Host preference is an important behaviour in parasitoid females as they must choose suitable hosts for their offspring. Preference includes location, recognition and acceptance of hosts. Both genetic environmental factors can affect all those stages. Here, we focus on two (rearing history experience) affecting host the wasp genus Nasonia (Hymenoptera: Chalcidoidea: Pteromalidae: Pteromalinae), ...

A new species of the genus Mesopolobus Westwood, 1833, robiniae Lakatos & László sp. nov., is described and illustrated from east-central Europe (Romania Hungary). The was reared black locust (Robinia pseudoacacia) seedpod samples, where it most likely parasitizes locust’s seed predator Bruchophagus Zerova, 1970. Here we present report on its ecological relationships within European com...

Wasps of the genus Nasonia are important biological control agents of house ßies and related Þlth ßies, which are major vectors of human pathogens. Species of Nasonia (Hymenoptera: Pteromalidae) are not easily differentiated from one another by morphological characters, and molecular markers for their reliable identiÞcation have been missing so far. Here, we report eight single-nucleotide polym...

Wasps of the genus Nasonia are important biological control agents of house flies and related filth flies, which are major vectors of human pathogens. Species of Nasonia (Hymenoptera: Pteromalidae) are not easily differentiated from one another by morphological characters, and molecular markers for their reliable identification have been missing so far. Here, we report eight single-nucleotide p...

A review of the genera and species of Hymenoptera Parasitica and Chrysidoidea reported so far from Reunion Island is provided with host information. Data presented here is based on a review of the existing literature by the authors. The list includes: (1) 156 species of Ichneumonoidea belonging to 65 genera and 25 subfamilies (Braconidae: Agathidinae, Alysiinae, Aphidiinae, Braconinae, Charmont...

The Oriental species of Apsilocera Bouček, 1956 (Hymenoptera: Pteromalidae) are revised and the limits of the genus are reevaluated. Bulolosa Bouček, 1990 and Kratinka Bouček, 1988 are treated as synonyms of Apsilocera, syn. n. Bulolosa bidens Bouček and Kratinka brevis Bouček are transferred to Apsilocera as A. bidens (Bouček) and A. brevis (Bouček) comb. n., respectively. Twelve new species (...

Wesenbergia Hartman, 1955 (Annelida, Hesionidae) is both preoccupied and a junior homonym of Wesenbergia Kryger, 1943 (Hymenoptera, Pteromalidae), and must be renamed. Elisesionenom. n. is proposed as a replacement name, derived from the combination of the first name of the discoverer, Elise Wesenberg-Lund, and Hesione Savigny in Lamarck, 1818. Elisesione mezianeisp. n., is described from the W...
