The present study is an attept to apply the null models to explain the structure of aquatic insects a small saline water source located at south of Antofagasta town (23°47’ S, Chile), using species associations and niches sharing null models. The results reveal a low taxa number, specifically of Diptera (Ephydridae, Ceratopogonidae and Nematocera). The null models of species associations reveal that the associations are random. Evaluation of the niche sharing reveal that species share ecological niches, and as a consequence there are interspecific competition. The reported taxa are similar with communities for inland water saline ecosystems as far as community structure and taxonomic groups are concerned.","PeriodicalId":13463,"journal":{"name":"Indian journal of entomology","volume":"712 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140469478","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Soxhlet extraction by all the solvents showed a distinct effect on larval mortality, adult emergence, and the growth and development of second-instar larvae than cold maceration extraction. Soxhlet ethanolic extract at 5% had significantly better insecticidal activity than cold maceration, with complete larval mortality. The antifeedant index was also higher in ethanol extract, followed by ethyl acetate and hexane extract. However, there was no significant variation in the developmental period.
