They claim there that the yellow fever mosquito does not bite during the daytime after she has laid her eggs, and that she will not lay her eggs until about three days after she has fed on blood, therefore a Stegomyia that bites during the day will not carry the yellow fever because she is too young.
For some time it was claimed that this species would breed only in clean water, but it has been found that it is not nearly so particular, some even claiming that it prefers foul water. I have seen them breeding in countless thousands in company with Stegomyia scutellaris and Culex fatigans in the sewer drains in Tahiti in the streets of Papeete.
The natives and negroes are immune to yellow fever, but not to malaria. As most of us know, Major Ross of the I.M.S., in 1896, proved the connection of malaria with the anopheles mosquito; and in 1902 Mr Reed of the U.S. Health Commission tracked the yellow fever to the stegomyia mosquito. Yellow fever requires six days to develop.
It should be noted that the stegomyia insect is common in India, but luckily has not yet been infected with the germ of yellow fever. And it may also be here mentioned that the connection between bubonic plague and rats, and the fleas that infest them, was discovered by the Japanese scientist, Kitasato.
