1932] SERVICE AND REGULATORY ANNOUNCEMENTS 81 
The responsibility for preventing the mixing of infested bulbs with bulbs which 
have been treated and are eligible for certification, rests directly on the local 
inspector, and the working out of a general procedure for the maintenance of 
identity of such bulbs under the special conditions existing in different States 
rests jointly on the local inspector and the chief inspector for the State concerned. 
MARKING REQUIREMENTS 
In answering questions as to certification, the provisions of regulation 5 of the 
quarantine should be kept in mind. That regulation reads as follows: 
"(a) Every crate, box, or other container of narcissus bulbs offered for inter- 
state movement by the grower thereof shall have securely attached to it the 
shipping certificate provided for in regulation 3. In the case of a carload ship- 
ment, such ceitificate shall also accompany the waybill, conductor's manifest, 
memorandum, or bill of lading pertaining to the shipment. 
11 (6) Such certification shall remain and continue as a condition of any reship- 
ments of such certified bulbs for interstate movement in original containers. 
"(c) Certified narcissus bulbs taken from crates or other original containers 
for reshipment interstate in smaller lots shall have securely attached to each 
container a tag or label signed by the shipper thereof reading as follows: 'The 
undersigned certifies that the narcissus bulbs contained herein were taken from 
a shipment of narcissus bulbs certified by the Bureau of Plant Quarantine 7 
under Notice of Quarantine No. 62.'" 
A record of the treatment of each lot of bulbs for which permits for interstate 
movement are issued is to be filed in the office of the chief inspector for the State 
concerned. At the end of the inspection season, a report of the field inspection of 
each grower's bulbs is to be combined with a report of the warehouse inspection 
and treatment, on Form 432, and mailed to the Bureau of Plant Quarantine, 
United States Department of Agriculture, Washington, D. C. State inspection 
officials may make provision for such additional detailed reports of spring inspec- 
tion work and of detailed treatment records as their own conditions may make 
necessary or desirable.

FIGURES 
The following figures are sketches of a few of the species of nemas most com- 
monly found in diseased narcissus bulbs. The three species figured to the left — 
Tylenchus dipsaci, Aphelenchoides subtenuis, and A. parietinus — are spear-bearing 
forms and are parasitic. The spear or stylet is used for the puncturing of the plant 
tissue. The three forms figured to the right — Cephalobus elongatus, a Diplogaster 
species, and a Rhabditis species — are considered to be mainly saprophytic. This 
means that they are associated with or follow some other primary disease agent or 
enter a plant only when it is in weakened state (through abnormal climatic condi- 
tions, through imperfect hot-water treatment, etc.), or after a plant has been 
injured. These saprophytic forms may also associate with or follow T. dipsaci 
and the two Aphelenchoides species. The presence of saprophytic nematodes, 
which are without spears and are broader and more active than the parasitic 
species, is to be ignored by inspectors. Special instructions should be secured in 
the case of Aphelenchoides infestations. The eelworms referred to in this circular 
are, except when otherwise stated, those of the species T. dipsaci. 
These figures have been prepared for this circular by the Division of Nema- 
tology of the Bureau of Plant Industry.
