Özet

The brown marmorated stink bug, Halyomorpha halys,is an invasive agricultural pest of fruit trees and vegetables. Egg parasitoids play a key role in the reducing ofH. halyspopulations.Ooencyrtus kuvanae(Howard) (Hymenoptera: Encyrtidae) can parasitizeH. halysand complete its life cycle in this host species. Many factors can influence this parasitoid-host relationship. Of these factors, we evaluated the effect of female age, exposure time, and host species on the biological characteristics and fecundity ofO. kuvanaereared on eggs ofH. halysas well as another previously known hostPhilosamia ricini(Lepidoptera: Saturniidae). In this study, we used a 3-year-old laboratory colony ofO. kuvanae. Parasitism rates positively affected by exposure time inP. ricini. The highest parasitism rates were obtained in 5- and 7-day-old females of both hosts. The highest emergence rates were recorded onP. ricinifor 5- and 7-day-old femaleP. ricini(81.8% and 84.8%, respectively). The development time ofO. kuvanaeranged from 18.4 to 19.1 days onH. halysand 17.7 to 18.3 days onP. ricini. The longevity ofO. kuvanaethat were provided honey was 38.5 and 47.8 days onH. halysandP. ricini, respectively. The longevity ofO. kuvanaethat were not provided honey was 2.3 and 2.8 days onH. halysandP. ricini, respectively. The sex ratio was male-biased (36.5% female) onH. halysand female-biased (55.2% female) onP. ricini. Fecundity ofO. kuvanaewas 37.7 and 59.6 progeny per female forH. halysandP. ricini,respectively. The performance ofO. kuvanaewas lower when compared with its performance on the hostP. ricini. Our results suggest thatO. kuvanaehas potential as new biological control agent forH. halys.
