摘要：利用黑光灯、性诱剂诱集及田间调查的方法对河北省两个注册梨园主要害虫及其消长规律进行了调查研究。结果如下，两个注册梨园共计采集到主要害虫25种，隶属4目15科。对5种主要害虫成虫消长规律的研究表明，桃小食心虫 Carposina niponensis Walsingham全年消长呈现两个明显的高峰，表现出2代类型区的特征。梨小食心虫Grapholitha molesta (Busck) 消长全年呈现四个明显的高峰；铜绿丽金龟 Anomala corpulenta Motschulsky和暗黑鳃金龟 Holotrichia parallela Motschulsky一年一代，成虫发生期分别集中在6月下旬至7月下旬和7月上旬到8月中旬；茶翅蝽Halyomorpha picus Fabricius危害盛期发生在6月下旬至8月中旬。

Abstract:

Abstract: By means of black light lamp, sex attractants and field investigation, 25 species of pear insect pests that belong to 4 orders and 15 families in two registered export pear orchards in Hebei Province were invstigated. Occurrence regularity of 5 species major pear pests adults were studied and analyzed. The results showed that C. niponensis Walsingham had two obvious population peaks in one growing season, and occurred two generations in one year. G.molesta (Busck) had four population peaks. The population peak of A.corpulenta Motschulsky and H. parallela Motschulsky occurred from late in June to late in July and from early in July to the mid- August separately. The population peak of H. picus Fabricius occurred from late in June to the mid-August. Key words: registered export pear orchard；Pests species；Occurrence Regularity
