1. Oxygen uptake was measured in laboratory diet-fed 1- to 15-day old male and 

 female boll weevils of the ebony strain. 2. 0^ uptake was found to be between 

 27' 24 to 6*A5 hi 02/mg wet wt per hr for males and between 26*37 and 5*64 ^1 

 O^/mg wet wt per hr for females. 3. Peak O2 uptake for males was recorded when 

 they were 4 and 12 days old. 4. Peak O2 uptake for females was recorded when 

 they were 6, 10, and 14 days old.

 1. Oxygen uptake was measured in 1-to 15-day old male and female boll weevils of 

 the ebony strain that were fed cotton squares (buds). 2. O2 uptake was found to 

 range between 19.51 and 10.64 ul O^lvig wet wt/hr for males and between 17.6 and 

 11.1 ul 02/mg wet wt/hr for females. 3. Peak O2 uptake for males was recorded 

 when they were 5 and 11-12 days old. 4. Peak uptake for females was recorded 

 when they were 6 and 12 days old.

sterility in boll weevils. Entomol. Exp. Appl. 17: 452-453. 

 Since disease and malnutrition also have an effect on the vigor of boll weevils, 

 such a test as we have described can be used oilSy when the procedures in the 

 rearlSig facility are such as to maintain vigor and when tests are mad^ if disease 

 or malnutrition is suspected. These potential problems notwithstanding, the 

 locomotor test was used successfully during the 1973 phase of the PBWEE to deter- 

 mine the degree of sterility of chemosterilant-treated male boll weevils. It was 

 especially valuable when the results of tests made at the beginning of the re- 

 lease program indicated that the boll weevils were not being fed an adequate quan- 

 tity of chemosterllant to render them sterile. The deficiency was immediately 

 corrected by feeding the weevils the chemosterllant an extra day. It would have
