A set of data acquisition and analysis system of insect acoustic signal (DAASIAS)with friendly interface, simple operation and multifunction was developed. DAASIAS could sample and analyze insect acoustic signals in real time. By using DAASIAS, both observing insect behavior and analyzing signal could be conducted at the same time. DAASIAS was applied firstly in sampling and analyzing the brown planthopper signals and results showed that DAASIAS was steady and provided a powerful platform for deeply studying insect sound communication.
