Fig. 2From: Enhancing attraction of the vector mosquito Aedes albopictus by using a novel synthetic odorant blendComparison of the attractancies exhibited by different concentrations of each compound against female Aedes albopictus mosquitoes. a Ammonia. b l-Lactic acid. c Hexanoic acid. d 3-Methyl-1-butanol. e Cyclopentanone. f 1-Octen-3-ol. g 6-Methyl-5-hepten-2-one. Orientation index = (Nt − Nc)/T, where Nt is the number of mosquitoes trapped in the treatment chamber, Nc is the number of mosquitoes trapped in the control chamber and T is the total number of test mosquitoes. Bars represent the means ± SE (n = 6–10)Back to article page
