通过系统调查和室内观察,采用平均历期法,组建以作用因子组配的桔全爪螨自然种群生命表。组配自然种群生殖力表,以内禀增长率(rm)等作为判断桔全爪螨种群数量发展趋势的指标。分析结果表明,在春季天敌对桔全爪螨种群数量的控制作用是明显的,但天敌作用不足以控制桔全爪螨种群数量的增长,需辅以其他措施进行控制。
Through systematic investigation and indoor observation, the average duration method was used to establish the life table of natural populations of Allopteryx javanica distributed by action factors. Group natural fecundity table, with the intrinsic rate of increase (rm) as an indicator to determine the number of population development trend of the orange full-mite index. The results showed that the control effect of natural enemies on the population size of P. militaris was obvious in spring, but the effect of natural enemies was not enough to control the population growth of P. militaris, which should be supplemented by other measures.
