Wooden packaging materials made from unprocessed logs are usually of poor quality and have a high probability of carrying harmful organisms. Wooden packaging materials are often reused to carry different goods and transported to different regions, and the epidemics caused by them are also more complex. Once pests are introduced into a new area, due to the lack of effective control by natural enemies and the ability to escape the suppression of dominant species, it is easy to establish new populations, often causing more serious economic losses and ecological disasters than in their place of origin. Various examples show that wooden packaging materials and imported logs have become the main channels for the long-distance spread of harmful organisms (Qu, 1999). The invasion of long-distance beetles into the United States is the most famous case in recent years; in fact, pine wilt disease caused by pine wood nematode has been in the United States since 1983. After the discovery in Shimen Township, Taipei County, in less than 20 years, the disease has spread to almost all parts of Taiwan. Reports of the disease have been reported along the Zhongheng and Nanheng Highways. Even Kinmen and Matsu cannot escape the attack of the disease; the affected tree species have never been affected. Ryukyu pine and black pine, as well as Taiwanese two-leaf pine and slash pine, have plunged Taiwan's pine trees into unprecedented catastrophe; it is believed that pine wood threads invaded Taiwan through wooden packaging materials and beetles. The painful lessons of history are still there. Our country must abide by relevant international norms and strictly implement quarantine measures for imported and exported goods. Domestically, we can avoid the harmful organisms carried by imported goods that may cause irreparable disasters to Taiwan. Externally, we can reduce the number of export goods that are detected. It can also prevent domestic problems from turning into international problems.<\/p>","protected":false},"excerpt":{"rendered":"
