Insects Injurious to the Mango. 19 
THE MANGO SCALE. 
A scale insect which is to be found on the limbs and trunk of the 
trees is the mango scale’ (fig. 10). It masses in cracks or under loose 
bark, and resembles minute seeds or eggs. When numerous it also 
appears somewhat like the chaff scale on the branches and trunk of 
the tree. It is not very destructive. The female scale is from one- 
fiftieth to one twenty-fifth inch in length. It is narrow and flattened 
at the tip. The scale is convex and has a loosely adhering, saclike, 
waxy white covering. It does not infest plants other than the mango,

and has been found at Homestead, Larkin. Palm Beach, Little River, 
and Miami. It is a pest of the mango in India, and was apparently 
introduced into Florida from that country. 
CONTROL. 
The oil emulsions, as used against the soft scales during the winter, 
have been found most satisfactory for this species, the spray being 
directed toward the branches and trunk of the tree with sufficient 
pressure for penetration, preferably 250 pounds.
