status of control. Whether plant diseases are more destructive in the 
South than in the North is a question which can best be answered by the 
phytopathologist. 
As our experience with quarantines has been limited to Florida w r e can 
discuss them only from the standpoint of Florida’s experience, but it 
seems safe to conclude that what applies in the case of Florida will also 
apply, in more or less degree, to all southern states. 
The plant quarantine work in Florida was commenced in 1915 and 
since its inception has been conducted in close cooperation with the 
Federal Horticultural Board. Inspectors of the State Plant Board of 
Florida, engaged in quarantine work, hold appointments as collaborators 
of the Federal Horticultural Board and enforce the quarantine regula¬ 
tions of the latter Board as well as of the State Board. 
In the case of some pests, the federal regulation is considered as amply 
sufficient but in other cases the federal regulations are supplemented by 
state regulations which, it is thought, add to the protection afforded to 
Florida alone. In still other instances the state maintains quarantines 
which are of importance to Florida only and which deal with insects or 
diseases of which the federal regulations do not take cognizance. 
While the quarantines are intended to guard against the introduction 
of a very large number of foreign pests, the following may be mentioned 
as the most important: 
The Mediterranean fruit fly (Ceratitis capitata (Wied.)) from Bermuda, 
Hawaii and other countries, the West Indian fruit fly ( Anastrepha 
fraterculus (Wied.)) from the West Indies, Argentine, Brazil, Chili and 
other Central and South American countries, the Mexican orange 
maggot (. Anastrepha ludens (Loew)) from Mexico, the pink bollworm 
(.Pectinophcra gossypiella (Saund.)) and the black fly ( Aleurocanthus 
woglumi Ashby). 
The amount of inspection work performed at the Florida ports from 
Dec. 13, 1915 to April 30, 1922, is summarized in the following table:

*Prior to August 1, 1918, horticultural material inspected was reported by “shipments.” A 
‘“shipment” might contain any number of packages. Subsequent to the above date reports were made 
of the number of packages or containers.
