Although male accessory gland substances modulate female receptivity in most mosquito genera that have been studied, they are not active in the development of sexual refractoriness in the malaria vectors, Anopheles gambiae or Anopheles albimanus. Neither the implantation of male accessory glands nor the injection of gland homogenates affected the insemination rate of unmated females. Similarly, portions of the male genital tract and spermathecae from mated females were also inactive when introduced into these females. Interruption of nervous transmission from the brain reduced the tendency of females to become inseminated and removal of the terminal abdominal ganglion completely abolished insemination. Oviposition behavior did not occur unless the spermatheca containing sperm was present, suggesting that this may be the mechanism that mediates the switchover to mated behavior.
