OLEANDER SCALE. (Figure No. 6.) 

 Aspidiotus Nerii (Bouche). 



Figure No. 6. 

 i.— Leaves and twigs infested with the scale. 1 a.— The male insect greatly magnified ; 

 color, yellow and brown. 1 b. — Scale of male very enlarged ; color, white. 1 c. — Scale of 

 female highly magnified; color, whitish or gray. 



The female is of a whitish color and nearly circular; measures one line 

 in diameter; exuviae, or cast skin, yellowish and near the center. Male 

 scale white and not as circular as that of the female; egg, light yellow; 

 larva, yellowish white; length, one eighty-fifth of an inch. Female, light 

 yellow with darker blotches; abdominal segments appear as a pointed pro- 

 jection at one end of the circle. Male insect, body yellowish with dark 

 markings. 



This scale affects a great many trees, especially evergreens. Lemon trees 

 become badly affected by it and the fruit is somtimes completely covered 

 with it. Among others the olive is also subject to it, and we have seen trees 

 badly infested with the insect. The fruit of the olive when infested does 

 not mature well, and wherever a scale is found a green blotch shows its 

 appearance. As this is the only scale affecting the olive in the dry interior 

 valleys, it is important that it should be guarded against.

The following description is taken from the report of the late Mr. M. 

 Cooke to the Board (see report of 1881).
