摘要
通过对武汉地区桃园梨小食心虫(Grapholita molesta Busck)发生动态的调查,明确了梨小食心虫在武汉地区的发生规律及其习性。结果表明,梨小食心虫在武汉地区1年发生4代,世代重叠现象较严重,特别是第二代与第三代、第三代与第四代,各世代间没有明显的界限。该研究为梨小食心虫的科学防治提供了理论依据。
The occurring dynamic of Grapholita molesta Busck in peach orchard in Wuhan was investigated to reveal the occurring regularity and habits of G.molesta in Wuhan.Results showed that there were four generations of G.molesta in Wuhan occurring in 1 year.The phenomenon of overlapping generations was serious,especially between the second and the third generation or between the third and the fourth generation.There was no obvious boundary between different generations.The research provided the theoretical basis for the scientific control of G.molesta.
