Evaluating the synergistic effects of anisaldehyde and other three widely recognized mosquito-attracting agents in urban parks

This study investigates the mosquito-attracting effects of anisaldehyde in conjunction with other three widely recognized mosquito attractants in urban parks. The results indicate that the combinations of ultraviolet light + CO2 and ultraviolet light + anisaldehyde were particularly effective in attracting mosquitoes, with the number of mosquitoes attracted per trap reaching 182.1 and 74.9, respectively. While the substantial broad-spectrum for 1-octen-3-ol was lower than that of anisaldehyde, it exhibited superior mosquito-specific attraction, rendering it suitable for monitoring mosquito density. Conversely, anisaldehyde is more optimal as a mosquito-killing attractant. The 5 g dosage of the anisaldehyde-ethylene vinyl acetate sustained-release agent (AEVASRA) significantly enhanced the response of mosquitoes to the trapping device under outdoor conditions, with an effective duration of 40 days. Consequently, it may serve as a long-term and stable mosquito attractant. The evaluation of the synergistic effects of multiple attraction agents has the potential to provide a theoretical basis for the efficient development of mosquito trapping devices, and for the prevention and control of mosquitoes.
