In this study, we investigated the impact of different food sources on life-history traits, such as longevity and fecundity, in females egg parasitoids of six Trichogramma species (two thelytokous and four arrhenotokous): T. cacoeciae Marchal, T. chilonis Ishii, T. minutum Riley, T. leptoparameron Dyurich, T. pintoi Voegele and T. sibericum Sorokina (Hymenoptera: Trichogrammatidae). Five treatments were tested: control (no food, no host), sugar (provided as honey), sugar and hosts, hosts. Hosts were provided as eggs of Ephestia kuehniella. Females were either dissected and oocytes were count at emergence, at death or at different time during their life.
