ml she 
previously infested while in storage, were treated by covering with soil 
containing 10 pounds of paradichlorobenzene per cubic yard. After a week 
the roots were torn apart and examined. In Coreopsis lanceolata and Ar= 
temisia lactiflora all larvae were dead. In Monarda rosea, Boltonia la— 
tisquama, and clumps of Barr's pink aster some sick but no normal larvae 
were found. In clumps of Shasta daisy 3 percent of the larvae were nor- 
mal. All the clumps, however, were'large, some being 8 to 10 inches in 
diameter, and a prolongation of the treatment or a higher dosage would 
probably have given a complete kill. * * * In another test, dormant roots 
of some of the above mentioned varieties were potted in soil containing 
paradichlorobenzene at the rate of 5 pounds per cubic yard. An incomplete 
kill was obtained in most cases, probably because the root clumps were so 
large that comparatively little of the treated soil could be put into the 
pots." 
Control of Jap beetle in lawns and golf courses.--In January M. R. 
Osburn, Moorestown, obtained information relative to turf injury and con- 
trol practices in 1932 from 39 golf courses in the area of heavy beetle 
infestation. All of the clubs visited had used lead arsenate on the 
greens and tees to prevent grub injury, the treatment being considered a 
necessary annual procedure to insure fine turf. Twenty of the 39 clubs 
have grub-proofed the fairways and 1 had treated the rough. Green keepers 
reported that the lead arsenate was applied alone as a dry powder; 
mixed in a top dressing; or as a spray. In most instances the material 
was mixed with inert ingredients and applied with a tractor-—drawn drill. 
Grub injury to turf in the spring was reported on 10 of the 39 courses, 
9 of which were damaged in the fairways and 1 in the rough. Practically 
all of the injury was on untreated areas, with the exception of two areas 
which had received applications of lead arsenate three or four years ago. 
TRUCK CROP AND GARDEN INSECTS 
Bulb-fly counts in narcissus bulbs.--C. F. Doucette, Sumner, Wash., 
who has made a study of the degree of infestation by Merodon equestris 
Fab. in large bulbs as compared with small ones, found the average infes— 
tation in large bulbs (double nose and larger) to be 2.54 percent greater 
than in small bulbs (rounds and slabs). The average infestation in the 
larger bulbs was 6.07 percent and in the smaller 3.53 percent. 
Concerning the infestation by Eumerus spp., Mr. Doucette states 
that "A study of records over the 4-year period, 1928 to 1931, shows 
amined. The records cover a total of 5,577 narcissus bulbs, containing 
a total of 129,606 Eumerus larvae; 50 percent of the bulbs contained 
10 or less larvae; and the largest number of larvae in a single bulb 
was 947." A 4-year study (1928-1931) of joint infestation by M. eques— 
tris and Eumerus spp. shows that 2.24 percent of the Merodon—infested 
bulbs were also infested with Eumerus; that 3.998 percent of the Eumerus 
infested bulbs were also infested with Merodon; and that the total 
percentage of infested bulbs carrying joint infestation was only 1.46.
