j Spraying Apple Trees. 53
 » The scale differs from _all others seen in Kentucky in its ca-
I pacity for increase. The young are born alive and an infested I
I I tree becomes in a short time thickly covered with the scales, out I
 _ to the tips of the branches. Other similar scales remain pretty ,I
. generally about the main branches and never cover the bark so  
completely. It is this power of increase that renders this small  
scale so formidable to the fruit grower. It is so small that when I .
appearing in small numbers, it is likely to be overlooked, and if  
 . overlooked for a season, it may gain such headway from its rapid _  
rate of increase that remedial treatment becomes difficult and I
l costly. j
`4 We have not been as much troubled with it in Kentucky as QI
. have fruit growers in adjoining states. Our inspection law was II
I ` enacted soon after attention was drawn to the insect in the Eastern ,  
' States, and so far as our nurseries are concerned, we have been kept 1  
A practically free from it. Along our northern borders, however, in  
* orchards, it has been permitted in some cases to multiply without  II
5 p check, and it is important, in order to prevent its spreading over  I
E all our fruit-growing sections to amend our inspection law so as  
> _i to check this spread of the pest outside of nurseries. .  
S The scale has been found to be badly infested in some parts  
of the State with a small insect parasite. This parasite is a mem—  
.t · · ber of a genus known to entomologists from its destruction of ,  
=r · scale insects, and is quite capable, should it become generally dis-  
I tributed in the State, of keeping the San Jose scale completely  
I in check.  'I
I Scales received from Mr. Lucien Beckner, of Clark County,  
I Kentucky, September 26, 1906, were very many of them de—  
SHO}/erl by the parasite, which was emerging and continued to fz
B'   emerge for some time after the material was received. The insect  
at   is so minute that it can scarcely be seen with the unaided eye. Q
