Objective To further vertify the bioactivities and mechanism of piperine and to investigate the effect of piperine on the ion channel of insect cytes, the toxicity and lethal effect of piperine against Culex pipiens pallens larvae and Spodoptera frugiperda cell line were investigated under the laboratory conditions.

Efficacy of insecticides mixture against Culex pipens pallens;

Study on the Biotic Fitness of Three Different Genotypes of Deltamethrin-Resistant Culex pipens pallens;

[Objective] To investigate the resistance of vector for Japanese Encephalitis(Culex tritaeniorhynchus and Culex pipens pallens) to three insecticides in Shanghai.

A Preliminary Investigation on the Control of Culex pipiens pallens with the Ethanol Extracts of Five Umbelliferae Herbal Medicines;

Bioactivity of Sarisan against Musca domestica L. and Culex pipiens pallens;

Resistance and analysis of Culex pipiens pallens to insecticides;

An investigation of the resistance of Culex pipiens pollens to insecticides and study on the control measures in Shandong Province.;

Culex pipiens pollens is a principal vector mosquito in northern China.

Objective:To understand the resistance status and study the control method of Cx.

The resistant levels of the second, third, fourth instar larvae, and early, middle, later stage adults of deltamethrin resistant and susceptible Cx.

Temperature effect of esterase mensuration in detecting the DDVP-resistance of Cx.Pipiens pallens;

Result: Filter paper test was used in this study to test the non-specific esterase(NSE) and acetylchotin(AchE) activities of susceptible and resistant strain of Cx.

Aim To provide insight into biochemical detection of insecticide resistance of mosquitoes and rational use of chemical insecticides,studying the fluctuation of non-specific esterase in different development stages of DDVP-resistant and susceptible Cx.
