red spider injury to ^ec r n trees in .Jackson County From R. F. Colmer. 
Luring January end February Kimble Harmon reported that red spider 
injury to citrus plants varied from -slight to severe a't Gulfport. 
From the same place Z. K» Bynum on January- 9 reported medium damage 
to citrus and on February 12 he eeported an express shipment of 
citrus plants from Alabama' -ith a "medium" infestation of .red

PECAN LEAF CASE 3EARER ( Acrobasis nebulella Riley) 
North Carolina p.. W« Leiby (March 23)-: Gomple folia-ion in the largest 
pecan orchard of the State is> threatened "by the pecan leaf case 
hearer. Examination 'of 1-9 buds. shows an average of H.01 hiber- 
nacula per hud. Of these 35-5 P^ r cent show living larvae, 8 per 
cent dead larvae, and 6.5 pen cent larvae parasitized by Secodella 
acrobasis . A similar condition, but not quite so severe, existed 
in the spring cf I9"i&» which ras followed by almost complete 
defoliation. Spraying will' be essential as additional' parasites 
■•;ill not be- effective until larvae are nearly full grown'. The 
last outbreak was nine and ten years ago* 
Mississippi R. \7. Harned (March 27): Has been reported as abundant in certain 
piaces along the C-ulf Coast. 
CITRUS .. ' ' 
CITRUS NEMATODE ( Tylenchulus semioenetrans Cobb,) 
Arizona Arizona News Letter Vol. \ No. 2, Feb. 285 The citrus nematode, 
a parasite en the root sys'i ems of ci trus trees in .'practically' 
all part's of the ■ orld, ha fee ntly t en disco v in some of the 
citrus groves of Arizona. The distribution and spread of this 
pest • throughout the citrus district's of this State have net yet 
been determined but efforts are being made to ascertain t v is at an 
early date. " , ■ 
It has been the opinion of (agricultural and horticultural 
investigators that this pest was not present in Arizona. Recently 
one of the ci trus growers northeast of Phoenix requested a special 
examination o^ the root systems of some of his trees. In complying 
with this request some of the root systems -ere brc t into the 
laboratory, given a careful washing under the tap, and later were 
xamined microscopically for the presence cf nematodes. The first 
mounts showed the presence of heir were at once sus- 
pected of being the typical citrus nematode. More material was 
collected and bent to the citrus experii station of California, 
and to the "J. 3. I nent of Agriculture, for the correct 
determination of this parasite. At a later date specimens were 
collected and examined by the Plant Pathologist of the University 
of Arizona. 
Reports have been received from each of these three sources, 
confirming the identification cf the organism as the citrus nematode.
