Abstract: Efficacious traps for anthropophilic anophelines are urgently required. We compared the efficacy between the human double net trap (HDNT) and human landing collection (HLC) methods in capturing Minimus complex under the semifield screen house system (SFS). Transfluthrin-treat fabric (TFT) material was subsequently monitored on two host-seeking malaria vectors of the Minimus complex. Mean density of Anopheles harrisoni was significantly lower in HDNT (15.5 per night, 95% CI: 12.48–18.52) relative to HLC (25.32 per night, 95% CI: 22.28–28.36), p<0.0001. Similarly, the mean density of a laboratory strain of Anopheles minimus recaptured in HDNT was significantly lower (37.87 per night, 95% CI: 34.62–41.11) relative to HLC (56.4 per night, 95% CI 55.37–57.43), p<0.0001. TFT-treated jute (TFT-J) significantly reduced human landing rate (HLR) of mosquito with the Odds Ratio (OR) at 0.27 (95% CI: 0.10-0.74), p=0.011. However, no significant reduction was observed for TFT-treated cotton (TFT-C) with the OR at 0.67 (95% CI: 0.24-1.82), p=0.43 relative to control. Blood feeding was significantly lower in TFT-J (12.45%), 95% CI: 2.04-22.85, p=0.029 and TFT-C (13%), 95% CI: 0.99-26.84, p=0.016) relative to control. The larval emergence rate was significantly reduced in TFT-J (49.5%) (95% CI: 21.74-77.26, p=0.029 and TFTC (40.2%) (95% CI: 17.21-63.19), p=0.008) relative to control. HDNT was not significantly successful nor correlated with HLC, suggesting that it is not an alternative method to HLC for An. minimus and An. harrisoni trapping in the SFS. TFT-J significantly reduced the landing, blood feeding, and fertility rate of An. minimus. Further studies are needed to evaluate different formulations of TFT containing repellent products against various mosquito species and a real-world community setting should be part of the evaluation scheme.
