WHITE TOP CONTROL PROTECT SUCCESSFUL, 
; 
Tn November, 1918, an inspection was made fas T. HE. Snyder of the White Top Pur- ‘ 
hase Area, in Virginia and Tennesse ich showed that the treatment of 1,612 for 
it 617%) out of a total of 2,612 pines infest od by the southern pine beetle :| 
ndroctonus frontalis Zimm.) served to reduce the infestation on the treated | 
14 adjacent areas 96% below the amount of infestation found at the time control } 
sek was: Started. Only 102 infested trees were located, mostly scattering or in 
ub clumps, and these were not near where the control work was carried on in March, 
by the Forest Service under recommendations of the Bureau. 
Tu three localities, however, infested trees were found in large clumps and 
Rac, On the recommendation of Dr. A, D. Hopkins, the Forest Service left untreated, 
i Object being to secure an additional test of the influence of control work on We 
Be CoOitinuation of the reduction of the infestation during the next year or two and, 
Pecially, as an experimental demonstration with D, frontalis. The area was 
tched by thé local officials for new infestation during the summer of 1916. 
A letter has just been received from the Forester stating that the local officer 
charge of the White Top Area reports that general observations over the whole area 
réful inspection of the principal centers of former infestation, made in Oc- 
, 1916, fail to show any infestation.****** He believes that the control meas-' 
Pes carriéd out may be credited with highly satisfactory results. 
_ his is 4 convincing demonstration of the economy and efficiency of the percent- 
© principle of controlling this most destructive insect enemy of the pine timber 
| the Southern States.
