■ORANGE MAGGOT (Anastrepha ludens Loew) 
On November 4, one adult was caught in a trap in Matamoros, Mexico, 
just across the river from Brownsville, Tex. About 100 traps, baited 
with orange extract, are kept in the citrus trees growing in the patios 
in Matamoros. Inspection of the imported fruit in the uubiic markets re- 
sulted in the finding of 43 larvae.' 
December, 1930, was the first complete month in which no adult flies 
have been collected since the infestation at Matamoros was found in Sep- 
tember, 1929. 
During February 32 larvae were taken from oranges offered for sale in 
the market at Matamoros-.; .These oranges originated at Montemorelos, 
Nuevo Leon,, which is located about 100 miles below the border. Fruit 
imported to the market at Matamoros from the southern part of the RepuV- 
blic of Mexico showed a heavier infestation in February than at any time 
since September, 1930. A total of 241 larvae were taken from fruits 
which were discarded by the merchants.' Many of the infested fruits are 
sold before evidence of injury becomes apparent. 
This insect was found near Monterey, Nuevo Leon, Mexico, in pista- 
chio nuts ( Pistacia vera ) . This represents our first record of the in- 
festation of pistachio nuts. . ... .... 
PARLATORIA DATS SCALE ( Parlatoria blanchardi Targ. ) 
Considerable intensive inspection was carried on in all areas and 
seven infested palms were found — five in the southern part of the Imperial 
Valley, t:?o. in. the Coachella Valley, and none in Arizona. A survey of the 
northern part of the Imperial Valley .was completed during March and no 
scale found. No scale has ever been reported from this area. 
During the past calendar year fewer infested palms were reported in 
the Coachella Valley than during any year since the work was inaugurated 
in 1914. 
During the past four months 3,109 fan palms were inspected in areas 
in the Coachella Valley where date palms heavily infested have been found 
in the past five years. Forty-five palms were' found lightly infested, 
and these all within 300 feet of a rather heavily infested date palm. 
A new infestation of 20 palms in the Imperial Valley was found during 
January. This planting consisted of 2.9 seedling palms about 16 feet high. 
One leaf on one of the palms was very badly infested. The infestations 
on the other 19 palms were light.
