Throughout the history of citrus production in Florida one of the diseases with a major impact has been the Asian form of citrus greening (HLB), which was first detected in 2005. As a response to this introduction, new survey and detection methods had to be developed utilizing field observations directed not only to corroborate symptoms already reported in the literature, but to describe any va...

Introducción: en la actualidad el uso de productos naturales son una opción tratamiento diversas enfermedades, como bien podría ser oleorresina copaiba, que presenta propiedades podrían usadas un coadyuvante periodontitis. Objetivo: determinar efecto clínico y antibacteriano Copaifera reticulata (C. reticulata) «copaiba» apoyo a terapia periodontal no quirúrgica (TPNQ) periodontitis pacientes d...

Expression of the immediate-early gene c-fos has been advanced as a marker of neuronal activity in the adult nervous system. We sought to test the validity of c-fos mRNA expression as a marker of neuronal activity during seizures and to elucidate specific neurotransmitter receptors whose activation was necessary for seizure-evoked c-fos mRNA expression. We correlated c-fos mRNA expression, meas...

ABSTRACT Citriculture is a growing industry in Pará state, Brazil, but information regarding fruit flies and their associated parasitoids this region lacking. To address gap knowledge, we collected oranges (Citrus sinensis), lime (C. common sweet limes limettioides), citrons medica) mandarins reticulata). We recorded field infestation by Anastrepha obliqua C. sinensis under natural conditions f...

In this study peroxidase was isolated from peels of Citrus reticulata var. Kinnow and partially purified using ammonium sulphate precipitation method. Kinetic and thermal characterization of the partially purified enzyme was explored. The optimum pH and temperature were found to be 6 and 55 C respectively. The Km and Vmax values for guaiacol as substrate were found out to be 0.66 mM and 380 μmo...

ABSTRACT: Due to the importance of essential oils and their use in various industries, the essential oils of four types of citrus consisting of orange (C. sinesis), tangerine (C. reticulate), sweet lemon (C. limetta) and sour lemon (C. limon) were extracted and subjected to chemical analysis to identify and evaluate the chemical constituents of the oils. The average essential oils of orange, ta...

Host plant resistance to the Diaprepes root weevil, Diaprepes abbreviatus (L.) was assessed for seedlings of 54 Poncirus trifoliata (L.) Raf. selections and two families of progeny from crosses between Citrus and P. trifoliata. Weight gain was consistently lower when larvae were reared in pots containing the progeny of Citrus reticulata Blanco 'Sunki' x P. trifoliata 'Flying Dragon' compared wi...

Oil-resin fractions from Copaifera reticulata Ducke (Leguminosae-Caesalpinoideae) were evaluated for larvicidal activity on third larval instars of Aedes aegypti, in searching for alternative control methods for this mosquito. The bioactive fractions were chemically monitored by thinlayer chromatography, H and C nuclear magnetic resonance and mass spectrometry. Bioassays were performed using fi...
