The Female of the Species 



The relentless battle between man and insects is often 

 carried out indirectly: the insects destroy man's food, or, in 

 the case of flies, contaminate it with disease germs. But 

 there is nothing indirect about the mosquito. When you 

 sit out on your lawn on a fine summer's evening, you are soon 

 attacked from all sides by a buzzing, blood-thirsty horde, and 

 your tender epidermis is soon punctured in numerous places 

 by sharp, hollow swords. Nor is it any consolation to know 

 that the attack would be twice as bad if the males, instead of 

 just the females, had mouth-parts capable of piercing your 

 skin. 



Mosquitoes belong to that class of insects known as 

 Culicidae, a very large family indeed, being composed of a 

 few subfamilies and numerous species. Not all of the species 

 attack man: in fact, many of the species aren't blood-suckers 

 at all, and of the blood-suckers many prefer to feast on birds 

 and on mammals other than man. To keep from getting 

 too technical, let's limit our attention to the Culex, Anopheles, 

 and Aedes mosquitoes, for these members of the subfamily 

 Culicinae comprise our pesky household mosquitoes as well 

 as the deadly carriers of malaria and yellow fever. 



The various species of the genus Culex are supposed to 

 be harmless, as far as the transmission of human diseases are 

 concerned, but no one will disagree with the statement that 

 the word "nuisance" is a very mild term to apply to these 

 widespread destroyers of our peace and quiet. And are we 

 sure that they don't carry disease from man to man? It is
