a fungus disease. The Pacific red spider ( Tetranychu s r>acificus MeG. ) did 
damage to certain varieties of grapes in the San Joaquin Valley of Cali- 
fornia, "being one of the outstanding pests in that section this year. A 
European species of mite ( Fhyllocoptes fockeui Mai. & Tr. ) was discovered 
this spring attacking the leaves of nrune trees in southern Idaho. These 
mites produced a decided russeting of the foliage. The insect was quite 
abundant and is apparently the cause of a tyoe of injury which has "been 
very severe in recent years. As far as we can ascertain, this species has 
not "been previously recorded froii the United States, "but was collected on 
plums in the vineyard district of Ontario in 1923 (Can. Ins. Pest Review, 
Vol. 6, No. 5, October 5, 1928). Although a gall mite, this species does 
not appear to nroduce galls or blisters. 
CITROPHILUS MEALYBUG 
Control of the citrophilus mealybug ( Pseudococcus gahani Green) by the 
coccinellid Cry-ptolaemus montr o uzieri Muls. and the hymenopterous parasite 
Cocconha^us guencyj Co-mo. in Los Angeles County, Calif., has been extremely 
gra.tifying. Over 99 ner cent of the 20,000 acres of citrus in this county 
recorded as having been infested with this mealybug are so slightly in- 
fested this year that no damage could possibly be done to the crop. In 
1931, 97 per cent was in this condition, while the average for the preceding 
six years was but 83 ner cent controlled. Thirty- three per cent of the pre- 
viously infested acreage was found to be no n- infested this year. Last year 
this reduction in infested acreage was but 25 per cent. It is believed 
that the nev : hymenopterous parasite has played an imnortant nart in reducing 
the infestation. 
MEXICAN FRUIT tfOEM 1 
The outstanding development in the Mexican fruit worm ( Anastreoha 
ludens Loe-w) situation was the finding of an infestation, after an interval 
of approximately 17 months, on the United States side of the Rio Grande. 
This infestation was discovered on Aoril 22 in fruit held in storage in 
Mission, Tex. Previous to this oranges produced in a patio in Matar.oros 
were found infested on April 9. On/both -April. 15" and:-lS -an" adult 
caught in traps located at a distance of 11 Diid. 5 blocks from this uatio. 
During July 30 flies were taken on 13 different premise", in the city of 
Matamoros", 23 adults were taken during August in traps in I^atamoros and 
2 specimens, ( Anastrenha -pal lens Coq.), were collected, one in a grove near 
Mission and the other in a grove near Brownsville, Tex. This sueciec was 
first described from specimens taken at Brownsville in 1904. Nothing is 
known of the food plants of this soecies.
