THE CITRUS MEALY BUG 2-Jl 



Two years ago the mealy bug was reported in two orchards in Santa 

 liarbara County, but to date Mr. C. W. Beers, Horticultural Commissioner, 

 informs me tiiat after a close inspection, not a single insect is to be found 

 in these orchards. It does exist, however, in t\e greenhouses and flower 

 gardens in that City, 



A general summary of the present distribution is as follows :

DESTRUCTlVIt.VESS. 



1 1 lias been but a few years since entomologists considered the common 

 mealy Inig {Pseudococcus citri Risso) as simply a troublesome greenhou.se 

 jiest, which would scarcely be able to thrive in the orchards, though it was 

 early recognized as a feeder on citrus trees in Europe. To-day citrus growers 

 in Southern California are seeking everywhere for methods and means of
