“盖将开物以成务,必先分类而知名。” 农业、林业、粮食、毛纺工业、交通、外贸、卫生、国防,经常出现害虫新问题,要求鉴定其种类。过去几年在农业害虫防治、测报及天敌利用上,投入人力、费用很大,虽然取得很大的成绩,但还须进一步提高,特别是在摸清种类和掌握规律方面。可以这样说:有效的测报与防治建立在正确的生活规律上,而正确的生活规律的掌握,必须以正确的分类鉴定为基础。所以昆虫分类工作是国家昆虫科学水平的重要标志。 “Cover will be opened to serve, must first classification and well-known.” Agriculture, forestry, grain, wool industry, transportation, foreign trade, health, national defense, pests often new problems, requiring identification of their species. Over the past few years, it has been very costly to invest manpower in agricultural pest control, metrology reporting and natural enemies utilization. Although great achievements have been made, it needs to be further improved, especially in terms of understanding the types and mastering laws. It can be said: effective newspaper and prevention based on the correct law of life, and the correct grasp of the law of life, must be based on the correct classification and identification. Therefore, the classification of insects is an important symbol of the national level of insect science.
