COMMON PESTS INTERCEPTED 
The following summaries of common insects and plant diseases may include 
forms or strains not yet introduced and hence potentially dangerous, but we have 
no practicable means for determining that point. The two sets of figures in 
parentheses following each pest name indicate the number of countries from 
which the pest was intercepted and the total number of interceptions.
