| 摘 要： | 本试验通过对云南省弥渡县四季豆西花蓟马的危害情况进行研究,为四季豆西花蓟马的防治提供依据。为了更加了解西花蓟马在四季豆叶片上的空间分布格局,通过8种聚集度指标以及Iwao回归方程对四季豆叶片上的西花蓟马进行了分析,同时,比较了花期和成熟期以及叶片在绿色和浅绿色两种生长情况时,西花蓟马的空间分布情况。结果显示在四季豆叶片上西花蓟马的空间分布型为聚集分布型;成虫主要分布在四季豆上部,若虫分布在下部;若虫数量在各个时期均多于成虫数量,成熟期西花蓟马的种群数量普遍高于开花期叶片上的种群;绿色叶片上的种群数量要多于浅绿色叶片上的种群数量。四季豆西花蓟马呈聚集分布,在田间防治四季豆西花蓟马时,应该注意对若虫以及绿色叶片上的蓟马进行重点防治。

| Abstract: | This experiment studies the damage of Frankliniella occidentalisa on the kidney beans in Midu County of Yunnan Province, and provides a basis for the control of F. occidentalisa in kidney bean planting. In order to better understand the spatial distribution pattern of F. occidentalisa on leaves of kidney beans, eight kinds of aggregation indicators and Iwao regression equation were used for the analysis. Meanwhile, the spatial distributions of F. occidentalisa were compared during flowering and maturity stages and when the leaves were green and light green. The results show that the spatial distribution pattern of F. occidentalisa on kidney beans is aggregated; Adults mainly distributed in the upper part of the kidney bean, nymphs in the lower part; the number of nymphs is greater than that of adults at each stage, and the population of F. occidentalisa on the maturity stage is generally higher than that on the flowering stage; and the population is larger on green leaves than that on light green leaves. F. occidentalisa on kidney beans has an aggregated distribution, thrips on nymphs and green leaves should be the key in controlling F. occidentalisa on kidney beans in field. |
