This study has been carried out to determine some biological parameters of Trissolcus semistriatus Nees (Hymenoptera: Scelionidae) on alternative host, Graphosoma lineatum (L.) (Heteroptera: Pentatomidae) eggs at constant (25±1 ºC) and variable temperatures (25-20±1 and 28-23±1 ºC), 60±10% relative humidity, 14:10 photoperiod conditions in the laboratory. The highest fecundity was 175.40±8.73 days at 28-23±1 ºC. It was recorded that the longest longevity of female and male were 33.0±0.96 and 16.33±1.41 days, respectively and oviposition period was 22.25±1.33 days at 28-23±1 ºC. However, the best results of emergence and sexual ratio were obtained at 25-20±1 ºC. As a result, it was concluded that the temperature of 28-23±1 ºC was more suitable for the mass production of T. semistriatus. |
