Description
| - U několika druhů hmyzu může dojít k reprodukční izolací asynchronizací denních rytmů v sexuální aktivitě. Porovnali jsme denní rytmy v uvolňování feromonů u dvou druhů zavíječů: Ephestia kuehniella and Plodia interpunctella (Lepidoptera: Pyralidae), které obsahují stejnou hlavní složku ve feromonech. Imunocytochemická studie neropepridu PBAN, corazoninu a PDH v mozcích obou druhů ukázala, že jejich distribuce je lehce odlišná, což ukazuje na rozdíly v expresi i lokalizaci těchto složek ve výstupní dráze cirkadiáních hodin.

- Sex pheromone communication generally occurs at restricted hours of the day, usually at dawn or dusk, and the daily rhythm in sex pheromone biosynthesis in the turnip moth, Agrotis segetum, is regulated by a circadian clock mechanism. We here show data supporting a circadian rhythm in PBAN release from the corpora cardiaca, which we propose regulates the endogenous rhythm in sex pheromone biosynthesis. This conclusion is drawn as the observed daily rhythm in PBAN-like immunoreactivity in the hemolymph is persistent in constant darkness and is phaseshifted by an advanced light:dark cycle.
