In 2 forested areas near Belém (Para State, Brazil), 2 Haemagogus and 6 Sabethes species were marked released and recaptured in May 1989 and in April 1993. The recapture rates were high, 4.9 and 13.1% for Haemagogus and Sabethes spp., respectively. For Haemagogus janthinomys Dyar, females were recaptured until 27 d after release. The duration of the gonotrophic cycle was between 5.0 and 9.5 d and the survival rate was 0.90-0.92. Haemagogus leucocelaenus (Dyar & Shannon) was recaptured once, 21 d after release. Twelve Sabethes chloropterus (Von Humboldt) were recaptured, with a peak at 15-18 d; 1 female was recaptured at 44 d, indicating extended survival. Seven Sabethes amazonicus Gordon & Evans and 7 Sabethes cyaneus (F.) were recaptured, mostly at 14-39 d. These results indicate that Haemagogus and Sabethes spp. have a gonotrophic cycle in nature longer than inferred from laboratory studies, and that cycle length varies seasonally. The capacity of these species to sustain epizootics or epidemics of arboviruses may depend on local weather, with risk greatest at the end of the rainy season.
1989年5月和1993年4月，在贝伦（巴西帕拉州）附近的2个林区，对2种赫氏蚊属和6种萨氏蚊属蚊虫进行了标记释放和再捕获。再捕获率很高，赫氏蚊属和萨氏蚊属的再捕获率分别为4.9%和13.1%。对于雅氏赫氏蚊，雌蚊在释放后27天仍有被再捕获的情况。生殖营养周期持续时间在5.0至9.5天之间，生存率为0.90 - 0.92。白纹赫氏蚊在释放后21天被再次捕获过一次。12只绿翅萨氏蚊被再捕获，在15 - 18天出现峰值；1只雌蚊在44天被再捕获，表明其存活时间延长。7只亚马逊萨氏蚊和7只蓝萨氏蚊被再捕获，大多在14 - 39天。这些结果表明，赫氏蚊属和萨氏蚊属在自然中的生殖营养周期比实验室研究推断的更长，且周期长度随季节变化。这些蚊种维持虫媒病毒流行或暴发的能力可能取决于当地天气，在雨季末期风险最大。
