Résumé :
|
Prior to migratory flight of alatiform aphids, their total volume of mycetocyte was greatly reduced. Since in this period they ingest little food, it is likely that they develop the flight muscles at the cost of their mycetocytes. In this period, not only the size and number of the mycetocyte but also the density of endosymbionts in the cell decreased. Starving aphids resulted in a sharp decrease in the total volume of mycetocyte, which was reversed by refeeding, suggesting that aphids consume their mycetocytes harboring endosymbionts as a nutrient source on their physiological demands.
