Title: Investigation on the mosquito population density and seasonal fluctuation in Dongying city
Abstract: Objective To provide scientific basis for further prevention and control work of mosquito through the study on seasonal growth and decline trend of the mosquito species and density in Dongying city. Methods Monitoring the mosquito larvae density by spoon recapture method,and monitoring the adult mosquito density by mosquitoCO2-induced-lamp method. Identificating the morphology of the collection of adult mosquitoes and larvae,and recording the ambient tempreture,rainfall and humidity. Results The mosquito larvae density was raising from the firstlevel-area to the third-level-area. There was no significant diffrence( P 0. 05)) in the result by statistical adjustment.The mosquito larvae apeared in May and raised untile to August,disappeared in November. The dominant species populations were Culex pipiens pallens. The adult mosquito density in hospital was obviously higher than the other three kinds of monitoring spots. The adult mosquito density reached the highest point in August in park,squarean hospital but remains stable in the resident area from June to September. The data by statistical-treat-software SPSS13. 0 showed the impact on the seasonal growth and decline trend of the mosquito population with rainfall,tempreture and ambient facors( foods,competitor eg.). Conclusion The monitoring of mosquito species populations density should be enhanced whlie the large area of mosquito control measures is taken. The mosquito eradication and prevention work shoud be taken pertinently in hospital and resident area.
