The first report was received from Prof, 3., E„ Thomas, of the 
Riverside Citrus Experiment Station of California. Prof. Thomas 
states in part: "i have examined the roots ana find that they 
are infested with the citrus jEamatoda. It is not always possible 
to he sure regarding the nematode unless you locate a number 
of females with their anterior portions embedded in the roots* 
I found a number of females and am positive that it is the 
citrus' nematode." The next report was obtained; from Dr, J. Go 
Brown, Plant 'Pathologist of the University of Arizona. Dr„Brown 
found that the Swollen female nematodes were numerous. The final 
report was obtained from Dr. &„ A. CcYo. Dr. Cobb states, "An 
examination of the grapefruit roots accompanying your letter 
of February 12 sheas them to be infested with the citrus nematode 
jbyj-enchuius.. semitene trans. " Dr. Cobb further stages that in some 
cases the disease has been regarded as very serious, and in others 
of no very great consequence. 
'The Survey worfc which 1ms been done up to the present indicates 
that the organism is present in different secernent of the Salt 
River Valley citrus district. Hoot samples taken irc^i three 
different sections have revealed the presence of the organism 
in as many groves. Samples have also been taken from other groves 
in these sections and no parasites could be found. The seriousness 
' of this -peso and the amount of damage which can be ascribed to 
it will be determined by further Surveys.- D. Co George.
