ABSTRACT
Aedes mosquitoes are the primary vectors of dengue. Ovitraps are widely used for the early detection and monitoring of Aedes populations. Meteorological factors, such as temperature and rainfall, play a crucial role in influencing Aades population dynamics. This study investigates the relationship between rainfall and temperature with the ovitrap index and mosquito egg counts in Bandar Baru Pasir Puteh, Kelantan, Malaysia. A cross-sectional study was conducted aver two years (2023-2024) deploying 3350 ovitraps. Meteorological data were obtained from the Meteorological Department of Malaysia. The dependent variables were the ovitap index and mosquito egg counts. Descriptive and correlation analyses were conducted at a significance level of p < 0.06 Aedes albopictus was found to be more prevalent than Aedes aegypti, with 18.458 and 6,689 larvae recorded, respectively. A moderate positive correlation was observed between the ovitrap index and temperature (r = 0.31, p = 0.0046), indicating that higher temperatures are associated with increased Aedes populations. However, no significant correlation was found between the evitrap index and rainfall (r = 0.05, p = 0.08). Egg counts showed a weak negative correlation with temperature (r = -0.18, p = 152 x 10") and no significant relationship with rainfall (r=-0.09, p=2.29 x 10). Ultimately, temperature was shown to significantly influence Andes populations, demonstrating a weak positive relationship with the ovitrap index and a negative correlation with egg counts. Rainfall had a minimal impact on mosquito abundance and egg production, underscoring the importance of temperature monitoring for effective vector control
