PSACH • 
PLUM GUEGULIO ( Cono tracheitis nenuphar Hbst.) 
Connecticut. P. Garman (May 19); Beetles of plum curculio out of hiberna- 
tion in New Haven County hut not working on fruit as yet. 
Delaware. L. A. Stearns (May 23): The first overwintered adults were 
collected by jarring on April 17 at Bridgeville. Injury "by first- 
brood grubs subnormal. 
Pennsylvania. H. E. Hodgkiss (May 2~f): First observation of plun curculio 
in Lancaster County v/as on May 11, when they were feeding on apple and 
plum. No feeding seen on peach, even where interplanted with apple. 
Maryland. E. N. Cory (May 13): Plum curculio was found ovipositing on 
poach on May 13 at Avanel. 
Virginia. W. J. Schoene (May 26): A heavy second brood of the plum curculio 
is in progress. The overwintering adults reached the orchard between 
April 2k and May 25. Large numbers arrived about May 1. The wormy 
peaches were dropping in large numbers on May 20-23, infestation 
running as high as 95 percent. In one orchard drops in the center of 
the peach block averaged 50 percent wormy and those on the outside of 
the blocks averaged 90 percent. The fruit is very small, about 1,000 
to the gallon. 
Georgia. 0. I. Snapp (May 6): The peak of first- brood larval emergence 
from peach drops at Fort Valley occurred on May U, which is 6 days 
later than the peak emergence in 1935* (May 25): Nearly all of the 
overwintered adults are dead, as revealed ''oy recent jarring of 
commercial orchards at Fort Valley. First-generation adults have not 
yet started to emerge. 
Ohio. T. H. Porks (May): Scars from : the plum curculio are very scarce 
and no special sprays on apple have been necessary. 
Indiana. L. F. Steiner (May 21): Injuries were noted at Vincennes on Ben 
Davis apples as early as May 5. only a few days after petal fall. The 
pest is more abundant than usual and is doing considerable damage 
throughout the district. 
Illinois. W. P. Flint (May IS): Plum curculio is more abundant in southern 
Illinois than it has been at any time during the past 3 years. Jarring 
records made by S. C. Chandler show a considerable increase in numbers of 
adults taken during the past 2 weeks. The wet season of 1935 certainly 
enabled this beetle to stage a strong comeback. 
Michigan. R. Hutson (May 9): On May 8 we jarred some trees at Mason and 
East Lansing. C. nenuphar was recovered at both places. These recover- 
ies were, without doubt, due to the extremely warm weather of the 
past few days. The buds are in the prepink stage.
