VIRUS DISEASES 
No practicable means of detecting the presence of virus diseases in most imported 
plant material is known, but plants or plant parts with characteristic symptoms 
of some virus trouble are offered for entry sometimes. Mosaic was found on leeks 
from Germany and on peppers and squashes from Mexico, and 51 interceptions 
of mosaic were made on vegetables from Cuba. A number of specimens of 
spotted wilt were intercepted in shipments of tomatoes from Mexico. 
NEMATODE INTERCEPTIONS 
Nematode interceptions included Aphelenchoides demani on Convallaria from 
Netherlands; A. fragariae on Begonia from Yugoslavia, Convallaria from Germany 
and Netherlands, and Iris from Netherlands; A. hodsoni on Narcissus from 
Europe; A. huntii on Zingiber from Peru; A. parietinus on various hosts from 
Azores, Bermuda, Ceylon, China, Denmark, Dominican Republic, England, 
Germany, Japan, Netherlands, Paraguay, and Portugal; A. tenuicaudatus on 
Dioscorea from Jamaica; Aphelenchus avenae on various hosts from Cuba, Egypt, 
England, France, Italy, Morocco, and Netherlands; Cephalobus persegnis on various 
plants from Bermuda, England, Germany, and Netherlands; Ditylenchus dipsaci 
in various hosts from Belgium, England, France, Germany, and Netherlands, and 
an interception in garlic from Straits Settlements which presumably originated 
elsewhere as D. dispaci does not occur in the tropics normally; D. intermedins (?) 
on Rhynchostylis from Ceylon ; Heterodera marioni on several unusual hosts for our 
interception files, in material from Canada, Germany, Japan, Mexico, Netherlands, 
South Africa, and Switzerland; Neocephalobus peruensis (description based on this 
material) on Zingiber from Peru; and Rotylenchus bradys on Dioscorea from 
Jamaica. 
COMMON PESTS INTERCEPTED 
Many pests known to occur in this country are intercepted on imported plant 
material. Doubtless some of these represent strains not found here, but tests 
to ascertain such status are not practicable. While many of the interceptions 
of some of these common pests are not reported, enough are recorded to give a 
fairly representative sample of them. In this summary of these records the 
numbers following the names of the organisms indicate the number of countries 
of origin from which the pest was intercepted and the total number of intercep- 
tions recorded.
