the avocado weevil. It does not injure the flesh of the fruit especially. 



Mr. Hart: Referring again to the black scale, I v^as out at Mr. 

 Walker's place in Hollywood, where there are a number of large trees 

 that have been growing for a number of years. There is a lemon orchard 

 adjoining the avocado plantings. This lemon orchard was black with black 

 scale and in a very bad condition, but the avocado trees did not have any 

 scale so far as I could see, showing that the black scale prefers the lemon 

 to the avocado. My seedling oranges accumulate a lot of black scale every 

 year. Avocados alongside have a few, but apparently the scale does not 

 thrive and is scattered. I think it is safe to say that it much prefers the 

 citrus to the avocado. I don't believe this scale will be serious on the 

 avocado at the present time. 



Mr. Spinks: I have had avocados among orange trees. The orange 

 trees have more or less black scale and also some other scale pests. I 

 find that if the avocados are crowded up against the citrus covered with 

 scale, they are apt to get some scale but not many. I have seen a brown 

 scale cover the trees pretty well, but I have succeeded in getting rid of 

 it by spraying. Strange to say, it did not communicate itself to any 

 other tree.
