The Chinese army worm Pseudaletia separata (Walker is a widely distributed seriouspest of field crops in China.

粘虫Ps洲而let汤，eP，、J是粮食作物的毁灭性害虫，也是全国农业发展栖要所规定要消灭的八大害虫之一。

Since genomic DNA of high quality is a crucial prerequisite for molecular ecology studies, we specially detected efficient protocols to isolate high-quality genomic DNA from ethanol-preserved Pseudaletia separata adults of several natural populations trapped by light traps in fields of different areas.

高质量的基因组DNA样品是分子生态学研究的先决条件。

The results from bioassay showed that both the capsules of PuGV－Ps and the partially purified synergistic factor enhanced infection of Pseudaletia separata nuclear polyhedrosis virus in the larvae of armyworm significantly.

生物测定的结果表明，粘虫颗粒体病毒PuGV－Ps及其增效因子对粘虫核型多角体病毒PsNPV均有明显的增效作用。
