![]() ![]() the human-baited double net (HDN) and mosquito electrocuting grid trap (MET). ![]() To address these shortcomings, new ways of safely carrying out HLCs have been proposed and tested, e.g. For example, this technique: (i) is expensive in large-scale operations (ii) exposes humans to mosquito bites and thus increases the risk of infections in field settings (iii) is labor-intensive and (iv) needs close supervision, high skills and motivation. However, using humans directly as bait to collect mosquitoes has multiple limitations. The human landing catch (HLC) is the most direct and scalable method for measuring human biting rates and is regarded as the gold standard for collecting host-seeking mosquitoes. A major setback for many of the existing techniques is poor scalability due to their physical structure and cost. ![]() Some of the traps have also been considered as control intervention when used as mosquito trapping. Various traps have been developed and used for mosquito sampling and surveillance, often for experimental studies but also for programmatic purposes. For malaria and other vector-bone diseases, surveillance plays a major role in: (i) tracking transmission (ii) assessing susceptibility of vectors to interventions (iii) measuring receptivity in specific locations and (iv) predicting disease outbreaks. To operationalize this agenda, endemic countries need low-cost and scalable monitoring tools, as well as a simplified set of indicators for surveillance. ![]() The World Health Organization, through its Global Technical Strategy for Malaria Elimination (GTS) and Global Vector Control Response initiative (GVCR), has called for strengthening and integration of surveillance as a core component of strategies against mosquito-borne diseases. However, we recommend additional field tests to validate these findings in multiple settings and to assess the potential of LEDs to attract non-target organisms, especially outdoors. We conclude that this trap may have potential for mosquito surveillance. The trap can be used indoors near human-occupied nets, or outdoors, in which case additional CO 2 improves catches. The Mosclean trap was more productive in sampling mosquitoes indoors compared to outdoors. Its efficacy was comparable to and in some instances better than traps commonly used for vector surveillance. The UV LED trap (Mosclean trap) was efficacious for sampling Anopheles and Culex mosquitoes. In comparison, the females caught by CDC-light traps were 43.9% parous and 92.8% inseminated. arabiensis females caught by Mosclean traps were parous (63.6%) and inseminated (89.8%). It was also better at trapping malaria vectors compared to both Suna and BG-Sentinel traps, and was more efficient in collecting mosquitoes indoors than outdoors. arabiensis and twice as many Culex mosquitoes as CDC-light traps. Under field settings, Mosclean traps caught equal numbers of An. Similar results were obtained when traps were tested individually in the chambers. When simultaneously placed inside the same semi-field chamber, the Mosclean trap caught twice as many Anopheles arabiensis as the CDC-light trap, and equal numbers to HLCs. The Mosclean trap was compared to commonly used techniques, namely CDC-light traps, human landing catches (HLCs), BG-Sentinel traps and Suna traps. The study was conducted in controlled semi-field settings and in field conditions in rural south-eastern Tanzania. This study evaluated the efficacy of a new ultraviolet LED trap (Mosclean) against standard mosquito collection methods. Light-emitting diodes (LEDs) are increasingly used in mosquito traps because they improve energy efficiency and battery longevity relative to incandescent bulbs. Improved surveillance techniques are required to accelerate efforts against major arthropod-borne diseases such as malaria, dengue, filariasis, Zika and yellow-fever. ![]()
