河南烤烟栽培面积和总产量为全国首位,贮藏量也大。据调查,不论是仓库或露天烟垛贮藏,都发生 Epestia 属的小蛾类及烟草甲虫的为害。特别是上等优质烟,因含糖量高,经2-3年陈化处理进行自然发酵,贮藏期长,致受多种害虫混合发生的为害。经在郑州、新郑、许昌、开封、南阳等地调查,分布普遍。被蛀后烟叶穿孔、破碎,影响出丝率。而且虫粪、虫尸、丝网等污染,严重影响品质。常常成束烟叶全部吃光,仅留叶脉,失去使用价值。1982-1983年我们对烟草甲虫进行了研究,现将甲虫的研究结果报告如下:一、分布、为害烟草甲虫 Lasioderma serricorne(Fatric-ius),属鞘翅目 Coleoptera 窃蠹科 Anobidae,
Henan tobacco cultivation area and total output of the country’s first place, the storage capacity is also large. According to the investigation, both small moths and tobacco beetles of the genus Epestia have been harmed, either in storage or in open-air storage. Especially the finest quality tobacco, due to high sugar content, after 2-3 years of aging treatment of natural fermentation, long shelf life, caused by a variety of pests mixed damage. After the survey in Zhengzhou, Xinzheng, Xuchang, Kaifeng, Nanyang and other places, the distribution is widespread. After being eaten tobacco perforation, broken, affecting the silk rate. And insect manure, insect body, silk screen and other pollution, seriously affecting the quality. Often bunch of tobacco leaves are eaten, leaving only veins, loss of use value. From 1983 to 1983 we studied tobacco beetles. The results of the study on beetles are reported as follows: First, distribution and damage Tobacco beetle Lasioderma serricorne (Fatricus ius), Anobidae, Coleoptera,
