ANOPHELES PROPAGATION AREAS 

 WATER CONTAINERS 



nPHE larvae of Aedescalopus and Anopheles are 

 ■'■ seldom found in the same water. On the 

 Isthmus the larvae of the latter are seldom found in 

 containers, while Aedes calopus axe found only in 

 containers near inhabited buildings. If containers 

 are upset or their contents enter into a pond or 

 ditch the larvae of Aedes calopus will develop to ma- 

 turity; again, if broad fiat containers are so placed 

 that vegetation grows in them, or if they are covered 

 up in the grass and gather vegetable matter, dead 

 leaves, twigs, etc., resembling natural breeding 

 places, Anopheles will at times be found in them, 

 but these conditions rarely occur and are not 

 of practical importance. Isthmian Anopheles are 

 not container breeders, and the sum total produced 

 by water containers is very small. They are 

 found occasionally in large wells or cisterns where
