Histological and Histochemical Changes by Clove Essential Oil Upon the Gonads of Spodoptera frugiperda (JE Smith) (Lepidoptera: Noctuidae) International Journal of Morphology
Cruz,Glaucilane dos Santos; Teixeira,Valeria Wanderley; de Oliveira,Jose Vargas; Teixeira,Alvaro Aguiar Coelho; Araújo,Alicely Correia; Alves,Thiago Jose de Souza; da Cunha,Franklin Magliano; Breda,Mariana Oliveira.
Spodoptera frugiperda is a polyphagous insect that causes economic losses to several crops in Brazil and is the major obstacle to corn production. Researches focusing on alternative control, e.g. botanical products are expanding to offer a wide variety of molecules that interfere with different biological parameters of insect pests. Thus, this study tested the hypothesis that clove essential oil affects the spermatogenesis, ovarioles histochemistry and the fertility of S. frugiperda. The results showed that clove essential oil affects the gametogenesis of S. frugiperda ovarioles, reflecting negatively on its reproduction, proving to be a promising tool for controlling this pest.

MORPHOMETRIC ANALYSIS OF THE DEVELOPMENT OF THE OVARIAN FOLLICLES IN PINEALECTOMIZED RATS International Journal of Morphology
Pereira dos Santos,Katharine Raquel; Coelho Teixeira,Álvaro Aguiar; da Silva Neto,Eulâmpio José; Teixeira,Valéria Wanderley; da Cunha,Franklin Magliano.
The present study had the objective of analyzing morphometrically the occupied area by the ovarian follicles in ovaries of pinealectomized female rats. To do so, 24 albino female rats (Rattus norvegicus albinus) were used, which were equally divided in the following groups: Group I ­ sham-pinealectomized rats and kept in the light/dark cycle (12/12 hours), for three months; Group II ­ pinealectomized rats and kept in the light/dark cycle (12/12 hours), for three months; Group III ­ pinealectomized rats and kept in the absence of light for three months; Group IV ­ sham-pinealectomized rats and kept in the absence of rats for three months. The results showed that the groups I and IV presented, respectively, average of 19,00 and 25,00, while groups II and III...
