水生双翅目4种，分别为三重大蚊Tipula triplex步行者（Tipulidae）、棒足双翅蝗Bittacomorpha clavipes（F.）（Ptychopteridae）、Chaoborus punctipennis（Say）（Culicidae）和Tendipes sp.（Tendipedae），在无菌条件下收集，并用于消毒无菌土壤-水提取物。在51个培养液中鉴定出21个藻类属、5个原生动物属、1个藓类原丝体属和链格孢属。通过“Student t检验”进行比较，结果显示B. clavipes携带的藻类和原生动物显著多于其他三种昆虫，T.三倍体比蠓携带更多的昆虫在超过18%的培养物中发现了蓝绿色藻类鱼腥藻属、线囊藻属、色球藻属和席藻属，以及绿色藻类衣原体属、小球藻属、绿球藻属和原球藻属。原生动物被发现在较低的频率。这表明，这些可行的藻类和原生动物所携带的这四种昆虫跨越陆地障碍。全文见JSTOR
Four species of aquatic Diptera, Tipula triplex Walker (Tipulidae), Bittacomorpha clavipes (F.) (Ptychopteridae), Chaoborus punctipennis (Say) (Culicidae), and Tendipes sp. (Tendipedidae), were collected aseptically and used to inoculate sterile soil—water extract. Twenty—one genera of algae, five Protozoa, a moss protonema and Alternaria were identified in the 51 cultured washings. Comparisons by "Student's t" showed that B. clavipes carried significantly more algae and Protozoa than the other three insect species, and T. triplex carried more than the midges. Found in over 18% of the cultures were the blue—green algae Anabaena, Anacystis, Chroococcus and Phormidium, and the green algae Chlamydomonas, Chlorella, Chlorococcum and Protococcus. The protozoans were found at lower frequencies. It is suggested that these viable algae and Protozoa are carried by these four insect species across land barriers. See full-text article at JSTOR
