ping conditionse In fields pishted to tomatoes in 1943 counts ran lea and 
5e5 per square foot; in fields planted to wheat there were 4.5, 8.2, and 
9.5 per square foot; in fields where asparagus Was grown the averages were 
4.9 and 8,4 per square foot; in a rhubarb field the count was 2e2 per square 
foote In an old. corn field there were 1507 grubs per square foot around 
the old stubble, but only 4.7 per square foot tetween the hillse Several 
orchards gave counts of less than 1 per square foot, but in one cherry 
orchard that was entirely defoliated-in 1934 there were Tad grubs per square 
foot between the trees and 861 under the trees. . In a pasture in this same 
area grubs averaged 15.2 per square foot. Three. cases of larval injury to 
strawberries have been reported in Maye 
| _ Improved laboratory spraying apparatuse--We E. Fleming, of the Mooress 
town, NeJ., laboratory, has devised an improved apparatus for applying 
materials as stomach-poison insecticides to foliage. Fifteen revolving 
discs were mounted on a révolving eircular, table so that the plants placed on 
these discs pass through the spray from a fixed spray gun and are uniformly 
coated: on all sides. The spray mterial is placed in a glass tank, equipped 
with a mechanical agitator, and flows by gravity to the spray gune The spray 
is applied at a pressure of 25 pounds to the square inche The apparatus can 
be operated rapidly and plants sprayed uniformly for insecticide tests under 
controlled conditionse 
Status of imported parasite gJap beetlee--Je We Balock, of the Moores= 
town, N.Je, laboratory, reports that apparently the extreme winter had no ill 
effect upon Tiphia vernalis Roh., as this species appeared at its normal 
season, the second week in May, and during favorable weather appeared ih as- 
tonishing numbers in several of the older colonies. The record catch was 
1,682 females in 3 hairs’ time, collected by 3 mene While all notes are not 
as yet. assembled, it is estimated that close to 150 new colonies were placed 
in the field this season, thus the total number is approximately 347. Te Re 
Gardner, who scouted DE pt colonies placed in the field in 1942, made re- 
coveries in 41 of these, /or 72 percent. He states that some of these showed 
a very good build-up, as hundreds of mies and females were observede 
Tiphia sp» Nos 29, an imported parasite of the Hap beetlee--Le Be 
Parker, of the Moorestown, N.J., laboratory, reports that adults of this 
species began emerging from stored, foreign-reared cocoons on May 1l, am 
that they ceased emerging on May 26. The sex ratio in the total adult 
emergence was practically even. Total emergence was 4,140 adults, or 63 el 
percent of the total number of cocoons set up. 
Asiatic beetles (Autoserica castanea Arrow and Anomala orientalis Waterhe) 
Distribution and abundance of the Asiatic garden beetle in and around 
Philadelphias~-I. Me Hawley, of the Moorestown, N.J., laboratory, reports 
that in grub surveys made in the Philadelphia area to determine the abundance 
of the Japanese beetle, data relative to the presence of the Asiatic garden 
beetle(Autoserica castanea Arrow) in this area were also obtained. With the 
exception of Riverton, N.J., all the locations are in Pennsylvania. The data 
obtained are as follows:
