| Abstract: | Yu Xiulin and Ren Chaozuo(l986) have further improved Iwao's m*-m model and concluded that the Further Improved Iwao's m*-m model is more generalized, i.e. the Iwao's model and Xu Rumei et al. (1984). Improved Iwao's model are the special cases of the model. In this paper Lhe Further Improved Iwao's Model is applied to the sampling technique of insect populations, a set of new sampling models are advanced. |
