 Sun Oil 7N® and water) were applied by plane to 2-ha replicated plots of cotton 

 in Mexico for control of Anthonomus grandis Boheman. All treatments were sig- 

 nificantly different from the check and were highly effective in inhibiting 

 boll veevil egg hatch. These were no significant differences in effectiveness 

 among treatments.

 insects: oxidation of hexadecane-l--'-^C in the boll weevil and t'ue house 

 fly. Ann. Entomol. Soc. Am. 62: 891-894. 



The boll weevil, Anthonomus grandis Boheman, and the house fly, Musca domestica 

 L., metabolized injected hexadecane-l--^'*C. Two metabolic products were isolated, 



CO2 and fatty acids. When hexadecane was administered by injection, a 

 characteristic release pattern of CO^ was noted which included an initial 



peak of CO output. This peak was followed by a lag period then by a 2nd 



14 

 peak of production. Hexadecane-1- C also was given to the boll weevil in its 



diet and was converted to labeled fatty acids. The principal labeled fatty 

 aicdt found contained 16 carbon atoms, suggesting direct conversion of hexa- 

 decane to fatty acid by terminal oxidation. C16:0 predominated in the boll 

 weevil, and C16:l in the house fly, but radioactivity was also found in C18:0 

 and C18:J. fatty acids. The fatty acids were distributed to triglycerides, 

 phospholipids, sterol esters, and to other fatty acid-containing lipid 

 fractions.
