Evaluating the synergistic effects of anisaldehyde and three other widely recognized mosquito-attracting agents in urban parks
摘要
Urban parks, as areas with frequent human activities, are also high-risk zones for mosquito breeding. Implementing mosquito control measures in these spaces is crucial for safeguarding public health. This study investigates the mosquito-attracting effects of anisaldehyde in conjunction with three other 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 182.33 and 74.67, respectively. Although the broad-spectrum insect-attracting property (BSIAP) of 1-octen-3-ol was lower than that of anisaldehyde, it demonstrated greater specificity in attracting mosquitoes, making it a more suitable candidate for monitoring mosquito population 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 combined effects of multiple attraction agents have the potential to provide a theoretical basis for the efficient development of mosquito trapping devices, and for the prevention and control of mosquitoes.
