摘　　要：宝天曼自然保护区的森林害虫有6目51科245种(不包括蝶类、白蚁、蝗虫),并未达到成灾标准。保护区多年的气温、降水等小气候条件波动不大,为森林昆虫提供了稳定的气象条件;保护区森林生物多样性丰富,群落类型多样,群落多样性数值较高,森林群落稳定,维持了群落内昆虫类群的稳定。保护区森林中昆虫的多样化与天敌昆虫的存在,形成了复杂的食物网和食物链,是保护区森林害虫不成灾的主要原因。According to the preliminary investigation,forest pests belonging to 6 orders,51 families and 245 species have been found in Baotianman nature reserve(not including butterflies,termites,grasshoppers).The amount of the pest are not above the disaster standard.For many years,the air temperature,precipitation and other climatic conditions have small fluctuations in the reserve,which provide stable weather conditions for those forest insects.The forest in Baotianman nature reserve are rich in species diversity and community types,and the values of diversity of community is high.The stable forest ecology promotes the stability of group of insect.The diversity of insect in the forest forms complex food webs and food chain,and is the main reason to protect the reserve from insect disaster.
