Assessment of Indoor Resting Density of Female Mosquitoes in Dutse, Jigawa State, Nigeria: Implications for Disease Transmission and Community-Based Mosquito Control Measures

Study’s Excerpt/Novelty This study presents insights into the seasonal variations in Indoor Resting Density (IRD) of female mosquitoes in Dutse L.G.A., Jigawa State, providing critical data for targeted vector control interventions. By employing the Pythrum Spray Caught method across three communities over seven months, it uniquely identifies the optimal timing for insecticide spraying, particularly in April, when the IRD exceeds the epidemic threshold. The research underscores the necessity of community involvement in mosquito control measures, paving the way for more effective and localized vector management strategies. Full Abstract Mosquito is a major vector of humans and other animals globally, especially in Africa. This study assessed female mosquitoes' Indoor Resting Density (IRD) in Dutse L.G.A., Jigawa State. Mosquitoes were collected using the Pythrum Spray Caught method from three communities (Gurungu, Baranda, and Warwade) for seven months (April to October 2022). The highest IRD of female Anopheles was recorded in September at Baranda (33.3) and the lowest IRD at Gurungu (0.0) in June. The highest IRD of Female Culex was recorded in July at Gurungu (13.7), while the lowest was recorded in June at Baranda (0) and Warwade. The findings of this study revealed the idle spraying time of insecticide in all the study sites, which was found to be April because the IRD was beyond the normal (0.05)per house, which was related to epidemic transmission of the diseases. I recommended further study on community involvement in mosquito control measures.
