The synonymy between Pachypasa otus (Drury, 1777) and P. otus fulvescens Kotzsch, 1932 is supported by the lack of any stable morphologic characters and average distance of 0.3% in the cytochrome C oxidase (COI) gene between the Balkan (n = 4) and the Levantine (n = 2) populations. The Iranian population is described as a new species, Pachypasa hau...

Camera traps are an efficient means of biodiversity assessments, however, the employment of camera traps for the study of insects is still in its beginning. Accurate counting and recognition of flying insects are also of great importance in pest control. In this paper, we present a new method combining a time-lapse camera, and a light source, desig...

Mosquito monitoring traps (i.e., CDC light traps) are crucial tools for basic vector ecology research, risk assessment, and vector control programs. Unfortunately, they are expensive which is often an issue in projects conducted in developing countries. Therefore, it would be desirable to have reliable but inexpensive alternatives based on existing...
