摘要: 为了明确不同温度对取食玉米籽粒桃蛀螟生长发育、存活和生殖的影响,本研究依据年龄-龄期两性生命表理论计算了在21、24、27和30 ℃下取食玉米籽粒的桃蛀螟种群的生命表参数,并基于这些参数预测了未来80 d的种群动态。结果表明: 在21、24、27和30 ℃下桃蛀螟均能完成1个世代,随着温度升高,各阶段的发育历期缩短,且温度间差异显著。24 ℃下的平均单雌产卵量最高(116.7粒),成虫前期存活率最高(84.7%),雌虫占比最高(0.46),均显著高于其他温度。24、27、30 ℃下种群的内禀增长率分别为0.1059、0.1101、0.1045 d-1,周限增长率分别为1.1117、1.1164、1.1102 d-1,处理间差异不显著,但均显著高于21 ℃处理。21、24、27和30 ℃下的净增殖率(R0)分别为17.3、53.7、36.9、19.8个后代个体,其中24 ℃时的R0最高且显著高于其他温度处理。表明桃蛀螟种群在24~27 ℃下的存活率高、繁殖力大、雌性占比较高,是其生长发育、生存和繁殖的适合温度。

Abstract: In order to examine the effects of temperature on the growth, survival, and reproduction of Conogethes punctiferalis (Lepidoptera: Crambidae) feeding on corn kernels, the life table parameters of C. punctiferalis at 21, 24, 27, 30 ℃ were calculated based on the age-stage two-sex life table theory, and then population dynamics of C. punctiferalis was projected based on these parameters. The results showed that the life cycles of the pest could be finished at all the four temperature treatments. The developmental duration of each stage shortened with increasing temperature, and there were significant differences among treatments. The highest fecundity (116.7 eggs per female), preadult survival rate (84.7%), and proportion of female (0.46) were observed at 24 ℃. The intrinsic rates of increase at 24, 27, 30 ℃ were 0.1059, 0.1101, and 0.1045 d-1, respectively. The finite rates of increase were 1.1117, 1.1164, and 1.1102 d-1, respectively. There was no significant difference among the three treatments, but the r and λ values were significantly higher than those at 21 ℃. The net reproductive rates (R0) at 21, 24, 27, 30 ℃ were 17.3, 53.7, 36.9, and 19.8, respectively. R0 at 24 ℃ was the highest. It suggested that survival rates, fecundities and female proportions of C. punctiferalis population were high at 24-27 ℃, which was the suitable temperature range for its growth, survival, and reproduction.
