The area is also recognised for hosting a group of understudied minute leaf-litter dwellers stygnids, represented by the following monotypic genera: Gaibulus Roewer, 1943; Iguarassua Roewer, 1943; and Kaapora Pinto-da-Rocha, 1997. In this study, we describe a male specimen of Iguarassua schubarti Roewer, 1943; describe two new Iguarassua species, Iguarassua brejoensis sp. nov. and Iguarassua villarreali sp. nov.; examine the type series of Kaapora minutissimus (Roewer, 1943); and discuss the overall relationships of the leaf-litter Stygnidae in the Northern Atlantic Forest. We propose K. minutissimus syn. nov. to be a junior synonym of I. schubarti, thereby synonymising Kaapora syn. nov. under Iguarassua, and identify key diagnostic characters related to pedipalp setae curvature and penis morphology, indicating that all current Atlantic Forest leaf-litter stygnids, including Gaibulus, are possibly monophyletic, likely placed in Stygninae and are most closely related to Pickeliana Mello-Leitão, 1932.","PeriodicalId":8574,"journal":{"name":"Austral Entomology","volume":"64 4","pages":""},"PeriodicalIF":1.1,"publicationDate":"2025-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/aen.70024","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145272094","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their favourable toxicological and environmental profiles have led to broad registration across multiple pest species and crop types. However, widespread use is known to compromise insecticidal efficacy due to resistance, and concerns have been raised about the sustainability of these insecticides in Australian agriculture, particularly since the incursion of Spodoptera frugiperda in 2020. As a first step in pre-emptive management of S. frugiperda, baseline susceptibility to cyantraniliprole was determined in larval bioassays performed on 16 field populations collected from maize and sweet corn between 2020 and 2021 during the initial period of establishment in Australia. There was a narrow (2.1-fold) range of intra-specific variation in cyantraniliprole susceptibility amongst field populations. The average median lethal concentration was 0.088 mg L−1, which was significantly higher than in Helicoverpa armigera (LC50 = 0.037 mg L−1). An analysis of relative diamide toxicity showed that while the median concentration of chlorantraniliprole was significantly higher than cyantraniliprole in S. frugiperda, there was no significant difference between the toxicity of chlorantraniliprole and cyantraniliprole at the LC99.9 level. Using the dose–response data generated from these bioassays and taking into account empirical survival, a concentration of 2 mg L−1 of cyantraniliprole was determined to be a suitable dose for discriminating between cyantraniliprole-susceptible and cyantraniliprole-insensitive phenotypes of S. frugiperda.","PeriodicalId":8574,"journal":{"name":"Austral Entomology","volume":"64 4","pages":""},"PeriodicalIF":1.1,"publicationDate":"2025-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145224375","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}

Here, we use allozyme electrophoresis and DNA sequencing of mitochondrial and nuclear genes to test the hypothesis that A. strombylosa, as currently treated, is a single biological species. We find that the ‘eastern’ and ‘western’ forms of A. strombylosa sens. lat. are distinct species with no evidence of recent gene flow despite both forms sometimes being in close geographic proximity. The two species are morphologically distinct and induce galls on different Sections of Eucalyptus L'Herit.

No additional information is known about these genera apart from their original descriptions. These two poorly known genera are herein treated as junior synonyms of Campylocheta based on the study of the holotypes of the type species and additional specimens from Ecuador.

This study investigated the necrophagous insect communities associated with carrion of silver gulls (Chroicocephalus novaehollandiae) on a small nearshore island off the east coast of Australia, to assess how necrophagous insect communities on islands compare with the mainland community, and the degree to which these communities varied over time. Over three breeding seasons, we analysed what insect species were colonising gull carcasses and, using baited traps, compared total adult community composition and richness of carrion-associated insect species on the island with the adjacent mainland. Our findings reveal that an island separated by less than 500 m from the mainland can harbour distinct carrion-breeding fly assemblages. These assemblages vary between years but are notably dominated by a potential seabird-carrion specialist fly—the littoral species Calliphora maritima. These results underscore the importance of seabird carrion as a critical resource for necrophagous insects on islands and contribute to our understanding of how island environments influence insect community dynamics and specialisation.","PeriodicalId":8574,"journal":{"name":"Austral Entomology","volume":"64 3","pages":""},"PeriodicalIF":1.1,"publicationDate":"2025-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/aen.70023","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144843613","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While parasitoids are the better-studied natural enemies of this leafhopper, its predators remain largely unknown. This study records, for the first time, 26 predator species [14 spiders, three lacewings (Chrysopidae), two assassin bugs (Reduviidae), one big-eyed bug (Geocoridae), one hoverfly (Syrphidae), four ladybugs (Coccinellidae) and two pincer wasps (Dryinidae)] as active predators of the vector in cornfields of northern Argentina. These records, along with the three previously known species, form a complex of 29 species preying on different stages of the vector in Argentina. With this contribution, 40 species of predators are now documented across the Americas, providing a valuable natural resource that should be conserved.","PeriodicalId":8574,"journal":{"name":"Austral Entomology","volume":"64 3","pages":""},"PeriodicalIF":1.1,"publicationDate":"2025-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144843618","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}
