摘要
朱砂叶螨是为害棉花的重要害螨之一,本文对23块棉由朱砂叶螨在棉苗中空间分布型的调查研究结果表明,朱砂叶螨在棉田呈聚集分布.此外还进一步探讨了序贯抽样在朱砂叶螨防治中的应用,建立了序贯抽样方程式及序贯抽样表.
The carmine spider mite is one of the important pest insect of cotton field in Henan province. Based on the analyses of 23 samples selected from cotton field in 1988, the spatial distribution pattern of mite is investigationed. The results shows that thermite trends aggregation, and the role of seguential sampling for the pourpose of the mite mangement also is studied in this paper.
