Parasitoids performance depends on their age, and on host quality. Performance decreases with age, and low-quality hosts will be parasitized only by old wasps. Age didn´t affect Telenomus podisi or Trissolcus urichi survival or parasitism, but produced a male biased offspring when parasitizing Piezodorus guildinii, a high-quality host. Young Trissolcus basalis didn´t parasitize; parasitism and preimaginal survival decreased with age, and sex ratio didn´t change with age. Parasitoid age affected wasps? performance, inducing T. basalis to attack a low-quality host.
