Horn flies did not show a definite diurnal rhythm in oviposi- 

 tion. There was a single peak adult abundance during the sum- 

 mer. Predators Philonthus cruentatus Gmelin, Sphaeridhim sca- 

 rabaeoides (L.), and S. lunatum (F.) were chiefly responsible 

 for horn fly suppression in B.C. Horn fly parasites and dung 

 burying beetles were scarce.

Of the 1,002 flies collected from lesions on cattle and buffalo, 

 64.6 percent were H. i. exigua.

 Haematobia irritans. Insect Biochem. 5(4): 387-398. 



Measurements were made of the free sugar, glycogen, and lipid 

 levels in flies treated with a 2.0 krad dose of ionizing radiation. 

 Glycogen levels were depressed in males but remained unchanged 

 in females. Triglyceride levels in both sexes were 50 percent lower 

 than the control group, but there was no effect on the distribu- 

 tion of fatty acids among the various lipid classes.

effects of ionizing radiation on adult horn flies, Haematobia irri- 

 tans. Insect Biochem. 5(1): 35-42. 



Adult flies were irradiated from a 137Cs source and analyzed 

 for physiological (free) amino acids and for total (hydrolysates) 

 amino acids. Assays showed that irradiated flies had increased 

 levels of asparagine — glutamine and creatinine — but neither am- 

 monia nor total amino acids were affected. Several compounds 

 previously unreported in insects were found to occur in horn 

 flies.

Extracts of whole adult horn flies contained 11.0 ?/-mole crea- 

 tinine and 0.5-1 i^-mole creatine phosphate per gram tissue.
