Abstract
Insects have a significant impact on human life, both positively and negatively. While insects pollinate at least two-thirds of all food consumed by humans, they also transmit diseases such as malaria and dengue through female mosquitoes of the Anopheles genus (malaria) and Aedes aegypti (dengue), causing hundreds of deaths each year. To mitigate the harmful effects of insects, researchers have developed mechanical, chemical, biological, and educational tools. However, the effectiveness of these tools depends on having prior knowledge of the timing, location, migrations, infestations, and populations of mosquito species. Insect detection and counting is typically performed using traps, which are regularly collected and manually analyzed. The main issue is that this method is expensive in terms of materials and human time and creates a delay between trap placement and inspection, which is enough time for a new mosquito to develop into an adult. Therefore, various mathematical models have been developed to identify the sounds of different mosquito species. Our study aimed to analyze and identify mosquito species through the sound signals emitted by their wings. We used signal processing techniques, specifically by analyzing the spectrogram of each processed audio, to carry out the identification process. The spectrogram was used as input for the mathematical model developed, and the corresponding mosquito species were identified based on the sound pattern of each examined audio signal. The spectrogram graphically represents the intensity of different frequencies in a sound signal over time. As a result, our study makes it possible to identify the species of each mosquito, enabling the monitoring of their populations and the identification of the species responsible for the transmission of certain diseases.
