温度对加州新小绥螨捕食作用影响及高温耐饥饿能力研究

Effect of Temperature on Predation of Neoseiulus californicus (McGregor) and Starvation Tolerance at High Temperature

本文研究了在不同温度条件下加州新小绥螨Neoseiulus californicus(McGregor)对柑橘全爪螨Panonychus citri AaGregor的功能反应,以及研究了加州新小绥螨等5种捕食螨的高温耐饥饿能力。结果表明:在20～30℃温度下,随着温度的升高,加州新小绥螨对柑橘全爪螨各螨态的控制能力增强,在30℃时,控制能力最强,而超过30℃时,加州新小绥螨的控制能力下降;加州新小绥螨的高温耐饥饿能力显著高于江原钝绥螨Amblyseius eharai Amitai et Swirski和尼氏真绥螨Euseius nicholsi(Ehara et Lee),而与拟长毛钝绥螨A.pseudolongispinosus和真桑钝绥螨A.makuwa Ehara接近。

The functional responses of Neoseiulus californicus（McGregor） to Panonychus citri AaGregor at different temperatures and the starvation tolerance at high temperature of N.californicus and other four predatory mites were studied.The result showed that the controlling effect of N.californicus to P.citri AaGregor increased with the experimental temperature range of 20 to 30 ℃,the controlling effect was the strongest at 30 ℃,but when the temperatures was higher than 34 ℃,the controlling effect decreased;the starvation tolerance at high temperature of N.californicus was higher than that of Amblyseius eharai Amitai et Swirski and Euseius nicholsi,and closed to that of A.pseudolongispinosus and A.makuwa Ehara.
