Abstract Age-related consumption and longevity were monitored in the laboratory for adultA. ipsilon fed either a 1M sucrose solution or water. An additional group was completely starved. Adults consumed sucrose solution and water just after eclosion; the percentage feeding daily and the mean daily consumption for females and males fed sucrose solution declined with time, whereas the percentage feeding daily and the mean daily consumption of those fed water increased with time. Total consumption was significantly higher for those fed sucrose solution (P〈0.01) because they lived longer, but consumption per day averaged over the entire adult stage was not significantly different between those fed sucrose solution and those fed water (P〉0.05). Mean longevity was significantly extended for females and males fed sucrose solution over those fed water or starved (P〈0.01). Moreover, consumption of either fluid was significantly correlated with extended longevity in all groups (P〈0.05). These data on fluid consumption by adultA. ipsilon are discussed relative to posteclosion migratory activities.
