Insects Injurious to the Mango. 17 
CHARACTER OF INJURY. 
Injury resulting from the feed- 
ing of this scale is of the same 
nature as that from the mango 
shield scale. The seasonal history 
of this species does not differ ma- 
terially from that of the mango 
shield scale, approximately three 
generations in the year being pro- 
duced. The plants which this scale 
infests have been found to be the 
coconut palm, fishtail palm, and 
mango. 
CONTROL. 
The oil-emulsion sprays, as rec- 
ommended against the mango 
shield scale, are advised in the con- 
trol of this pest. 
THE FLORIDA RED SCALE. 
A scale found to infest the mango 
at times is the Florida red scale ° 
(fig. 9). Occasionally it may be 
found infesting both the leaves 
and fruit of the mango. The scale 
is dark reddish-brown in color, 
with a conspicuous light-brown 
center, almost circular in outline, 
and is about one-twelfth of an inch 
in diameter when full grown. 
Besides the mango, this scale in- 
fests citrus, the royal coconut, and 
many other palms, camphor, mag- 
nolia, oleander, roses, myrtle, and 
many other plants. 
CHARACTER OF INJURY. 
This species does not produce 
honeydew, and hence the sooty- 
mold fungus is not found where it 
is present on the trees. Like the 
other scales, its principal injury is 
‘aused through the extraction of 
the sap from the foliage and fruit.

leaf.
