摘要: 将柑桔潜叶蛾种群按其生长发育顺序划分为卵(E)、1龄幼虫(L1)、2龄幼虫(L2)、3龄幼虫(L3)、4龄幼虫(L4)、蛹(P)、成虫(A)7个阶段,把各阶段的作用因子划分为相对独立的状态。根据田间调查及室内实验观察,记录各阶段的存活数,综合Beryman和宫下的方法,推算出各阶段各因子作用下的存活率,缩小了世代重叠给自种群生命表带来的误差,组建了柑桔潜叶蛾第9世代的自然种群生命表,得出其种群趋势指数为1.32,重要因子分析表明,影响柑桔潜叶蛾自然种群的重要因子是寄生性天敌。

Abstract: Based on the sequence of its growth and development, the population of citrus leafminer (Phyllocnistis citrella) was divided into such stages as eggs, 1st instar larvae, 2nd instar larvae, 3rd instar larvae, 4th instar larvae, pupae and adults. The affecting factors of each stage were divided into relatively independent status. Based on field investigation and indoor experimental observation, the survivals of each stage were recorded, and their affecting factors were estimated by synthesizing Berryman and Gongxia methods, which would reduce the errors of the natural population lifetable due to generation overlapping. The lifetable of the 9th generation of the population was constructed, and the index of population tendency was 1.32. The analysis of important factors shows that the parasite enemies were the important factor affecting the natural population of citrus leafminer.
