MEALYBUGS ( pscudococcus spp.) 
California. H. J. Ryan (.February 21): Occasional infestations of P. mari- 
timus Ehrh. , and P, citri Risso still require liberations of the 
ladybeetle C ryptola -ous mont rouzieri I.luls. Control of P. gah ani 
Green has been maintained by the parasites Cocco")lia£us gurneyi 
Compere and Tetracnemus pretiocus Timb. 
A SCALE I1TSECT ( Lepi do sashes halli Green) 
California. M. L. Jones (February 25): Surveys are in progress to estab- 
lish the possible distribution of Hali J s scale in the Cliico district 
of Butte County. To date, all evidence indicates that it has not 
spread from the United States. Plant Introduction Garden. Eradication 
of this scale during one season was attempted in the spring of 1935* 
The only survivors found to date were four individuals on one tree. 
The group containing this tree is isolated and has been given a very 
drastic treatment. All stone-fruit trees leaving the station, about 
3,b00 in number, have been treated by vacuum fumigation. 
CALIFORNIA BED SCALE ( Chrysomphalus aurantii Mash. ) 
Arizona. C. D. Lebert (February 2U): Approximately 10,000 citrus trees 
are being fumigated in the Phoenix area. It is hoped that complete 
eradication of this pest will be achieved. 
GREEN CITRUS APEID (Aphis spiraecpla Patch) 
Florida. J. R. Watson (February 2H): The first part of the winter was 
very dry. Since then it has been cold and wet. These conditions 
were very unfavorable for the development of the citrus aphid, as there 
was no food in the early part of the winter and it has been too cold 
for rapid development since. Aphids ere at present about as scarce 
rs I have ever seen them.
