Deltamethrin contact irritancy in susceptible laboratory Anopheles sinensis mosquitoes. Flying time (a) and number of takeoff (b) of female An. sinensis during a 3-min exposure to DTNs or UTNs in a modified WHO cone bioassay. c The first takeoffs from DTNs occurred early; takeoffs from UTN controls occurred much later in the 3-min interval. Blue dots represent the first takeoffs from UTNs; red dots represent the first takeoffs from DTNs. d Time until first takeoff of An. sinensis exposed to a DTN or a UTN. N = the number of mosquitoes. Error bars indicate standard errors *p < 0.05, **p < 0.01, Mann–Whitney U test
