JAPANESE BEETLE AND ASIATIC BEETLE RESEARCH 
Wind and water aid in dispersing Jap. beetle.-- From 1. M. Hawley, 
Moorestown, N. J., we have the following: "In the monthly report for July 
it was noted that R. J. Sim had found Japanese beetles being carried 
first by wind and then by water across Delaware Bay from the heavily 
infested area in Cumberland County, N. J., to the eastern shore of Dela— 
ware. Many of the beetles were alive when picked up on the Delaware 
beach. Additional evidence that beetles may be carried in this way 
was found in August, when C, W. Stockwell, of the Bureau of Plant Quar— 
antine, informed us that C. H. Zimmer, in charge of quarantine work 
in New York City, had notified him that on July 29 Japanese beetles 
were being washed up on the south shore of Staten Island, near Princes 
Bay. About 25 percent of the beetles were still alive. A resident 
of Princes Bay, who had observed the beetles, wrote to the Moorestown 
laboratory that, 'As the beetles dried off they at once flew away.’ 
Mr. Zimmer stated further that he was informed by a motor boat captain ~ 
that as he was half way between Keyport, N. J., and the southern shore 
of Staten Island, at a distance of 3 miles from either shore, beetles 
came down on his boat so thick that he could scrape them up with his . 
hands. On August 2 Mr. Zimmer found a distinct line of beetles washed 
on Long Beach. He estimated that there were 100 beetles per linear yard. 
Subsequently he visited Jones Beach, much farther east, and found dead 
beetles, although in smaller numbers. On August 6 the writer was at a 
the Westbury sublaboratory and with H. C. Hallock visited Jones Beach, 
where a few dead beetles could still be found, although many had been — 
tramped into the sand by bathers. The vegetation along the shore was 
examined but no live beetles were found. At the time these flights are 
believed to have occurred the direction of the wind was almost entirely | 
from the southwest, and wind velocity in the warmer parts of the day was _ 
from 7 to 15 miles per hour, although at New York City on the afternoon 
of August 28 the velocity reached 20 miles per hour, The weather was 
hot at this time, especially from July 29 to August 2, and it was expect— 
ed that beetles would be in active flight." 
Unfavorable weather reduces trap catch of Jap beetle. F. W. 
Vetzger, Moorestown, states that "During the month (August) only 1,300,- 
000 beetles were taken in the experimental traps, making the total 
for the season 15,645,000, a reduction of nearly 1,000,000 as compared 
with 1952. The total for July was much greater than for July 1932, but 
the number taken in August was considerably smaller. This is probably — 
accounted for by the fact that the beetles emerged earlier in 1933
