Comparison of Mosquitoes Response to Different Diodes Wavelengths

Development of light-emitting diode (LED) trap for mosquitoes (Diptera: Culicidae) continues to be desirable over other types of electro-mechanical traps for the control of mosquito menace. It is a key menace to a large number of people and creatures around the world. This project further the development of mosquitoes LED-trap using recently developed low energy LED colours. Tests were conducted to determine most inviting wavelength to mosquitoes using available ten (10) different LED wavelengths. The project was done within the living area in Lagos State, Nigeria. The population density of attracted and captured mosquitoes was analysed. Six hundred and four (604) specimens were capture in the experiment, and three species were discovered. Amidst this superset were 19 male mosquitoes and the most prevalent species was female Culex mosquito followed by other insects. Male Culex mosquitoes and female Anopheles mosquitoes were the next respectively, while unidentified mosquitoes have the lowest count. The trap did not capture male Anopheles mosquito. The experiment shows that more Culex mosquitoes were attracted toward the purple LED than blue, green, pink and warm white while other light spectra such as white, red, yellow, green-yellow and orange were less attractive to mosquitoes. The low ratio of damage mosquitoes to identifiable mosquitoes shows that this passive is desirable compared to the Communicable Disease Centre (CDC) traps.
