【摘要】 本文是关于应用Wyatt-White方法计算寄生物种群内禀增长率的研究。研究表明:r_m的精确值与ln（M_d）/d或ln(M_{d/ 2})/d之间存在着线性关系,这种关系可表达如下:（1）r_m=0.845ln（M_d）/d;（2）r_m=0.880ln(M_d/2/d。这里d为生殖前期;M_d为生殖起d天内每个原始雌虫产下的平均雌性后代数;M_d/2为生殖起初d/2天内每个原始雌虫产下的平均雌性后代数。运用23组生殖力表资料,研究表明公式1—2可以给出r_m的精确估计值,公式2的估计效果更好。这种方法不要求组建生殖力表。该方法是否适用于其它寄生物种群或其它生物类群有待进一步研究。更多还原

【Abstract】 The method developed by Wyatt and White (1977) was applied to calculate the intrinsic rates of increase for parasitoids based on 23 fecundity data sets from the literature. The studies showed that there existed the linear relationship between the accurate values of rm and In f (Md) / d or In (A/d/2) / d, that is, 1) rm= 0.845 In (Md) / d or 2) rm= 0.880 In (Md/ 2) / d. Where d is the prereproductive time, Md is the number of female offspring produced per original female from the first to the dthday of reproduction, and Md/2 is the number of female offspring produced per original female from the first to the (d/ 2) th day of reproduction. These equations can provide the accurate estimates of rm for parasitoids in this study. The approach is advantageous because it does not require the construction of detailed fecundity tables for estimating parasitoid rates of increase. Of course, whether these equations are appropriate for the other taxa will need to be further studied.更多还原
