摘要/Abstract

摘要： 研究了褐飞虱和白背飞虱混合种群的取食为害对水稻营养生长的影响.结果表明,两种飞虱的成虫干重、水稻叶面积和其地上部干重因虫口密度的增加而下降,变化幅度与种间数量组合有关;水稻比叶重随为害程度的加重而加大;在褐飞虱与白背飞虱种间以1:3、2:2和3:1比例的3种组合处理中,虫体总干重(X)与稻株地上部损失量(Y)之间存在着极显著的线性关系,线性方程分别是Y=69.17+30.43X、Y=172.48+36.51X和Y=87.59+37.67X,b值相应为30.43、36.51和37.67.

Abstract: Studies on the impact of feeding damage of mixed populations of Nilaparvata lugens and Sogatella furcifera on vegetative growth of rice plants show that the dry weight of the adults of two planthoppers and the leaf area of rice plants and their shoot dry weight were decreased with increasing nymph density, and the range of the variations was related with interspecific proportion in quantity. The ratio of dry weight to leaf area of rice plants was increased with increasing damage. Avery significant linear relationship was observed between the total dry weight of the mixed populations(X) and the loss of shoot dry weight of rice plants(Y) in three treatments (1:3,2:2,3:1) of quantitative proportion of N.lugens to S.furcifera, which is Y=67.17+30.43X, Y=172.48+36.51X and Y=87.59+37.67X, and relevant b values were 30.43, 36.51 and 37.67, respectively.
