Abstract(s)

The relationships between Apanteles militaris and the number of host's larvae of Mythimna unipuncta (Haworth) (Lep., Noctuidae) that can be parasitized, was the subject of this study. One parasitoid female parasitizes one, two, four, six or ten larvae of M. unipuncta during 24 hours. There was a relationship between the total number of larvae and the number of parasitized hosts. A significant difference was found among the progeny. The number of hosts per parasitoid did not significantly affect the sex ratio and the progeny adult emergence.
