GYPSY MOTH AND BROWN-TAIL MOTH QI AKANTINE ENFORCEMENT 
CERTIFICATION OF QUARANTINED PRODUCTS 
Enforcement of the gypsy moth quarantine regulations continued as hereto- 
fore, with 21 district inspectors assigned to as many districts. There was a 
C()nii)lete shift in the territories assigned to each inspector, so that the men 
might obtain experience in new sections and in a variety of quarantine activity. 
There were no developments requiring revision of existing <inaranlinc regu- 
lations. In an administrative order issued March 2, 1937. a few items were 
added to the list of articles exenq)t(>(l from the regulations as iioncarriers of 
moth infestation. 
Twenty-three temporary inspectors were employed in the inspection of Christ- 
mas trees and other evergreen material used for Christmas decorations. I>ur- 
ing the 193G .season only one gyi)sy moth egg cluster was found on Christmas 
trees presented for insix^ction and certitication. The discovery was made on a 
balsam fir at a nursery in southern Vermont. An S.">-percent incr-^^a.se -vas 
noted in the number of Christmas trees inspected and certified for shipment 
from the lightly infested gypsy moth area. In Maine approximately m.OOO 
more trees were inspected and certilied this year than in 15)3'). All but '> 
percent were balsam firs, the demand for which has been increasing yearly. In 
Vermont, where approximately 7') percent of all evergreens are spruces, the 
demand for balsam fir exceeded the supply. Inspection of spruce boughs 
extended from the middle of October to early in Decem])er in Massachusetts 
and southern Vermont, 
New England experienced the heaviest fall demand for nursery stock in- 
several seasons. During October and part of November the assignment of addi- 
tional inspectors was re(niired in practically all the infested States. Seo\iting 
of nurseries that shipped under joint Japanese beetle and gypsy moth certifi- 
cates was completed in November. No gyp.sy moth egg clusters were found in 
or in the vicinity of any such nurseries. 
Throughout the year inspectors destroyed 1,257 egg clusters. 235 larvae, and 
136 pupae, all taken from material destined to nonregulated points. Inspection 
of a 12-car shipment of lumber in November netted 12.") egg clusters.

tive quarantined products certified during the year,
