GREEDY Scate (Aspidiotus rapax, Comstock). 
This scale is found to attack a large variety of fruit-trees, 
plants, and shrubs, and is often noticed infesting the pear, peach, 
plum, apple, and apricot trees. Notwithstanding that this scale is 
usually found thickly covering the whole stem or branches of its 
food plants, it seldom causes any serious damage. 
The scale of the female is nearly circular, or slightly oval, 
yellowish in colour when it covers a living, matured insect, but is 
generally a light grey. The full-grown specimens measure nearly 
one line in diameter, and its form is more convex than the other 
species of Aspidiotus referred to in these pages. 
Remedies—In winter, use Nos. 10, 14, 20, or fumigate with 
No. 18 (see p. 528). 
Natural Enemies—While yet no true parasite of the greedy 
scae has been discovered, yet there are a number of predaceous 
ladybirds in this State which feed upon it, and accomplish a great 
deal in reducing their numbers.
