Abstract
Hyperphagia resulted in all females of Culiseta inornata that were fed 1 M sucrose after the ventral nerve cord was severely damaged or severed in either abdominal segment I, II, or III. Hyperphagia also occurred in 42% of females fed successive higher concentrations of sucrose ranging from 0.25–2.0 M. The conclusions are: (1) Signals from receptors in the anterior abdominal segments limit the intake of sugary liquids; (2) this type of receptor is absent from the ventral diverticulum; and (3) excitatory input from oral receptors may dominate inhibitory input from abdominal stretch receptors.
