作者在实验室观察中发现蚊虫完成一个生殖营养周期需多次吸血。有两种方法鉴定蚊虫的多次吸血率:一是血清学方法,多次吸取的血液来自2个以上不同种宿主时,此法较好。但是如果吸取的血液是来自2个相同的宿主或亲缘相近以及血液消化后抗原性已消失时,则此法不理想。另一方法是组织学 In laboratory observations, the authors found that mosquitoes need to vampue multiple times to complete a reproductive nutrition cycle. There are two ways to identify mosquito multiple vampire rates: First, serological methods, multiple lessons of blood from more than two different hosts, this method is better. However, this method is not ideal if the aspirated blood is from two identical hosts or relatives and the antigenicity has disappeared after digestion of the blood. Another method is histology
