摘要
在（23±1）℃、光照时间16 h、相对湿度70%~80%人工气候箱条件下,研究了＂草豌豆＂、＂定豌1号＂、＂定豌2号＂、＂G1997＂4个豌豆品种对绿色型豌豆蚜种群变化的影响,旨在为种植豌豆时品种的选择提供理论依据。结果表明,在不同豌豆品种上绿色型豌豆蚜的各虫态发育历期和单雌一生最高产仔量均有显著差异,其在＂G1997＂上完成一生所需时间最长（17.92 d）,在＂草豌豆＂上最短（12.69 d）;其最高产仔量在＂G1997＂上最多,为117头.头1,在＂草豌豆＂上最少,为60头·头^-1。存活曲线均为Ⅰ型,存活率高低依次为＂G1997＂、＂定豌2号＂、＂定豌1号＂和＂草豌豆＂;净增值率＂定豌2号＂、＂定豌1号＂、＂G1997＂、＂草豌豆＂相应分别为40.569 2、37.952 4、31.607 8、25.000 0;内禀增长率在＂定豌1号＂上最大,为0.275 8,而在＂G1997＂上最小,为0.188 6;种群加倍时间依次为＂G1997＂（3.675 0 d）、＂定豌2号＂（2.867 6 d）、＂草豌豆＂（2.729 8 d）和＂定豌1号＂（2.513 1 d）;＂定豌1号＂是其最喜食的品种,其次为＂定豌2号＂、＂草豌豆＂,最后是＂G1997＂。
Pea aphid,Acyrthosiphon pisum（Harris）（Hemiptera： aphidiae）,is a destructive agricultural pest of a wide range of leguminous crops.Pea aphids have strong reproductive capacity,especially green morph of pea aphid.To build the theoretical basis for garden pea variety selection and comprehensive treatment for A.pisum,the effects of four different garden pea cultivars（＂Grass pea＂,＂Dingwan1＂,＂Dingwan2＂ and ＂G1997＂） on population change of green morph of A.pisum were investigated under constant temperature [（23±1） ℃],relative humidity（70%~80%） and illumination time（16 h）.The study determined the demographic characteristics of the green morph of A.pisum,including population parameters,developmental duration,fecundity and survival.The results showed significant differences in the durations of different developmental stages and highest fecundity per female lifetime of the green morph of A.pisum in the four different garden pea cultivars.The generation was longest（17.92 d） in ＂G1997＂ and shortest（12.69 d） in ＂Grass pea＂.The highest fecundity per female lifetime（117） was in ＂G1997＂ and the lowest（60） in ＂Grass pea＂.All the survival curves were of Deevey type I.The net reproductive rates（R0） were 40.569 2,37.952 4,31.607 8 and 25.000 0 in ＂Dingwan2＂,＂Dingwan1＂,＂G1997＂ and ＂Grass pea＂,respectively.The intrinsic rate of increase（rm） was maximum（0.275 8） in ＂Dingwan1＂ and minimum in ＂G1997＂.The survival rate was highest in ＂G1997＂,followed by ＂Dingwan2＂,＂Dingwan1＂ and ＂Grass pea＂.The time（t） for population doubling of the green morph of A.pisum in ＂G1997＂,＂Dingwan2＂,＂Grass pea＂ and ＂Dingwan1＂ was 3.675 0 d,2.867 6 d,2.729 8 d and 2.513 1 d,respectively.Furthermore,the mean generation time（T） was minimum（12.679 3 d） in ＂Grass pea＂ and maximum（18.314 5 d） in ＂G1997＂.The results indicated that green morph of A.pisum population in the pea cultivars decreased in order of ＂Dingwan1＂ ＂Dingwan2＂ ＂Grass pea＂ ＂G1997＂.
