摘要: |
广西白蜡生产失败的主要原因是,首先,年降雨量超过1552mm,间接或直接地引起大批白蜡虫死亡;其次,对白蜡虫具有毁灭性的白蜡虫寄生蜂不采取任何防治措施,致使种虫寄生率高达92.9%。因此,白蜡生产遭受失败。广西气候多种多样,年降雨量、在1552mm以下有22个县,发展白蜡生产是有潜力的,可逐步恢复和发展白蜡生产。 |

Abstract: |
The causes that result in failure of production of white wax in Guangxi are, firstly, overmuch annual rainfall (above 1 552 mm), the rainfail upper limit is about 1 552.5 mm, under the limit, the production would be successful; secondly, the parasitic bee of white wax scale had not been controled, with the result that the parasitic rate to the seed insects is up to 92.9%. But,in Guangxi there are 22 counties where the annual rainfall is less than 1552.5 mm, the white wax production would be resume and develop gradually. |
Key words: white wax production white wax scale annual rainfall parasitic bee |
