Indirect interactions between a native and a supposedly non-native wasp species (Hymenoptera: Vespidae: Eumeninae: Anterhynchium)
Non-native species pose a threat to native organisms. When non-native and native species are closely related, the former can often competitively exclude the latter. Many studies have focused on competitive exclusion of native insect species by non-native eusocial hymenopterans, including ants, hornets, paper wasps and bees. Although solitary species of wasps have been introduced in many regions, few studies have investigated the effects of these insects on their native congeners. We investigated competitive interactions between native and non-native solitary wasps belonging to the same genus (Hymenoptera: Vespidae: Eumeninae: Anterhynchium). Specifi cally, we compared resource use and natural enemies of the native Anterhynchium fl avomarginatum and supposedly non-native A. gibbifrons at a forest edge in Takasago, Hyogo, Japan, in June–October 2019, using trap nests (bamboo canes). Of 950 bamboo canes, 70 (7.4%) and 50 (5.3%) were used as nests by A. fl avomarginatum and A. gibbifrons, respectively. Anterhynchium fl avomarginatum produced two generations over the period studied, whereas A. gibbifrons produced only one. Although A. gibbifrons began nesting two weeks after A. fl avomarginatum, the nesting period of A. gibbifrons overlapped that of the fi rst nesting period of A. fl avomarginatum. Nest architecture and the inner diameter of the canes used by both species were similar, suggesting potential competition for nesting resources. Anterhynchium fl avomarginatum used larvae of 14 species of moths (Lepidoptera: Crambidae, Pyralidae, Tortricidae) as food for their larval offspring, whereas A. gibbifrons used only a single species, Demobotys pervulgalis (Lepidoptera: Crambidae). Prey species were exclusive to each wasp species, indicating no competition for this resource. Three parasitoid species, Macrosiagon nasutum (Coleoptera: Ripiphoridae), Amobia distorta (Diptera: Sarcophagidae) and Megaselia sp. (Diptera: Phoridae), attacked both Anterhynchium species. The percentage parasitism by Amobia distorta was higher for the native A. fl avomarginatum. Anterhynchium gibbifrons may indirectly affect A. fl avomarginatum via shared parasitoids.
期刊介绍:
EJE publishes original articles, reviews and points of view on all aspects of entomology. There are no restrictions on geographic region or taxon (Myriapoda, Chelicerata and terrestrial Crustacea included). Comprehensive studies and comparative/experimental approaches are preferred and the following types of manuscripts will usually be declined:
- Descriptive alpha-taxonomic studies unless the paper is markedly comprehensive/revisional taxonomically or regionally, and/or significantly improves our knowledge of comparative morphology, relationships or biogeography of the higher taxon concerned;
- Other purely or predominantly descriptive or enumerative papers [such as (ultra)structural and functional details, life tables, host records, distributional records and faunistic surveys, compiled checklists, etc.] unless they are exceptionally comprehensive or concern data or taxa of particular entomological (e.g., phylogenetic) interest;
- Papers evaluating the effect of chemicals (including pesticides, plant extracts, attractants or repellents, etc.), irradiation, pathogens, or dealing with other data of predominantly agro-economic impact without general entomological relevance.
