Comparisons of parasitism and developmental properties of Trissolcus japonicus (Hymenoptera: Scelionidae) reared on eggs of three species of fruit-piercing stink bugs
Applied Entomology and Zoology 56 (3), 379-383
Abstract: An egg parasitoid, Trissolcus japonicus (Ashmead) (Hymenoptera: Scelionidae), was reared on eggs of Plautia stali scott (Hemiptera: Pentatomidae), Halyomorpha halys (Stål) (Hemiptera: Pentatomidae), and Glaucias subpunctatus (Walker) (Hemiptera: Pentatomidae), and parasitism rates and developmental properties were compared to clarify their suitability as hosts. The parasitoids successfully emerged from more than 90% of P. stali or G. subpunctatus eggs, whereas a lower rate of T. japonicus emerged from the eggs of H. halys. The developmental period of T. japonicus in the eggs of H. halys was longer than in the other two species, and the body size of T. japonicus that emerged from the eggs of H. halys was also larger than from the other two species. From these results, factors related to parasitism and developmental properties were discussed.
