Vector surveillance using sticky ovitraps (50) is essential for evaluating dengue vector persistence during and after outbreak response operations. This study assessed the effectiveness of outbreak control activities by comparing the Sticky Ovitrap Index (SO) between active outbreak and post-outbreak phases in village localities of Melaka Tengah District. A longitudinal entomological surveillance study was conducted across 16 dengue outbreak village localities. SD deployment was performed systematically over four consecutive surveilance rounds. Rounds 1 and 2 represented the active outbreak phase, while Rounds 3 and 4 represented the post-outbreak phase. Mean SOI values were calculated and stratified into risk categories: low (<10), medium (010-0.30), and high (>0.30). A paired-samples t-test was applied to determine significant differences between the two operational phases. Statistical analysis demonstrated no significant reduction in vector density after the outbreaks were declared resolved (115)=-1282, p = 0.219). The overall mean S01 increased from 0.33 during the outbreak phase to 0.37 post-outbreak. High-risk localities expanded from 10 to 13 areas, representing 81.3% of the evaluated villages. Kampung Paya ikan recorded the highest increase (37.0%), reaching a peak SOI of 0.60. No locality successfully transitioned into the low-risk category. The persistently high Aedes deraity indicates that conventional adulticiding provides only temporary control without eliminating breeding sites. Strengthening integrated vector management (IVM) through multi-agency collaboration, targeted larviciding. environmental management, and community empowerment is crucial to prevent recurrent dengue transmission in village localities of Melaka Tengah.
