10 PROLIFERATION IN CONTROL OF BOLL WEEVIL. 



PROLIFERATION FROM FEEDING PUNCTURES IN SQUARES. 



As the s(iiiare precedes the boll in the natural process of develop- 

 ment and the feedino; puncture precedes oviposition in the attack 

 of the weevil, we shall consider first the observations regarding pro- 

 liferation resulting from feeding punctures made in squares. These 

 observations include nearly 25 varieties of cotton. They are grouped 

 by years and localities in order to bring as closely together as is possi- 

 ble those records which may be considered as most strictly compar- 

 able. The totals and averages for so many seasons and localities 

 should constitute a very fair average statement of the true condition.

a Weighted average. 



The general average for all the various seasons and localities 

 shows that in scpuxres approximately one-half of all feeding punc- 

 tures stimulate proliferation. The highest j)ercentage shown is 75.6 

 per cent in "Jannovitch" (an Egyptian variety), at Victoria, Tex., 

 on October 22, 1903, while the lowest percentage found was 12.9
