FLEAS AS PESTS TO MAN AND ANIMALS, WITH
SUGGESTIONS FOR THEIR CONTROL.
By F. C. BISHOP,
Entomological Assistant, Southern Field Crop Insect Investigations.
Fleas are of importance to man in two ways: First, as disease
carriers and, second, as parasites or annoyers of man and animals.
The dread disease of man known as bubonic plague has been found
to be transmitted largely, if not entirely, through the agency of
these insects. A disease known as infantile kala azar, occurring
in the countries bordering the Mediterranean Sea, is probably also
transmitted by them, and a species of tapeworm which infests dogs
and occasionally people has been found to pass at least one stage in
the dog flea, then gaining entrance to a new host by the swallowing
of crushed or living fleas. As parasites of man and animals fleas
are of considerable importance aside from disease transmission.
In many instances they have been known to render houses unin-
habitable for a time, and certain species cause considerable loss
among poultry as well as annoyance to other animals.
LIFE HISTORY AND HABITS OF FLEAS.
It should be borne in mind that there are a great many different
kinds of fleas. Most of these are of no importance to man, as they
feed on various wild birds and mammals. Nearly all species have
some one host upon which they prefer to live, but they may feed
upon other animals and often thrive upon them.
