Mosquitoes in Relation to Agricultural Production and 
Veterinary Science. (1) Evaluate effect of mosquitoes on pro- 
duction of meat, milk, and animal products in certain parts of 
state and development of procedures for reducing economic loss; 
(2) Define importance of mosquitoes in management of equines in 
state and research on systemic and surface repellents for use 
with animals; (3) Clarify role of mosquitoes in transmission of 
virus and protozoan diseases of domestic birds and animals to 
learn reservoirs of such diseases. 
Ent. 212 Coop. HEW-USPHS 
The Biology and Control of Vectors of Anaplasmosis. To 
develop and demonstrate more effective means of controlling the 
vectors of anaplasmosis and to intensively study the biologies 
of these arthropods so that the most effective time for control 
may be found. 
Vet. 312 Coop. ARS 
The Control of External Parasites. To (1) develop effective 
repellents to protect animals from external parasites, especially 
those with resistance to common toxicants; (2) evaluate effective- 
ness and hazards of new chemicals as pest toxicants; (3) determine 
best methods to apply insecticides to animals, especially auto- 
matic sprayers, rubbing posts and treadle machines; (4) obtain 
biological data to assist in above objectives; and (5) obtain 
adequate data indicating gains to be expected from parasite control.

Insect Pests of Livestock. To study (1) life history patterns 
of insects associated with livestock and learn which stage of de- 
velopment is most susceptible to control; (2) rate at which insect 
pests of livestock develop resistance to insecticides; (3) new 
insecticides and techniques as to application for control and effect 
of such procedures on animals. 
Zool., Ent. 1/261! 
Insects Affecting Man and Animals. to (1) compare repellents 
against several varieties of biting flies of dairy and beef cattle; 
(2) determine best methods of applying repellents and insecticides 
with emphasis on automatic treadle sprayers and back rubbers; (3) 
test the better repellents against horseflies and deerflies in parts 
of S. C. where they occur in large numbers, causing much annoyance 
to animals; (4) test insecticides using residual spray and bait 
methods for housefly control in dairy barns and other buildings; 
(5) determine most effective materials and methods of application 
of controlling ticks and chiggers of man and animals; and (6) 
test insecticides and methods of application for control of lice 
and grubs on cattle.
