dc.description.abstractThe effects of temperature on age-specific fecundity and life table parameters of the egg parasitoid Trissolcus semistriatus (Nees, 1834) (Hymenoptera: Scelionidae) were examined under four constant temperature conditions (17, 20, 26 and 32 degrees C), using eggs of the sunn pest Eurygaster integriceps Puton, 1881 (Hemiptera: Scutelleridae), an important pest of wheat, as hosts. The intrinsic rate of increase increased linearly, while the mean generation time and the doubling time decreased with increases in temperature. The net reproductive rate, however, varied without clear correlation with temperature. Fecundity tended to be higher at higher temperatures. The total number of eggs per female was estimated as 52.0 and 116.4 eggs, respectively, at 17 degrees C and 32 degrees C, with the highest fecundity rate during the first day of oviposition. The oviposition rate fluctuated from 4.4 to 14.3 eggs per day. Oviposition and postoviposition periods and longevity decreased when temperature increased. Maximum longevity for females was 21.6 days at 20 degrees C, and female parasitoids lived longer than males at all temperatures. The development period ranged from 7.1 days (32 degrees C) to 35.6 days (17 degrees C) for males and from 8.4 days (32 degrees C) to 37.2 days (17 degrees C) for females. The development of female T semistriatus required 166.7 degree-days (DD) above a theoretical threshold of 11.8 degrees C and the development of males required 142.9 DD above 13.1 degrees C. The numbers of generations per year for female and male T semistriatus, given the temperature in Tekirdag, Turkey, were estimated to be 9.0 and 8.8, respectively. The potential of the egg parasitoid for the control of E. integriceps is discussed.en_US
