一、前言我省地形复杂,气候差异较大,树种资源丰富,昆虫种类繁多,其中有不少种类对林业生产曾产生过严重危害。过去由于对我省森林昆虫种类缺乏调查研究,因而不可能制订出各种相应的预防措施,对有关虫害的防治始终处于被动局面,给林业生产带来一定的损失。为了变被动为主动,给生产、科研规划提出依据,更好地同“病虫害作斗争”,必须摸清我省森林昆虫种类。我们自一九七八年开始进行了森林昆虫种类的普查工作,通过近半年的外业
I. Preface Our province has complex topography, large climatic differences, abundant tree species resources and a great variety of insects. Many of them have had serious harms on forestry production. In the past, due to the lack of investigation and study on the species of forest insects in our province, it was impossible to formulate various corresponding preventive measures. The prevention and control of pests were always in a passive situation, which brought some losses to forestry production. In order to become passive and proactive, to provide a basis for production and scientific research planning and to better combat “pests and diseases”, we must find out the types of forest insects in our province. Since 1978, we have conducted a census of the forest insect species. Through nearly half a year of overseas operations
