ANNOUNCEMENT RELATING TO SWEETPOTATO QUARANTINE 
(DOMESTIC) (NO. 30) 
SWEETPOTATO QUARANTINE (DOMESTIC) 
Notice of Quarantine No. 30 (Revised) 
introductory note 
Since the promulgation of the Sweetpotato and Yam Quarantine No. 30, 
effective January 1, 191S, this measure has not been changed. In the inter- 
vening period, however, many observations in Puerto Rico have disclosed no 
definite evidence that the yam (Dioscorea spp.) is subject to attack in that 
island by the insects Cylas formicarius Fab. and Euscepes batatae Waterh., on 
account of which this quarantine was imposed, and it is believed that yams 
can now be safely allowed entry from both Puerto Rico and Hawaii if ship- 
ment is made under inspection and certification by the plant quarantine in- 
spectors stationed in these Territories. 
The present revision of Notice of Quarantine No. 30, therefore, removes the 
prohibition against the movement of yams from Puerto Rico and Hawaii, and 
the yams thus released will fall automatically under the restrictions otherwise 
governing the movement of fruits and vegetables from these islands. 
In this revision the commercial movement of sweetpotatoes is still pro- 
hibited from Hawaii and Puerto Rico. Another injurious insect, the sweet- 
potato stem borer (Omphisa anastomosalis Guen.), has been specifically listed 
as a reason for quarantine action, in addition to the sweetpotato scarabee 
{Euscepes batatae Waterh.).
