本文研究了德氏钝绥螨发育速率、繁殖率与温度的关系以及德氏钝绥螨对桔全爪螨的功能反应、数值反应及不同螨态的选择捕食作用。在此基础上,组建了德氏钝绥螨—桔全爪螨种群数量变动的模拟模型,并在四种不同释放钝绥螨的条件下,进行了桔全爪螨种群数量变动的模拟实验,从而得出了最佳的释放钝绥螨时间、数量、频率及螨态。 In this paper, the relationship between the developmental rate of Aesculus terrestris and the temperature, and the functional response, numerical response and the selective predation of A. mongolicus to P. militaris were studied. On this basis, a simulation model of the population change of Amblyseius mite-Citrus grandis was established, and the simulation experiments on the population dynamics of the species Allium mongolicus were carried out under the conditions of four kinds of different release Amblyseius mites. Thus, the best time to release Amblyseius, its quantity, frequency and mite state was obtained.
