In mating experiments, sensory blinding of the genital fold in females reduces their resistance behaviour towards males with asymmetrically manipulated titillators. Data presented as a percentage bar. In both experiments, the females were mated with virgin males that had one titillator (t1) shortened. First experiment (treatment at remating): females were tested before and after mechanical blocking of mechanoreceptors of the genital fold with a UV-hardening glue cap. Second experiment (treatment at initial mating): females were tested directly after application of pymetrozine (5 µl, 10⁻³ mol l⁻¹) for 5 min on their genital fold and then again 24 h after the pymetrozine treatment. Fisher's exact tests: *p < 0.05. (Online version in colour.)
