Biological invasion has become a most important concern to the world today, the relevant international organizations and scientists, even general public . Alien species invasion cause great harm and serious threat to the worldwide environment and economical development, and such negative effect is still gradually increasing. Base on the systematic taxonomy of the Curculionoidea of Coleoptera, we mainly focus on the identification, alert, quarantine and contral technique on invasive pests (insects). Curculionoidea is the largest group of Coleoptera, Insecta. At present more than 60,000 species have been described. List of entry plant quarantine pest of the People's Republic of China, declared on May 28, 2007, include 4 families, 20 genera and 27 species of Curculionoidea, which is a most important insect group in the quarantine work of our country and also a major component element in preventing alien invasive species. Currently our research group has kept the most of the collected specimen (150, 000) and named species (1, 300) of the weevil group in China. The named species exchanged from foreign countries for identifying and contrasting alien species, reach more than 600 species. The historical literature is rather plentiful and rich, accumulated by the famous weevil taxonomists Zhao Yangchang and Chen Yuanqing during 50 years or more. In recent years we mainly research are about important agricultural-forestry pest and some blank groups for complement. In the near 5-10 years we will continue the research works in this area. It will provide key reference for identifying important species in our country and for improving the world fauna research. On the other hand we will try our best to apply the serving of identifying the frequently encountering the Coleoptera weevil in plant quarantine and agro- forestry.
