摘要: 杨始叶螨Eotetranychus populi(Koch)是危害杨柳科植物的重要害螨。本文研究了该螨的主要生物学特性和有效积温。结果表明:在16℃一28℃范围内,该螨的发育历期随温度升高而缩短,反之则延长。经测定,卵的发育起点为(8.77±0.83)℃,有效积温为(100.0±5.96)日度; 幼螨至成螨的发育起点为(9.64±1.60)℃,有效积温为113.3±13.88)日度;全世代的发育起点为(8.67±0.92)℃,有效积温为(2182±14.37)日度。同时还观察了该螨在不同温度下的产卵进度、单雌产卵量、寿命和交配活动等。

Abstract: Eotetranychus populi (Koch) is an important mite pest of Salicaceae in North China. The principal biological characteristics and the effective accumulated temperature were studied. The results showed that the duration of development stage was negatively correlated with temperature ranging from 16 to 28℃. It was foundthat the developmental zero of egg was (8.77±0.83)℃ and the effective accumulated temperature of the egg stage was 100.0±5.96 day-degree. The developmental zero from larva to adults was 9.64±1.60℃ and the effective accumulated temperature from larva to adults was 113.3±13.88 day-degree. The developmental zero for whole generation was (8.67±0.92)℃ and the effective accumulated temperature of wholegeneration was 218.2±14.37 day-degree. In addition, process of laying eggs, egg number one female, the longevity and mating at different temperature were studied.
