| 摘 要： | 为明确性信息素缓释剂防治梨小食心虫的持效期及合理使用密度,我们于2008、2009年在河南省郑州市对每根应用0.24 g梨小食心虫性信息素丝迷向防治桃园梨小食心虫进行了试验。结果表明,在梨小食心虫越冬代活动前以350、500、650根·hm-2处理,处理后5个月内均保持了较好的防治效果;350根·hm-2处理在8月份以后防效迅速降低,密度较高处理则保持相对较好防效。结合防治成本,建议中早熟品种可使用350根·hm-2密度进行处理,晚熟品种使用500根·hm-2以上密度处理。

| Abstract: | To explicit the efficacy,efficacy duration and reasonable use density of sex pheromone dispenser in controlling oriental fruit moth(OFM),Grapholitha molesta(Busck),0.24 g per bar sex pheromone at different densities was dispensed to mating disruption of OFM in peach orchard at Zhengzhou,Henan,during 2008 to 2009.The results show that dispenser applied before 1st adult emergence had excellent control effect during 5 months and there were no significant differences among treatments.The control effect declined rapidly in the treatment of 350 bar per ha compared with the 500 bars per ha,650 bars per ha after August.It is suggested that 350 bars per ha dispensers were applied to control OFM in mid-early maturity peach varieties and 500 bars per ha or higher density were needed to control OFM in late maturity peach varieties. |
