| 摘 要： | 该试验以桃红颈天牛(Aromia bungii Faldermann)为试材,对大连市1~15年生桃园桃红颈天牛的发生规律、幼虫平均密度和桃树受害率进行系统调查。结果表明,大连市桃园桃红颈天牛二三年发生1代,羽化期从7月初开始,发生高峰期为7月末,幼虫为害桃树主干。随着树龄的增长,桃树受害率和桃红颈天牛虫口密度显著增加,其中17~20年生的桃树受害程度最重,受害率达到88%~96%。

| Abstract: | In this experiment,used Aromia bungii Faldermann as the test material.Investigated occurrence regularity,systematically the average larval density and damage rate of 1~15 years peach trees in peach orchards in Dalian.The results showed that there was one generation of Aromia bungii Faldermann in orchard of Dalian in two or three years,and the emergence period started from the beginning of July,and the peak was at the end of July.The larvae damage the trunk of peach trees.With the increase of tree age,the damage rate and population density of Aromia bungii Faldermann increased significantly,among which 17~20 years old peach trees suffered the most serious damage,and the damage rate reached 88%~96%. |
