H. 3. Adair (September 22): The cotton leaf worm was reported 
at Brc-.-'ir.vood by county agent Z. P. uriffen as doing quite a bit 
of damage in a few sections of the county the first part of August. 
The post has apparently been held in chock by the continued dry 
weather; however, it has been extending its range and recent ob- 
servation shows quite a bit of feeding in fields which had formerly 
been free from infestation. Mo damage to the crop is likely to 
occur this season.

Arizona News Letter Pol. 3. he. 8 (August 31 ): A species of 
mealybug appeared on cotton in the latter part of the month. 
Three 'Widely separated outbreaks were reported in the Salt Piver 
Valley. The most serious of these was near Phoenix south of the 
Salt Piver '.-.here approximately 2 r ores of cotton was partially 
destroyed by the insects. The outbreak was checked by cutting 
and burning the infested plants. The lesser outbreaks -ere found 
near Pes--, and C-ler.Plo. At the latter -place a heavy rain checked 
the insects before any material damage was done.

P. A. McGregor (September 15): Pais constitutes the largest and 
severest ca.se of bean thrips injury to cotton '" T o have ever cbsorvh.. 
Not a plant on the entire 350 acres was probably entirely free of 
the pest. Some spots comprisi:v% -an area of from 2 to 10 acres 
had become so severely infested that the plants had become rooro 
or less denuded of foliage and only the older bells were retained. 
A great deal of daraago had resulted. A good many predators :rcrc 
present, especially Prijhleps, Hhinacloa, Chryscpa, and reduviids. 
CGBT/OP SQTP-JPW D;jJBPP (hy us elisus Van P. ) 
P. A. HcGregor (.""eatembcr 15): An estimate of 50 per cent damage 
to cotton is merely a rea r k approximation and should not be taken 
as final. A largo number of squares and very young bolls were 
examined, 50 per cent of -hich had been nfurg -rid were doomed to 
shed. In addition, many of the old dry squares (en the ground 
or adhering to the stalks) were found to have unmistakable evidence 
of having teen killed by Lygus. Probably this is the severest 
case of Lygus damage ever observed.
