EFFECT OF SPATIO-TEMPORAL FACTORS ON MOSQ-OVITRAP TRAPPING EFFICACY FOR AEDES ALBOPICTUS SURVEILLANCE

LIN Li-Feng~ 1,2 CAI Song-Wu~2 LI Rong-Biao~3 LU Wen-Cheng~2 CHEN Qing~1 (1.Nanfang Medical University,Guangzhou 510515;2.Center for Disease Control and Prevention of Guangdong Province,Guangzhou 510300;3.Center for Disease Control and Prevention of Chancheng District,Foshan City,Foshan 528000)  
In order to establish a sensitive,effective,and feasible surveillance method for dengue fever vector,the effect of spatial and temporal factors on mosq-ovitrap trapping were analyzed for Aedes albopictus surveillance in the field.Mosq-ovitraps were set under the trees,flowers or brushwood in the field for 2,3,4 and 7days,for temporal analysis;and were set on the ground,1.0m and 1.5m height for 4 days for spatial analysis.The mosq-ovitrap oviposition indexes were 23.4,38.5,50.3 and 72.8 respectively when set for 2,3,4 and 7days,and were 19.30,9.26,and 4.63 when set on the ground,1.0m and 1.5m height for 4 days respectively.The longer time the traps were set,the more mosquitoes were captured,but the rate of alive mosquitoes decreased.It was the conclusion that the mosq-ovitrap for Aedes albopictus surveillance was most sensitive and effective when set on the ground under the trees,flowers or brushwood for 4 days.
