摘要
系统调查了大豆蚜在3个大豆品种(辽豆15、辽豆18和辽豆22)上的种群发生动态,并在温室自然变温条件下利用小纱网笼罩法组建了大豆蚜在这3个大豆品种上的实验种群生殖力表,以了解不同大豆品种对大豆蚜的抗性差异。结果表明:大豆蚜在辽豆22上发生量明显低于辽豆18和辽豆22。种群净增殖率(Ro)、平均世代历期(T)和内禀增长率(rm)参数值均表现为辽豆18>辽豆15>辽豆22。因此,在3个大豆品种中,辽豆22最不适合大豆蚜生长发育和繁殖。
Soybean aphid,Aphis glycines Matsumura,is an important agriculture pest in China.It heavily damaged soybean and had caused serious economic losses in some main soybean production areas.To understand the resistance difference to soybean aphid in soybean cultivars,this study examined the population dynamics of Aphis glycines on three soybean cultivars（LD15,LD18 and LD22）in fields,and then used small clip cages to build the fecundity table of experiment population of soybean aphids on three soybean cultivars in the greenhouse.The results showed that the amounts of soybean aphids in LD22 were fewer than LD15 and LD18.The parameters size of the net reproductive rate（Ro）,the mean generation time（T）and the intrinsic rate of increase（rm）of soybean aphid were LD18LD15LD22.Consequently,the study suggested that LD22 was the most unsuitable cultivars for the growth and reproduction of soybean aphid.
