The studies on metabolic enzymes、synergists and neurobioassays suggest that the monooxygenases、esterase and decreased nerve sensitity are involved in resistance to pyrethroids in the resistant HJ-R strain . The resistance to both organophosphorus and carbamate insecticides is mainly caused by metabolic mechanisms. The significantly synergistic effects of Pbo infer that the resistance to carbamata may be principally attributable to monooxygenases detoxification.

代谢酶系、增效作用以及神经电生理研究表明，HJ-R种群对拟除虫菊酯类杀虫剂的抗性是由多功能氧化酶及酯酶代谢增强、神经敏感性降低几个因子综合作用的结果；对有机磷、氨基甲酸酯类杀虫剂的抗性主要是由代谢机制引起，与靶标部位敏感性降低机制抗性无关，Pbo对HJ-R种群突出的增效作用，表明多功能氧化酶代谢在对灭多威的抗性中可能起主导作用。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.
