摘    要:通过田间系统调查和鉴定,明确了宁夏苜蓿害虫天敌种类和优势种群,初步研究了优势种群瓢虫、草蛉、捕食蝽及蜘蛛的田间消长规律,并对主要害虫蚜虫、蓟马与其天敌的动态关系进行了分析,为今后苜蓿害虫的生物防治提供了重要的科学依据。

关 键 词:宁夏  苜蓿害虫  天敌  种类  田间发生规律  生物防治

Abstract:The predator species and dominant populations of alfalfa insects were determined in Ningxia, through systematic field investigations and species identification Field growth and decline of dominant species such as ladybeetles, lacewings, predatory bugs and spiders was preliminarily studied, and the dynamic relationship between alfalfa aphids, thrips and the dominant predators was analyzed as well, which provided vital scientific basis for future biological control of alfalfa insects
Keywords:alfalfa insects  predators  occurrence regulation
