沿海地区木麻黄毒蛾幼虫种群结构及空间格局研究

Spatial Patterns and Sampling Techniques of Larvae of Casuarina equisetifolia larvae in Coastal Areas

应用昆虫空间格局分析法对福建沿海地区东山岛木麻黄毒蛾幼虫在木麻黄林间的空间格局进行了调查分析。结果表明,木麻黄毒蛾幼虫在林间呈聚集分布,由它的生物学特性与环境的差异性因素综合影响所致。应用抽样技术模型,研究了林间调查的理论抽样数,为提高虫情调查及预测预报的准确率提供理论依据。

The spatial pattern of Casuarina equisetifolia larvae on Dongshan Island of Fujian was investigated by using insect spatial pattern analysis. The results showed that the larvae of Casuarina equisetifolia were clustered in forest,which was caused by the biological characteristics and the diversity of environment. At the same time,the theoretical sampling number of forest investigation was studied by using the sampling technique model. The theoretical basis for the investigation and prediction accuracy of pests was not provided.
