摘　　要：大豆胞囊线虫病在黑河地区普遍发生,为明确黑河地区大豆胞囊线虫群体分布及生理小种的变化,分别在2010年和2019年对黑河地区开展大豆胞囊线虫种群的监测工作。结果表明:该病在黑河地区均有分布,在两次监测过程中发现土壤中胞囊密度有下降的现象。3号生理小种目前是黑河地区的优势小种,在2010年的调查中在五大连池市双泉镇、孙吴县腰屯乡发现有6号生理小种。2019年调查中发现各采样点大豆胞囊线虫病均为3号生理小种,未检出6号生理小种。Soybean cyst nematode(SCN)disease,caused by Heterodera glycines,occurs widely in the Heihe area.In order to clarify the changes of population distribution and physiological races of SCN in Heihe area,we monitored SCN race in Heihe area in 2010 and 2019 respectively.The results showed that:Soybean cyst nematode disease is widely distributed in Heihe area.In the two monitoring,the cysts numbers of SCN decreased.The pathogenicity differentiation of SCN wasn′t significant change,identification of races were the race 3.In 2010,race 6 was found in Shuangquan town of Wudalianchi city and Yaotun town of Sunwu County.The survey in 2019 found that the soybean cystic nematode disease was SCN 3,and SCN 6 was not found.
