烟蚜茧蜂防治烟蚜对烟叶质量的影响--以楚雄彝族自治州牟定县新桥镇为例

摘要

Objective] The aim was to explore effects of Aphidius gifuensis on quality of tobacco leaf.[Method] According to the climate envi-ronment and production conditions of fields in Xinqiao town of Mouding, Chongxiong in 2012, the cost, surface feature, chemical compositions and smoking evaluation of tobacco leaves obtained from the fields in the presence and absence of Aphidius gifuensis as well as under general con-trol were studied and compared.[Result] The tobacco leaves under Aphidius gifuensis were easy to be dried and in high quality.It was found the weight of a single leaf could reach up to 8.6 g, production yield up to 2 742.5 kg/hm2 and output of 50 875.00 Yuan/hm2 based on price aver-aged at 18.55 yuan/kg.Furthermore, the first-class tobacco leaves accounted for 53.10%.The tobacco leaves under Aphidius gifuensis control clearly showed better production yield and output, overall quality than those without Aphidius gifuensis control and general control.[Conclusion] The results provided theoretical basis for using Aphidius gifuensis to control Myzus persicae.%[目的]探讨烟蚜茧蜂对烟叶质量的影响。[方法]在云南省楚雄彝族自治州牟定县气候环境和生产条件下，比较烟蚜茧蜂释放区、常规防治区和空白对照区的经济性状、烟叶外观质量、化学成分和评吸质量。[结果]放蜂防治区的烟叶较易烘烤并且烤后黄烟率较高，单叶重高达8．6 g，产量高达2742．5 kg／hm2，产值高达50875．00元／hm2，均价18．55元／kg，上等烟比例为53．10％，烟叶产量、产值和总体质量明显较常规防治区和空白对照区好。[结论]试验结果为利用烟蚜茧蜂防治烟蚜提供了理论依据。
