 To COLLECT AND PRESERVE MOSQUITOES 



How TO COLLECT MOSQUITOES 



Mosquitoes may be collected in two ways : 



1. By capturing the adult flies. 



2. By breeding out from larvae and nymphae. 

 i. Search, in the daytime in houses, huts, and 



out-houses, at the base of large trees, amidst brushwood 

 and other dark or shaded places. Anofihelines, how- 

 ever, are rarely caught except in huts and out-houses. 

 They are especially fond of cow-sheds and the darker 

 portions of the eaves of huts. 



Some species of mosquitoes may be caught by 

 sitting with a light near a white wall or suspended sheet, 

 or inside a tent, near a jungle or marsh. Culex and 

 Taeniorhynchus may be found sitting on the surface 

 just beyond the brightly illuminated area. Anofhelines 

 are rarely caught in this way, but one species at least 

 (My. barbirostris) appears to be attracted by light, 

 and was caught by us on an illuminated sheet at night, 

 near swampy land. 



In searching for adult Ano-phelines, as many places 

 as possible should be examined, as the distribution of 

 some species is very local. 



If the captured insects appear to have fully 

 matured ovaries, some of these should be placed in
