Sampling small-sized, nocturnal amphibiotic insects poses practical questions onto which technique should be used. This is the case of Trichoptera adults, which have been sampled mostly by using pan, light sheets associated with UV lamps. The urgency of selective and efficient sampling, however, requires quantitative comparison of different methods. We evaluated in situ efficiency of two techniques for sampling Trichoptera adults – light pan traps and light sheet attraction, both attached to UV and white lights – in a protected area in a rainforest fragment. The rarefaction curves indicate that sampling was efficiently robust to represent the local assemblage for both techniques. No significant differences were observed in caddisfly diversity according to the method. Overall, sex ratio of the adults did not differ, as both males and females were caught in similar proportions. We conclude that both techniques can be used for short-term inventories of caddisfly diversity, especially in areas where collection licences limit the number and range of sampled insects. Advantages and disadvantages of each technique, regarding representativeness, effort, selectiveness, and efficiency are discusses in this study.

对小型夜间两栖昆虫进行采样提出了实用的问题，应该使用哪种技术。鳞翅目成虫就是这种情况，它们大多是通过使用与紫外线灯相关的平底灯来取样的。然而，选择性和有效采样的紧迫性要求对不同方法进行定量比较。我们就地评估在热带雨林碎片中受保护的区域中，对鳞翅目成虫进行采样的两种技术的效率–分别与紫外线和白光相连的光盘陷阱和光片引力。稀疏度曲线表明，对于两种技术，采样都非常有效地代表了本地组合。根据该方法，在dis虫多样性中未观察到显着差异。总体而言，成年人的性别比例没有差异，因为男性和女性的捕获比例相似。我们得出的结论是，这两种技术都可用于虫蝇多样性的短期清单，尤其是在采集许可证限制了采样昆虫的数量和范围的地区。在这项研究中讨论了每种技术的优缺点，涉及代表性，工作量，选择性和效率。
