Tsetses were eliminated from the island of Zanzibar by releasing sterile
males. What is missing for eradication? Determination. Political will to finance is
lacking, and political strive is an added obstacle. Of course, the real problem is rural
poverty. Note that infected flies usually occur at 1/1,000 flies. Many other different techniques are also PARTIALLY EFFECTIVE against tsetses
like pouron pyrethroids for cattle, BUT they do not control epidemics or give hope of
eradication. All techniques require disciplined cooperation through ALL social levels and
over vast distances. |
