SERVICE AND REGULATORY ANNOUNCEMENTS 6 
COMMON PESTS INTERCEPTED 
Many pests and diseases known to occur in this country or found frequently on 
certain* material offered for entry are recorded on tally sheets instead of on the 
more complete record forms. While many of the findings of these common forms 
never get recorded at all, enough are recorded to aid in giving a picture of the 
condition of material inspected, from the standpoint of pests present. It '"s 
recognized that foreign strains of some of these common pests and diseases might 
be destructive if established here, but inspectors would have no way of determining 
that point. In the following summary of these pest and disease records the 
numbers following the names of the organisms indicate the number of countries 
from which interceptions were made and the total number of records made 
during the year.
