对2003~2012年桐庐地区梨花瘿蚊成虫的羽化出土时间、当地2月平均温度及梨花花蕾期之间的关系进行了研究。结果表明,2月份平均温度与成虫的出土量最多的时期两者之间的关系接近负相关。梨树小花蕾露出时间越早,梨花瘿蚊成虫羽化发生就越早。通过两者的相关性可预测梨花瘿蚊的出土时间,从而对梨花瘿蚊最好的防治时间进行预测,达到最好的杀虫、保花效果。
The relationship between the time of eclosion and the local average temperature in February and the bud stage of pear during 2003 ~ 2012 were studied. The results showed that the relationship between the average temperature in February and the period of the most unearthed adult worms was close to negative correlation. Pear small buds exposed the earlier, pear pest mosquito adult emergence sooner. Through the correlation between the two can predict the time of unearthed Eupolyphaga mosquito, so as to predict the best prevention and control time of Eupolyphaga and achieve the best insecticidal and floral protection effect.
