Livestock and Poultry. (1) Obtain complete information on biology 
and distribution of livestock pests; (2) Evaluate damage caused by

Ent. 905 
A Study of the aoe and Control of the Pest Mosquitoes of 
Northern Minnesota. To (1) conduct a general survey of mosquitoes 
and mosquito breeding places to determine which localities and 
species are most important; (2) make detailed study of the life 
cycle and breeding places of the species found to create the 
greatest nuisance; (3) try to classify breeding places by means 
of obvious biological indicators so potential sources of large 
mosquito populations can be anticipated and control campaigns 
carried out intelligently; (4) study dispersion patterns of princi- 
pal species to discover extent of areas which might be involved if 
control programs are to be effective.
