Objective To explore the possible defensive immunity of Culex pipiens quinquefasciatus larvae after being infected by Lagenidium giganteum .

Esterase activations of Culex pipiens quinquefasciatus treated by five essential oils;

Fumigating insecticidal activity of 5 essential oils against Culex pipiens quinquefasciatus;

Resistant Level,Frequency of Non-specific Esterases and Genetic Differentiation in Mosquitoes Culex pipiens quinquefasciatus in Three Cities of Guangdong;

Changes of Elements in Culex quinquefasciatus Larvae after Infected by Lagenidium giganteum (Oomycetes:lagenidiales);

Quantitative differences between populations of Culex quinquefasciatus in both the esterases α and β involved in insecticide resistance;

Delayed effects of mosquito-larvicidal Bacillus sphaericus on Culex quinquefasciatus;

Resistance Investigation of Culex pipiens pallens/quinquefasciatus to Five Pesticides and Control Strategy in Zhejiang Province;

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.
