抄録

Mark-release-recapture studies with anopheline mosquitoes were conducted 2 times in Northern Thailand in October and November 1995. In the first experiment, 3,744 females of 12 anopheline species were collected, marked and released to examine flight distances. The mosquitoes were recaptured at 5 sites with different distances from the release site (60, 400, 1,000, 2,000, and 2,700 m) by human and buffalo bait collections for 4 days. The recapture rate of the 5 major anopheline species ranged from 0.72 to 1.23%. The recapture rate of An. aconitus, the dominant species of the study area, was 0.92% and 3 marked An. aconitus were recaptured at 2,700 m away from the release site. In the second experiment, a total of 9,374 females of 11 anopheline species were released to estimate the daily survival rate of An. aconitus and confirm flight distance. The recapture rate of An. aconitus was 1.46% and An. aconitus (1), An. minimus (1), An. tessellatus (1) and An. hyrcanus gr. (7) were recaptured at 2,700 m distant from the release site. The survival rates of An. aconitus were estimated as 0.618 and 0.624/day by the modified triple catch method and log-regression analysis, respectively. Degree of anthropophily was evaluated by the ratios of human to buffalo landing rates of released anopheline species. Based on flight distance, survival rate and degree of anthropophily, the vector competence of An. aconitus is discussed.
