While these were not entomologists, 
nevertheless the work of Dr. H. J. 
Webber pertained in a large part to the 
control of the whitefly. This was be¬ 
fore the great freeze of 1894-5. Be¬ 
sides valuable experiments on spraying 
for the whitefly he discovered two of 
its principal fungus enemies, namely, 
the red (Aschersonia aleyrodes ) and 
the brown (Aegerita webberii), and 
recommended spreading them by 
means of small trees planted close to 
grove trees. 
In July, 1906, the Bureau of Ento¬ 
mology, U. S. Department of Agricul¬ 
ture, established the “Whitefly Lab¬ 
oratory” at Orlando, Fla. This was in 
response to a call for help from the 
Florida citrus growers. At first, un¬ 
der the direction of Dr. A. W. Morrill, 
the work has since been carried on by 
Dr. E. A. Back and Mr. W. W. Yoth- 
crs, the latter of whom is still with us 
and will speak to you today. 
In this connection, I must not omit 
reference to the visit of Mr. Woglum 
to India, the native home of the white¬ 
winged species of the citrus whitefly 
(A. citri .) Mr. Woglum left this coun¬ 
try last July and is visiting India and 
adjacent countries in search of insect 
and fungus parasites of this insect. 
Since Mr. Woglum is still abroad and 
Lis final report has not been submitted, 
nothing definite can be stated except 
that he has found a ladybird feeding on 
the whitefly and has sent specimens of 
the well known brown fungus of this 
pest from India. 
While this paper has been mainly an 
enumeration of the workers in Ento¬ 
mology, a short resume on the whitefly 
will be introduced here. This pest 
(A. citri ) was observed and studied in 
the Orangeries at Washington about 
1878. It existed at Gainesville, Fla., 
about the same time. It appeared at 
Panasofkee in 1876. Alachua and Ma¬ 
rion counties were perhaps the first to 
have the whitefly. 
The cloudy-winged species (A. nubi- 
fera) was also a pest in Mississippi, 
North Carolina and Louisiana as early as 
1889 and 1890, respectively, and is be¬ 
lieved by some to have been introduced 
into Louisiana in 1885 on trees brought 
to the New Orleans Exposition. The 
cloudy-winged species also existed in 
Florida before 1895 at Crescent City. 
It is therefore practically certain that 
there have been at least two separate 
introductions of the whitefly. This con¬ 
clusion is based upon the fact that both 
species occurred separately at such 
wide distances as Louisiana, Missis¬ 
sippi and North Carolina on the one 
hand, and Florida on the other. Then, 
also, the cloudy-winged species has 
never been reported from the Orange¬ 
ries at Washington. Besides the possi¬ 
bility of the white-winged species hav¬ 
ing been sent out from the Orangeries 
at Washington, it is also probable 
that separate introductions were made 
on trees received directly into Florida 
from the East. 
RESUME. 
What is the benefit to the grower of 
this array of Entomological talent, 
perhaps sometimes not talent, covering 
about fifty years ? The answer: There is 
at present a mass of literature, including
