Fig. 4: AaOr31-mediated (E)-β-farnesene (EBF)/pyrethrum repellency in Ae. aegypti.
From: A dual-target molecular mechanism of pyrethrum repellency against mosquitoes
a Representative SSR traces from short blunt-tipped (sbt)-1 sensilla in Rockefeller (wild-type) and AaOr31−/− mosquitoes in response to EBF (n = 10 sensilla for Rockefeller and n = 7 sensilla for AaOr31−/−), (±)-citronellal (n = 10 sensilla for Rockefeller and n = 8 sensilla for AaOr31−/−), geranyl acetate (n = 10 sensilla for Rockefeller and n = 8 sensilla for AaOr31−/−) and pyrethrum (n = 10 sensilla for Rockefeller and n = 8 sensilla for AaOr31−/−) at 10−2 dilution. b Repellency in AaOr31−/− compared with that of Rockefeller mosquitoes to EBF (t = 3.38, df = 11, P = 0.0061; n = 6 cages for AaOr31−/− and n = 7 cages for Rockefeller from 3 batches of mosquitoes), (±)-citronellal (t = 2.26, df = 16, P = 0.0384, n = 9 cages for AaOr31−/− and n = 9 cages for Rockefeller from 4 batches of mosquitoes), geranyl acetate (U = 8, P = 0.008, n = 8 cages for Rockefeller, n = 9 cages for AaOr31−/− from 4 batches of mosquitoes) and pyrethrum (U = 1, P = 0.001, n = 6 cages for AaOr31−/−, n = 8 cages for Rockefeller from 3 batches of mosquitoes) at 10−2 dilution. Two-tailed unpaired student’s t-test or two-tailed Mann–Whitney Rank Sum test was used to compare each of two sets of data. Data are plotted as mean ± s.e.m. and dots denote the value of each repeat.
