Table 6 Body composition of three species of Ceratitis prior to and after a 24-h period of starvation at 25 °C and 0 % or 100 % relative humidity

From: Physiological mechanisms of dehydration tolerance contribute to the invasion potential of Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) relative to its less widely distributed congeners
