the main issue is — will the interests of the state be served best by 

 imported nursery stock plus foreign pests or by no imported stock 

 and no pests? 



Since writing the above, two additional foreign species established 

 in New Jersey have been identified. One of these is Eucactophagus 

 graphipterus Champion, a weevil whose larva lives in soft bulbed 

 orchids and is capable of doing considerable damage to such greenhouse 

 stock. This came to us in orchid stock from Central America or the 

 U. S. of Colombia. The other is a Tingitid from Japan, namely Ste- 

 phanitis azalece Horv., which did considerable damage to hardy azaleas 

 in various parts of the state during the past season, and which appears 

 to be firmly entrenched. This species was introduced with azaleas 

 imported directy from Japan and escaped detection until it had 

 established itself over the entire state. 



In closing I wish to express my indebtedness to the various special- 

 ists in the U. S. Bureau of Entomology, who through the courtesy 

 of Dr. L. 0. Howard identified many of the species mentioned. 



IMPORTANT FOREIGN INSECT PESTS COLLECTED ON 

 IMPORTED NURSERY STOCK IN 19 15 



By E. R. Sasscer 



The condition of nursery stock offered for entry has unquestionably 

 shown a marked improvement since the passage of the Plant Quaran- 

 tine Act in 1912. This condition cannot be attributed to a falling off 

 of importations during the present year, for, as shown in the accom- 

 panying table, the European exportations for 1915 exceed those of 

 1913 and 1914.

In spite of the increased European importations and the unsettled 

 condition of the countries which export in bulk to the United States, 

 nursery stock, for the most part, has been comparatively free from 

 injurious insects during the current year. It is obvious, therefore,
