Patterns of vertical oviposition stratification were examined in this study by placing basal and canopy level oviposition traps in relatively steep and flat terrains, as well as in flood-prone riverbank vs upland settings. Strong stratification existed in both steep and flat terrains, with <i>Ae. triseriatus</i> favoring basal ovitraps and <i>Ae. hendersoni</i> favoring canopy ovitraps. Contrary to expectations, <i>Ae. hendersoni</i> displayed even more marked preference for canopy ovitraps in steeper terrain. Both species avoided basal ovitraps in flood-prone locations, where <i>Ae. triseriatus</i> oviposited only in canopy ovitraps and greatly outnumbered <i>Ae. hendersoni</i> in canopy ovitraps. In contrast, the expected stratification was found in nearby upland habitats.</p>","PeriodicalId":56065,"journal":{"name":"Journal of Vector Ecology","volume":"48 2","pages":"113-123"},"PeriodicalIF":1.7,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41241277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
