Smithsonian Institution. Snail identifications are made by personnel of 

 the Plant Quarantine Division and the Division of Mollusks of the Smith- 

 sonian Institution. Disease, nematode, and host identifications are 

 made by personnel of the Plant Quarantine Division and the Plant Sci- 

 ence Research Division. 



Scientific names of insects and diseases are reviewed by special- 

 ists of the Plant Quarantine Division who assist in producing the list. 

 Nematode names are checked in Nematology Investigations and host 

 names in the New Crops Research Branch. The common names given 

 for hosts are usually those shown in Standardized Plant Names. Every 

 effort is made to conform to the International Rules of Nomenclature. 



Family names of insects, mites, and snails are given in the tabu- 

 lation and orders are shown in the host list. 



NOTES ON PESTS INTERCEPTED 



The total number of interceptions submitted during the fiscal year 

 1969 was 41,279. Of those identified during the fiscal year, 11,658 

 were considered of enough significance to be tabulated, as compared 

 with 11, 346 the previous year. This does not include the non-economic 

 or the incompletely determined organisms which were not added to 

 the figures in the summary.

the spread of 



PLANT 



PESTS 



PESTINA was developed by the U.S. 

 Department of Agriculture and sym- 

 bolizes the need for the traveling public 

 to comply with agricultural plant quar- 

 antine laws, thus helping to prevent the 

 spread of agriculture pests. Suchpests 

 are capable of causing millions of dol- 

 lars in crop losses and often are trans - 

 ported in foreign fruits, plants, and 

 meats. PESTINA is portrayed as a 

 public-spirited figure, helping to re- 

 mind travelers to leave behind foreign 

 fruits, vegetables, and plants, unless 

 such items have USDA clearance.
