ABSTRACT. Effects of temperature on the development, fecundity, and longevity of Gargaphia torresi Lima (Hemiptera, Tingidae). The development of Gargaphia torresi Lima on cotton leaves was studied in bioclimatic chambers at 20, 23, 25, 28 The values of longevity and fecundity were inversely proportional with increase of the temperature. The thermal constant (K) and theoretical lower threshold temperature of development (Tb) were estimated by Reamur law and intercession method of the X, respectively. The theoretical lower threshold temperature of development for individuals that originated adult females and males were 13.9 o C and 13.6 o C, respectively. The immature stages for individuals that originated adult females and males required 209.4 and 220.3 degrees-days from oviposition to adult emergence, respectively.

Os valores de longevidade e fecundidade foram inversamente proporcionais ao aumento da temperatura. As exigências térmicas (K) e temperaturas-base (Tb) foram estimadas para cada um dos estágios imaturos e de ovo à emergência de adultos (machos e fêmeas) de acordo com a Lei de Reamur e com o método de intercecção de X, respectivamente. Os estágios imaturos para indivíduos que originaram fêmeas e machos adultos requereram 209,4 e 220,3 graus-dia da oviposição à emergência do adulto, respectivamente, acima dos limites inferiores de 13,9 e 13,6ºC.
RESUMO. O desenvolvimento de Gargaphia torresi
