| 摘 要： | 本文根据1987～1989年田间抽样调查和化学药剂防治试验结果,在以往分布型研究的基础上推导出根据多样本植株累积受害率和累积受害株数确定果园苹掌舟蛾实际防治指标的预测预报数学模型及其相应的实用图表。并筛选出防治该害虫的高效化学药剂。旨在为苹掌舟蛾的测报和化学防治积累资料,提供依据。 |

| Abstract: | Field investigation and chemical pesticide control experiment was made at the orchards of Jilin Agricultural University during 1987-1989 to establish a mathmatical model for the prediction of phalea flavenscens (Bremer et Grey)and to screen highly effective pesticides for the control. On the basis of the investigation, an improved Iwao Sequential Sampling Formular was proposed to be used in determining the critical stage i'or the control according to the number of plants damaged by the pest in mult'svnpl.33. This mathmatieat model, closely related to chemical control, was found effective in practice and can be put into use in orchard production. |
