摘要: 用罩笼试验方法,研究了褐飞虱和白背飞虱若虫间的互作关系。结果表明,两种飞虱若虫间存在程度不同的相互作用过程。褐飞虱或白背飞虱的羽化、性别、翅型、雌虫体长和体重等生物学特性的表现都受到来自异种飞虱存在的影响。随褐飞虱比例的增加,白背飞虱的上述反应愈趋明显;反之,随白背飞虱比例的增加,褐飞虱则少有这种变化。种间密度制约效应远大于种内密度制约效应,表明两种飞虱诸种生物学特性对种间作用的反应存在着差异。

Abstract: Nylon net method was used to study the interactive effect between Nilaparvata lugens and Sogatella furcifera nymphae. The result shows that an interactive process was existed in different degrees between these two kinds of nympha. The expression of biological characteristics of the two planthoppers, such as emergence, sex, wing form, female's body length and weight, was affected in some degrees by the existence of each other. With an increasing proportion of N. lugens, the expression mentioned above of S. furcifera became more obvious, and vice versa, that of N. lugens was little. The effect of interspecific density was far greater than that of intraspecies, indicating that there existed a difference to the interspecific reaction between the biological characteristics of the two planthoppers.
