摘要：

Adult C. terminifera deprived of water for 24 h took larger meals of water than insects deprived for 2 h. Water or dilute solutions of NaCl injected into the hemocoel reduced the amount of water ingested by 24 h deprived locusts. Injections of more concentrated solutions of NaCl (0.5 M) or glycerol (1.0 M) increased the water intake of 2 h deprived locusts. Water injections into 24 h deprived locusts did not reduce their responsiveness to sucrose; hemolymph osmotic pressure probably plays an important role in determining the specific responsiveness of C. terminifera to water. The time course of the effects of injection indicates that the effects of hemolymph osmotic pressure on water responsiveness are mediated neurally. Injections of water in 24 h deprived insects caused a marked reduction in the sizes of their meals of seedling wheat. The mechanisms responsible for regulation of water intake might limit total intake when locusts have access only to fresh vegetation of high water content.
