Abstract

ABSTRACTDiapause is a process of decreased metabolic activity in insects. In latitudes with a well-defined cold season, diapause or hibernation is a strategy to survive in periods of resource scarcity. In Pentatomidae, this phenomenon is studied mainly in non-natural environments and with species of economic importance. This work aimed to determine which variables influence the abundance of Brachystethus geniculatus on its hibernation site, Bromelia antiacantha. Samplings were carried out monthly, from July to September of 2019, in a remnant of Atlantic Forest in southern Brazil. The height, diameter, cup height, leaf width, and abundance of bromeliads per plant cluster were evaluated for their correlation with the abundance of B. geniculatus in bromeliads. We collected 24 individuals for analysis of fat bodies, in order to check diapause. We found 70 individuals of B. geniculatus distributed in 33 of the 61 bromeliads examined. The number of B. geniculatus per bromeliad was positively correlated with the cup height, that influences the opening of the leaves and consequently decreases the exposure to environmental weathering, and the number of bromeliads per group, possibly because more leaves and spines around the cup may help avoid predation. Parasitism on B. geniculatus by tachinid flies was recorded in the field.KEYWORDS: Atlantic Forestcorrelationstink bugmicro-habitatparasitism AcknowledgmentsWe thank all the friends and colleagues who help in the field search and the manuscript revision, especially Dr. Filipe Michels Bianchi (UFRGS), Dr. Luiza Rodrigues Redaelli (UFRGS) and Dr. Patrick Colombo (SEMA), for their valuable contributions to the final version of the manuscript.Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingThis study was partially financed by CNPq fellowship to the first author [grant 122920/2016-3].

哪些植物性状重要?凤梨。(凤梨科)作为Brachystethus geniculatus (Fabricius)(半翅目，蝽科，凤梨科)的冬眠地

摘要滞育是昆虫代谢活性降低的过程。在寒冷季节分明的纬度地区，滞育或冬眠是在资源匮乏时期生存的一种策略。在Pentatomidae中，这种现象主要在非自然环境和具有经济重要性的物种中进行研究。这项工作旨在确定哪些变量影响Brachystethus geniculatus在其冬眠地点凤梨(Bromelia antiacantha)的丰度。2019年7月至9月，在巴西南部大西洋森林的遗迹中每月进行一次采样。分析了凤梨科植物的株高、株径、株杯高、叶宽、颖花丰度与凤梨科植物中小叶蛾丰度的相关性。我们收集了24个个体进行脂肪体分析，以检查滞育。在61个凤梨科植物中，33个凤梨科植物中发现了70个假凤梨科植物个体。每个凤梨的数量与杯高呈正相关，影响叶片的开口，从而减少环境风化的暴露;每组凤梨的数量可能是因为杯周围更多的叶子和刺有助于避免捕食。在田间记录了速蝇对小黄蜂的寄生情况。感谢所有在野外检索和稿件修改过程中给予帮助的朋友和同事，特别是Filipe Michels Bianchi博士(UFRGS)、Luiza Rodrigues Redaelli博士(UFRGS)和Patrick Colombo博士(SEMA)对稿件定稿的宝贵贡献。披露声明作者未报告潜在的利益冲突。本研究部分由CNPq奖学金资助给第一作者[grant 122920/2016-3]。

期刊介绍： There is still a far from complete understanding of the complex ecosystems in the Neotropics, although they have been studied since the first expeditions of the old world naturalists Marcgrave, Humboldt, Spix, Darwin, Bates and Müller. The aims and scope of the Journal are, besides taxonomic and zoogeographic surveys, analyses of animal communities and their relationship with biotic and abiotic environmental conditions. This includes the fauna of both terrestrial and fresh water ecosystems in the Neotropics. Contributions that represent original research and mini-reviews are welcome. Manuscripts presenting just checklists and new geographic records are not considered for publication. If manuscripts do not meet the requirements of the journal, the editors reserve the right to reject manuscripts on submission or to ask for revisions prior to formal peer review.
