The legume pod borer, Maruca vitrata (Lepidoptera: Crambidae; syn. M. testulalis), is a serious pantropical insect pest of grain legumes. Comparative studies of M. vitrata female sex pheromone components in two different geographic populations in China, Wuhan and Huazhou, confirmed that (E,E)-10,12-hexadecadienal (E10,E12-16:Ald) and (E)-10-hexadecenal(More)
The longicorn beetle Xylotrechus grayii (White, 1855) has been spreading rapidly in China, causing mass mortality of honeysuckle which is economically and medicinally important. In order to elucidate the mechanisms of mate and host location and to advance efficient control methods, antennal sensilla features were investigated in both sexes of X. grayii(More)
To investigate the production status and the safety influence factors of wolfberry in China. We investigated the detailed factors which affect the quality safe of wolfberry in the periods of July-August 2013 and July-September 2009. The factors include fertilizing patterns, the used pesticide and preliminary process wolfberry. The factors were discussed(More)
OBJECTIVE To study the volatile compounds from inflorescence of Cistanche deserticola and provide basis for its utilization and seed breeding. METHODS The volatile compounds were collected by dynamic headspace adsorption and analyzed by gas chromatography-mass spectrometry (GC-MS). RESULTS Forty volatile components were identified in inflorescence of(More)
OBJECTIVE To find out whether and how the newly invented technique-bionic glue affects the main pest of wolf berry-Paratrioza sinica and its natural enemies Tamarixia lyciumi and Chrysopa septempunctata. METHOD Spraying bionic glue in field when wolf berry just geminated, investigated the adults and nymphs of P. sinica and it's natural enemies: adults of(More)
We sequenced the complete mitochondrial genome of the longhorn beetle, Xylotrechus grayii. The total length of the X. grayii mitogenome was 15,540 bp with an A + T content of 75.29%, consisting of 13 protein-coding genes (PCGs), 22 tRNA genes, 2 rRNA genes and an A + T-rich region. All the genes were arranged in the same order as that of the ancestral(More)
OBJECTIVE The aim of the present study was to screen the Metarhizium strains with high virulence against the larvae of Dorysthenes hydropicus, a serious pest of Citrus grandis. METHOD Thirty six strains of Metarhiziums were isolated from the soil of C. grandis GAP base and collected from other institutions, and the pathogenicity of these strains against(More)
