THE NATIONAL NURSERYMAN.

It seems that both the spraying operations and the unfavor one-brooded, however, and does not multiply with near 
able winter have been responsible for this condition of affairs, the rapidity that San Jose scale does, it is very possible that 
We are forced now to conclude that there is only the remotest the Asiatic Lady Bug might in time control this pest entirely, 
possible chance of this beneficial insect ever becoming abund- The plum Pulvinaria need not offer any terrors to the fruit 
ant enough to control the San Jose scale in the South, although under 
favorable conditions it might become abundant enough to form a useful 
natural check to the scale in localities where it is not controlled by 
spraying. 
The fruit grower is confronted by a peculiar problem when he tries to 
utilize this lady bug. If he allows the orchard to remain unsprayed in 
order that the scale may increase and form favorable conditions for 
the increase of the lady bugs, it is almost certain that the scale will 
have destroyed his orchard before the lady bugs have become numerous 
enough to check the scale; on the other hand if he sprays to control the 
scale, he destroys the lady bugs. 
In spite of these discouraging features, when we consider the numbers 
attained by this beneficial insect in 1903, it might become a valuable 
adjunct in case we should have a succession of years of favorable to it. Fig. 13.

orable conditions will 
be greatly increased. 
We have therefore 
taken what remaining 
specimens we could ob¬ 
tain and have trans¬ 
ferred them to two or¬ 
chards, far to the south¬ 
ward, in the hopes that 
under a warmer winter 
they will again reach 
the point of abundanec 
that will enable us to 
distribute them all over 
Georgia. One of the 
places where we are try¬ 
ing to rear them is in 
extreme south Georgia, 
where spraying will not 
in the least interfere with them and where scale is everywhere 
abundant. The other orchard where we are attempting to 
propogate them is still further south, on the peninsula of 
Florida. 
An interesting observation was made this summer upon 
the feeding habits of this species. In a plum orchard which 
was quite badly 
infested with a 
cottony scale, 
Pulvinaria amy- 
gdali, we found 
the lady bugs 
feeding readily 
upon the egg 
masses of this 
insect. This Pul¬ 
vinaria has at 
times become a 
very severe pest 
in orchards of 
growers as it passes the 
winter partially grown 
upon the twigs and 
trunk of the trees and 
will without doubt yield 
easily to any of the lime 
and sulphur washes. 
BLACK-BEN DAVIS! 
One of the most in¬ 
teresting exhibits to the 
average apple grower to 
be seen in the Horticul¬ 
tural Building at the 
World’s Fair was three 
plates of apples shown 
in the Iowa Exhibit: 
One plate each of Ben 
Davis, Gano and Black- 
Ben Davis. 
For several years it has been claimed by some, that the 
Black-Ben and Gano are identical, though Stark Bros., the 
introducers, have strenuously contended that they are en¬ 
tirely distinct and that Black-Ben Davis is the best apple; 
and this contention seems now fully sustained by the facts. 
Certainly no well posted and discerning horticulturist could 
look upon the three varieties as exhibited by Iowa and claim 
that any two are identical. In addition to this exhibit, some 
splendid specimens of Black-Ben Davis were shown in the 
exhibits of Arkansas, Oregon, New Mexico, Washington, 
Colorado, Oklahoma, 
California and others. 
In every case the dis¬ 
tinctiveness of Black- 
Ben Davis compared 
with Gano was clearly 
apparent, and among 
the best posted horticul¬ 
turists it is now a con¬ 
ceded fact that Black- 
Ben Davis is the best 
apple of the three.
