我们比较了Anopheles Oswaldoi和An的敏感性。基于蚊子和孢子虫的蚊子的比例，康德利通过疟原虫感染。在巴西亚马逊的英亩和朗多尼亚州捕获了藻类，并用于获得F1后代。成年人出现后，剖析了每个家族的蚊子的雄性生殖器，以将其识别为A。 OSWALDOI或AN。 Konderi。场捕获的F1祖奥斯瓦尔多伊，an。 Konderi和An。 Darlingi（用作对照）同时在疟原虫感染的血液上喂食。喂食后第10-12天解剖蚊子，并检查是否存在卵囊和孢子虫。两个Oswaldoi和An。 Konderi在中肠发展了卵囊，但是，An的卵囊阳台的百分比。 Oswaldoi（13.8％）高于An。 Konderi（3.3％），只有一个。奥斯瓦尔多伊（Oswaldoi）患有孢子虫（Sporozoites）（占阳性的6.9％）。感染率卵囊和孢子虫的达令族范围从22.5％到30.0％。这些结果表明An。 Oswaldoi可以传输P，Vivax：并建议它比AN更容易受到影响。 Konderi。虽然一个。奥斯瓦尔多伊（Oswaldoi）是一种源自和动物噬菌体，它可能参与疟疾的传播，因为它可能发生在英亩状态。
We compared the susceptibility of Anopheles oswaldoi and An. konderi to infection by Plasmodium vivax based on the proportion of mosquitoes presenting oocysts and sporozoites. Anophelines were captured in the State of Acre and Rondonia, Brazilian Amazon, and used to obtain F1 progenies. After emergence of adults, male genitalia of mosquitoes of each family were dissected in order to identify them as either An. oswaldoi or An. konderi. F1 progenies of field-captured An. oswaldoi, An. konderi and An. darlingi (used as control) were fed simultaneously on P. vivax-infected blood. Mosquitoes were dissected on day 10-12 after feeding and examined for the presence of oocysts and sporozoites. Both An. oswaldoi and An. konderi developed oocysts in the midguts, however, the percentage of oocyst-positive mosquitoes for An. oswaldoi (13.8%) was higher than for An. konderi (3.3%), and only An. oswaldoi developed salivary infection with sporozoites (6.9% of positivity). Infection rates in An. darlingi ranged from 22.5% to 30.0% for both oocysts and sporozoites. These results indicate that An. oswaldoi can transmit P, vivax: and suggest that it is more susceptible than An. konderi. Although An. oswaldoi is an exophilic and zoophilic species, it may be involved in malaria transmission as possibly occurred in the State of Acre.
