Reproduction and longevity of Supputius cincticeps (Het.: Pentatomidae) fed with larvae of Zophobas confusa, Tenebrio molitor (Col.: Tenebrionidae) or Musca domestica (Dip.: Muscidae) BABT
Zanuncio,José Cola; Beserra,Eduardo Barbosa; Molina-Rugama,Adrián José; Zanuncio,Teresinha Vinha; Pinon,Tobias Baruc Moreira; Maffia,Vanessa Pataro.
Reproduction and longevity of Supputius cincticeps (Stål) (Heteroptera: Pentatomidae) fed on Zophobas confusa Gebien, Tenebrio molitor L. (Coleoptera: Tenebrionidae) or Musca domestica (L.) (Diptera: Muscidae) larvae were studied during two generations at 24.7 ± 1.1ºC, 70 ± 10% R.H. and 12 h of photophase. Body weight of newly-emerged adults, oviposition period, number of egg masses, total number of eggs and longevity of S. cincticeps were higher when fed on Z. confusa or T. molitor larvae than on M. domestica larvae. Regardless of diet, S. cincticeps showed better reproduction and longevity in the second generation in laboratory conditions.

Impact of the number of Spodoptera frugiperda egg layers on parasitism by Trichogramma atopovirilia Scientia Agricola
Beserra,Eduardo Barbosa; Parra,José Roberto Postali.
Egg parasitoids of the genus Trichogramma (Hymenoptera: Trichogrammatidae) can be found in several crops attacking Spodoptera frugiperda (J. E. Smith, 1797) (Lepidoptera: Noctuidae) eggs. It is therefore necessary to demonstrate the capacity of these natural enemies in suppressing populations of the pest to allow them to be used in biological control programs against that species. This work had the objective of evaluating the impact of egg layer distribution in S. frugiperda egg masses on the parasitism capacity of Trichogramma atopovirilia Oatman & Platner, 1983. Masses containing one, two, and three layers were used as treatments, and 1.6 parasitoid per egg of the pest were released. Parasitism percentage differences were observed among the three...
