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. |

O objetivo deste trabalho foi avaliar o efeito anestésico de óleo de cravo e benzocaína sobre os parâmetros hematológicas e a fragilidade osmótica dos eritrócitos em tambaqui (Colossoma macropomum). Trinta peixes adultos foram avaliados em três tratamentos: controle, sem anestesia; anestesia com óleo de cravo a 50 mg L-1; e anestesia com benzocaína a 100 mg L-1. O sangue dos peixes foi coletado para a determinação do hemograma, e o teste de fragilidade osmótica dos eritrócitos foi aplicado. As doses utilizadas de óleo de cravo e benzocaína não são adequadas para estudos hematológicos, para estabelecer valores de referência em tambaquis, pois causam alterações expressivas dos parâmetros hematológicos, tais como leucocitose e hemólise iatrogênica. |

ABSTRACT The bioavailability, toxicity, and therapeutic efficacy of a drug is directly related to its administration route. The pulmonary route can be accessed by inhalation after fumigation, vaporization or nebulization. Thus, pharmacological and toxicological evaluation accessed by an apparatus specifically designed and validated for this type of administration is extremely important. Based on pre-existing models, an inhalation chamber was developed. This presents a central structure with five animal holders. The nebulized air passes directly and continuously through these holders and subsequently to an outlet. Evaluation of its operation was performed using clove essential oil, a nebulizer, and a flow meter. The air within the chamber was collected by... |

ABSTRACT: The main objectives of this study were to determine the content of secondary metabolites (carotenoids, flavonoids, phenolic compounds, and tannins) of Argemone mexicana L., Ipomoea carnea Jacq. subsp. Fistulosa (Martius ex Choisy), Amorimia rigida (A.Juss.) W. R. Anderson, Ricinus communis L. and Syzygium aromaticum (L.) Merr. & L. M. Perry using UV-VIS spectroscopy, and evaluating the bioactivity of the ethanolic extracts on citrus blackfly eggs (Aleurocanthus woglumi Ashby, 1915). Pera sweet orange leaves infested with citrus blackfly eggs were treated by immersion in 0.5, 1.0, 5.0, and 10%; each replicate consisted of 30 eggs. The experimental design was completely randomized, with seven treatments and four replications. Three immersions... |
