MICHEL, Adriana A.  y  TERAN, Héctor R.. Morphological analysis of the female reproductive system in Baeacris punctulatus (Orthoptera, Acrididae, Melanoplinae). Rev. Soc. Entomol. Argent. [online]. 2005, vol.64, n.3, pp.107-117. ISSN 0373-5680.

ABSTRACT. Baeacris punctulatus (Thunberg) is an economical important species widely distributed in Southamerica. In the present contribution an anatomical-histological study of the internal reproductive organs from females collected in the wild and also laboratory raid was carried out. The present study allowed us to determine histomorphologic particularities in the ovaries, accessory glands, lateral oviducts and medial oviduct related with gamete genesis and transference and oviposition. The spermathecal organ is characterized by its external morphology and histology of its regions and compare to closely related species. The type of spermatheca observed in Baeacris punctulatus is not included in the current classification of Orthoptera. The morphology of the genital chamber and regions used in breeding, oviposition and fecundation of oocytes are described and characterized by its histology. New data to contribute to the understanding of reproductive biology and systematic position of the Acrididae is provided.
