1953年，在日本东京附近的新滨村和附近的南御德村，C。日本流行性乙型脑炎病毒的主要传播媒介三带喙鹭进入黑冠夜鹭诱捕器的数量是白鹭或鸡诱捕器的3至15倍;蓝喜鹊、树麻雀、黑画眉和灰椋鸟未能吸引大量数量。1956年，在东京附近的两个农村和一个城市，猪吸引了更多的C。tritaeniorhynchus比BCNH或人C.三带喙龙是在距地面50英尺高的陷阱中发现的。媒介蚊子的行为部分解释了鸟类之间病毒感染的不同发生率，自然界中猪感染的高发生率，以及Sagiyama高处树上的雏鸟感染。不管动物有什么吸引C的机制。三带喙龙，它坚持在陷阱1至3天后，删除的动物。其他蚊子的行为与C.三带喙龙C.在所有7种鸟类中，pipiens经常进入诱捕器，并且在诱捕器中被BCNH吸引的次数多于被猪吸引的次数。A.在农村地区，只有在猪饵陷阱中才能发现大量的中华按蚊。其他物种只在少数情况下被发现。微生境影响进入陷阱的蚊子，并有必要研究多个陷阱网站与重复的陷阱。有一次C。三带喙线虫的采集受到与个体诱捕器本身相关的因素的影响，而与诱捕器的设计或位置无关。这些研究强调，仅从蚊子行为的知识来预测病毒生态可能是错误的。
Summary At the Shinhama heronry and nearby Minamigyotoku village near Tokyo, Japan, in 1953, C. tritaeniorhynchus, the major vector of Japanese encephalitis virus in Japan, entered traps baited with Black-crowned Night Herons in numbers 3 to 15 times greater than traps containing egrets or chickens; Blue Magpies, Tree Sparrows, Dusky Thrushes, and Grey Starlings failed to attract significant numbers. In 1956, at two rural and one urban location near Tokyo, pigs attracted and were bitten by many more C. tritaeniorhynchus than BCNH or man. C. tritaeniorhynchus were found in traps as high as 50 feet above ground at the Sagiyama heronry. The behavior of the vector mosquito explained in part the different incidences of virus infection among bird species, the high incidence of swine infection in nature, and infection of nestling birds high in trees at Sagiyama. Whatever animal mechanism exists for attracting C. tritaeniorhynchus, it persisted in traps for 1 to 3 days after removal of the animal. Other mosquitoes behaved differently from C. tritaeniorhynchus. C. pipiens frequently entered traps with all seven species of birds and was attracted to BCNH in traps more than to pigs. A. sinensis was found in significant numbers only in pig-baited traps in rural areas. Other species were recovered only in small numbers. Microhabitats affected entry of mosquitoes into traps and necessitated study of multiple trap sites with duplicate traps. On one occasion C. tritaeniorhynchus collections were influenced by factors related to the individual trap per se and independent of trap design or location. These studies emphasized that predictions of virus ecology from knowledge of mosquito behavior alone may be erroneous.
