| 摘 要： | 本文利用Taylor幂法则和Iwao回归法对稻水象甲LissorhoptrusoryzophilusKuschel卵的空间分布型进行了测定 ,结果表明稻水象甲卵在田间呈聚集分布 ,且符合负二项分布 ,k值为 0 4 796。其种群聚集主要是由环境因子引起的。应用Iwao的抽样模型建立了稻水象甲卵的田间理论抽样数公式 :N =1D2 1 784 6M + 0 2 4 2 5 。并根据Gerrard的零频率模型建立了估计该种群平均密度的零频率模型 :X =1 5 787( -lnP0 ) 1 0 62 5。

| Abstract: | Taylor's power law and Iwao's distribution function were used to analyze the spatial distribution pattern of the egg of the rice water weevil (RWW), Lissorhoptrus oryzophilus Kuschel. The results indicated that the pattern of the RWW eggs in field fit the negative binomial series (k=0^4796).The aggregation of eggs is due to some environmental effects.The formula of optimum theortical sampling number, which based on Iwao's method is: N=1D+21^7846M+0^2425. The mean density of the RWW eggs was estimated using the zero frequency model based on the Gerrare's method as X=1.5787(-lnP 0) 1.0625. |
