“…Release of these predators against insect pests makes it necessary to study their biology and mass rearing so as to produce the highest possible number of individuals (Zanuncio et al, 2001). For this reason, these natural enemies have been reared with alternative preys such as Tenebrio molitor L., 1758 (Coleoptera: Tenebrionidae), Musca domestica L., 1758 (Diptera: Muscidae), or Bombyx mori L., 1758 (Lepidoptera: Bombycidae) (Beserra et al, 1995;Zanuncio et al, 1996Zanuncio et al, /1997Molina-Rugama et al, 1997;Nascimento et al, 1997;Jusselino Filho et al, 2001), in addition to artificial diets (Zanuncio et al, 1996;Saavedra et al, 1997;Coracini et al, 1999;De Clercq et al, 1998;and Rojas et al, 2000).…”
