KCIT CIT3US AFHIE ( :' -phi s snirrecola Patch) 
Florida J. R. Y/atson (Anril 22): There is a very heavy infestation 
over lost of the citrus belt at the present tine, a nonth 
later than v e ordinarily expect such an outbreak. This is 
undnubtcdly the result of c delayed flush of grorth rnd bloom 
on citrus. The first -nart of the Winter was extremely dry 
and -prevented the treos fro" blooming to any large extent 
or putting out much tender grovth to serve as food. The 
drought vas broken about the middle of March and the trees 
are no* in full bloom and full of aphids. 
OBAJKC TH3IPS ( ScJLrJboJhrrps citri Moult. ) 
Arizona C. D. Lebert (Ar>ril): Very numerous on the citrus in the 
Salt River nnd Yuma." Valleys during April. The second and 
third amplications of sulphur "ore being arrolicd in many of 
the groves. The flower thrips, Tronhlini ell a tritici Fitch, 
T.'erc r.ore abundant in the bloon by far, although it V7as 
not uncommon to find an average of five citrus thrins per 
blosso"" in the older groves. 
California E. A. " r cOrcgor (Aoril 19): Although the citrus thrins 
ap~*c~red !!arch 6, this yerr, six days later than normal, iti 
has developed very ramdiy. It has suffered a minimum of 
mortality, and a high percentage of overv interin;: eggs 
hatched and developed to maturity. This led to a rclrtivc- 
ly gre.^t amount of injury t?. vernal foliage of citrus 
varieties. The outlook is for g year of severe damage to 
unprotected orchards. 
CI THUS 'THIIGFLY ( Dialeurodes citri Riley & Hot.) 
Florida J. R. I7atson (Anril 23): The citrus vhitefly is moderate- 
ly abundant. 
K. T. Fernald (April 20): Far less abundant on citrus 
trees at Orlondo than last year at this tine. 
C. Lvle and assistants (A-nril): The citrus vhitefly is 
very abundant in many localities throughout the State, at- 
tacking citrus, cape jasmine, and ^rivet. (Abstract, J. A. H. )

California »fonthly Kews Letter, Los A n geles County Agricultural Com- 
missioner (March 29): The first major step in securing the 
eradication of infestations of the citrus vhitefly, found re- 
cently in Arcadia, has been taken. Considered a major nest 
of citrus, to which it causes damage similar to that of the 
black sco.le ( Saissetia oleae Bern.) the citrus vhitefly 
before being found at Arcadia was known to exist in Califor- 
nia only in the vicinity of Sacramento, and since September, 
1931, in Santa Ana, Orange County. At both of these places
