TREATMENT. 
Not knowing the cause a specific rem¬ 
edy cannot be recommended. But inas¬ 
much as the chief harm appears to be due 
to the withertip fungus that follows the 
spotting, the recommendation for dis¬ 
eased groves is to strengthen and build 
up the trees by cultural methods, so that 
this weakening may be counteracted; and 
the withertip fungus thus shut out. 
WHITEFLY RESOLUTIONS. 
Mr. President, Ladies and Gentlemen: 
Prof. Hume—If this is considered by 
you a suitable time at which to do so, 
I should like to introduce a set of reso¬ 
lutions directed to the Secretary of Ag¬ 
riculture, in the interest of whitefly 
control. Many efforts are being set 
forth at this time, looking to the control 
of this menace to our citrus industry, 
and good work is being done in work¬ 
ing out methods by our Experiment 
Station workers and by the Bureau of 
Entomology experts. Much has been 
added to our knowledge of control both 
by fungous enemies and by fumigation 
and these methods properly handled 
will go a long way toward abating the 
nuisance. 
But the fungous enemies do not hold 
control without interruption. Fumiga¬ 
tion in some sections is not practicable 
and besides there are localities where 
re-investation would be impossible to 
guard against. 
Now, in this connection, I believe 
there is another method of control 
which deserves careful investigation. 
The native home of the whitefly is said 
to be in China, and there is no reason 
to doubt but that it is there, held in 
check by natural enemies, the most im¬ 
portant of which are doubtless insects. 
These we should have and since the na¬ 
tive home is known, the task of secur¬ 
ing the insect foes should not be a dif¬ 
ficult one. What is needed is the serv¬ 
ice of one or two expert men acquaint¬ 
ed with insects, and having a knowl¬ 
edge of the whitefly. The introduction 
of efficient insect enemies would be of 
immense importance not only to our 
state but to California and all other 
citrus districts of the country as well. 
Therefore be it resolved that we ap¬ 
preciate the work which is now being 
done looking to the control of the 
whitefly in this state, by the Bureau of 
Entomology, and the Florida Experi¬ 
ment Station. We express our approv¬ 
al of these lines of investigation which 
have already resulted in much good to 
the citrus industry both in this state 
and elsewhere in the United States 
where Citrus fruits are grown. 
Resolved that in furthering this con¬ 
trol work we believe the native home of 
the whitefly should be thoroughly in¬ 
spected to secure the natural enemies 
of the insect. 
Resolved that we earnestly petition 
the Secretary of Agriculture and the 
Bureau of Entomology or other divi-
