| 摘 要： | 利用黄板诱集方法，监测黄曲条跳甲（Phyllotreta striolata）田间成虫的数量动态，发现该虫在福州全年均可发生危害，没有明显的越冬现象。2002～2003年共出现4个较为明显的成虫发生高峰和3个明显的成虫数量低谷。田间成虫数量与降雨、气温的相关分析表明，黄曲条跳甲的成虫发生与降雨、气温的关系不显著，但受到降雨、气温的复合作用。黄曲条跳甲成虫在不同寄主上的发生量存在明显的差异，数量变化在一茬菜的生长过程中也不同。黄曲条跳甲成虫对寄主具有明显的选择作用。

| Abstract: | With yellow trap board as monitoring tool,this paper studied the quantitative dynamics of striped flea beetle (SFB) P.striolata adults in field.The results showed that from Nov.2002 to Oct.2003,there were four insect occurrence peaks and three vales,which meant that SFB occured a year around,with no evident overwintering phenomena.The occurrence of SFB population was not significantly affected by rainfall or temperature,while joint effect of the two factors was existed.The quantitative dynamics of SFB were various on different host plants,as well as in different growth stages of vegetables,indicating the host discrimination of SFB adults. |
