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.

Variáveis hematológicas em tambaquis anestesiados com óleo de cravo e benzocaína
Provedor de dados: 86
Autores: Pádua,Santiago Benites de; Dias Neto,José; Sakabe,Róberson; Claudiano,Gustavo da Silva; Chagas,Edsandra Campos; Pilarski,Fabiana.
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.

Efeito alelopático do extrato alcoólico do cravo-da-índia e eugenol
Provedor de dados: 88
Autores: Mazzafera,Paulo.
Eugenol é um composto fenólico volátil e é o principal consituinte do óleo extraído do cravo-da-índia. Neste estudo verificou-se que extrato etanólico do cravo-da-índia e eugenol puro possuem efeito alelopático, inibindo a germinação de sementes de várias plantas, assim como diminuindo o crescimento de algumas delas quando aspergidas com o extrato. Não se verificou efeito alelopático de eugenol a longa distância, em função de sua característica volátil.

Development and evaluation of an inhalation chamber for in vivo tests
Provedor de dados: 42
Autores: SILVA,EDUARDO R. DA; BIZZO,HUMBERTO R.; FERNANDES,PATRÍCIA D.; VEIGA JUNIOR,VALDIR F. DA; LEITÃO,SUZANA G.; OLIVEIRA,DANILO R. DE.
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...

Evaluation of antifungal activity in essential oil of the Syzygium aromaticum (L.) by extraction, purification and analysis of its main component eugenol
Provedor de dados: 58
Autores: Rana,Inder Singh; Rana,Aarti Singh; Rajak,Ram Charan.
Antifungal properties of some essential oils have been well documented. Clove oil is reported to have strong antifungal activity against many fungal species. In this study we have evaluated antifungal potential of essential oil of Syzygium aromaticum (L.) against some common fungal pathogens of plants and animals namely, Fusarium moniliforme NCIM 1100, Fusarium oxysporum MTCC 284, Aspergillus sp., Mucor sp., Trichophyton rubrum and Microsporum gypseum. All fungal species were found to be inhibited by the oil when tested through agar well diffusion method. Minimum inhibitory concentration (MIC) was determined for all the species. Column chromatography was performed to separate the eugenol rich fraction from clove oil. Out of seven fractions maximum activity...

Phytochemical characterization and bioactivity of ethanolic extracts on eggs of citrus blackfly
Provedor de dados: 65
Autores: Lima,Bruno Marcus Freire Vieira; Oliveira,Rosilene Aparecida de; Santos,Emerson Alves dos; Bittencourt,Maria Aparecida Leão; Santos,Olivia Oliveira dos.
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. &amp; 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...
