889. ; Henson, R. D.; Gueldner, R. C; and Hedin, P. A. 1973. Constituents 

 of the boll weevil, Anthonomus grandis Boheman: VIII. Lipids and fatty 

 acids in the subcellular particles of pharate pupae. Comp. Biochem. 

 Physiol. A5B: 233-239. 



1. Neutral lipids predominated in the nuclei and mitochondria fractions of 

 pharate pupae of the boll weevil, Anthonomus grandis Boheman, and phospho- 

 lipids predominated in the microsomes. 2. The nuclei and mitochondria lipids 

 containod more llnoieic (18:2) acid than the microsomes. 3. The decrease in 

 18:2 in the microsomes coincided with an increase in 18:3. 4. The average 

 number of unsaturations per molecule of lipid was higher in the phospholipids 

 than in the neutral lipids. 5. Phosphatidyl ethanolamine and phosphatidyl 

 choline comprised 50-70% of all phospholipids in all subcellular components of 

 pharate pupae. 6. Sterols and sterol derivatives were evenly distributed in 

 the nuclei, mitochondria and microsomes of pharate pupae, pupae and adult stages 

 of the boll weevil.

in over-wintered boll weevils, Anthonomus grandis Boheman. Cotnp. Biochem. 



Physiol. 60B: 201-203. 

 1. The neutral lipids decreased from 90 to 55% in male and female boll weevils, 

 Anthonomus grandis Boheman, from May through July in the field. Neutral lipids 

 were consistently higher (30-50%) in males than in females. 2. The wet weight 

 and dry weight decreased 50 and 32%, respectively, from May through July. 3. 

 The concentration of fatty acids in the polar lipids declined from 50 Mg/mg dry 

 wt in May to 10 /Jg/mg in the m-iddle of June. 4. Protein and carbohydrate de- 

 clined from 68 to 73% in the boll weevil from May through July.
