Hymenoptera Complex Associated with and spp. in Peach Orchards in Northeastern Spain and Prospects for Biological Control of Aphids.

Aphids are a serious pest for peach crops. They have traditionally been managed with insecticides, but there is increasing concern about the risk that insecticides pose to both humans and the environment. As a first step to use biological control in aphid management, we conducted a 3-year field survey in northeastern Spain to determine which parasitoids and hyperparasitoids were most prevalent on two aphids, (Sulzer) and spp.

Gatesina colombiana n. gen. n. sp. (Hymenoptera: Chalcidoidea, Eurytomidae), new Rileyinae associated with Myrcianthes (Myrtaceae) from Colombia.

The Neotropical fauna of Chalcidoidea (Hymenoptera) is poorly known, with numerous undescribed species and even genera. Here, we describe a new genus that also includes a new species that parasitizes Eurytominae gall-formers in fruits of Myrcianthes (Myrtaceae) in Colombia. Its conspicuous morphology supports the description of a new eurytomid genus and species, Gatesina colombiana n.
