source in nat'ire. Most variation in short-wave radiation input is offset by 

 changes in rate of convected heat loss. Latent heat losses amounted to 10% of 

 the convected heat loss under bright light and up to 25% at light levels simu- 

 lating cloud cover. It was concluded that because of the difficulty in esti- 

 mating thermal radiant heat fluxes in nature, an accurate prediction of insect 

 temperature from energy balance calculations would be impossible.

 D cotton geraplasm. Crop Sci. 14: 911. 



Georgia Super D cotton ( Gossypium hirsutum L.), a breeding line, was released to 

 plant breeders in April 1973 by the University of Georgia Coastal Plain Experiment 

 Station, Tifton, Georgia. Georgia Super D is unique in that it contains five 

 genetically controlled characters that have shown resistance to boll weevil 

 ( Anthonomus grandis ), bollworms ( Heliothis sp.), and boll-rotting organisms. 

 These characters are red plant color, frego bract, okra leaf, smooth leaf, and 

 nectariless. The line is also homozygous for glandless stem (gl-,) and has re- 

 duced glands in seed and foliage (gl2) but is not homozygous and a small per- 

 centage of plants with normal glands in foliage and seed can be found.

 biochemical profile for mass-reared boll weevils (Coleoptera: Curculionidae) . 

 Comp. Biochem. Physiol. 53C: 9-12. 



1. A simplified biochemical profile consisting of whole body levels of cholesterol, 

 lipid, uric acid, and soluble protein was obtained on mass-reared Anthonomus 

 grandis Boheman of three adult ages for 8 successive weeks representing four 

 generations. 2. All parameters showed significant variation with adult age, 

 sex, and chemosterilant treatment. 3. Levels of cholesterol, uric acid, and 

 soluble protein were significantly depressed in weevils treated with busulfan. 

 4. The feasibility of obtaining biochemical data on large numbers of insects
