摘要: 应用标记-回收技术,研究了寄主及气象因素对黄曲条跳甲种群扩散的影响.结果表明,黄曲条跳甲的自然扩散是由环境引起(τ≈1),温度、风速与之有一定的相关性(P<0.05),高温不利于黄曲条跳甲的扩散,其扩散主要沿逆风或与风向垂直方向进行,而湿度与黄曲条跳甲成虫扩散无显著相关(P>0.05).寄主是影响黄曲条跳甲扩散的重要因子,在几种寄主植物中,菜心上收集的标记成虫数最多,其次为芥菜,再次为白菜,芥蓝上基本没有.

Abstract: Using marking recapture method,this paper studied the effects of host plants and climatic factors on the dispersion of Phyllotreta striolata adults.The results showed that the dispersion of the beetle was impelled by environment elements (τ≈1).Temperature and wind speed had significantly positive correlations with the dispersion of the beetle (P<0.05),while high temperature had a negative correlation.Wind orientation had a significant effect on the dispersion of the beetle,with the adults mostly flying against or vertically to the wind.Humidity contributed little to the dispersion (P>0.05). Host plant was one of the important factors affecting the dispersion of the beetle.Among the plants studied,flowering Chinese cabbage ranked first in capturing marked adults,followed by mustard and Chinese cabbage,while nearly no marked adults were captured on Chinese kale.
