摘要
在6种温度、5种粮食水分下,测定了玉米象的内寨增长力(r_m)和理论的稳定年龄组配.温度在28℃时内禀增长力(r_m)最大,在18-32℃范围内玉米象实验种群的内禀增长力呈抛物线趋势,在粮食水分为11.5-15.5%范围内,随着粮食水分的升高,玉米象的内禀增长力增大;玉米象种群的理论稳定年龄组配中,未成熟期占有很高的比例.
This paper dcalt with the innate capacity for increase (r_m) and stable age-distribution of maize weevil under the conditoin of six temperatures and five moisture contents of grain. r_m was the greatest at 28℃. r_m appears parabola from 18℃ to 32℃ and increased with the increase of the moisture content of grain. The adultiod had a large proportion in the stable age-distribution of the maize weevil population.
