Bionomics, Venomics and Diagnostics
V01 Bionomics of bee and wasp species known as releasers of venom allergies in Central Europe with special emphasis on the genus Polistes V. Mauss Zentrum für Wespenkunde, Michelfeld, Deutschland About 30 species of eusocial Apinae and 12 species of eusocial Polistinae and Vespinae are possible releasers of venom allergies in Germany. Twenty-three of these species occur regularly or occasionally in residential or recreational areas. Sting risk is influenced by geographical distribution, phenology, nest sites, and foraging behaviour of these species. The defensive behaviour of social wasps and bees varies depending on colony size and phylogenetic position. Most important elicitors of venom allergies are the honey-bee (Apis mellifera) and two species of vespine wasps, namely Vespula vulgaris and Vespula germanica. Polistine wasps of the genus Polistes build small nests consisting of a single open comb without a nest envelope heated by radiation of the sun. The most common species is Polistes dominula. Hitherto the nests of this synanthropic species were regularly erected within buildings at hot, sun exposed sites mainly under roofs with bare shingles without insulation. A survey among members of a conference of more than forty volunteer wasp conservation advisers in Baden-Württemberg revealed that in warm regions of this state the abundance of Polistes species has distinctly increased especially in housing areas, which is probably due to climate change. Moreover, Polistes dominula nests are now more often build in open situations, typically at unexpected sites, like e. g. casings of exterior lights, hollow banisters, letterboxes or even the bodywork of cars. As a consequence, accidental nest disturbance by humans provoking defensive attacks by these wasps have probably become more frequent, leading to a higher probability of sting reactions against Polistes venom in south Germany.
