Assessing AedesTech mosquito home system on yellow fever mosquito Aedes aegypti (Linnaeus) in Northern Malaysia

This research evaluated the AedesTech Mosquito Home System (AMHS), an ovitrap employing autodissemination with pyriproxyfen, to monitor and manage mosquito populations. It involved 3 studies of the AMHS: a baseline study, an effectiveness study, and an autodissemination study on Aedes (Diptera: Culicidae) mosquitoes. Forty AHMS units filled with water were deployed for the baseline study. During the effectiveness study, 40 untreated AMHS units with water were placed alongside 40 AMHS units treated with Mosquito Home Aqua (MHAQ) solution, the retail solution used for AMHS. The autodissemination study featured 40 AMHS units treated with MHAQ alongside 40 control AMHS units without MHAQ, together with 25 Aedes aegypti (Linnaeus) larvae. Notably, treated traps in the effectiveness study exhibited a significant reduction in the Ovitrap Index (OI) compared to the baseline traps in the baseline study. The effectiveness study validated AMHS's efficacy, with treated traps displaying a significantly lower OI than untreated counterparts (P < 0.05). The study also showed a decrease in the percentage of egg hatching and percentage of adult emergence in treated traps compared to untreated traps. Autodissemination was evident, marked by a significant percentage of adult emergence decrease of Ae. aegypti larvae, without affecting sex ratios. It strongly suggests that AMHS can effectively reduce Aedes populations through direct contact and autodissemination without affecting sex ratios.
