摘要
对陕西不同地区苹果园天敌昆虫进行了调查研究,通过野外调查与采集标本,室内分类鉴定,明确了不同地区天敌昆虫资源,研究结果还表明,天敌昆虫在陕西不同地区的苹果园的分布存在一定的差异,随着苹果园海拔高度的升高,果园天敌昆虫的种群及数量分布有逐渐减低的趋势,天敌昆虫的分布不仅与自然地理条件、植被等因素直接有关,而且与管理等人为影响有较大的关系。
Resources of natural enemy insects in apple orchards were systematically studied in apple orchards in Shaanxi province. The results showed that： the distributions of natural enemy insects were different from the apple orchards in different altitude. It is a tendency of decrease to the population and number distribution of them when the altitude is increased. The distributions of them related to many cause which included their geography, vegetation and men＇s intervention.
