摘要

手蛾科(双翅目)是少数在温带冬季出现的具有代表性的昆虫;过去的研究表明，冬季出现的物种寿命较长。我们扩展了先前的研究，研究了不同气温对寿命和产卵率的影响，以及产卵状态是否影响寿命。2020年冬季，在卡姆登州立公园(美国明尼苏达州)的一条泉水溪流附近收集了成年摇尾虫(n = 339)。将昆虫分为2°C、6°C和环境室外(AO)温度处理组，测定其寿命和产卵率的差异。每天监测行为直到死亡。2℃组的寿命明显长于6℃组和AO组，平均寿命分别为19.8、14.9和13.9天。此外，与2°C和AO组相比，6°C组的雌性似乎有更高的产卵率。结果表明，低温可能会延迟或抑制产卵，这表明产卵率对长寿的潜在权衡。

Longevity and oviposition of winter-emerging Chironomidae (Insecta: Diptera) at varying low temperatures

Abstract Chironomidae (Diptera) are among the few insects with representatives that emerge during temperate winters; past work shows winter-emerging species are long-lived. We extend previous studies, examining the influence that varying air temperatures have on longevity and oviposition rates, and whether oviposition status impacts longevity. Adult chironomids (n = 339) were collected during winter of 2020 near a spring-fed stream in Camden State Park (Minnesota, USA). Insects were separated into 2 °C, 6 °C, and ambient outdoor (AO) temperature treatment groups to determine differential longevity and oviposition rates. Behaviours were monitored daily until death. The 2 °C group lived significantly longer than both 6 °C and AO groups, with mean longevities of 19.8, 14.9, and 13.9 days, respectively. Additionally, females held at 6 °C appear to have higher oviposition rates compared to 2 °C and AO groups. Results suggest low temperatures may delay or inhibit oviposition, suggesting a potential tradeoff of oviposition rate in favour of longevity.

期刊介绍： Aquatic Insects is an international journal publishing original research on the systematics, biology, and ecology of aquatic and semi-aquatic insects. The subject of the research is aquatic and semi-aquatic insects, comprising taxa of four primary orders, the Ephemeroptera, Odonata, Plecoptera, and Trichoptera but also aquatic and semi-aquatic families of Hemiptera, Coleoptera, and Diptera, as well as specific representatives of Hymenoptera , Lepidoptera, Mecoptera, Megaloptera , and Neuroptera that occur in lotic and lentic habitats during part of their life cycle. Studies on other aquatic Hexapoda (i.e., Collembola) will be only accepted if space permits. Papers on other aquatic Arthropoda (e.g., Crustacea) will not be considered, except for those closely related to aquatic and semi-aquatic insects (e.g., water mites as insect parasites). The topic of the research may include a wide range of biological fields. Taxonomic revisions and descriptions of individual species will be accepted especially if additional information is included on habitat preferences, species co-existing, behavior, phenology, collecting methods, etc., that are of general interest to an international readership. Descriptions based on single specimens are discouraged. Detailed studies on morphology, physiology, behavior, and phenology of aquatic insects in all stadia of their life cycle are welcome as well as the papers with molecular and phylogenetic analyses, especially if they discuss evolutionary processes of the biological, ecological, and faunistic formation of the group.
