The preceding chapter has indicated briefly <strong>the</strong> important re-<br />
lations that <strong>mosquitoes</strong> bear to man. It is strange, that, know-<br />
ing <strong>the</strong>se conditions, man has not made greater efforts to con-<br />
trol <strong>the</strong>m. Only where great outbreaks <strong>of</strong> diseases have<br />
occurred or where important national developments are under-<br />
taken, or due to devastating sickness in time <strong>of</strong> war or where<br />
public sentiment has been sufficiently aroused, have peoples<br />
organized great anti-mo,squito campaigns. The results have<br />
been <strong>of</strong> unprecedented success. Witness <strong>the</strong> work in Havana,<br />
New Orleans, <strong>the</strong> Panama Canal Zone, New Jersey, Ishmailia,<br />
Italy, parts <strong>of</strong> Greece, Palestine, <strong>the</strong> work at Singapore, etc.<br />
All <strong>the</strong>se campaigns were led by able men supported by govern-<br />
ments and various o<strong>the</strong>r agencies and <strong>the</strong>ir main object was <strong>the</strong><br />
reduction <strong>of</strong> mosquito-borne disease. Yet despite this, vast<br />
areas <strong>of</strong> <strong>the</strong> most fertile regions <strong>of</strong> <strong>the</strong> world suffer from<br />
mosquito-borne diseases. H<strong>of</strong>fman in 1916 made a plea and<br />
presented a tentative plan for <strong>the</strong> eradication <strong>of</strong> malaria<br />
throughout <strong>the</strong> western hemisphere. This plea is based on <strong>the</strong><br />
knowledge “that malaria is perhaps <strong>the</strong> most important <strong>of</strong><br />
human diseases, and though it is not <strong>of</strong>ten directly fatal, its<br />
wide prevalence in almost all warm climates produce an enor-<br />
mous amount ol sickness, and mortality.”<br />
The problem <strong>of</strong> mosquito reduction involves two distinct<br />
points <strong>of</strong> view; ( 1) that <strong>of</strong> <strong>the</strong> public health <strong>of</strong>ficial who has<br />
been and still is largely concerned with <strong>the</strong> reduction <strong>of</strong> mos-<br />
