PAZ, Hernán et al. Control of Copitarsia Decolora in Flower Growing by Issuing Frequencies. rev.ing. [online]. 2008, n.27, pp.17-26. ISSN 0121-4993.
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 echolocation of bats like proposal for the handling in rooms of post-harvest of flowers, under controlled conditions. The shapes of the signs of echo-location of the bats took of some samples of insectivorous quirópteros and were simulated by means of the software "Sound Ruler", determining the fundamental parameters that characterize the calls as their width, frequency and it forms, between other ones; starting from this characterization, it was designed and built an electronic system able to reproduce the echo-location calls. The system was tried, emitting the sign reproduced toward a sample of Copitarsia, and an evasive reaction was observed in front of this sign.
