中文摘要:为探究加州新小绥螨Neoseiulus californicus(McGregor)对侧多食跗线螨Polyphagotarsonemus latus(Banks)的潜在控制能力,在温度19~31℃、相对湿度(75±5)%条件下应用捕食功能反应模型研究了加州新小绥螨对侧多食跗线螨各螨态的捕食作用。结果表明,加州新小绥螨对侧多食跗线螨的卵、幼螨、若螨和雌成螨的选择性捕食系数分别为0.64、1.50、0.77和1.09。不同温度条件下,加州新小绥螨对侧多食跗线螨的捕食功能反应均属于Holling Ⅱ型,对猎物幼螨和雌成螨的控制能力最强;28℃时加州新小绥螨的捕食能力最强,对侧多食跗线螨卵、幼螨、若螨和雌成螨的攻击系数分别为0.45、0.97、0.79和0.82;最大日捕食量分别为27.10粒、71.94、32.79和35.21头。加州新小绥螨的捕食作用存在较强的种内干扰反应,随着捕食者密度增加,捕食作用率下降,28℃时捕食作用率与其自身密度的关系为E=0.4345P-0.6278。表明加州新小绥螨对侧多食跗线螨有很好的控制潜力。 |

Abstract:In order to explore the potential control ability of predatory mite Neoseiulus californicus (McGregor) to Polyphagotarsonemus latus (Banks), a polyphagous pest mite damaging various crops, the predations of N. californicus on different stages of P. latus were examined by using the functional response method under conditions of five temperatures (19, 22, 25, 28 and 31℃) and RH (75±5)% in the laboratory. The results showed that the selective coefficient Q of the predator on eggs, larvae, nymphs and adult females were 0.64, 1.50, 0.77 and 1.09, respectively. The functional responses of N. californicus fitted well with Holling Ⅱ type at different temperature conditions, and it preferred T. latus larvae and female adults much more than the eggs and the nymphs. The predation ability of N. californicus on T. latus was the strongest at 28℃. The attack coefficients on the eggs, larvae, nymphs and adult females were 0.45, 0.97, 0.79 and 0.82, respectively, and the maximum daily predation numbers were 27.10, 71.94, 32.79 and 35.21, respectively. The predation function of N. californicus had strong intraspecific interference, and predation rates decreased with rising predator densities. At 28℃, the relationship between the predation rate and its own density was E=0.4345P-0.6278. The results indicated that N. californicus had great potential for controlling the pest mite P. latus. |
