COMPARISON OF EFFECTIVENESS OF THE BG-TRAP METHOD AND HUMAN-BAITED DOUBLE NET TRAP METHOD FOR MONITORING DENGUE FEVER VECTOR AEDES ALBOPICTUS
Journal Title: Acta Parasitologica et Medica Entomologica Sinica - Year 2024, Vol 31, Issue 1
Abstract
[Objective] The effectiveness of the BG-Trap and human-baited double net trap (HDN) methods in monitoring Aedes albopictus were compared to assess the potential use of the BG-Trap method for dengue fever vector monitoring program. These findings would also provide a reference basis for formulating more effective dengue fever prevention and control strategies. [Methods] The study was conducted at six outdoor monitoring sites in three cities in Jiangsu Province in August and September, following a 3-d monitoring plan. Both traps were evaluated simultaneously at three time slots each day (16:00 -16:30, 17:00 -17:30, and 18:00 -18:30). [Results] Both the BG-Trap and HDN methods effectively captured female Ae. albopictus. The proportion of Ae. albopictus captured by the HDN method was higher than that captured by the BG-Trap method (χ2=0.162, P=0.687), with no statistically significant differences in the composition ratio of male/female between the two methods(χ2=0.162, P=0.687). The average density index of Ae. albopictus for the BG-Trap method was 7.85±5.23/h, significantly lower than that of the HDN method at 27.04±13.86/h under the same sampling sites (t=6.73, P<0.001). [Conclusion] These results suggest that the BG\|Trap method is less effective than the HDN method in Ae. albopictus monitoring. Further research is required to determine the applicability of this method for dengue fever vector monitoring.
