Chapter XII 
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. Anophelines , 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 
T aeniorhynchus may be found sitting on the surface 
just beyond the brightly illuminated area. Anophelines 
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 Anophelines , 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
