Bishop, llu' State Quarantine (iii;ii(li;iii ol" Orange ('oimly, California, 

 for determination of the Aleyrodes infcstinjjj its foliage and for final 

 destruction. There were 108 leaves on this gardenia plant. Twentj'- 

 nine leaves taken at random were found by actual count to l)e carrying 

 1,282 larva? of Dialeurodcs cilri, an average of 4-t to the leaf. This 

 plant infested with these citrus white flies was shipped to and delivered 

 at a point in the very heart of California's citrus industry. The con- 

 signee is the owner of an orange grove, and the plant, had it not been 

 lor the present postal regulations and the diligence of the horticultui-al 

 inspectors, would in all probability have been planted in the consignee's 

 yard imnu^diately adjoining the orange grove. It would be superfluous 

 to connncnt on Mr. Bislioi)'s terse statement: "I am wondering what 

 would have ultimately happened had the plant been set out in the 

 yard." The citrus white fly is a winged insect; the city of Orange 

 is contiguous to many square miles planted to citrus trees, and seriously 

 considering all the potential factors of the situation the county of 

 Orange was remunerated in this instance for all the money it has 

 expended in nmintaining an inspection of imports of plant products 

 seeking an entrance into its territory.
