説明

<jats:title>Abstract</jats:title> <jats:p> A queen honey bee mates at ∼6 days of age, storing the sperm in her spermatheca for life. Mating is associated with profound changes in the behaviour and physiology of the queen but the mechanisms underlying these changes are poorly understood. What is known is that the presence of semen in the oviducts and spermatheca is insufficient to initiate laying, and that copulation or <jats:styled-content style="fixed-case"> <jats:roman>CO</jats:roman> <jats:sub>2</jats:sub> </jats:styled-content> narcosis is necessary for ovary activation. In this study we use real‐time quantitative <jats:styled-content style="fixed-case">PCR</jats:styled-content> to investigate the expression of biogenic amine receptor genes in the brain and ovarian tissue of queens in relation to their reproductive status. We show that dopamine, octopamine and serotonin receptor genes are expressed in the ovaries of queens, and that natural mating, <jats:styled-content style="fixed-case"> <jats:roman>CO</jats:roman> <jats:sub>2</jats:sub> </jats:styled-content> narcosis, and the presence of semen in the spermatheca differentially affect their expression. We suggest that these changes may be central to the hormonal cascades that are necessary to initiate oogenesis. </jats:p>
