Time/Mortality Relationships for Anastrepha suspensa (Diptera: Tephritidae) Eggs and Larvae Submerged in Hot Water
Time/mortality 'relationships were determined for eggs and 1- to 2-d-old and mature third-instar Caribbean fruit fly, Anastrepha suspensa (Loew), exposed to hot water. When eggs were submerged in water at 43.3, 46.1, 48.9, 51.7, or 54.4°C, estimated submersion times for 99% mortality were 24.8, 8.3, 2.0, 1.2, and 0.9 min, respectively; when larvae 1–2 d old were submerged in water at 43.3, 46.1, 48.9, 51.7, or 54.4°C, estimated submersion times for 99% mortality were 30.7, 6.6, 2.4, 1.5, and 0.7 min, respectively. When mature third instars were submerged in water at 40.56, 41.94, 43.3, 46.1, 48.9, 51.7, or 54.4°C, projected submersion times for 99% mortality were 77.8, 43.7, 13.5, 5.3, 2.0, 1.3, and 1.6 min, respectively. At 43.3 and 46.1°C, eggs were more resistant to heat than mature larvae and at 43.3°C, 1- to 2-d-old larvae were more resistant than mature larvae. The data may be useful in determining suitability of hot-water submersion treatments for disinfesting commodities attacked by A. suspensa and for comparing hot-water tolerance of A. suspensa with that of other tephritid species.
