable garden in Jinning county, Kunming. A total of 43442 insect samples were collected and the insects belonged to 8 orders, 23 taxa, which included 13 phytophagous taxa, 4 parasitic taxa and 2 others taxa. Liriomyza, Muscidae, Chalcididae and Braconidae were the dominant species, accounting for 32.94%, 19.52%, 17.63% and 4.78% of the total samples, respectively. Population peak of Liriomyza was March-April and October-November;population peak of Chalcididae was April-May;Population peak of Braconidae was April-May and July-November;The diversity index and evenness index reached peak in July, the maximum was 2.327 and 0.7421, respectively, while the minimum in March was 0.9376 and 0.2992, respectively. The variation range of dominant concentration index was 0.1279-0.5005, the maximum was in March and the minimum was in June. Ss/Si (the number of species divided by the number of individuals) was between 0.0011 and 0.1176, Sn/Sp (the number of natural enemy species divided by the number of phytophagous species) was between 0.4000 and 0.7000. Value of Ss/Si and Sn/Sp indicated that the stability of insect community structure was worse. The structure of insect community was moderately different in January and April-November, but moderately similar or very similar in other months.

Key words: vegetable garden, structure of insect community, temporal dynamics
