Vector blood-feeding frequency, parity, and ovarian development are important factors that can influence pathogen transmission. Parity rates of the dengue vectors Aedes aegypti and Ae. albopictus were determined from females collected from August 2002 to July 2004 in metropolitan Rio de Janeiro. A high frequency of parous Ae. aegypti (92.9%, n = 550) and Ae. albopictus (99.1%, n = 320) females suggested high survivorship of both species. A total of 69% of wild-caught Ae. aegypti females had blood in the midgut compared to 19% of Ae. albopictus. For Ae. aegypti, red-colored midgut contents were associated with ovaries in early stages of development, and brown-colored midguts were associated with ovaries in late stages of maturation. Ovaries of Ae. aegypti females without blood in the midgut were most frequently in stages I and V of Christophers.
媒介蚊虫的吸血频率、生殖状态和卵巢发育是影响病原体传播的重要因素。2002年8月至2004年7月在里约热内卢市收集的雌性埃及伊蚊和白纹伊蚊这两种登革热媒介蚊虫的生殖率得以确定。已产卵的埃及伊蚊（92.9%，n = 550）和白纹伊蚊（99.1%，n = 320）雌性蚊虫的高频率表明这两个物种的高存活率。总共69%的野生捕获埃及伊蚊雌性蚊虫中肠内有血液，相比之下白纹伊蚊为19%。对于埃及伊蚊，红色中肠内容物与发育早期的卵巢相关，而棕色中肠与成熟后期的卵巢相关。中肠内无血液的埃及伊蚊雌性蚊虫的卵巢最常处于克里斯托弗斯I期和V期。
