FEDERAL INSPECTION. 



As agents and collaborators of the Federal Horticultural 

 Board, we are greatly assisted in the inspection of foreign im- 

 portations. The enforced regulation of requiring permits for 

 all foreign plant shipments has been a big factor in preventing 

 the promiscuous lugging in of plants by aid of the ships' crews. 

 Importers of plants with the required permits can, however, 

 ask the assistance of a ship's officer if some rare or tender plant 

 requires care on the ocean trip. 



A decrease is noted in the shipments of plants by parcels post 

 from foreign countries, and this is partly due to the war as well 

 as to the regulations of the Federal Horticultural Board prohib- 

 iting such shipments by mail. But despite the fact, many people 

 have not as yet become acquainted with this regulation, even 

 though it has been widely published. 



INJURIOUS INSECTS AND PLANT DISEASES. 



During the year the usual number of dangerous insects and 

 plant diseases have been intercepted in course of inspection. The 

 following table shows the number of species and genera found : 



Beetles 17 Genera 20 Species 



Butterflies and Moths 7 '' 7 " 



Ants 7 " 10 



Scale Insects 10 " 15 



Plant Lice 4 " 4 



Various 14 " 17 " 



Among the more important pests destroyed during the year 

 were: 



The Argentine ant, which was discovered on two occasions. 

 Other species of ants which have not as yet gained entrance, as 

 well as species wdiich are already established, have frequently 

 been found in plant shipments. 



A weevil, the larvae of which are very destructive to roots of 

 plants, was taken in the soil about the roots of a potted plant 

 from Japan. 



Bagworms, not as yet known in the Territory, were also found 

 on plants from the Orient. 



Cladosporium citri, a very dangerous fungus disease of citrus 

 fruit, has in numerous instances been discovered on fruit taken 

 from the baggage of passengers from the Orient. 



Respectfully submitted, 



E. M. Ehrhorn, 



Chief Plant Inspector.
