4 ANNUAL REPORTS OF DEPARTMENT OF AGRICULTURE, 1933 
Collections of over 400,000 female gypsy moth pupae were secured near Middle- 
boro, Mass., and from them over 166,000 females emerged. The tips of the 
abdomens of these insects were placed in a solvent and used in small cages for 
the purpose of attracting male moths. Two hundred and fifty moths were 
caught at 105 cages during the season, and some of these catches gave important 
clues as to the location of new infestations. 
GYPSY MOTH WORK ON LONG ISLAND 
The New York Conservation Department scouted selected areas in Queens 
County, North Hempstead and Oyster Bay towns in Nassau County, and 
Smithtown and Brook Haven towns in Suffolk County, Long Island. No 
infestation was found in Queens and Suffolk Counties. Twenty-three infes- 
tations were located in Nassau County, 13 of them being found in North Hemp- 
stead and 10 in Oyster Bay town. All these infestations were found in an area 
of approximately 2 miles in radius from North Roslyn. This area has been for 
several years under State quarantine, and all shipments proceeding from it are 
inspected and certified by Federal inspectors. During the year over 4,000 ship- 
ments, including nursery stock, forest products, etc., have been so certified. 
Two small infestations in Oyster Bay town were found about a mile north of 
this area. One of them was in a lumber yard and the other not far from a nursery 
establishment. Both of these locations have been placed under quarantine and 
in addition to the clean-up work that has been carried on in all the infestations 
mentioned, inspection and certification of products that are being moved has 
been required. 
THE GYPSY MOTH IN NEW JERSEY 
On February 6, 1933, a gypsy-moth egg cluster was found in the township of 
Randolph, N.J., near the Mendham- Randolph-Morris township lines. This is 
in the northernmost part of the area that had previously been found infested. 
Further scouting during the late winter and early spring resulted in the finding 
of 111 new egg clusters. These were treated, and arrangements were made to 
carry on spraying work in June. The location where these egg clusters were 
found was particularly difficult to examine carefully on account of the large 
number of ledges and boulders which cover most of the ground area and furnish 
convenient hiding places for the moths to oviposit. Owing to shortage of State 
funds and the need for prompt action, an arrangement was made whereby the 
Bureau furnished a supply of tanglefoot and arsenate of lead, together with a 
fully equipped high-power sprayer, for treating this infestation. The work was 
supervised and the labor supplied by the State department of agriculture. Sixty 
acres of woodland in and surrounding the infestation were thoroughly treated 
during the first half of June 1933. 
On July 1, 1932, Federal work on the gypsy moth had been discontinued in New 
Jersey, but the State department of agriculture continued a limited amount of 
scouting and check-up work throughout the year. This project was supervised 
by a Federal expert who had been in charge of the work in New Jersey for many 
years and who was transferred to the State work with four other expert men at 
the beginning of the year. Over 1,900 cages used for attracting male moths 
were distributed in 51 townships in 6 New Jersey counties. These were located 
directly south and west of the area that had once been infested by this insect. 
No male moths were caught at any of these cages during the year. 
EMERGENCY CONSERVATION WORK 
For many years attention has been called to gypsy-moth infestations between 
the barrier zone and the Connecticut River, and their presence emphasized as 
a constant threat to success in maintaining the barrier zone. 
In connection with the emergency conservation work which is being carried on 
throughout the United States, an arrangement has been made for the organiza- 
tion of a group of men in 10 camps of the Civilian Conservation Qorps in the 
States of Vermont, Massachusetts, and Connecticut to carry on gypsy-moth 
scouting and clean-up work in this area. This work is in the formative stage, 
and it is hoped that with the completion of this organization early in the coming 
fiscal year it will be possible to find and treat the more heavily infested areas so 
that westward spread into the zone may be curtailed.
