Abstract: Purpose: To observe the fecundity and longevity of Anopheles sinensis under the condition of daily supply of blood meal. Methods:The mosquito's habits of blood taking and egg laying was observed and the mosquito's daily mortality was recorded, and the results were compared with unfed female mosquito control.Results:194 female mosquitoes laid a total of 28 377 eggs; the mosquito started to take blood meal after emergence at day 1.5 and such activity may last up to day 38;the mosquito began to lay egg at day 3 after having taken blood meal;the mosquito was still able to lay eggs at day 35 during the whole adulthood;the egg laying peak period was on day 5-16;the average longevity of male,fed female,unfed control female were 12.44±5.78,24.29±9.08 and 17.46±5.76(day),respectively.There is statistical significance in the mosquito's longevity difference for both sexes and between fed and unfed female control(P＜0.001）,the daily blood-fed mosquitoes lived longer than the unfed ones;females lived longer than males. Conclusion: Suffcient supply of blood meal may prolong greatly the longevity of female mosquitoes and thus increases mosquito's fecundity.
