Toxicant could reduce or eliminate all infestations of H. i. irri- 

 tans if properly applied to cattle twice in 2 successive weeks. 

 Manure pats were sampled after spraying to test effectiveness of 

 the toxicant.

Two methods of monitoring the effect of releasing sterile horn 

 flies into a native population of flies were compared. The first 

 method estimated fecundity and hatchability from horn fly eggs 

 collected from individual manure pats. The second method esti- 

 mated fecundity and hatchability from eggs collected from flies 

 taken from cattle and held in laboratory cages.
