论蔬菜种植布局与小菜蛾发生为害的关系

STUDY ON THE DIAMONDBACK MOTH,PIUTELLA XYLOSELLA RESPONES TO VEGETABLE COMMUNITY TEXTURE

本文从化学生态学的角度论述了菜地的设置、蔬菜种植密度、品种、菜龄的种植布局等与小菜蛾转移为害的关系,掌握小菜蛾的转移为害规律,是防治这种害虫的重要基础,并可为设计一个合理的菜田蔬菜群落结构提供理论依据。

The imterations between artificial vegetable community texture and the searching behavior of the dia-mondback moth (DBM),Plutella xylocella were discussed with chemical ecology association in this paper.The texture implies the individual crucifers density,dispersion,and species richness.An understanding of DBM searching mechanism may be used in current DBM management practice to disign agricultural systems that are less likely to be attacked by this pest.
