the free acino acids rose from a low point at the prepupal stage, receded at 

 pupal stage 2 and rose to a higher level just before eclosion. (5) The protein- 

 bound acids remained constant, showing little fluctuation; the individual amino 

 aicds followed a similar course.

 behavior of the boll weevil. J. Econ. Entomol. 59: 598-599. 



The influence of color on the feeding of the boll weevil, Anthonomus grandi s 

 Boheman, was determined by the response of the weevil to feeding plugs, with 

 and without the addition of a feeding stimulant, dyed red, orange, yellow, 

 green, blue, or violet, and to undyed plugs. The boll weevils preferred the 

 dyed to the undyed plugs, but discriminated but little among the dyed plugs.

 1. When C-labeled tryptophan-3 was injected into boll weevils, Anthonomus 

 grandis Boheman, the amount of radioactivity in the free amino acids pool 

 dropped quickly at first and then more gradually until the twelfth hr post 

 injection. Incorporation into the lipoprotein and protein fractions also peaked 

 at 12 hr but with the nucleic- acids, incorporation was gradual. 2. All RNA 

 bases were labeled early (4 hr) but complete labeling of the DNA bases did 

 not occur until 18 hr postinfection. The amount of labeling varied with time. 

 3. The lipid fraction was labeled, but activity was too low to determine the 

 extent of incorporation into individual fatty acids. 4. Both ess-jntial and 

 non-essential amino acids were labeled.
