Background: Insecticide resistance and vector-feeding behavior changes have recently challenged malaria vector control.All this causes the vectors to forfeit the benefits of insecticide-based control tools.Searching for other control tools for immediate and future use is important.This study evaluated the gravid Anopheles gambiae s.s.

response to habitat water with a background of different colors.Methods: Green, black, red, and blue were selected as background colors based on previous literature searches.The experiments were set up in a Latin square with drops out of colors and fewer eggs.Fresh habitat water was used on each experimental day.The egg Storage Basket count was done for two consecutive days.

Results: The results of this study showed that the position of the oviposition substrate had no influence on gravid mosquito response.The highest number of eggs Over-Ear was laid on the green background in all stages of the experiments.The interaction of experimental days, position, and the number of eggs laid had no statistical significance.Conclusion: The findings of this study have shown that the habitat water coupled with a green-colored background influences most oviposition site selection by gravid An.gambiae.

This shows that green-colored background can be integrated into the gravid mosquito traps for efficiency increase.
