Objective To investigate the efficacy of three mosquito attractants (Attractant A, B, and C), carbon dioxide (CO2) at different flow rates and attractant combined with CO2in attracting Aedes albopictus, to screen out the optimal combination, and to provide a scientific basis for the application of chemical pheromone monitor in the field work of Ae. albopictus surveillance. Methods A remote-controlled chemical pheromone mosquito trap monitor was used to perform the trapping test. A total of 200 Ae. albopictus mosquitoes were placed in the simulation room, and the trapping test was conducted for the three mosquito attractants, CO2 at different flow rates, and attractant combined with CO2, and efficacy was observed after 24 hours. The Chi-square test and the logistic regression analysis were used to compare and analyze the efficacy of different attractants and CO2 flow rates in trapping Ae. albopictus. Results CO2 at a flow rate of 80, 150, and 200 ml/min had mean trapping rates of 50.42%, 64.67%, and 74.33%, respectively, and attractant A, B, and C had mean trapping rates of 66.40%, 70.30%, and 53.00%, respectively. Attractant A combined with CO2 at a flow rate of 80, 150, and 200 ml/min had mean trapping rates of 66.67%, 67.33%, and 79.67%, respectively, and attractant B combined with CO2 at a flow rate of 80, 150, and 200 ml/min had mean trapping rates of 70.67%, 78.67%, and 82.33%, respectively. Conclusion In the simulation test, the remote-controlled chemical pheromone mosquito trap monitor with the application of mosquito attractant and CO2 has a marked effect in trapping Ae. albopictus, which is better than the use of attractant or CO2 alone. The surveillance method can be used for field surveillance and control of vector Aedes mosquitoes.
