JAPANESE BEETLE QUARANTINE REGULATIONS AMENDED 
[Press notice] 
June 24, 1939. 
An amendment to the Japanese beetle quarantine regulations, effective July 1, 
was announced by the Secretary of Agriculture today under which Rochester 
and Brighton, N. Y., are added as isolated, regulated areas, and all of Cuyahoga 
County, Ohio, is brought under regulation. This changes the status of Cleveland 
so that certification is required for all restricted commodities moved from that 
city to nonregulated territory. 
Another change included in this amendment is the omission of regulated parts 
of Steuben County, N. Y., other than the town of Hornellsville, from the isolated 
areas. The exemption of certain types of sand and clay has been clarified and 
the requirements for certification of nursery and ornamental stock received by 
establishments within the regulated areas have been modified. 
MODIFICATIONS OF JAPANESE BEETLE QUARANTINE REGULATIONS 
INTRODUCTORY NOTE 
The following amendment to the Japanese beetle quarantine regulations adds 
to the regulated area four townships in Cuyahoga County, Ohio, bringing the 
entire county within the area. This extension parallels action already taken 
by the Ohio Department of Agriculture to relieve a traffic situation encountered 
in the operation of vehicular inspection stations on westbound highways from 
the Cleveland area. With the extension of the continuous regulated area to 
include that city, certification is required for all restricted commodities moving 
from Cleveland to nonregulated territory. Rochester and Brighton, N. Y., are 
now included as outlying regulated areas subject to the same restrictions as 
apply to similar isolated points. 
Another change included in this amendment is the omission of regulated 
portions of Steuben County, N. Y., other than the town of Hornellsville, from 
the isolated areas to which the movement of certain quarantined articles was 
heretofore required to be certified. 
A section of regulation 7 exempting from the certification requirements certain 
types of sand and clay is reworded to clarify the requirement. 
Requirements are modified for the certification of nursery and ornamental 
stock received by nurseries and greenhouses within the regulated area, both as 
to the infested and noninfested nurseries and greenhouses.

Chief, Bureau of Entomology and Plant Quarantine.
