摘　　要：选择2016-2017年春秋2季贵州省荞麦4主产区的6个点进行蚜虫种类调查和消长规律研究,结果表明:荞麦蚜虫的种类为桃蚜、棉蚜和豆蚜3种,优势害虫为桃蚜.桃蚜的消长规律与荞麦品种、发育期、海拔有直接关系,蚜虫对甜荞的危害最大,其次是苦荞和米苦荞,多年生苦荞和矮金荞危害最小;虫口数量随着荞麦发育期逐渐增加到开花期达到最大,直到荞麦收获期下降至最低;海拔越高虫口数相对越少,反之则越多.In order to accumulate a certain amount of data for monitoring and forecasting buckwheat aphid incidence so as to improve buckwheat yield in Guizhou,an investigation was made of the species of buckwheat aphids and their fluctuation patterns at six locations of four main buckwheat-producing areas of the province in 2016-2017.The results showed that three aphid species attacked the buckwheat crop,i.e.Aphis gossypii Glover,Myzus persicae Sulzer and A.craccivora Koch,the dominant pest being M,persicae.The fluctuation patterns of M,persicae were directly related to the variety and developmental phase of the buckwheat crop and to the altitude.The aphids caused the most serious harm to Fagopyrum esculentum,followed in order by F.tataricum,F.tataricum,F.tatari-cymosum and F.megaspartanium.The population quantity increased with the growth of buckwheat,reached its maximum at the flowering period,and declined thereafter and dropped to the lowest at harvest.The population quantity varied with altitude:the higher the altitude,the less the number of this pest,and vice versa.
