Abstract


ADVANCES IN EMERGENT INSECT SAMPLING: NEW STICKY TRAP DESIGNS AND AUTOMATED SAMPLE PROCESSING

With growing interest in the collection of emergent adult aquatic insects for ecological studies, there comes a need for improved methods, trap designs, and processing techniques for sampling and analyzing these groups. In this presentation, we will describe a novel Petri dish-based sticky trap design and four-dimensional pole mount, which allows for rapid, low-cost trap deployment in remote locations and also enables the estimation of insect flight direction. Further, we will discuss an image analysis protocol for sample processing of these Petri traps, whereby traps are photographed and then analyzed using common software programs. This automated approach has resulted in an 80% decrease in human processing time (down to ~ 1 minute per sample), which counts and identifies taxa to the family level with >90% accuracy. To demonstrate the efficacy of these methods, we will present a case study application from a recent field campaign on the Colorado River in Grand Canyon, Arizona, USA.
