烟草甲是中药材、粮食和烟草仓库中一种主要害虫。关于此虫对粮食和烟草的危害情况,国内外已有一些研究,但对其在中药材仓库内的发生与危害则报导甚少。为了在中药材仓库内有效地防治烟草甲,作者于1986-1987年观察了此虫的生物学特性,现将研究结果报告如下。方法1986年7月,从中药材仓库采回烟草甲幼虫,在室温下用菊花作饲料在粗指形管内饲养,每管装一头幼虫,共100头,每2天观察一次化蛹、羽化情况。成虫羽化后按雌雄1:1配对单管饲养,逐日观察20对成虫的交配及产卵。然后在产卵始期、盛期和末期共取100粒卵置玻璃培养皿(φ5×1cm)中,每个培养皿内放一粒卵,每2天观察一次孵化进度。同时在盖有铜丝网盖的玻璃罐头瓶内群体饲养。各代均按上述方法进行,一直观察到1987年12
Tobacco A is a major pest in Chinese herbal medicines, grain and tobacco warehouses. About this pest to food and tobacco harm situation, there have been some studies at home and abroad, but its occurrence and harm in Chinese medicine warehouse is reported very little. In order to effectively control the tobacco A in the Chinese herbal medicine warehouse, the author observed the biological characteristics of this insect from 1986 to 1987, and the research results are reported as follows. Methods In July 1986, tobacco larvae were harvested from the Chinese herbal medicine storehouses. Chrysanthemum was used as feed for feeding larvae at room temperature. One larva was fitted in each tube for 100 larvae. The pupae and eclosion were observed every 2 days. Adult females were male and female mating 1: 1 single tube feeding, daily observation of 20 adult mating and spawning. Then a total of 100 egg-laying glass dishes (φ5 × 1 cm) were taken during the initial, peak and final stages of spawning. One egg was placed in each dish and the hatching progress was observed every 2 days. At the same time covered with a copper mesh lid canned glass bottle group feeding. All generations were conducted as described above, until 198712
