A Precise and Autonomous System for the Detection of Insect Emergence Patterns Meghan M. Bennett1,2, Joseph P. Rinehart3, George D. Yocum3, Ian Yocum3 1Department of Biological Sciences, North Dakota State University, 2School of Life Sciences, Arizona State University, 3Red River Valley Agricultural Research Center, USDA-ARS Measurement of insect emergence patterns requires precision. Existing systems are only semi-automated and sample size is limited. We addressed these issues by designing a system using microcontrollers to precisely measure the time of emergence of large numbers of emerging insects.
