Control de Copitarsia decolora en cultivos de flores mediante la emisión de frecuencias.

One of the plagues intercepted by the Health's supervisory Service of Animals and Plants (APHIS) of United States in the exports of some species of flowers of court of Colombia is Copitarsia spp. The present study evaluated the evasive answer of Copitarsia decolora (Lepidoptera: Noctuidae) by means of the simulation of calls of echo-location of bats as a proposal for the handling of flowers in post-harvest rooms, under controlled conditions. The shapes of the signs of echo-location of the bats were taken from some samples of insectivorous quirópteros and were simulated by means of the software "Sound Ruler", determining the fundamental parameters that characterize the calls, such as their width, frequency and forms, among others; starting from this characterization, an electronic system was designed and built to reproduce the echo-location calls. The system was tried, emitting the reproduced signal toward a sample of Copitarsia, and an evasive reaction was observed as result of this signal. [ABSTRACT FROM AUTHOR]
