【摘要】 为了掌握亚洲玉米螟在苹果园的种群增长情况,该实验通过室内系统饲养,采用组建种群生命表的方法,研究了取食苹果对亚洲玉米螟实验种群的影响。结果表明,与取食玉米叶片和人工饲料的亚洲玉米螟相比,取食苹果的种群,不仅生长发育受阻,而且其净增值率、内禀增长率和生殖力等各项参数均有所下降:其平均世代周期(57.3310天)分别比取食玉米叶(37.7170天)和人工饲料(43.5750天)的种群延长了19.6140天和14.1420天;其净增值率(1.8933)、内禀增长率(0.0111)和周限增长率(1.0112)比取食人工饲料的种群分别下降了93.66%、93.26%和14.23%,比取食玉米叶的分别下降了76.91%、80.11%和4.37%。研究表明,目前亚洲玉米螟虽然取食苹果,但其危害程度并没有达到防治指标。更多还原

【Abstract】 In order to master the population growth trends in apple orchards of the asian corn borer(Ostrinia nubitatis) ,in the experiment,the effects of feed apple to asian corn borer were studied by building host experimental population life table under indoor raise.The results showed that compared with feeding maize leaf and artificial fodder,the population feeding apple not only the gowth was restrained but also the parameters was decreased included net reproductive rate,innate capacity of increase and fecundity.The average generation time was prolonging 19.6140 d and 14.1420 d than feeding maize leaf(37.7170 d) and artificial fodder(43.5750 d) ;The net reproductive rate(1.8933) ,innate capacity of increase(0.0111) and finiterate of naturalincrease(1.0112) were decreased by 93.66%,93.26% and 14.23%,and decreased by 76.91%,80.11% and 4.37% than feeding maize leaf.Experimental research showed that the asian corn borer feeding apple at present,however,did not reach control index in the damage degree.更多还原
