蠊螯螨对番茄刺皮瘿螨的捕食作用研究(英文)

[Objective] The paper was to study the predatory capacity of different states of Homeopronematus anconai and its female adult mite against different states of Aculops lycopersici, so as to provide scientific basis fur effective application of H. anconai against the damage caused by A. lycopersici. [ Method ] The predatory capacity of deutonymph, male adult mite and female adult mite of H. anconai against nymph of A. lycopersici, as well as the predatory capacity of female adult mite of H. anconai against eggs, young nymph mites and adult mites of A. lycopersici were determined in rearing room under certain temperature and humidity conditions. [ Result ] The predatory functional response curve of deutonymph, male adult mite and female adult mite of H. anconai against nymph of A. lycopersici was Holling Ⅲ under the conditions of T = （25 ± 0.5 ） ℃ and RH = 70% ± 5%. The attack coefficients were 0.241 6, 0. 357 1 and 0. 509 6, while the treatment times were 0. 064 5, 0. 036 7 and 0. 014 1, respectively. The attack coefficient of female adult mite of H. anconai was the largest with the shortest treatment time. The predatory functional response curve of female adult of H. anconai against eggs, young nymph mites and adult mites of A. lycopersici was also Holling Ⅲ. The attack coefficients were 0.357 3, 0. 509 6 and 0.204 1, while the treatment times were 0. 011 6, 0. 014 1 and 0. 087 6, respectively. [ Conduslon ] The female adult of H. anconai had the strongest predatory capacity against A. lycopersici.

蠊螯螨对番茄刺皮瘿螨的捕食作用研究

[目的]研究蠊螯螨不同螨态和蠊螯螨雌成螨对不同螨态番茄刺皮瘿螨的捕食能力,为有效应用蠊螯螨控制番茄刺皮瘿螨危害提供科学依据。[方法]在一定的温湿度条件下,在饲养小室内测定蠊螯螨的第2若螨、雄成螨和雌成螨对番茄刺皮瘿螨若螨的捕食能力和蠊螯螨雌成螨对番茄刺皮瘿螨卵、幼若螨和成螨的捕食能力。[结果]在T=(25±0.5)℃、RH=70%±5%的条件下,蠊螯螨的第2若螨、雄成螨和雌成螨对番茄刺皮瘿螨若螨的捕食功能反应曲线均为HollingⅢ型,攻击系数分别为0.241 6、0.357 1、0.509 6,处理时间分别为0.064 5、0.036 7、0.014 1,均以蠊螯螨的雌成螨攻击系数最大,处理时间最短;蠊螯螨雌成螨对番茄刺皮瘿螨卵、幼若螨和成螨的捕食功能反应曲线也均为HollingⅢ型,攻击系数分别为0.357 3、0.509 6、0.204 1,处理时间分别为0.011 6、0.014 1、0.087 6。[结论]蠊螯螨雌成螨对番茄刺皮瘿螨若螨的捕食能力最强。
