"The University of Pennsylvania vet school (in a study funded by Merial)
found: “Development in the mosquito is temperature dependent, requiring
approximately two weeks of temperature at or above 27C (80F). Below a
threshold temperature of 14C (57F), development cannot occur, and the cycle
will be halted. As a result, transmission is limited to warm months, and
duration of the transmission season varies geographically.”"

发帖数: 26631 | 7 我看了啊， 是说57度以下发育就会停止。
一共需要两周的发育。
但是很难计算每天有多少时间在57度以上哎

而且最低气温的时候aka夜里
你也不会整晚上在外头呆着
而且57也不是绝对的cut off吧
保证蚊子也有怕热跟抗冻的个体差异
基本我觉得柴鱼的意思是
冬天就不用吃药了，比如我们这里冬天都30度而已
春天夏天秋天50度以上就可以开始注意检查和吃药了
而且即使是春天夏天秋天，所有事件同时发生的可能性，也还是很小。
