lines caused similar feeding responses in Anthonomus grandls Boheman, in the 

 rolled plug assay. The total fatty acids in the glanded and glandless lines 

 did not vary significantly, but the phospholipids and glycolipids of glanded 

 lines contained 50% more fatty acids than did those of the glandless lines. 

 This difference resulted primarily from differences in the amounts of un- 

 saturated fatty acids, linolenic acid (C-,g:2). About 50% of the total fatty 

 acids in the glandless lines were contained in a highly polar lipid complex 

 that was re"ioved from silicic acid by hydrolysis with an acid solution.

 boll weevil from monoterpene precursors. Insect Biochem. 9: 293-294. 



Biosynthesis of the four monoterpene compounds that comprise the sex pheromone 

 of the male boll weevil, Anthonomus grand is , was demonstrated by using a mix- 

 ture of geraniol and nerol. An average 2.4% of the administered radioactive 

 alcohols was incorporated into the pheromone components. The amount of radio- 

 activity incorporated into each pheromone component indicated that these two 

 isomeric alcohols are incorporated directly into the pheromone biosynthetic 

 pathway,

1. The dry weight of diapausing boll weevils increased from 26 to 68% from 

 November to March. 2. The concentration of fatty acids in the neutral lipids 

 averaged 130.2 ± 19.6 yg/mg dry weight. The total fatty acids declined to 

 50.0 ± 1 /Jg/mg dry weight over the period studied. 3. The concentration of 

 fatty acids in the polar lipids averaged 5.6 ± 1.6 ^g/mg dry weight; the 

 range was 15.3-1.0 Mg/mg dry weight. 4. The average concentrations for pro- 

 tein and for carbohydrate were 337.0 ±62.1 and 64.8 ug/mg dry weight, 

 respectively.
