GARDEN PESTS IN NEW ZEALAND 



The female scale is almost circular (Fig- 7, 7), having a diameter 

 of from one-twenty-fifth of an inch to two-twenty-fifths of an inch, and 

 is rather flat; the male is more oval and of the same size, and in both 

 cases there is a central orange-yellow spot. The eggs are comparatively 

 large,, and hatch soon after being deposited. The insect reaches maturity 

 in from four to six weeks. 



GREEDY SCALE (Aspidiotus rapax). This European insect is now 

 widespread, and in New Zealand is common on apple, pear, quince, and 

 wattle ; it has a wide range of hosts. The adult female scale is convex 

 and of a general grey colour, though sometimes yellowish. The winter 

 is passed in all stages of development. 



HOSE SCALE (Aulacaspis rosce). This is a very common insect,, 

 forming white incrustations on the bark of roses, briar, raspberry, logan- 

 berry, blackberry, and sometimes pear. The adult female (Fig. 7, 8), 

 which is from one-twelfth of an inch to one-eighth of an inch in 

 diameter, is rather thin and flat, circular or oval in outline, but irregular 

 when crowded; the general colour is white or slightly yellowish. The 

 male (Fig. 7, 9) differs, in being elongated and narrow. This insect 

 can withstand severe winters, and is to be controlled by the use of 

 red oil.
