为明确黄曲条跳甲成虫在浙北地区的季节性消长规律及其影响因子,2005~2007年在浙江海宁,采用黄板诱集的方法,逐日观察黄曲条跳甲成虫数量变化。从发生情况看,黄曲条跳甲1年中有2个发生高峰期,即4~6月的春季发生高峰期和8~10月的秋季发生高峰期,春季高峰的诱集数量是秋季高峰的2.3倍。根据逐日成虫数量以及气温、降水量等数据进行线性回归分析,结果表明8~10月成虫种群数量变化与种群基数成极显著的正相关,与温湿系数呈显著的负相关,但温度与种群数量相关不大。因此影响黄曲条跳甲成虫种群数量的关键因子是种群基数和温湿系数。
In order to clarify the seasonal pattern of the growth and decline of Bemisia tabaci adults in the north of Zhejiang and its influencing factors, the number of adults of Bemisia tabaci (Diptera: Bemisia tabaci) adults was observed daily by means of yellow plate trapping from 2005 to 2007 in Haining, Zhejiang. Occurred from the situation, the Yellow Striped beetle 2 peaked in 1 year, that is, from April to June in the spring peak and 8 to October in the autumn peak, the spring peak of the number of seasons is the peak fall 2.3 times. The linear regression analysis based on the number of adults and the data of temperature and precipitation showed that there was a significant positive correlation between the number of adult population and the population base number in August to October and negatively correlated with the temperature and humidity coefficient, Relatively small number. Therefore, the key factors influencing the population of Bemisia tabaci adults are population base and temperature and humidity coefficient.
