Parasitism of Overwintering Eggs of Apolygus lucorum by Telenomus sp. in Jujube Orchard

doi:10.16409/j.cnki.2095-039x.2016.03.002

Abstract

Abstract: A parasitoid, found in overwintering eggs of Apolygus lucorum in jujube orchard of northern China, was identified as Telenomus sp. according to morphological features. Direct observation showed a parasitism rate of 0.67%-1.25%, while molecular detection through species-specific primers developed for Telenomus sp. revealed a much higher parasitism rate of 13.04%-23.91% of the overwintering eggs. Compared with direct observation, PCR-based method is a more accurate method for assessing egg parasitism in A. lucorum by Telenomus sp..

Key words: Apolygus lucorum, Telenomus sp., jujube orchard, overwintering egg, parasitism
