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.

Key words: Frankliniella occidentalisa, kidney bean, population density, spatial distribution
