Abstract

Abstract This article investigates inter-individual repeatability in distance moved in an open-field test for larval Limnephilus lunatus Curtis, 1834. Repeatability across four trials (two-day trial intervals) was comparable to previous studies on arthropod species (repeatability: R = 0.37), indicating that L. lunatus is a suitable model species in this research field. Two potential nuisance factors were corrected for: (1) progressively declining activity over consecutive trials and (2) case mass:body mass ratio, affecting activity negatively. These factors require consideration in behavioural experiments on larval caddisflies. Pairwise correlations of distance moved among trial days showed that behaviour in the first trial did not correspond well with behaviour in the following trials. Re-analysing the data using only trials 2 to 4 increased the repeatability (repeatability: R = 0.50), suggesting that future studies should consider not including data derived from initial trials, as the initial trial may constitute a different context than the following ones.

露天试验中月牙Limnephilus lunatus Curtis, 1834(毛翅目)幼虫行为的重复性

摘要本文研究了在露地试验中对月尾鲎幼虫移动距离的个体间重复性。Curtis，1834。四项试验（两天试验间隔）的重复性与之前对节肢动物物种的研究相当（重复性：R = 0.37），表明新月乳杆菌是该研究领域的适宜模式种。校正了两个潜在的滋扰因素：（1）在连续试验中活动性逐渐下降；（2）病例质量与身体质量比，对活动性产生负面影响。这些因素需要在球童幼虫的行为实验中加以考虑。试验天数之间距离移动的成对相关性表明，第一次试验中的行为与随后试验中的表现不太一致。仅使用试验2至4重新分析数据增加了重复性（重复性：R = 0.50），这表明未来的研究应考虑不包括来自初始试验的数据，因为初始试验可能与以下试验构成不同的背景。

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.
