测定白背飞虱各虫态的抗寒性,从理论上研究飞虱越冬,发生规律和预测预报有重要参考意义。目前对稻飞虱的两种优势种白背飞虱和褐飞虱在贵州省的越冬情况,主害代的虫源性质等测报的主要依据,还有争论,为了科学地研究白背飞虱的生态特征,认识事物的本质,观察白背飞虱各虫态在不同温度下的反应,以便结合长期气候资料和其他因素进行分析,探索稻飞虱在贵州省越冬的可能性及其规律,寻求抗寒指标,为联合测报工作提供必要的数据,我们于1982年8月～11月对白背飞虱的抗寒能力进行了测定,初报如下。
To determine the cold resistance of the whitebacked planthoppers, it is important to study the overwintering, occurrence regularity and prediction of planthoppers in theory. At present, the dominant basis of the two dominant species of planthopper, Sogatella furcifera and Nilaparvata lugens, is overwintering in Guizhou Province and the nature of the insect pests of the main pests. In order to scientifically study the ecology of Sogatella furcifera Characteristics and understanding of the nature of things to observe the whitebacked planthopper responses at different temperatures in order to combine the long-term climatic data and other factors to analyze the possibility of planthopper overwintering in Guizhou Province and its laws, seeking resistance Cold indicators, to provide the necessary data for joint survey work, we in August 1982 ~ November cold-resistant whitebacked planthopper were measured, the first report is as follows.
