Spermatophore formation and regulation of egg maturation and oviposition in female Heliothis virescens by the male

This study was undertaken, using various surgical manipulations, to examine the role and functions of accessory sex glands and testes in Heliothis virescens in spermatophore formation and stimulation of egg maturation in mated females.

Description
Summary:This study was undertaken, using various surgical manipulations, to examine the role and functions of accessory sex glands and testes in Heliothis virescens in spermatophore formation and stimulation of egg maturation in mated females. Normal females mated to accessory sex glandectomized (−ASG) males produced fewer eggs and retained most of their eggs in ovarioles compared with females mated to sham-operated (+ASG) or normal males. The ASG are the source of the components for spermatophore formation in H. virescens. Females mated to castrated (−Testes) males showed similar pattern of egg production as did females mated to −ASG males. Females mated to −Testes males and those mated to sham-operated (+Testes) or normal males were found to have spermatophore in the bursa after uncoupling. Normal females mated to allatectomized (−CA) males developed similar numbers of total eggs as did females mated to sham-operated (+CA) males and normal males.
