Nutritional characteristics of marine fish Bleeker and immunostimulatory activities of its glycoprotein.

Bleeker, an edible and medicinal marine fish, is largely distributed in tropical oceans. However, the chemical composition and nutritional properties of this species have not yet been investigated. In the present study, proximate composition, fatty acids, amino acids, taurine, and minerals of Bleeker were characterized, and the immunostimulatory properties of its glycoprotein were evaluated.

Biochemical mechanisms of imidacloprid resistance in Nilaparvata lugens: over-expression of cytochrome P450 CYP6AY1.

Imidacloprid is a key insecticide extensively used for control of Nilaparvata lugens, and its resistance had been reported both in the laboratory selected strains and field populations. A target site mutation Y151S in two nicotinic acetylcholine receptor subunits and enhanced oxidative detoxification have been identified in the laboratory resistant strain, contributing importantly to imidacloprid resistance in N. lugens.
