Scale Insect (M>/fila.'ipis ntricola, Packanl) on Orange 



Trees in Monte Video. 



Dr. E. S. ^liller, IJ.X., sent from Monte Video a scale insect 

 affecting the oninge trees there and asking for information as to 

 destroying it. This scale i>roved to be Miftila-^pU citricohi, Packanl. 

 It occui-s in the United States, West Indies, China, I'razil, Soutlu'rn 

 Europe, Ceylon, Fiji, etc. It has been recently introduced into South 

 Africa. Fruit from Southern Europe, Canary antl Madeini is usually 

 infested. 



Its food plants are all citrus fruits and probably all llosace;e. In 

 Jamaica, Cockerell rec(»rds it on the Murniya. Its t)riginal home was 

 probably the West Indies or S(juth America. It occui-s ou leaf, fruit, 

 stems and twigs. 



This scale is about l^{\\ of an inch long, and is about three lime.s 

 a.s long as it is wide, and like the Apple Mu.^^.sel sc4de in outline, the 

 anterior end being narrow and the posterior broad and rounded, the 

 whole scale somewhat curved. 



The colour is variable, some are dull puiplish, othei"s almost 

 brown. Beneath the .scale is white; this lower white portion coming 

 away with the scale retains the in.sect or eggs within. 



The male scale is almost stmight and ^',,th of an inch long. 



The eggs, which vary from twenly-tive to seventy under each 

 scale, are white. All the siwcimens examined from Monte Video had 

 eggs within them.
