Abstract:
In laboratory populations of Earias insulana Boisduval (Lepidoptera: Noctuidae) crowding did not affect spermatophore production by males or its acceptance by females. Sex ratio affected spermatophore transfer. A low male: female ratio resulted in the transfer of a large number of spermatophores per male. On the other hand, a high male: female ratio resulted in a high mating frequency of females. Egg production and hatching were not affected. © 1983, Springer Science + Business Media B.V..
