From 1977 to 1981, studies were conducted on a farm at Mica where Aedes furcifer had been a vector during an epidemic of chikungunya virus in 1976 to determine whether the virus persisted in this mosquito, the likelihood of vertical transmission, and whether any other Aedes species could have been vectors. Aedes furcifer/cordellieri was the only prevalent tree hole Aedes which fed readily on monkeys and humans and occurred through the summer until the onset of winter. Virus was not isolated from 7,241 females and 4,052 males of this group, which were largely Ae. furcifer and which included a sample of the first post-epidemic population. Five additional Aedes species were prevalent in bamboo pots, 3 of which (Ae. aegypti, Ae. fulgens and Ae. vittatus) were shown to be competent laboratory vectors. Virus was not isolated from a sample of 13,029 such newly emerged mosquitoes representing the first post-epidemic population. It is concluded that Ae. furcifer is an epidemic-epizootic vector which does not maintain the virus at Mica and that no other mosquito species could have been important vectors.
1977年至1981年期间，在云母山的一个农场开展了研究，该地在1976年基孔肯雅病毒流行期间，埃及伊蚊曾是传播媒介。此次研究旨在确定该病毒是否在这种蚊子体内持续存在、垂直传播的可能性，以及是否有其他伊蚊种类可能成为传播媒介。埃及伊蚊/科氏伊蚊是唯一常见的树洞伊蚊，它很容易叮咬猴子和人类，整个夏季直至冬季开始时都有出现。在该组的7241只雌蚊和4052只雄蚊中未分离到病毒，这些蚊子主要是埃及伊蚊，其中还包括疫情后第一代种群的一个样本。另外有5种伊蚊在竹罐中很常见，其中3种（埃及伊蚊、亮黑伊蚊和带纹伊蚊）经证实是合格的实验室传播媒介。在代表疫情后第一代种群的13029只新羽化蚊子的样本中未分离到病毒。得出的结论是，埃及伊蚊是一种流行-动物病传播媒介，但在云母山不会维持病毒传播，且没有其他蚊子种类可能成为重要传播媒介。
