Objective To investigate mosquito species and breeding sources of mosquito larvae in rice paddies in southwest area of Shandong province and provide the basis for mosquito control in rice culturing area. Methods Mosquito larvae were collected from the habitats with dipping technique, Meanwhile adult mosquitoes were trapped by human-bait net, CO2 trapping lamp method and net capture method from wild habitats. Results In total, 11 species belonging to 6 genera were collected, among which 9 species were indicated by larvae, 11 species by adults. The predominant species were Culex tritaeniorhynchus Giles, Cx. pipiens pallens Coquillet and Anopheles sinensis Wiedemann, with ratios of 45.79%, 29.32% and 22.74%, respectively. The density of Culex and Anopheles larvae in rice paddies peaked in mid-to-late July and August. During epidemic season, the minimum and maximum density of Culex larvae were 0.08 and 1.88 larvae/dip, respectively. Meanwhile, the minimum and maximum density of Anopheles larvae were 0.09 and 2.82 larvae/dip, respectively. However, mosquito larvae were collected from rice paddies during all growing period of rice. Conclusion There is a rich biodiversity of mosquito species and breeding sources of mosquito larvae in rice culturing land in southwest area of Shandong province. Intermittent irrigation to control larvae in the rice fields may have been widely adopted, and above all, controlling adult mosquitoes is the best method to reduce mosquito-borne infectious diseases in this area.
