A comparative study of the ovaries in some Brazilian bees (Hymenoptera; Apoidea) Pap. Avulsos de Zool. (São Paulo)
Martins,Gustavo Ferreira; Serrão,José Eduardo.
The present paper concerns the morphological features of ovaries in 33 species of bees with different social behavior patterns. The ovaries of bees were examined under light microscope. They are polytrophic-meroistic ovaries formed for an anterior germarium and a basal vitellarium. The germarium houses the germ cells and in the vitellarium there are follicles arranged linearly. In general the follicle is constituted by a nutritive chamber (a cluster of nurse cells) and an oocyte chamber, both covered by a single epithelial layer of follicular cells. The number of ovarioles per ovary and the number of mature oocyte per ovary were analyzed. Measurements of ovariole length, oocyte size, oocyte width, follicular epithelial height and the intertegular distance...

No direct effects of resistant soybean cultiva IAC-24 on Podisus nigrispinus (Heteroptera: Pentatomidae) Chilean J. Agric. Res.
Cola Zanuncio,José; Azevedo de Freitas,Fernando; de Souza Tavares,Wagner; Lourenção,André Luiz; Vinha Zanuncio,Teresinha; Serrão,José Eduardo.
The parameters of survival, development and reproduction of Podisus nigrispinus Dallas, 1851 (Heteroptera: Pentatomidae) may be affected by feeding on soybean (Glycine max L. Merr.; Fabaceae) cultivars. The direct effect was evaluated of the insect-resistant soybean 'IAC-24' (insect-susceptible soybean 'UFVS-2006' + pupae of Tenebrio molitor L., 1758 Coleoptera: Tenebrionidae versus 'IAC-24' plants + pupae of T. molitor) in the nymph and adult stages of the predator P. nigrispinus. The duration of the nymph stage was similar between treatments, but 'IAC-24' reduced the duration of the IV instar of this predator. The survival of P. nigrispinus was similar between treatments in the instars I, II, IV and V and in the nymph stage, but the survival of the III...
