虚伪钝绥螨是新近引进的一种抗有机磷杀虫剂的捕食性螨。经室内观察表明:湿度是影响该螨成活的重要因素,特别对卵的孵化影响更为明显。在恒温26℃,相对湿度43％条件下,卵的孵化率仅5.4％,而幼螨成活率达58.8％。观察还证明:湿度对卵孵化的影响,主要在于卵临近孵化期,如整个卵期处于低湿(43％)条件下,只要卵临近孵化期遇有适宜湿度,即可达到较高的孵化率。根据我国气候条件和虚伪钝绥螨对相对湿度的要求,作者认为我国主要苹果栽培区,可能适于该螨的生存。
False amblyseius is a newly introduced predatory mite resistant to organophosphate insecticides. The indoor observations show that: humidity is an important factor affecting the survival of mites, especially on the egg hatching more pronounced. Under the condition of constant temperature of 26 ℃ and relative humidity of 43%, the egg hatching rate was only 5.4%, while the young mite survival rate was 58.8%. Observation also shows that: humidity on egg hatching, mainly in the egg near the incubation period, such as the entire egg in a low humidity (43%) conditions, as long as the eggs near the incubation period when the appropriate humidity, you can achieve a higher hatchability. According to the climatic conditions in our country and the relative humidity requirements of the hypocritical Amblyseius mite, the author believes that the main apple cultivation area in China may be suitable for the survival of the mite.
