HUH I TEFL IE S ( Dialeurodes spp. ) 
Florida, J. R. Watson (April 2l): In most sections of the Citrus Belt there 
seems to be an unusually heavy flight of vvhiteflies this year. D. c i t r i 
Ashm. has largely emerged in the southern part of the Citrus Belt, but 
is just beginning to appear in the northern part around Monticcllo, ac- 
cording to S. 0. Kill. The cloudy-winged species(£. citrifolii Morg. )is 
beginning to appear in the main part of the Citrus Bolt.

Georgia. T. L. Bissell (April 5) : More than usually prevalent in southern 
Georgia counties during the winter and spring. I have reports from 
Claxton, Evans County, and Reidsville, Tattnall County, both in south-

CALIFORNIA RED SCALE ( Chryeomphalus aurantii Mask.) 
Arizona. C. D. Lebert (April 20): California red scale apparently absent 
this spring in the Phoenix area. Unable to find a single live scale. 
Tie hope the pest has been eradicated. 
CITRUS THEIPS ( Scirt othrips citr i Moult.) 
California. R. S. Woglum (Anril): Citrus thrips have been hatching for 2 or 
3 weeks in central California and in some placer- are now fairly abundant 
in spite of the cool and rainy weather. Owing to the delayed and pro- 
longed hatch the thrips will not appear to be as abundant as they some- 
times are at this time of year. Thrips have been hatching more or less 
sporadically since the middle of March, but in the past few days have 
become numerous in some orange orchards in eastern San Bernardino County. 
They are also appearing freely in occasional lemon orchards, especially 
in San Bernardino County in orchards that suffered considerable thrips 
damage last year. 
C. S. Morley (Anril 2): The first citrus thrips were found in 
the Edison district, Kern County, on March 12.
