“…quinquefasciatus , which contradicts our original prediction, because BG lures consist of lactic acid, caproic acid and ammonium bicarbonate simulated human odorants that are thought to be more attractive to female mosquitoes. Similar results have also been reported from studies conducted in Brazil and Kenya [ 31 , 32 ]. However, research from America showed that the ratio of male-to-female Ae.…”

BackgroundThe surveillance of vector mosquitoes is important for the control of mosquito-borne diseases. To identify a suitable surveillance tool for the adult dengue vector Aedes albopictus, the efficacy of the BG-Sentinel trap, CDC light trap and Mosquito-oviposition trap (MOT) on the capture of vector mosquitoes were comparatively evaluated in this study.MethodsThe capture efficiencies of the BG-Sentinel trap, CDC light trap and Mosquito-oviposition trap for common vector mosquitoes were tested in a laboratory setting, through the release-recapture method, and at two field sites of Guangzhou, China from June 2013 to May 2014. The captured mosquitoes were counted, species identified and compared among the three traps on the basis of species.ResultsIn the release-recapture experiments in a laboratory setting, the BG-Sentinel trap caught significantly more Aedes albopictus and Culex quinquefasciatus than the CDC light trap and Mosquito-ovitrap, except for Anopheles sinensis. The BG-Sentinel trap had a higher efficacy in capturing female rather than male Ae. albopictus and Cx. quinquefasciatus, but the capture in CDC light traps displayed no significant differences. In the field trial, BG-Sentinel traps collected more Aedes albopictus than CDC light traps and MOTs collected in both urban and suburban areas. The BG-Sentinel trap was more sensitive for monitoring the population density of Aedes albopictus than the CDC light trap and MOT during the peak months of the year 2013. However, on an average, CDC light traps captured significantly more Cx. quinquefasciatus than BG-Sentinel traps. The population dynamics of Cx. quinquefasciatus displayed a significant seasonal variation, with the lowest numbers in the middle of the year.ConclusionsThis study indicates that the BG-Sentinel trap is more effective than the commonly used CDC light trap and MOT in sampling adult Aedes albopictus and Culex quinquefasciatus. We recommend its use in the surveillance of dengue vector mosquitoes in China.Electronic supplementary materialThe online version of this article (doi:10.1186/s13071-016-1724-x) contains supplementary material, which is available to authorized users.

“…BGS traps were unbaited (no CO 2 or BG-Lure) and operated continuously. The decision to trap without the BG-lure or CO 2 was based on previous reports indicating their addition at substantial costs does not significantly increase male capture rates over unbaited BGS traps [ 32 , 33 ]. All Ae .…”

A low-cost, battery-powered acoustic trap for surveilling male Aedes aegypti during rear-and-release operations

et al. 2018

The Aedes aegypti mosquito is a primary vector of several serious arboviruses throughout the world and is therefore of great concern to many public health organizations. With vector control methodology pivoting towards rearing and releasing large numbers of genetically modified, sterilized, or Wolbachia-infected male mosquitoes to control vector populations, economical surveillance methods for release tracking becomes increasingly necessary. Previous work has identified that male Ae. aegypti are attracted to female wingbeat frequencies and can be captured through artificial playback of these frequencies, but the tested systems are cost-prohibitive for wide-scale monitoring. Thus, we have developed a simple, low-cost, battery-powered, microcontroller-based sound lure which mimics the wingbeat frequency of female Ae. aegypti, thereby attracting males. We then tested the efficacy of this lure in combination with a passive (non-powered) gravid Aedes trap (GAT) against the current gold-standard, the Biogents Sentinel (BGS) trap, which requires main power (household power) and costs several times what the GAT does. Capture rates of male Ae. aegypti in sound-baited GATs (Sound-GATs) in these field tests were comparable to that of the BGS with no inhibitory effects of sound playback on female capture. We conclude that the Sound-GAT is an effective replacement of the costly BGS for surveillance of male Ae. aegypti mosquitoes, particularly in the developing countries where funding is limited, and has the potential to be adapted to target males of other medically important species.

“…These included: (i) the CO 2 - baited EVS trap ( Rohe & Fall, 1979 ), (ii) oviposition cups ( Barbosa et al , 2010 ; Furlow & Young, 1970 ), (iii) CO 2 - baited BG Sentinel (BGS) trap ( www.bg-sentinel.com - without octenol attractant) and (iv) Autocidal Gravid Oviposition trap (AGO-B) ( MacKay et al , 2013 ). The decision to use CO 2 with the BGS was based on a study by de Ázara et al (2013) that showed that more females were collected in BGS baited with CO 2 than without.…”

Surveillance, insecticide resistance and control of an invasive Aedes aegypti (Diptera: Culicidae) population in California

The invasion and subsequent establishment in California of in Aedes aegypti 2013 has created new challenges for local mosquito abatement and vector control districts. Studies were undertaken to identify effective and economical strategies to monitor the abundance and spread of this mosquito species as well as for its control. Overall, BG Sentinel (BGS) traps were found to be the most sensitive trap type to measure abundance and spread into new locations. Autocidal-Gravid-Ovitraps (AGO-B), when placed at a site for a week, performed equally to BGS in detecting the presence of female Ae. aegypti. Considering operational cost and our findings, we recommend use of BGS traps for surveillance in response to service requests especially in locations outside the known infestation area. We recommend AGO-Bs be placed at fixed sites, cleared and processed once a week to monitor mosquito abundance within a known infestation area. Long-term high density placements of AGO-Bs were found to show promise as an environmentally friendly trap-kill control strategy. California were found to be homozygous for the V1016I Ae. aegypti mutation in the voltage gated sodium channel gene, which is implicated to be involved in insecticide resistance. This strain originating from Clovis, California was resistant to some pyrethroids but not to deltamethrin in bottle bio-assays. Sentinel cage ultra-low-volume (ULV) trials using a new formulation of deltamethrin (DeltaGard®) demonstrated that it provided some control (average of 56% death in sentinel cages in a 91.4 m spray swath) after a single truck mounted aerial ULV application in residential areas.This article is included in the Zika & Arbovirus Amendments from Version 2Dr. Lozano-Fuentes' comments were already addressed in v2.The following changes are made to incorporate Dr. Xue's comment:1. We added GPS co-ordinates for study site.2. We added blood resource and % sugar feeding for adult mosquitoes.3. We deleted Culex from this paper.4. We added ULV truck speed and flowing rate.5. We added the information about vegetation and any barrier objects for the trials in residential area.
