Genetic variation in the effect of monoamines on female mating receptivity and oviposition in the adzuki bean beetle, Callosobruchus chinensis (Coleoptera: Bruchidae).

ABSTRACT:

Background

Female mate choice after mating is a strong force in sexual selection and could lead to coevolution of mating traits between the sexes. How females of different genotypes respond to substances in the male ejaculate should be mediated by females' mate choices. Monoamines regulate animal physiology and behavior, including the post-mating behavior of females of the adzuki bean beetle, Callosobruchus chinensis (Coleoptera: Bruchidae). This study examined differences in females' response to four monoamines (dopamine, octopamine, tyramine, serotonin) between strains from different populations of C. chinensis.

Results

Injection with either octopamine or tyramine, two kinds of monoamines significantly reduced female receptivity in two strains with low remating frequencies
