Abstract: In this study, the maximum and minimum lethal temperatures (LT50) of L. intermedia and L. laeta were determined in two treatments: gradual heating (25-50degreesC) and cooling (25degreesC to -5degreesC), and 1 h at a constant temperature. In gradual temperatures change, L. intermedia mortality started at 40degreesC and the LT50 was 42degreesC; for L. laeta, mortality began at 35degreesC and the LT50 was 40degreesC. At low temperatures, mortality was registered only at -5degreesC for both species. In the constant temperature L. intermedia showed a maximum LT50 at 35degreesC and L. laeta at 32degreesC; the minimum LT for both species was -7degreesC. (C) 2003 Elsevier Ltd. All rights reserved.
