THE BLACK PARLATORIA 11 



Parlatoria zizyphus (Lucas) 



(Coccus eizyphus Lucas) 



(Fig. 170) 



Description.— The scales of the 

 males and females are distinctly 

 black with a colorless portion at the 



posterior end. In the male scales the black area is nearly circular and 



very small, while in the 



females it is elongated and 



slightly over 1-25 inch 



long. They are massed 



together in dense colonies 



and are easily recognized 



at once by the black color. 

 Distribution. — This 



scale does not at present 



occur in California. It is 



a common serious citrus 



pest in the Philippine 



Islands, southern Europe, 



Hawaii and many other 



tropical and subtropical 



countries, and is often 



taken in quarantine. 



Strict measures should be 



maintained against its 



becoming established 



here. 



Food Plants. — The 

 citron, grapefruit, lemon, 

 lime, orange and Zizy- 

 phus are attacked. 



Control. — Control 



measures are the same as Fig. 170. — The black Parlatoria, Parlatoria zizy- 



fnr iha olia-PP onoln phus Lucas, on orange leaf. Enlarged three times.

 quarantine. It is light-gray in color and also a citrus pest, but not as serious as the 

 above.
