176 MOSQUITOES 



{Third Cirrnlar, jono.] 



CONTINUE TO FIGHT THE MOSgUlTO. 



Although it i.s greatly diminished in numbers, even to the ex- 

 tent of being no longer a serious trouble, yet by its unmistakable 

 presence here and there the uujsquito has nuule it evident that 

 all of them are not dead. The success of the plan has far exceed- 

 ed our expectations for the first season. All that is needed now 

 to eliminate them as a feature of this community is to keei) up 

 the tight diligently until November, when we will take a rest 

 until the next season. The chances are that what we will tlo 

 next year will be mainly as a "vvise precaution against the i)0!ssi- 

 ble recurrence of the pest. That you may not forget the history 

 of this insect and why it is possible to destroy them by the use 

 of oil. I repeat a [)ublication made once before.

How the Mosquito is Bred. 



Its germinal period is often about twenty-five days from the 

 laying of the mo.s(piito-egg to the full maturity of the insect, of 

 which time only about three days are spent in the eggs. The 

 average germinal period is about three weeks. I say "about" 

 for the time is not always exactly the same, depending, as it 

 does, very much upon the condition of the weather and water. 



The female lays ;ibout 300 eggs at a time in some jiond, cistern, 

 tank, cesspool, rain-barrel, or any quiet pool t>f water. The 

 eggs are glued together in the shape of a pretty little boat ;nid 

 left to float and hatch. They retain this " wiggler" condition 

 for from live to fifteen days, remaining all the time in the water 

 but changing their skins several times.
