Abstract:

　　【Abstract】　Objective　To compare the developmental duration and vector capacity of malaria transmission of Anopheles anthropophagus from Liaoning and Jiangsu on pre-mature stage. Methods　In laboratory, An.anthropophagus from Liaoning and Jiangsu were reared in the same environment and infected artificially in vitro. The biological indexes such as hatchability, emergence rate, pupation rate, the positive rate of mosquito stomach and oocyst and sporozoite infection rate of salivary gland were observed, respectively. Results   The average developmental duration of egg from Liaoning population and Jiangsu population were 3.66 d and 3.84 d, and the hatchibility of egg were 76.0% and 74.3%. That of larva were 6.67 d and 8.26 d and the pupation rates were 94.7% and 96.0%. That of pupa were 1.60 d and 1.72 d and the emergence rates were 97.2% and 98.6%. The positive rates of mosquito stomach and oocyst were 25.1% and 28.1%, and the sporozoite infection rates of mosquito salivary gland were 8.4% and 10.7%. Conclusion　It was no significant difference statistically between the developmental duration of larva and vector capability of malaria transmission of An.anthropophagus from Liaoning and Jiangsu （P＞0.05）. Therefore, the surveillance of vector should be strengthened during malaria transmission period.
