INSPECTION OF IMPORTED PLANTS AND PLANT PRODUCTS. 



In spite of the reduction in the number of plants imported into the 

 United States during the past fiscal year as the result of Quarantine 

 37, the total number of different kinds of insects (290 species) inter- 

 cepted exceeds that of any previous fiscal year. This increase in the 

 number of interceptions can probably be explained by the fact that all 

 plants imported under special permit were examined under very 

 favorable conditions by expert inspectors at Washington, D. C. More- 

 over, this material did not arrive in large quantities and it was possi- 

 ble to give each plant a very careful examination. Some of the more 

 important interceptions follow: Gipsy moth egg masses on shipments 

 of nursery stock from France; pink bollworm in shipments from China, 

 Japan, and Mexico; potato tuber moth from Australia, Chile, Costa 

 Rica, and Panama ; the sorrel cutworm from France ; spiny citrus white 

 fly from Cuba ; West Indian fruit fly from Jamaica and Cuba ; injurious 

 avocado weevils from Mexico, Guatemala, and the Canal Zone; apple- 

 seed chalcisfrom Germany : wireworm, injurious to potatoes, from Den- 

 mark; sweet-potato weevil from Bahama, Cuba, and Porto Rico; 

 West Indian sweet-potato weevil from Antigua and Porto Rico, and 

 two other injurious sweet-potato weevils from Hawaii and Jamaica. 

 Numerous other pests were collected, including scale insects, mites, 

 and ants.
