| 摘 要： | 菸潛叶蛾 (卽馬鈴薯块茎蛾) 在云南普遍为害烟草。在云南南部温度較高地区,还有一种菸草瘿蛾严重为害,菸草幼茎受害后形成虫瘿或成畸形;受害烟苗往往死去。菸草瘿蛾在大田为害侧芽及菸株髓部。本文記述了这两种菸草害虫的为害性及习性。菸潛叶蛾在昆明一年发生4—5代,世代重叠;在室外温暖向阳处可終年活动,在室內飼养則以蛹过冬。菸草瘿蛾在南部建水县羊街埧,一年至少发生4代。菸潛叶蛾喜温暖干燥的气候,栽培管理与环境条件对菸草瘿蛾发生有密切关系。历年調查,在半山坡烟田,土壤干燥处, 虫害严重;苗床水分充足,土壤經常保持湿潤,則很少发生。此外,与土壤、前作都有关系。彻底处理菸草残株,消灭其越冬場所是減少或消灭这两种害虫的主要措施。菸潛叶蛾一般为害脚叶,在大田生长期打脚叶是有效措施。貫彻馬鈴薯的检疫和防治措施,也关系到菸草上为害的輕重。疫区調运种薯,特别是調至菸草种植地区,必須严格检疫。

| Abstract: | The tobacco leaf miner (i.e. potato tuber moth, Gnorimoschema operculella (Zeller)) is widely distributed in the tobacco growing districts of Yunnan Province and is one of the worst pests of the tobacco plant. In Southern Yunnan where the temperature is comparatively higher, there is another serious pest of tobacco, the tobacco stem borer (Gnorimoschema heliopa (Lower)). At seedling stage, the affected young stems are stimulated to produce galls or develop into abnormal growth. Finally, the affected seedlings wilt and die off. Not only in the seed bed, but also in the field, tobacco stem borers attack the lateral buds or pith of the tobacco plant. In Kunming, the tobacco leaf miner has four or five overlapping generations. Winter is passed as pupa in the laboratory, but feeding and breeding may be continuous in the exposed warmer place. In Southern Yunnan such as Yangjiaba, Jianshui, the tobacco stem borer has more than four generations a year. The tobacco leaf miner is adopted to warm and arid climate. The occurrence of the tobacco stem borer is closely related with the field management and the environmental conditions. Investigations in the past years have shown that the pest is most serious in the hillside tobacco plots where the soil is very arid, but scarcely occurs when the seedling bed is supplied with sufficient water and the soil is kept humid. Infestations may be prevented by destroying all the tobacco stubbles during winter. To gather and burn up the leaves of the under part of the tobacco plant is an effective control measure against the tobacco leaf miner. Strict quarantine measures against the potato tuber moth should be maintained to prevent its spread. |
