LIFE-TABLE ATTRIBUTES OF ANOPHELES-ALBIMANUS (WIEDEMANN) UNDER CONTROLLED LABORATORY CONDITIONS

The life-table attributes of a laboratory-colonized strain of Anophele s albimanus Wiedemann from El Salvador were investigated under control led environmental conditions (26+/-2 degrees C, 60+/-2% RH, and 16:8 L :D photoperiod). Larvae pupated seven days after eclosion and the adul ts emerged on day eight. Adult emergence success was 91% and sex ratio was not significantly different from 1:1. Females took a blood meal o ne day after emergence and laid eggs two days later. The mean lime of reproduction was 10.8 days and the expectation of life at emergence wa s 18.8 and 14.1 days for females and males, respectively. The daily su rvivorship of females at emergence was 0.97, and their net reproductiv e rate, age at mean cohort reproduction, instantaneous rate of increas e, and mean generation time was 309.2, 10.8 days, 0.319, and 18 days, respectively. The life expectancy of females 10 days after emergence w as 13.4 days, and they were capable of taking four to six additional b lood meals.
