An approach was established to analyze the chemical profiling of Xiao-Cheng-Qi Decoction (XCQD) using liquid chromatography coupled with electrospray ionization tandem mass spectrometry. XCQD consisted of three herbal medicines (Rhubarb, Fructus Aurantii Immaturus and Cortex Magnoliae Officinalis). The traditional water extractive method was applied in the sample preparation, which was identica...

Aphidius transcaspicus Telenga, a mealy plum aphid (Hyalopterus pruni Geoffroy) parasitoid from the Mediterranean, was recently introduced into Hawaii for control of invasive aphids. Under laboratory conditions the parasitoid successfully attacked several important aphid pests in Hawaii, including the melon aphid Aphis gossypii Glover, the banana aphid Pentalonia nigronervosa (Coquerel), the gr...

Virulence of commercial strains entomopathogenic nematode (EPN) Steinernema carpocapsae (Weiser), feltiae Filipjev and Heterorhabditis bacteriophora Poinar (Rhabditida: Steinernematidae, Heterorhabditidae), were tested on young females Pulvinaria hydrangeae Steinweden, Partenolecanium corni (Bouché) Coccus pseudomagnoliarum (Kuwana) (Hemiptera, Coccidae) a native strain H. was citricola scale, ...

BACKGROUND Da Chengqi Tang (DCT) is a common purgative formula in Chinese medicine. Flavanones are its major active compounds derived from Fructus Aurantii Immaturus. The present study developed an LC-MS/MS method to characterize two pairs of flavanone 7-glycoside isomers, i.e., hesperidin versus neohesperidin and naringin versus isonaringin. METHODS After solid phase purification, components...

We present results of the inventory spider mites Massane Forest Nature Reserve made during several field samplings from 2013 to 2017. Nineteen species have been recorded, which represents more than one third known mite fauna in France. Among them, three new were disclosed and are described: Bryobia (Bryobia) alberensis sp. nov. collected on Phyteuma spicatum Helichrysum stoechas, B. (Periplanob...
