| 中文摘要: |
| 蚜虫对金黄色具有正趋性,对银灰色具有负趋性。利用蚜虫的负趋性,设置一定银灰色标志,能起到驱避蚜虫的作用。连续4a对旱地油菜蚜虫试用银粉带进行防蚜研究,结果表明:银灰色标志制作简单,使用方便,成本低廉,能有效地控制旱地蚜虫及其传播的病毒病,增产作用显著,值得推广。 |
| 英文摘要: |
| The aphid possess positive taxis to golden and negative taxis to silver grey. If certain silver grey mark is set up, it can plan an important role in driving aphid. This paper uses the silver powder belt to the rape aphid in dry-land for four years. The results indicate that silver grey mark is very simple in setting and very convenient in using. The cost is very low. It can control the aphid in dry-land and the virosis were spreaded by aphid effectively. The effects of increasing in production is remarkable. It is worth spreading in production. |
