California Monthly News Letter Los Angeles County Horticultural Commission 
Volume 11, No, 4, April 15: A preliminary report of inspections 
completed to date in the annual spring survey of all citro^.i- 
lus mealybug infested citrus orchards of record in Los Angeles 
County indicates Very little change from the seasonal average 
of the past five years. Reports made to' H„ M» Armitage by the

increase in light and medium infestations with a corresponding 
decrease in heavy inf ertations. 
An attempt is being made to eradicate an infestation at the 
Van Nuys School at Van Nuys. The eradication program to date 
has consisted of the removal of 29 trees from six different ares 
in the school grounds. An attempt is also being made to con-

COTTONY- CUSHION SCALE ( icerya purchasi Mask. ) 
South Carolina M. H„ Bruncon (April 11 j: The cottony-cushion scale on rose 
was sent to the department from Estill April 7. 
Georgia "..'. S. Yeomans (April 22): The cottony-cushion scale has been 
. showing up again in the Albany section, Australian ladybeetles 
-ill likely put the scale infestation in bounds. 
Florida E. W„ Berger (March 28): The cottony-cushion scale is abundant 
about Gainesville at this time, about 15 separate infestations 
exist. Numerous infestations are also being reported for other 
parts of the State. While most of these infestations are on 
citrus others are on Pittosporum , roses and other plants. In 
the past month about 100 colonics of the Vedalia, or Australian 
Ladybeetles, have been furnished to growers for the control of 
the cottony -cushion scale, and not an instance is kno-n where 
the beetles have failed to control it. 
It is something of an open question why this scale has in- 
creased so abundantly during the -'inter and e< riy spring, ~hich 
is rather unusual, although there is some increase each year 
during the period- indicated. There has been some indicati : 
that the Vedalia were decimated during the P.st summer and fall 
by some disease, Thich may, of course, be the correct explana- 
tion. On the other hand, our rath r continuous cool th r may 
be responsible for having checked the activities of the Vedalia 
but allowing the scale to increase, 
PURPLE SCALE ( L.oidot:aphes beckii Nevm. )
