Abstract

Objective To determine and evaluate the effect of the BG-home mosquito trap for Aedes albopictus, Ae. aegypti, and Culex pipiens quinquefasciatus by laboratory simulation experiments. Methods In a standard glass test room of 28 m3 in volume, mosquito trapping experiments were performed using BG-home, in the presence or absence of blue light, in combination with each of the attractants BG-homescent, BG-sweetscent, and Yousida (Qianyiduo Co., Ltd., Foshan, China) or no attractant. After 24 hours, we counted the number of captured mosquitoes in the experimental groups and the number of dead mosquito in the blank control group. The capture rate was corrected using the Abbott formula to evaluate the trapping effect. Results The mean capture rates of Ae. albopictus, Ae. aegypti, and Cx. pipiens quinquefasciatus were: 94.00%, 93.33%, and 81.27%, respectively, by BG-homescent with blue light; 90.97%, 90.00%, and 75.67%, respectively, by BG-homescent without blue light; 86.53%, 80.67%, and 70.57%, respectively, by BG-sweetscent with blue light; 83.50%, 76.67%, and 67.00%, respectively, by BG-sweetscent without blue light; 88.47%, 66.00%, and 59.67%, respectively, by Yousida with blue light; 84.75%, 63.33%, and 52.33%, respectively, by Yousida without blue light; 38.00%, 22.67%, and 62.33%, respectively, by attractant-free BG-home with blue light; 35.33%, 20.00%, and 22.33%, respectively, by attractant-free BG-home without blue light. Conclusion With the above three attractants, BG-home had the best trapping effect for Ae. albopictus, followed by Ae. aegypti. Blue light significantly enhanced its trapping effect for Cx. pipiens quinquefasciatus without the use of attractants. BG-home combined with attractants shows a good trapping effect for common mosquitoes, especially Aedes species, which can be used for mosquito surveillance and control in dengue prevention and control.
