Effects of constant and alternating temperatures on Trichogramma galloi Zucchi (Hym., Trichogrammatidae) biology. I. Development and thermal requirements

Abstract: This work was carried out in order to study the effects of constant and alternating temperatures on the development and thermal requirements of Trichogramma galloi, the most common egg parasitoid of the sugarcane borer in Brazil. T. galloi developmental time was shorter when reared at alternating temperatures. The emergence rate of T. galloi decreased at constant 18°C, and the sexual ratio was affected only at 32°C. T. galloi degree-days and threshold temperatures were similar when estimated using constant or alternating temperatures.
