Abstract : Larvae of Anastrepha suspensa were submerged in heated water to determine effects on subsequent adult survival and reproduction. No relationship was observed between overall percentage larval mortality and proportion of larvae that survived hot-water immersion in grapefruits, mangoes and carambolas [Averrhoa carambola] and then developed into adults. Longevity of adults that survived immersion as larvae in water at 43.0±0.05°C for 21 or 24 min was not consistently lower compared with the unheated controls. Neither numbers of eggs laid nor percentage eclosion of eggs of adults that were immersed as 3rd-instar larvae in water at 43.0±0.05°C for 21 or 24 min differed significantly compared with controls. Eclosion of eggs from control females mated to males that survived immersion as 3rd-instar larvae in water at 43.0±0.05°C for 24 min was significantly reduced compared with eclosion of eggs laid by control females mated to control males.
