The Animal and Plant Health Inspection Service of the United States has identified Copitarsia decolora (Lepidoptera: Noctuidae) as a pest in freshly cut flowers exported from Colombia. This chapter discusses the development of an electronic system designed to simulate bat echolocation calls. Using the “Sound Ruler” software, key parameters like amplitude, frequency, and call shape were analyzed to characterize bat echolocation signals. Based on this data, an electronic device was created to replicate these signals. The behavior of Copitarsia decolora was studied to evaluate the effectiveness of using bat echolocation signals for pest management. During trials, moths exhibited a clear evasive response to the simulated signals, demonstrating the method’s effectiveness in inducing a natural defense response and reducing pest incidence on cut flowers. This system not only enhances the control of Copitarsia decolora but also contributes to agricultural sustainability by reducing the reliance on synthetic pesticides. The use of echolocation call simulation reduces environmental impact and promotes sustainable development. The chapter is divided into two main parts: the first covers the biology of bats and Copitarsia decolora, focusing on ethological control methods and highlighting bats as predators. The second part details the characterization of echolocation calls, the design and construction of the electronic system, and the results of lab trials, circuit adjustments, and semi-controlled validation.
