Parasitoides calcidoides (Hymenoptera: Chalcidoidea) asociados con Sibinia subelliptica (Desbrochers, 1873) (Coleoptera: Curculionidae) en Bulgaria

The weevil Sibinia subelliptica (Desbrochers, 1873) and a rich complex of associated chalcidoid parasitoids were reared from inflorescences of Dianthus giganteus d’Urv. (Caryophyllaceae) in Bulgaria. The following taxa were identified: Aprostocetus venustus (Gahan) and Baryscapus sp. near garganus (Domenichini, 1958) (Eulophidae); Eupelmus barai Fusu and E. microzonus Förster (Eupelmidae); Aximopsis augasmae (Zerova), A. collina (Zerova), Eurytoma coleophorae Zerova and E. coleopterae Zerova (Eurytomidae); Catolaccus crassiceps (Masi) and Pteromalus ochrocerus (Thomson) (Pteromalidae); and Exopristus trigonomerus (Masi) (Torymidae). Two of these, E. coleophorae and E. coleopterae, are new records for Bulgaria. All parasitoid-host relationships are documented here for the first time. New plant associations with D. giganteus are recorded here for all reared parasitoids except E. barai and E. microzonus. The new trophic association of S. subelliptica with D. giganteus is established here.El gorgojo Sibinia subelliptica (Desbrochers, 1873) y un rico complejo de parasitoides calcidoides asociados se criaron a partir de inflorescencias de Dianthus giganteus d’Urv. (Caryophyllaceae) en Bulgaria. Se identificaron los siguientes taxones: Aprostocetus venustus (Gahan) y Baryscapus sp. cercana a garganus (Domenichini, 1958) (Eulophidae); Eupelmus barai Fusu y E. microzonus Förster (Eupelmidae); Aximopsis augasmae (Zerova), A. collina (Zerova), Eurytoma coleophorae Zerova y E. coleopterae Zerova (Eurytomidae); Catolaccus crassiceps (Masi) y Pteromalus ochrocerus (Thomson) (Pteromalidae); y Exopristus trigonomerus (Masi) (Torymidae). Dos de éstos, E. coleophorae y E. coleopterae, son registrados como nuevos para Bulgaria. Todas las mencionadas relaciones parasitoide-hospedador se documentan por primera vez, así como se registra por primera vez la asociación de la planta D. giganteus con todos los parasitoides obtenidos, excepto en los casos de E. barai y E. microzonus. Se establece la nueva asociación trófica de S. subelliptica con D. giganteus

Alien seed beetles (Coleoptera: Chrysomelidae: Bruchinae) in Europe

Under the framework of the DAISIE consortium, whose main mission is to make an inventory of the alien invasive species of Europe and its islands, we review the current state of knowledge and provide an up-to-date catalogue and distributional status for alien seed beetles (Coleoptera: Chrysomelidae: Bruchinae) in Europe. This work is based on studies of the species detected from the last century to the present, but with greater emphasis on the beginning of the 21st century, during which new biological studies have been carried out and findings made in European countries. The main objective of this paper is to focus on this last fact, which has promoted new views on the existing and potential threat of exotic bruchids in relation to climate change. This must now be regarded as a matter of concern for European agricultural and environmental policies. Only species of exotic origin introduced in European regions outside their native range were considered. Therefore, species of European origin spreading to new countries within Europe are not treated. Also, we provide a new approach to classifying alien seed beetle species according to their ability to become established, distinguishing between the well-established and those that may appear in seed stores but are not capable of invading natural and agricultural ecosystems. We present a taxonomic characterization of the alien bruchids found in Europe, providing an illustrated key based on external morphological characters of adults. The key facilitates the identification of the sixteen most frequently recorded genera, which represent 37 of the 42 species of exotic species recorded in Europe up to the present, whether established, not established or occasional. Finally, we provide a summary of the state of knowledge of the taxonomy and biology of the 20 most worrying species as pests, both established and non-established. This includes, where appropriate, an illustrated key for the identification of species. The study reveals that the majority of exotic bruchid species in Europe originate in Asia and Africa, from host plant species imported for ornamental or forestry purposes, and that a greater effort in European customs control is advisable
