Ecological and morphological characteristics of the endoparasitoids of larval Acronicta rumicis (Lepidoptera: Noctuidae)

The Hymenopterans Glyptapanteles liparidis, Microplitis sp. and Diadegma sp. were found to be larval parasitoids and koinobionts of Acronicta rumicis (Lepidoptera: Noctuidae). Mesochorus semirufus is believed to be a new unreported hyperparasitoid of G. liparidis, which, along with M. semirufus, is a gregarious parasitoid. In contrast, the parasitoids Microplitis sp. and Diadegma sp. are solitary. All of the hymenopteran parasitoids are multivoltine insects that emerge from A. rumicis more than once.
