| 中文摘要: |
| 1997～ 1999年 ,在安徽省广德县应用性诱剂对越冬代二化螟进行了较大面积的迷向防治试验。结果表明 ,田间放置诱芯150～750个/hm2的迷向率为71.1%～80.7% ;每公顷放置诱芯750、300～375、120～150个和 30个的迷向区卵量比对照区分别下降79.4%～86.1%、72.9%～84.7%、58.3%～65.1%和58.9% ;每公顷放置60个诱芯的大面积迷向示范区中稻秧田和早稻大田卵块量分别比对照下降 82.4%和73.2% ,早稻大田枯鞘丛率比对照下降70.4%。应用性诱剂迷向防治二化螟 ,方法简便 ,成本低 ,无公害 ,可望成为目前单季稻区6月底前不用或少用农药且能控制第一代二化螟危害的有效方法 |

| Field experiments on mating disruption effects on the rice stem borer, Chilo suppressalis (Walker), with synthetic sex pheromone were conducted in Guangde County, Anhui Province in 1997-1999. The results showed that the rate of mating disruption was 71.1%-80.7% caused by 150-750 rubber pheromone dispersers per hm 2. The egg numbers were reduced by 79.4%-86.1%, 72.9%-84.7%, 58.3%-65.1% and 58 9% at the treatments of 750, 300-375, 120-150 and 30 rubber dispersers per hm 2, respectively. In large scale disruption demonstrations, numbers of egg masses decreased 82.4% and 73.2% at placements of 60 dispersers per hm 2 in mid season rice seeding paddy and in early season transplanting paddy, respectively. The infested leaf sheaths were reduced by 70.4% in the above transplanting paddy. The authors believe that this disruption technique is easy, cheap and safe, thereby, promising in control of the lst generation of the pest with little or no insecticide in the rice area in early season |
