There is an Article that says that the experiments done with low and
high frecuencies failed:
http://bugjammer.com/reports/coro/index.htm
/"Another type of electronic mosquito repeller is claimed to "mimic
perfectly the sound of dragon-flies, natural enemies of mosquitoes". In
this case Schreiber et al (1991) measured that the frequency emitted was
30 Hz, much lower than the minimum frequency reported for the mosquito
wing beat (Clements 1999). Schreiber et al (1991) with field and
laboratory tests in Florida and Curtis (1994) with laboratory trials in
London, England also_* report negative results of this device *_in
eliciting a repellent effect on mosquito females. "
