为明确加州新小绥螨Neoseiulus californicus(McGregor)国内种群对朱砂叶螨Tetranychus cinnabarinus(Boisduval)的控制潜力,应用功能反应、数值反应及实验种群生命表参数评价了该捕食螨对朱砂叶螨的控制能力。加州新小绥螨对朱砂叶螨的功能反应能很好地拟合HollingⅡ方程。在25℃,加州新小绥螨雌成螨对朱砂叶螨卵、幼螨、若螨和成螨的功能反应参数a/Th值分别为42.4195、81.6275、54.3044和17.9399,对朱砂叶螨幼螨、若螨和卵的控制力高于成螨。在19~31℃,加州新小绥螨对朱砂叶螨雌成螨日均捕食量和对猎物的控制能力a/Th随温度升高而增大,在31℃时达最大值,分别为10.80头和29.5364。在28℃时,加州新小绥螨的净增殖率和内禀增长率分别为26.1522和0.2213。表明加州新小绥螨国内种群表现出重要的生物防治潜能。
In order to clarify the control potential of domestic populations of Neoseiulus californicus (McGregor) on tetranychus cinnabarinus (Boisduval), functional control, numerical response and experimental population life table parameters were used to evaluate the control of Tetranychus cinnabarinus ability. The functional response of Neospora californicus to Tetranychus cinnabarinus fits the HollingⅡ equation well. At 25 ℃, the functional response parameters a / Th of the adult Neosputus mites were 42.4195,81.6275,54.3044 and 17.9399, respectively. If the control of mites and eggs than adult mites. At 19 ~ 31 ℃, the average daily food intake and the control ability a * Th of adult Neospongs were higher at 31 ℃, which were 10.80 Head and 29.5364. At 28 ℃, the net growth rate and intrinsic rate of increase of Neospora calystatus were 26.1522 and 0.2213, respectively. This indicates that the domestic populations of N. succinus exhibit an important biological control potential.
