【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]:The insect community structure and temporal dynamics of vegetable orchard in Jinning County of Kunming in 2014 were analyzed by using species diversity homogeneity and dominance index. The results showed that 43442 insects were collected in vegetable orchard, belonging to 23 groups of 8 orders, including 13 phytophagous groups, 4 parasitic groups, 4 predatory groups and 2 other insect groups. Cocoon wasps are the dominant group, accounting for 32.940.19.52and 17.63% and 4.78% of the total, respectively. The peak of the occurrence of Liriomyza was in March-April and October-November, the peak of wasps was in April-May, and the peak of cocoon wasps was in April-April and July-November. The highest diversity index and evenness index were 2.3273 and 0.7421 in July, the lowest diversity index and uniformity index in March were 0.93760.2992, the dominant centralization index was 0.12790.5005, the highest in March and the lowest in June. The stability index of Ss/Si was 0.0011 ~ 0.1176 ~ (th) Sp = 0.4000 ~ 0.7000, which indicated that the structure of insect community was not stable. The insect communities in January and April-November were moderately different, and the insect communities in other months were moderately similar or extremely similar.
