Evaluation of a peridomestic mosquito trap for integration into an Aedes aegypti (Diptera: Culicidae) push-pull control strategy

Abstract

We determined the feasibility of using the BG-Sentinel™ mosquito trap (BGS) as the pull component in a push-pull strategy to reduce indoor biting by Aedes aegypti. This included evaluating varying numbers of traps (1-4) and mosquito release numbers (10, 25, 50, 100, 150, 200, and 250) on recapture rates under screen house conditions. Based on these variations in trap and mosquito numbers, release intervals were rotated through a completely randomized design with environmental factors (temperature, relative humidity, and light intensity) and monitored throughout each experiment. Data from four sampling time points (05:30, 09:30, 13:30, and 17:30) indicate a recapture range among treatments of 66-98%. Furthermore, 2-3 traps were as effective in recapturing mosquitoes as 4 traps for all mosquito release numbers. Time trends indicate Day 1 (the day the mosquitoes were released) as the "impact period" for recapture with peak numbers of marked mosquitoes collected at 09:30 or 4 h post-release. Information from this study will be used to guide the configuration of the BGS trap component of a push-pull vector control strategy currently in the proof-of-concept stage of development in

Evaluation of the Effectiveness of Mass Trapping With BG-Sentinel Traps for Dengue Vector Control: A Cluster Randomized Controlled Trial in Manaus, Brazil

“…However, further investigations and larger scale Þeld studies are necessary to further evaluate the effect of BGS mass trapping. A pushÐpull strategy where BGS is the pull component and spatial repellents or contact irritant chemicals are the push component, as recently proposed (Paz-Soldan et al 2011, Salazar et al 2012, also seems to be a promising approach. For further cluster-randomized trials of BGS mass trapping, a higher number of clusters should be included and serological investigations should be performed during periods of high dengue transmission to be able to further investigate the cost effectiveness of the strategy and the effect of the traps on disease transmission.…”

Mosquito Traps: An Innovative, Environmentally Friendly Technique to Control Mosquitoes

“…Detritus), they are more economical in spite of their relatively high maintenance costs, and they have a negligible impact on wildlife. Because they are located in human-inhabited areas, mosquito traps could provide a useful complementary tool for the control of container-inhabiting species such as Aedes albopictus and Aedes aegypti, which pose public health problems, and for which traditional integrated mosquito management approaches based on larvae control are inefficient [18,19,20]. Our experiment suggest that the observed 70% reduction in the mosquito nuisance could be increased by combining different olfactive lures, by optimizing the position of traps relative to environmental conditions, and by increasing trap numbers to improve the protecting belt effect.…”

Effect of Aedes aegypti exposure to spatial repellent chemicals on BG-Sentinel™ trap catches

“…The screen house measures 4 m (width) × 3.5 m (height) × 40 m (length) and is located on-site with the experimental huts [34]. The screen house is subdivided into four 10 m long cubicles using metal partitions, each with a space volume of 140 m 3 (Figure 1).…”

“…Previous studies have confirmed that the BGS trap effectively removes Ae. aegypti from a controlled environment [34]. However, the effects of exposure to repellents, or sublethal doses of insecticides, on BGS trap collections have not been previously evaluated.…”
