食心虫预测预报研究进展

食心虫类害虫是我国北方多种果树上的主要害虫,一般世代周期长、隐蔽性强,在不同寄主上成虫发生期、幼虫蛀果期、果内生活时间,甚至发生世代数均存在差异,特别是越冬幼虫出土习性各异,生产上测报及防治难度较大。以桃小、梨小食心虫为例,阐述了食心虫类害虫测报技术方面的研究进展,旨在为食心虫的准确测报及防治提供新的思路与参考。

Review of Forecasting of the Borer Pests

The pests of the borer class are the major pests in varieties of fruit trees in northern China. In general they are of long generation, strong concealment and there is difference in adult pest occurance, young pest fruit eating, in-fruit living and occurance generation number, especially in over-winter young pest earth emergence habit when live on various host trees, so it is very difficult to forecast and control. This paper, taking Grapholitha molesta Busck and Carposina sasakii Matsmura as example ,described the research progress of forecasting technology and offered newideas and references on accurately forecasting and control-ling of borers.
