observed in the spring condition of the buds between vineyards treated with 
nicotine, last season for control of leafhoppers and vinéyards not so treat- 
ede The dry summer of 1934 made conditions especially favorable for leaf 
hopper increase, heavy infestations causing burning or loss of foliage and 
consequent poor ripening of bearing canesSe In nicotine-sprayed vineyards 
the leafhopper population was reduced to a point where little injury was done, 
the foliage remaining green and in good condition until late in the seasone 
In these vineyards comparatively slight winter injury to the grape buds has 
been observed, whereas in nearby or adjoining vineyards where leafhopper in-= 
jury to the foliage had been severe, more winter injury occurred, in some ine 
stances the freezing of primary buds running as high as 40 percents 
Improved facilities for work on parasites of oriental fruit moth.=-~= 
As a result of construction under a CWA allotment, completed early this 
spring, the oriental fruit moth project at Moorestown, NeJe, now has a re~ 
constructed insectary unit which is well adapted to the wrk in progress. 
It contains a block of rearing cages for mass production, with a maximum 
capacity for about 750,000 fruit moths (Grapholitha molesta Busck) with as= 
sociated cages for rearing and inoculating the host, a quarantine room for 
rearing all foreign importetions, two heated rooms for incubators and forced 
rearing in early spring and fall, a large cold storage clamber, a cage with 
humidified closet for recovery rearing, and ample and convenient storage 
for rearing equipment. 
Insect injury to raisins.--Samples of raisins of the 1943 crop, col- 
lected during April and May from storage in open-sided sheds, were examined 
by Heber C. Donohoe of the Fresno, Calif., laboratory. Muscat raisins 
(4 samples) were damaged by feedihg at the rate of from 91 to 402 pounds per 
ton, Thompson Seedless (5 samples) from 91 to 320 pounds per ton, and Sultana 
(3 samples) from 259 to 450 pounds per tone (These figures represent injured 
berries per ton, not weight loss per tone) Before drying some of the ber= 
ries had been fed upon by Drosophila sppe, and minor damage by the saw-toothed 
grain beetle (Oryzaephilus surinamensis Le) had occurred while the raisins 
were in storage. The major part of the feeding was by the raisin moth 
(Ephestia figulilella Greg.). When examined, the fruit still contained from 
none to 28,900 per ton of living am dead larvae, pupae, and adults of this 
speciese 
Dried fruit beetle unusually abundant.--A summary of census trapping 
of Carpophilus hemipterus Le, by Dwight F. Barnes, of the Fresno, Calif., 
laboratory, shows the insect to be exceptionally plentiful this yeare The 
comparative catches are; 1931, 21,800; 1932, 1,800; 1933, 15, 000; 1934, 
29,600. Infestation of figs and consequent potters by souring’is likely 
_ to be prevalent during the rfpening of the main crop in July and Auguste
