. Regular flight exercise of adult male Locusta migratoria migratorioides (R and F) accelerated the development of maximum flight speed and disrupted the development of the typical pattern of change of flight speed exhibited when normal (untrained) adult male laboratory locusts are flown on roundabouts. Thus, while untrained mature locusts fly fast initially and then slow to a steady cruising speed after 20 min, trained locusts flew at a relatively constant speed throughout a 60‐min test period. Flight training also led to a marked reduction in the size of the fat body and the flight muscles, but flight muscle ultrastructural development was not affected. Regular flight exercise had no long‐term effect on haemolymph carbohydrate concentration but lipid levels were significantly depressed.
