| 摘 要： | 通过在29℃恒温条件下的饲养观察,组建了黄曲条跳甲年龄特征生命表和繁殖特征生命表,并计算出反映种群增长动态的几个重要参数.结果表明:黄曲条跳甲世代总存活率为0.58,种群趋势指数为88.01,净繁殖率为87.8879,世代平均历期为43.9 d,内禀增长能力为0.1020,瞬时出生率和死亡率分别为0.2720、0.1700,周限增长率为1.1074,双倍时间为6.8d;在稳定年龄组配中,未成熟期(卵、幼虫、蛹)年龄组占88.94%,成虫期年龄组占11.06%.

| Abstract: | By studying experimental population of striped flea beetle,Phyllotreta striolata(Fabricius),the age specific life table and fecundity specific life table were constructed.The population parameters such as survival rate of generation(0.58),trend index of population(I=88.01),net reproductive rate(R0=87.8879),mean generation time(T=43.9),innate capacity for increase(rm=0.1020),instantaneous rates of birth and death(b=0.2720;d=0.1700),finite rate of increase(λ=1.1074) and doubling time(DT=6.8) were obtained.Stable age composition was as follows: the age period of immature population accounted for 88.94%,the age period of adult population accounted for 11.60%. |
