Modulated frequencies vary within female’s wingbeat range (500–650 Hz) best attract males at 75–79 dB volume and in combination with black target.
Males increase their response to acoustic stimulation up to 4 days of age and then show a continuous and progressive decline of their sound responsiveness.
A prototype sound trap producing the most effective sound stimuli proven at laboratory conditions was proposed and tested in the field.
The use of variable sound stimuli appears a promising prospect to increase the capture rate of A. albopictus males in dedicated or in already existing mosquito traps.
