远洋船舶的特点是装载量大,配载情况复杂,使用年限长,穿洋过海,航程达五大洲。正因如此,远洋船舶成为传播昆虫的媒介,潜藏有极大的危险。加以船体结构特殊,残存于货仓之内和缝隙之中的谷物,动物饲料及其他的农付产品难以彻底清除干净。害虫一旦感染到船上之后,则可因食物丰富而得以生存、繁殖、发展、扩大和蔓延。正由于有这些原因,我们才先后在装载钢材的西德籍“保罗利克麦”轮上截获到危险性害虫肾斑皮蠹;巴拿马籍“白海”轮上发现了对外检疫对象谷斑皮蠹等。仅据不完全的统计:
The characteristics of ocean-going vessels are large loading capacity, complicated loading conditions, long service life, crossing the ocean across the sea and reaching five continents. Because of this, ocean-going ships have become a media for transmitting insects and are potentially dangerous. It is difficult to completely remove grains, animal feed and other agricultural products that have special hull structure and remain in the crevices and crevices. Once the pest infects the ship, it can survive, reproduce, develop, expand and spread due to abundant food. It is for these reasons that we have intercepted the dangerous pest nephrops on the Western German “Paul Lick Mai” wheel loaded with steel; the foreign quarantine objects found on the Panamanian “White Sea” Guppy pest and so on.
