@article{oai:nagasaki-u.repo.nii.ac.jp:00027338, author = {Noguchi, Daisuke and Ikeda, Kenichi}, issue = {3}, journal = {Serket}, month = {May}, note = {Not only spiders (Arachnida: Araneae) but also vespine wasps (Hymenoptera: Vespidae: Vespinae ) including hornets (the genus Vespa ) and yellowjackets (the genera Vespula and Dolichovespula ) belong to top predator community within arthropod food webs . Thus, between two communities, intraguild predation (IGP) defined as killing and eating among potential competitors is considered to occur. However, the possibility has not investigated enough so far. In the present study by means of bibliographic survey it has been reported that the observations of predation on Vespa , Vespula , and Dolichovespula of vespine wasps by spiders; i.e., large web building spider Argiope spp. (Araneidae) captured Vespa orientalis , A. amoena and A. bruennichi fed on hornets V. analis , jumping spiders such as Phidippus aud ax (Salticidae) preyed on yellowjackets Vespula germanica , Dolichovespula maculate , and D. arenaria ), a tunnel web spider Porrhothele antipodiana ( consumed Vl. germanica , orb weavers A. aurantia and A. florida captured Vl. squamosa diet of wandering spider Phoneutria boliviensis Ctenidae) contained Vespula sp. By contrast, 20 cases were that vespine wasps foraged spiders from 10 publications with certain species names. Accordingly, symmetric IGP between vespine wasps and spiders is suggested. Observations on kleptoparasitism by hornets, an escaping from a spider’s web by a vespulid wasp, and a killing between a spider and a yellowjacket each other were also known. Although spiders are both prey and predators of vespine wasps, further studies are required to elucidate quantitatively the interaction of prey predator relationship as symmetric IGP., Serket, 18(3), pp.287-298; 2022}, pages = {287--298}, title = {Intraguild predation on hornets and yellowjackets of vespine wasps by spiders, and vice versa.}, volume = {18}, year = {2022} }
