Potential of unmanned aerial sampling for monitoring insect populations in rice fields
Keywords:
insect sampling, unmanned aerial vehicle, droneAbstract
Conventionally, sampling for insects has been limited to the ground level or low altitudes. Recent progress in unmanned aerial vehicles has made it more feasible to use this technique for aerial sampling of insect populations. In this study, we developed a rotary-wing unmanned aerial vehicle with remote-controlled insect net openings that allows serial sampling at designated altitudes. A total of 21 flights using the unmanned aerial vehicle system captured 251 insects in 6 orders and 22 families at 5, 10, 50, and 100 m above rice fields in South Korea. The results of this study demonstrate that the aerial sampling can collect diverse pest and beneficial insects above rice fields and demonstrate a promising alternative to conventional sampling methods.
Sumario
Convencionalmente, el muestreo de insectos se ha limitado al nivel del suelo o a bajas altitudes. El progreso reciente en vehículos aéreos no tripulados ha hecho que sea más factible utilizar esta técnica para el muestreo aéreo de poblaciones de insectos. En este estudio, desarrollamos un vehículo aéreo no tripulado de ala giratoria con aberturas de red de insectos controladas a distancia que permite el muestreo en serie a altitudes designadas. Un total de 21 vuelos que utilizan el sistema de vehículo aéreo no tripulado capturaron 251 insectos en 6 órdenes y 22 familias a 5, 10, 50 y 100 m sobre el campo de arroz en Corea del Sur. Los resultados de este estudio demuestran que el muestreo aéreo puede recolectar diversas plagas e insectos beneficiosos por encima del campo de arroz y demuestra una alternativa prometedora a los métodos de muestreo convencionales.
