12 PROLIFERATION IN CONTROL OF BOLL WEEVIL. 
field. While practically one-half of the squares attacked showed 
proliferation, a far greater proportion of.the locks attacked by the 
weevil showed a similar iormation. 
From these records it appears that 55 per cent of the nearly 9,000 
locks examined received feeding punctures only. Among the locks 
thus injured, an average of slightly over 81 per cent showed distinct 
evidence of proliferation. A comparison with Table I indicates that 
in bolls proliferation occurs from feeding punctures in a higher per- 
centage of cases than it does in squares. The records upon Pachon 
and Korean cottons were included in the table because of the special 
interest attached to these varieties, but the data regarding them 
are too meager to be reliable in drawing definite conclusions regarding 
proliferation in them, and they should be excepted in making a com- 
parison of varieties. It is to be regretted that the two varieties 
mentioned produced so little fruit at Dallas, Tex., that more extensive 
data regarding them could not be obtained, and the fruiting occurred 
so late in the season that no bolls could mature. The range in the 
percentage of cases in which proliferation results from feeding punc- 
tures in bolls is not so great as it appears to have been in squares. 
This fact may possibly be due to more uniform climatic and cultural 
conditions, as nearly all the records for bolls were made from mate- — 
rial collected in one locality at the same time. . 
These records appear to the writer to show a remarkable uniformity, 
and to indicate that among the 15 varieties mentioned in the table — 
which are most clearly comparable there is little difference in the 
natural tendency to proliferate in response to feeding injuries made 
by the weevil in bolls. | 
INFLUENCE OF DIFFERENT LOCALITIES AND SEASONS. 
OBSERVATIONS ON SQUARES. 
This series of observations was made to determine, if possible, what — 
influence different localities and seasons might have upon prolifera- — 
tion in the same variety of cotton. While similar data have been 
secured for a number of varieties, the exhibit following is restricted — 
to the two varieties on which the largest number of observations — 
was made, as the conclusions which may be drawn therefrom are ~ 
consequently most reliable. In the case of King cotton, different 
seasons as well as localities are represented, while with Shine, different — 
localities are represented at approximately the same time. In com-_ 
pilmg this table, both feeding and egg punctures have been included. — 
It has seemed desirable also to present the figures showing the effect ~ 
which the proliferation has had upon the weevil stages found,
