Temperature and development rate of Triatoma guasayana (Hemiptera: Reduviidae) eggs under laboratory conditions: Physiological and adaptive aspects

Eggs laid in the laboratory by T. guasayana (Wygodzinsky & Abalos 1949) adults collected from wild biotopes in Santiago del Estero (Argentina) were exposed to fluctuating temperatures, and 172 egg batches, involving 1574 eggs, completed development. Their development times were fitted to the lin...

The lower development threshold is estimated to be 15°C (linear devar model) and 17.5°C (Lactin model), and the temperature resulting in the shortest development time is estimated to be between 26°C (Lactin model) and 37°C (nonlinear devar model). The thermal death point by the Lactin model is 34.4°C, and conforms well with other studies. Differences between the present results and those of other studies for T. guasayana are discussed in terms of the maternal effects, the influence of experimental conditions, and the rate summation effect. Using the climatic conditions of the natural environment of T. guasayana, the results are interpreted in terms of physiological adaptation. A generalized development rate response of T. guasayana eggs to increasing temperature is proposed, with three ranges: between 10 and 14.8°C development rate increases in an accelerating way; between 14.8 and 29.2°C development rate increases more or less linearly, and between 29.2 and 34°C development rate decreases. © 2006 The Royal Entomological Society.
