Abstract

Dinidorid stinkbugs were reported to possess a conspicuous tympanal organ on female hindlegs. In this study, we show that this organ is specialized to retain microbial symbionts rather than to perceive sound. The organ’s surface is not membranous but consists of porous cuticle in which each pore connects to glandular secretory cells. In reproductive females, the hindleg organ is covered with fungal hyphae that grow from the pores. Upon oviposition, the females transfer the fungi from the organ to the eggs, where the hyphae physically protect the eggs against wasp parasitism. The fungi comprise a diversity of mostly low-pathogenicity Cordycipitaceae.

昆虫后腿上的防御性真菌共生

据报道，在雌性的后腿上有一个明显的鼓室器官。在这项研究中，我们表明这个器官是专门用来保留微生物共生体而不是感知声音的。器官的表面不是膜状的，而是由多孔角质层组成，每个孔与腺分泌细胞相连。在生殖雌性中，后腿器官覆盖着从毛孔生长的真菌菌丝。产卵后，雌性将真菌从器官转移到卵上，在那里菌丝物理上保护卵免受黄蜂寄生。真菌包括多种低致病性虫草科。

期刊介绍： Science is a leading outlet for scientific news, commentary, and cutting-edge research. Through its print and online incarnations, Science reaches an estimated worldwide readership of more than one million. Science’s authorship is global too, and its articles consistently rank among the world's most cited research. Science serves as a forum for discussion of important issues related to the advancement of science by publishing material on which a consensus has been reached as well as including the presentation of minority or conflicting points of view. Accordingly, all articles published in Science—including editorials, news and comment, and book reviews—are signed and reflect the individual views of the authors and not official points of view adopted by AAAS or the institutions with which the authors are affiliated. Science seeks to publish those papers that are most influential in their fields or across fields and that will significantly advance scientific understanding. Selected papers should present novel and broadly important data, syntheses, or concepts. They should merit recognition by the wider scientific community and general public provided by publication in Science, beyond that provided by specialty journals. Science welcomes submissions from all fields of science and from any source. The editors are committed to the prompt evaluation and publication of submitted papers while upholding high standards that support reproducibility of published research. Science is published weekly; selected papers are published online ahead of print.
