|Title:||Determination Of The Maximum And Minimum Lethal Temperatures (lt 50) For Loxosceles Intermedia Mello-leitão, 1934 And L. Laeta (nicolet, 1849) (araneae, Sicariidae)|
|Abstract:||In this study, the maximum and minimum lethal temperatures (LT 50) of L. intermedia and L. laeta were determined in two treatments: gradual heating (25-50°C) and cooling (25°C to -5°C), and 1 h at a constant temperature. In gradual temperatures change, L. intermedia mortality started at 40°C and the LT50 was 42°C; for L. laeta, mortality began at 35°C and the LT50 was 40°C. At low temperatures, mortality was registered only at -5°C for both species. In the constant temperature L. intermedia showed a maximum LT50 at 35°C and L. laeta at 32°C; the minimum LT for both species was -7°C. © 2003 Elsevier Ltd. All rights reserved.|
