[Oviposition and development of Halyomorpha halys (Stål) and Homalogonia obtusa (Walker) (Heteroptera: Pentatomidae) on apple trees]
Japanese Journal of Applied Entomology and Zoology 46 (1), 1-6
Abstract: The oviposition site and development of Halyomorpha halys and Homalogonia obtuse were examined in apple orchards from 1997 to 2000. Many egg batches of both species were found on the apple leaves. When adults of both species were released on the apple trees in late May, progeny adults emerged the middle of August. Larvae fed on the current shoots, leaves and fruit. Half of the overwintering female adults of Ha. halys that immigrated to the apple orchards had mature eggs. Ha. halys adults right after overwintering that were released on the apple tree in early May began to oviposit on the apple leaves starting in early June. These observations suggest that apple trees can be one of the early host plants for both Ha. halys and Ho. obtusa.
