part_of adult behavioural process development of competence to respond to host cue effect of insemination IDOMAL:0002343 IDOMAL:0002343 The differences in responsiveness on host cues observed between virgin and inseminated females in some mosquito species. The flight-activity periodicities of captive females of a number of crepuscular/nocturnal species changed, and came to resemble the periodicities of man-biting activity in wild populations. One effect is on the phase of the flight-activity rhythm. It is suggested that a factor in the semen of the males of the autogenous strains suppressed blood-feeding by the nulliparous females of these strains. In some species, virgin females are less responsive to host cues than inseminated females. Another effect is the inhibition of responsiveness to host cues in females due to male accessory-gland secretion. idomal_namespace onset of delayed inhibition of responsiveness
