Effects of Overripe Banana Processing Techniques on the Chemical Composition and Attractancy to Aedes aegypti and Aedes albopictus

Syrup-concentrated overripe banana extracts are most attractive to both Aedes aegypti and Aedes albopictus, with PI = 0.58 ± 0.17 and 0.58 ± 0.14.

• Why it matters: Mosquito insecticide resistance and limited knowledge of how fruit processing affects ATSB attractants motivate testing production methods that change banana chemistry and odor cues.
• What they did: Overripe Musa acuminata extracts made by liquid extraction, syrup concentration, or freeze-drying were loaded into hydrogel beads and compared in dual-choice olfactometer assays, with GC-MS and enzymatic sugar profiling.
• The result: All extracts attracted mosquitoes more than the 10% sucrose control; freeze-dried retained the greatest VOC diversity, while syrup showed VOC degradation but produced Maillard reaction products, and both syrup and freeze-dried contained sucrose 0.35–0.57 g/100g plus high glucose, fructose, and maltose.
