为了将吸血功能归因于蚊子的唾液，我们确定这种分泌物是否可能限制叮咬行为的初始探测阶段。当唾液导管被切断时，蚊子对宿主的探测确实延长了，但当蚊子被喂食包含在膜下的人造食物时，这种延长就不存在了。在体外，浊度测定表明，唾液抑制ADP和胶原介导的血小板聚集。ATP和ADP被唾液水解，这种腺苷三磷酸双磷酸酶活性部分解释了观察到的对血小板的影响。我们的结论是蚊子的唾液功能，促进血管的位置。
In order to ascribe a blood feeding function to the saliva of mosquitoes, we determined whether this secretion may limit the initial probing phase of biting behaviour. The probing of hosts was indeed prolonged when the salivary ducts were severed, but this prolongation was absent when mosquitoes were fed on an artificial meal contained beneath a membrane. In vitro, turbidometric assays demonstrated that saliva inhibits the ADP- and collagen-mediated aggregation of platelets. ATP and ADP were hydrolysed by saliva, and this apyrase activity explains, in part, the observed effect upon platelets. We conclude that the saliva of mosquitoes functions by facilitating location of blood vessels.
