area. An intensive reexamination disclosed that the premises of 10 
growers in Hidalgo County were involved in this reinvasion. (Plant 
Quarantine and .Control Administration.) 
CITROPHILUS MEALYBUG 
The parasite Coccophagus gurneyi Compere of the citrophilus mealy- 
bug- ( Pseudococcu s gahani Green) has now been proved sufficiently 
adaptable to California conditions to make possible its propagation and 
distribution commercially for the control of the pest. During the 
past season 172,000 parasites were liberated over a wide area for 
establishment purposes only. Potatoes represent an extensive item in 
insectary operations for the propagation of the lady beetle Crvptolaemus 
montrouzieri iviuls*, used to fight the mealybug in Los Angeles County, 
Calif. Approximately 2,000 sacks of high-grade potatoes will be 
required in the operation of the laboratories at Downey and Rivera 
during the coming season. The potatoes are used in developing sprouts 
on which the mealybug is grown as food for the lady beetles. This 
quantity of material should easily produce the 10,000,000 beetles 
estimated as required to meet the field need next season. Production 
will start in March and reach a peak during April, May, and June. At 
present the mealybug situation in the field looks more satisfactory 
from the standpoint of control than it has for several seasons. 
RASPBERRY FRUIT WORM 
The raspberry fruit worm ( Byturus uni color Say), which has been so 
injurious to loganberries in Washington State, seemed more prevalent 
than last year and was observed this year destroying strawberries and 
causing injury to the petioles of apple and cherry. This insect also 
caused very considerable damage to red raspberries in the lower Hudson 
River Valley of New York State and attracted considerable attention in 
Minnesota, Wisconsin, and southwestern Michigan, 
PEA APHID 
Late in March the pea aphid ( Illinoia pisi Kalt,) was reported as 
doing rather severe damage in many localities in Florida. This insect 
was very abundant in Virginia throughout the winter on alfalfa and in- 
creased very rapidly during the spring, causing considerable damage. 
In the Pacific Northwest it was so scarce that specimens were difficult 
to find in vetch where it usually has been quite abundant. Continued 
cool, rainy weather in April retarded the development of this insect 
in the big cannery district of Wiscdnsin. During the remainder of the 
season no unusual conditions were reported.
