- 摘要:
- 以梨小食心虫为试材，利用含性信息素的诱捕器对梨小食心虫雄蛾发生进行监测，同时对田间折梢率、蛀果率进行调查并记录当地有关气象数据，调查分析梨小食心虫雄蛾在大连地区的放生规律、幼虫的危害特点以及与梨小发生与气温和降雨的关系。结果表明：在大连地区梨小食心虫包括越冬代在内一年共发生5代；梨小食心虫各世代中，越冬代重点为害桃梢，第1代为害桃梢和果实，第2代主要为害早中熟品种及桃梢，第3代主要为害晚熟品种，少数为害桃梢；温度、降水量对梨小食心虫的生长发育、存活和繁殖有较大的影响。
- Abstract:
- Using oriental fruit moth as test material，the release rules of male oriental fruit moth，the hazard characteristics of larvae and the relationship with temperature and rainfall were investigated and analyzed in Dalian area.The male oriental fruit moth was survey by using the traps with sex pheromone，at the same time，the field fold shoot rate，fruit decay rate and recorded about the local meteorological data were investigated and recorded.The results showed that oriental fruit moth occured 5 generations of one year including overwintering generation in Dalian area.In each generation，overwintering generation damage in peach shoots，the first generation damaged in shoots and fruits of peach and of larvae，the second generation major damaged in the early maturing varieties and peach shoots，the third generation mainly damaged in the late maturing varieties hardly damaged in peach shoots；the temperature and precipitation had much more impact on the growth，development，survival and reproduction of oriental fruit moth.
