防止已包装的烟草受害虫侵袭,对维护贮存烟叶的价值是必需的。现行商业上的防治害虫熏蒸法,尽管可以解决问题,但存在某些不利方面。以集装箱装运从美国出口的烟叶通常要在海运之前进行七天的熏蒸——这是对害虫充分熏蒸及集装箱通风散毒所需时间的安排。在贸易环节中这一时间间断的费用以及在常规熏蒸中所用化学制剂的毒性,促使科研工作者探讨另外的害虫防治方法。 Preventing the packaged tobacco from infestation by pests is necessary to maintain the value of stored tobacco. The current commercial control of pest fumigation, although it can solve the problem, but there are some disadvantages. Flue-cured tobacco exported from the United States in container shipping usually has to be fumigated for seven days before shipping - an arrangement that takes time to adequately fumigate the pests and disperse the containers. This time-consuming cost of trade and the toxicity of chemicals used in conventional fumigation have prompted researchers to explore additional approaches to pest control.
