Abstract: Endoparasitoid Peristenus spretus Chen et van Achterberg is one of the important nymph parasitoid of green mirid bug, Apolygus lucorum (Meyer-Dür). Field experiments on releasing P. spretus for control of A. lucorum in jujube orchards were conducted from 2013 to 2014 in Zhanhua county, Shandong province. The results showed that three releases of female P. spretus at rates of 1:50, 1:100 and 1:200 (parasitoid vs. green mirid bug) in cages, the average parasitic rates were 77.8%, 63.8% and 39.5%, respectively, which is higher on the average than than that from single release. In open jujube orchard trial, the average parasitic rate in 3 months was 32.2% in released plots, 9.5 times of the parasitism in control (non release) orchard. These results indicate that mass releasing P. spretus can provide substantial control of A. lucorum in jujube orchard.

Key words: Apolygus lucorum, Peristenus spretus, parasitic rate, filed release, control effect
