Abstract
The species Hedypathes betulinus species have larvae that form galleries that affect the vascular system Ilex Paraguaiensis, causing significant losses in the orchard. Adults remain on the branches and feed on the aerial parts of the plant and on pollen what can make the plant susceptible to microorganisms attack. After dissection and separation, histologic sections were obtained from ovaries fixed in mix of Bouin, dehydrated, embedded in paraffin and sections stained with HE. For ultrastructural analyzes the ovaries were fixed in Karnovsky solution, metalized with gold “sputtering” and glued on aluminum brackets. The goal was to understand the morphology of the female reproductive tract, H. betulinus and to describe the anatomy and the function of the reproductive system of this species, which causes significant losses in the orchard. The female reproductive system of H. betulinus consists of ovaries of the meroistic polytrophic type, with nurse cells located in the anterior region of the ovariole and the oocytes arranged according to their developmental stages. Structurally the ovaries are paired structures located dorsoventrally in relation to the intestine, each consisting of twelve ovarioles, comprising a filament end, germarium and vitellarium, coated by their own sheath and by the peritoneal sheath. The terminal filament, at the apex of ovarioles aids in support of the ovaries. The germarium made up of nurse cells, follicular cells and oogonia. Oocytes can be classified into I, II and III. The follicular epithelium shows up in stratified oocytes I, with simple elongated cells in oocytes II and with simple cubic cells into oocytes III. The calf is presented in the form of granules of size and varied density. The cup egg is formed by simple cubic epithelium.

Os aparelhos reprodutores foram acondicionados em cápsulas microporus (MICROPOR SPEC CAPSULE PK/50) e desidratados em banhos subsequentes, em série crescente de concentrações de etanol (70% a 100%) e acetona 100%, por 10 minutos
O material obtido foi: a) seccionado em micrótomo, com cinco a sete micrômetros de espessura; b) colocado em lâminas de vidro; c) corados em Hematoxilina/Eosina, passando em série alcoólica (100% a 70%) e xilol; d) montado com resina Entellan® e lamínula para posterior observação e documentação fotográfica

Cada ovário é constituído por doze ovaríolos, que se dispõem em duas fileiras: uma interna e outra externa, ao redor do ápice do cálice de ovos (Figura 2A e B).
