The glucocorticoid dexamethasone has been largely used due to its anti-inflammatory effect. However, several authors report that the excessive exposition to it during pregnancy may cause a retard in the development in several tissues, mainly: liver, lungs and kidneys. But, the majority of the works are done with the application of dexamethasone in the late periods of pregnancy. Because of the lack of researches that evalúate the effects in the beginning of gestation, this paper aimed at evaluating the effect of dexamethasone administered in the initial phase of pregnancy, o ver the morphology of neonates rat. It was used 10 albino rats (Rattus norvegicus albinus) aged 90 days from the lineage Wistar. The female were coupled and divided in two groups: Group...

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.
