| 摘 要： | 本文在发现域研究中首次提出了密比系数和域比系数的概念,解决了在自然条件下同一寄主的各种寄生蜂发现域比较的问题。研究和探讨了稻纵卷叶螟各种寄生蜂发现域之间的数值比较及寄生蜂密度对发现域的影响,建立了AR-DR对数回归模型。

| Abstract: | For the first time this paper presented the concepts on the coefficients of densities ratio, and the discovered area ratio applied in solving the problem on the comparison of discovery areas among the parasitie wasps parasitizing on the same host under the natural condition. In the discovered areas with various parasites of rice leaf-roller, the affectin caused by the parasitic population densities to its discovered area were investigated and compared. The model of AR-DR logarithm regression equation was also established. |
