摘要: 用笼罩试验方法,研究了褐飞虱和白背飞虱共栖时的互作效应.结果表明,在96h内,随时间的延长,2种飞虱对不同稻株的栖息率渐趋增加,最终达21.5~25.0%,不表现种间差异;脉冲试验使白背飞虱的雌性率和短翅率提高22.1%和398.1%;排除试验使白背飞虱的增殖、雌性率和雌虫短翅率各下降8.8%、20.8%和48.0%;种间作用对增殖.性比和翅型产生正的或负的效应.文中还讨论了种间作用存在的意义和方式.

Abstract: The interactive effects of Nilaparvata lugens and Sogatella furcifera in their commensality were studied with nylon net method. The results indicated that within 96 hours, the rest rates of these two kinds of insects on rice plants were gradually increased with time, finally reaching 21.5~25.0%, and there was no difference from each other. In pulse experiment, the female ratio and brachyptery of Sogatella furcifera were increased by 22.1 and 398.1%, and in removal experiment, the reproduction, female ratio and brachyptery of Sogatella furcifera were decreed by 8.8, 20.8 and 48.0%, respectively. Positive or negative effect of the interaction on reproduction, sex ratio and wing-form was observed and meaning and pattern of the interaction were also discussed in this paper.
