摘要
一种杨树新害虫杨枝瘿潜蝇Euhexomyza schineri(Giraud,1861)近些年在内蒙古部分地区被发现,之前国内只在青海省有分布记载。该文研究杨枝瘿潜蝇的生物学特性、对不同种杨树的寄主选择以及对其防治的试验。杨枝瘿潜蝇为害杨树枝梢并刺激形成虫瘿,一年1代,以2龄幼虫越冬,翌年5月为羽化期。杨枝瘿潜蝇对河北杨的为害最为严重,新疆杨和加拿大杨次之。杨枝瘿潜蝇成虫羽化期短,是化学防治的最佳时期。
Euhexomyza schineri(Giraud,1861),a new pest of poplar trees,has been discovered in some areas of Inner Mongolia in recent years.Previously,its distribution in China was only recorded in Qinghai Province.This study investigated the biological characteristics of Euhexomyza schineri,its host selection among different poplar species,and conducted experiments on its control.Euhexomyza schineri infests poplar twigs and stimulates the formation of galls.It has one generation per year,with secondinstar larvae overwintering and adults occurring in May of the following year.The damage caused by Euhexomyza schineri is the most severe on Populus hebeiensis,followed by Populus alba and Populus canadensis.The adult emergence period of Euhexomyza schineri is short,making it the optimal time for chemical control.
