tained only small amounts of llnoleic and linolenic acids. The triglycerides 

 added to the diet appeared to influence the synthesis and accumulation of 

 other fatty acids in the weevil. The percent fatty acid composition of the 

 males, females, and eggs were found to be very similar. The boll weevil did 

 not require a dietary source of vitamin E. Weevils maintained for - i.ree 

 generations on purified diets without added Vitamin E continued to x ly large 

 numbers of eggs.

 The Cotton Insects Physiology Laboratory, Baton Rouge, La., monitored the 

 sterility of boll weevils ( Anthonomus grandls Boheman) produced for mass 

 release in a pilot eradication program in southern Mississippi. Weevils 

 were reared and sterilized at the Robert T. Cast Laboratory, Mississippi 

 State, Miss., during 1972 and 1973. Progressive increases in sterility 

 coincided with improvements in ; the health and vigor of the weevils; an ex- 

 tension of the treatment period; the addition cf a second chemostcrilaiit, 

 hempa, to the busulfan-treated diet; and refinements in the preparation and 

 feeding of chemosterilant diets.
