Acquired Immunity from Insect Stings

Article metrics


To the query of Mr. Dawson Williams (NATURE. March 4, p. 415), as to whether the mosquito injects a toxin, an affirmative answer may be given. The mosquito has, instead of the two long simple salivary glands of other diptera, a complex system, three glands on each side of its thorax, two of each set unlike the third. All the six ductules from these glands unite so as to carry the secretion to the common salivary duct, and by it to the hypopharyx. The structure of the hypopharyx is the same as that of the sting of a bee, a tubular-pointed organ with a subterminal orifice. The only exit for the discharge of the complex glandular apparatus is into the wound made by the lancet-formed mouth-organs.
