Diet source-dependent functional response of key parasitoids of <i>Spodoptera frugiperda</i> (J.E. Smith, 1797) (Lepidoptera, Noctuidae)

Foods derived from plants are important sources of food for natural enemies and influence several functions their existence, including reproduction. The objective the current study was to assess effect different host densities on oviposition efficiency key parasitoids Spodoptera frugiperda. experiment set up under laboratory conditions in a completely randomized block design with three factors namely (four), feeding (groundnut pollen, soybean nectar, honey, starved as control) (five), total 80 treatments. There were five replications experimental while repeated four times, 20 each treatment. Results showed that functional response adult influenced both by densities. Soybean nectar worked best like followed groundnut pollen. Soybeans may therefore have agroecological interests beneficial mass rearing promote biological agents control S. As densities, minimum maximum parasitized obtained respectively 100 eggs per female T. remus, Trichogramma sp. C. insularis 5 50 larvae marginiventris. Taking into account interesting results which would be favourable rapid multiplication parasitoids, tests real environments necessary test main environmental performance said parasitoids.
