hosts from Belgium, Danzig, Denmark, England (including Iris histrioides major 
new host), France, Germany, Italy (?), Morocco (new locality), Netherlands, New 
Brunswick, Norway, Union of Soviet Socialist Republics (new locality), Scotland, 
and Sweden; A. intermedia in ginger from China; A. pratensis from Argentina, 
Germany, and Japan; A. robusta in Hosta sp. from Italy; (Aphelenchoides 
bicaudatus in Eryngium foetid um offered for export from Puerto Rico to the 
mainland and hence interception not shown in list); A. parieiinus from Brazil, 
China, Danzig, England, France, Germany, Italy, Japan, Netherlands, Norway, 
Scotland, Sweden, and Wales; A. tenuicaudatus in ginger from China and in yam 
from Japan; Aphelenchoides sp. from Belgium, Japan, and Lithuania; Aphelenchus 
avenae from England, Germany, Hungary, Italy, Japan (in Puerto Rico in material 
offered for export to mainland), and Sweden; \Dorylaimus n. sp. in Hosta sp. from 
Italy, not a plant parasite and hence not in list), Hoplolaimus bradys in yam from 
Puerto Rico; Paraphelenchus amblyurus in yam from Japan; P. maupasi in hya- 
cinth from the Netherlands. 
The interceptions of root-knot nematode (Heterodera marioni) are not shown in 
the main list but included the following new hosts: Hydrangea opuloides from 
Azores; Antennaria dioica iomentosa, Convolvulus limatus, Gentiana acaulis, 
Geum hybridum, Lamium orvala alba, and Raphithamnus cyanocarpus from England; 
Epiphyllum sp., Rehmannia bergi, and Iris laevigata from Japan; Helenium pumi- 
lum from the Netherlands; Spathoglottis parsoni from the Philippines. 
For a number of diseases the causal organism could be determined to genus 
only because it was an undescribed species or appeared to be so because it did not 
agree with the description of any species reported as occurring on the host or 
related plants. Among these were Ascochlya sp. on Fatsia japonica from Japan; 
Ceratostomella sp. on ginger from China; Cylindrosporium sp. on Aspidistra lurida 
from Japan; Glososporium sp. on F. japonica from Japan; Leptothyrium sp. on 
Paeonia suffruticosa from Japan; Linochora sp. on Ficus sp. from Guatemala; 
Mycosphaerella sp. on Wisteria multijuga from Japan; Par aphelenchus sp. (later 
described as P. amblyurus) in yam from Japan; Pestalozzia sp. on F. japonica 
from Japan; Phoma sp. on Aucuba japonica from Japan; Phomatospora sp. on 
F. japonica from Japan; Phomopsis sp. on Eriobotrya japonica from Italy and on 
Sciadopilys verticillata from Japan; Phyllosticta sp. on Codiaeum sp. from South 
Africa; Sclerotium, n. sp., on Narcissus sp. from the Netherlands; and Selenophoma 
sp. on Dendrobium ashworthiae from England. 
AIRCRAFT INTERCEPTIONS 
Two hundred and four interceptions of insects w T ere made. Among these were 
the following: Anastrepha sp. (Trypetidae) in nispero from Trinidad; Aspidiotus 
cocotiphagus (Coccidae) on coconut from the Bahamas; Coccus viridis (Coccidae) 
on Cape-jasmine, and Laivsonia alba from Cuba; Frankliniella cubensis (thrips) on 
Rosa sp. from Cuba; F. insularis on Cape-jasmine from Cuba; Pseudischnaspis 
alienus (Coccidae) on orchid from the Canal Zone; and Targionia hartii (Coccidae) 
on yam from Cuba. 
Four plant-disease interceptions were made: Cephaleuros virescens (alga) on an 
orchid from Costa Rica; Colletotrichum sp. on coconut from the Bahamas (2) and 
on an orchid from Brazil. Scale insects on an orchid from Costa Rica were 
infected with Aschersonia cubensis and scale insects on cherimoya from Cuba 
with Cephalosporium lecanii. 
COMMON PESTS INTERCEPTED 
In addition to the pests named in the itemized list which makes up the body of 
this report, there were numerous interceptions of cosmopolitan pests that are 
more or less prevalent in this country. While it is true that many of these inter- 
ceptions may represent forms or strains not yet introduced and potentially 
dangerous, it is not believed essential to the purposes of this list to include the 
details of their interception. They are, however, included in brief form in this 
preliminary text. Following each pest name are two figures in parenthesis and 
separated by a dash, the first indicating the number of countries from which the 
pest was intercepted and the second the total number of interceptions. The 
customary data regarding this material are on file and available to anyone 
interested.
