Popis: The lipid composition of flight muscle mitochondria was determined in adult male Schistocerca gregaria acclimated for 30 days at 31°C and 45°C respectively. Locusts held at 31°C showed lower levels of phosphatidylcholine and higher levels of phosphatidylethanolamine than the 45°C-acclimated insects. A trend towards an increased cholesterol:phospholipid ratio was also observed at the higher temperature. Wide angle X-ray diffraction procedures indicated a difference of 5°C in the lipid phase transition temperatures of mitochondrial preparations derived from the two groups of insects with the 45°C-acclimated samples demonstrating the higher transition temperature.
