Ovary histology of the predator Brontocoris tabidus (Hemiptera:Pentatomidae) of two ages fed on different diets
Entomological News 121 (3), 230-235
Abstract: The effect of different diets [Tenebrio molitor L. (Coleoptera: Tenebrionidae) pupae without plant; T. molitor pupae and Eucalyptus cloeziana plant; T. molitor pupae and Eucalyptus urophylla plant; T. molitor pupae and guava plant (Psidium guajava)] on the ovary histology of 15 and 21 day old female Brontocoris tabidus (Signoret, 1863) (Hemiptera: Pentatomidae) was analyzed. Females of B. tabidus have ovaries of the meroistic telotrophic type. The vitellarium of this predator presents oocytes with a linear arrangement in different development stages. The follicle cells are cubic with spherical nucleus when the oocytes are placed near the germarium in the initial developmental stage. These cells become flatter and compacted with the development of the oocytes. The ovaries of B. tabidus present similar histological features in all diets and ages. However, females of this predator reared on plants present more oocytes in advanced developmental stages inside the ovarioles than females of same age fed only on prey.
