1984年7月至1985年2月，采用冷蒽酮反应对美国加利福尼亚州克恩县收集的库蚊进行了果糖检测。总体而言，夏季（7 - 9月）采集的350只雌性果蝇中75%和251只雄性果蝇中68%的果糖呈阳性。寻找寄主的雌性在后半夜摄入果糖。果糖在一生中反复摄入，因为空腹、血喂养、妊娠和产母的雌性表现出相当比例的果糖阳性。雄性在黄昏时成群结队，然后在晚上摄入果糖。雌性在进入滞育（10 - 11月69只雌蜂中有62%）、滞育（12 - 1月175只雌蜂中有42%）和结束滞育（2月75只雌蜂中有78%）时摄入果糖。越冬雌性种群由移动和久坐组成。移动的部分，停留在更暴露的微栖息地，如厕所、桥梁和红盒子，经常摄入果糖，包括一些没有滞育的雌性。久坐的部分，通常休息在更受保护的冬眠场所，如啮齿动物的洞穴，灌木堆和瘤巢，很少摄取果糖，主要由滞育的雌性组成。在滞育终止期间，久坐成分启动卵巢发育，从冬眠中退出，摄入果糖，并在更多暴露的微生境中休息，从而增加了暴露休息部位的雌性丰度。
Culex tarsalis collected in Kern County, California, USA, were tested for the presence of fructose from July 1984 through February 1985 using the cold anthrone reaction. Overall, 75% of 350 females and 68% of 251 males collected during summer (July-September) were fructose positive. Host-seeking females ingested fructose during the 2nd half of the night. Fructose was ingested repeatedly throughout life, since empty, blood-fed, gravid, and parous females exhibited comparable percentages of fructose positivity. Males ingested fructose at night after swarming at dusk. Females ingested fructose when entering diapause (62% of 69 females in October-November), diapausing (42% of 175 females in December-January), and terminating diapause (78% of 75 female in February). Overwintering female populations consisted of mobile and sedentary components. The mobile component, which rested in more exposed microhabitats such as privies, bridges, and red boxes, frequently ingested fructose and included some females that were not diapausing. The sedentary component, which generally rested in more protected hibernacula such as rodent burrows, brush piles, and Neotoma nests, infrequently ingested fructose and consisted mostly of diapausing females. During diapause termination, the sedentary component initiated ovarian development, egressed from hibernacula, ingested fructose, and rested in more exposed microhabitats, thereby increasing female abundance at exposed resting sites.
