近年来,随着“绿色有机”烟草的提出,生物防治是烟草病虫害防治的大势所趋,烟蚜茧蜂防治烟蚜不断被推广,防治面积不断增大,研究一套适合当地的烟蚜茧蜂防治烟蚜技术显得特别重要。2010年,隆阳区开始饲养烟蚜茧蜂,种蜂、种蚜来源于大理州烟草公司,为确保足够的种源,2011年,隆阳区开始尝试烟蚜茧蜂越冬保种,经过1 a的艰辛努力,隆阳区保种工作取得了一定成效。基于此,对烟蚜茧蜂保种技术进行总结,旨在保山烟草能有自己独特的保种技术,为保山烟蚜茧蜂的推广技术具有一定的指导意义。
In recent years, with the “green organic” tobacco put forward, biological control is the general trend of tobacco pest control, tobacco aphid Aphis gossypii has been continuously promoted, increasing control area, to study a set of suitable for the local tobacco aphid cocoon Bees aphid control technology is particularly important. In 2010, Longyang District began to raise tobacco aphid Braconian bee, species of bee, the kind of aphid originated from Dali tobacco company, in order to ensure adequate provenance, in 2011, Longyang District began to try tobacco aphid parasitoids overwintering conservation, after 1 a hard work, Longyang preservation work has achieved some success. Based on this, we summarize the technique of preserving the tobacco aphid Braconidae, aiming that Baoshan tobacco can have its own unique technology of preserving the seed, which is of guiding significance for the popularization of the technology.
