去年年底,上海一些单位在使用从美国进口的花旗松(Douglas Fir)原木时,发现较多钻蛀在木材内部的小蠢虫。为此,采取各种措施,进行了杀虫处理,其中有些是试验性的。我们参加了这一工作,现将情况介绍如下。各处理过程中所用试验材料大致有以下四类: A、塑料管加塑料盖,两端戳针孔,内装适从美国花旗松原木中检出的害虫。 B、同上虫样管,内装人工饲养的赤拟谷盗成虫等。 At the end of last year, some units in Shanghai, using logs imported from the United States, Douglas Fir, found more stinkbugs in the wood. To this end, various measures have been taken to kill insects, some of which are experimental. We participated in this work, the situation is as follows. Test materials used in the process generally have the following four categories: A, plastic tube plus plastic cover, pinhole at both ends, built-in suitable for detection of pests in American Douglas fir logs. B, the same as the worm-like tube, built-artificial breeding of red tarragon adults and so on.
