Roth's (1964b) demonstration that the suppression of female receptivity results from the physical insertion of the spermatophore into the bursa in N. cinerea has been interpreted as evidence that males force monandry on females during their first reproductive cycle. The bursa and the brood sac are in close physical proximity within the female genital tract. This serves as the basis for the argument that males are co-opting the physiological mechanism evolved to suppress female receptivity...
