Preliminary Study on Spatial Distribution Pattern of Endoclyta signifer Walker Larva
摘要
Abstract
[ Abstract ] The paper was to study the spatial distribution of Endoclyta signifer Walker Larva. [ Method ] The larvae distribution in Eucalyptus plantation in Beiliu and Luchuan counties of Guangxi province were investigated. Ten standard plots were set ,and the spatial distribution pattern of E. signifer larva was confirmed using six different aggregation indices and regression analysis. [ Result ] The larvae mainly distributed in the base of trunk lower than 1 m,and its spatial distribution pattern was mainly aggregative distribution,which was caused by the environmental factors. The optimum sampling formula of E. signifer larva under different population densities was n = t2 ( 1.1/m + 0. 674 4)/D2,and limited decision-making sequential sampling model was T′0(n),T″0(n) = n ± 1.332√(n)( m0 = 1 ). [ Conclusion] The result provided scientific basis for sampling and forecasting of E. signifier.关键词
