The plant tissue feeding of Anopheles sergentii Theobald, An. claviger Meigen, Culex pipiens Forskål and Aedes caspius Pallas (Diptera: Culicidae) was investigated. The relative frequency of plant feeding was compared to the general intake of sugar in different seasons and in different habitats in Israel. The study shows that mosquitoes feed on sugar-poor plant tissue in the lack of better options. Optimal conditions were in the sugar-rich En Fesha oasis, where plant tissue was found in only 0.3% of An. sergentii females, and, except for the winter, about 80% of females were sugar positive and the gut content was equivalent to 72.3 +/- 1.6 microg sucrose. By contrast, in the dry season in the desert, guts of 46.3% An. sergentii females contained plant tissue residues, only 46.0% were sugar positive, and the gut-content was less than a tenth, the equivalent of 5.6 +/- 0.9 microg sucrose. Age grouping of contemporary, desert An. sergentii showed that the growing population consisted mostly of newly emerged adults, as 80.2% of the females were nulliparous and only 12.1% of them survived one gonotrophic cycle.
对塞尔根按蚊（Theobald）、棒形按蚊（Meigen）、尖音库蚊（Forskål）和里海伊蚊（Pallas）（双翅目：蚊科）的植物组织取食情况进行了研究。将植物取食的相对频率与以色列不同季节和不同栖息地的糖分总体摄入量进行了比较。研究表明，在缺乏更好选择的情况下，蚊子会取食含糖量低的植物组织。最佳条件存在于糖分丰富的费沙绿洲，在那里仅0.3%的塞尔根按蚊雌蚊被发现有植物组织取食情况，并且除冬季外，约80%的雌蚊糖分检测呈阳性，肠道内容物相当于72.3±1.6微克蔗糖。相比之下，在沙漠的旱季，46.3%的塞尔根按蚊雌蚊肠道含有植物组织残渣，只有46.0%的雌蚊糖分检测呈阳性，且肠道内容物不到十分之一，相当于5.6±0.9微克蔗糖。对沙漠地区当代塞尔根按蚊进行年龄分组显示，不断增长的种群主要由新羽化的成虫组成，因为80.2%的雌蚊未产卵，其中只有12.1%的雌蚊经历了一个生殖营养周期存活下来。
