摘要： 在26±1℃恒温和食物充足的条件下,豚草条纹叶甲种群每一世代以59倍的速率增殖。其内禀增长力为0.06772,瞬时出生率和瞬时死亡率分别为0.31753和0.24981。世代的平均历期为66.5天。种群平均日增长1.07倍。种群存活呈DeeveyⅡ型分布,雌虫年龄特征存活率呈Ⅰ型分布。种群年龄组配为:卵占37.44％、幼虫占45.08％、蛹占12.05％、成虫占5.43％。

Abstract: The life table of Zygogramma suturalis was constructed based on the laboratory studies conducted during 1987 to 1988. The experimental population with sufficient food supply multiplied for 59 times under the constant temperature of 26℃. The population intrinsic rate of increase was found to be 0.06772. The instantaneous birth rate and death rate were 0.36157 and 0.29386, respectively. The average developmental period for one generation was 66.5 days. The general survival rate and the female age-specific survival rate were found to fit Deevey\'s Ⅱ and Ⅰ types, respectively. The egg, larva, pupa and adult accounted for 37.44%, 45.08%, 12.05%, and 5.43%, respectively, of the theoretically stable population of the species.
