| 摘 要： | 为探明双斑长跗萤叶甲在黑龙江省的发生动态,2012年和2013年采用田间网捕和定点方法调查了黑龙江省哈尔滨、佳木斯和牡丹江3个地区双斑长跗萤叶甲成虫田间发生情况。结果表明:2012年和2013年3个地区双斑长跗萤叶甲发生趋势一致,表现为6月底、7月初成虫开始为害,8月中下旬种群数量达到高峰期,危害株率达80%~100%,百株虫量达625头,9月中上旬开始消退。其中哈尔滨地区发生最为严重,但扩散现象并不明显,高粱田危害相对较重。

| Abstract: | In order to search the population dynamics of M. hieroglyphica in Heilongjiang province, the incidence of M. hieroglyphica were investigated using field enmeshment and fixed point for Harbin,Jiamusi and Mudanjiang in the year of 2012 and 2013. The results showed that the occurrence tendency of M. hieroglyphica in three areas were similar, the adult was harm plant at the end of June and early of July, the population reached the peak i;n mid to late August, the occurrence ranged from 80% to 100%, insect population of one hundred plants was 625 insects began to reduce in early of September. The occurrence of M. hieroglyphica in Harbin re- gion was the most seriously,but the diffusion was not obvious, the M. hieroglyphica in sorghum field had relatively serious. |
