construction of lenses and the advantages of anastigmatic lenses over other types for 
scientific work. The most convenient outfit for photographing field operations is a 
small camera of the roll film type. The use of short focus lenses for laboratory 
photography was discussed, including micro-lenses for direct enlargements. He also 
mentioned the use of cut films in place of glass plates. 
Mr. John T. Ashworth, Deputy in Charge of Gipsy Moth Work under the State 
Entomologist, with headquarters at Danielson, described the field work in suppress¬ 
ing the gipsy moth. Fifty-two towns were scouted and 21 others partially scouted 
last year by State men, besides some 25 towns along the border of the infested region 
which were covered by Federal scouts. Each crew is provided with a Ford light 
delivery truck in which they go to and from their boarding place. Egg-clusters are 
creosoted, and the worst infestations sprayed the following summer. This work is 
done in co-operation with the Federal Bureau of Entomology. Infestations are 
slight and scattered in Connecticut, and due to the control work, there has never 
been any stripping. In that part of the area longest infested, the gipsy moth is not 
as prominent as it was six years ago, and it is believed that the parasites are holding it 
in check. 
Mr. A. F. Burgess, Melrose Highlands, Mass., who is in charge of the Federal 
gipsy moth work, referred to the satisfactory co-operation in this work between 
Federal and State forces, and called attention to the danger in the present conditions. 
People do not see damage and do not realize that the gipsy moth may again increase 
and therefore may not make adequate appropriations for the work. Ten years ago 
conditions in New England were certainly alarming. Now there is little stripping 
anywhere. Much research is necessary to develop the best control methods, and the 
quarantine regulations probably have prevented much dissemination of the pest. 
Parasites have been collected in Europe and other countries, reared in the laboratory 
and liberated in the infested area. The gratifying results now apparent should not be 
attributed wholly to the work of parasites. Creosoting, spraying and low tempera¬ 
ture have all helped to reduce the pest and no man can tell whether this combination 
will continue. Mr. Burgess explained the barrier zone plan and gave a favorable 
report on the work of eradicating the pest in New Jersey. 
Mr. Samuel S. Crossman, of the Parasite Laboratory in Melrose Highlands, Mass., 
gave an account of his recent trip to Europe in search of gipsy moth parasites, de¬ 
scribing various conditions which he found there. 
Dr. Philip Garman, Assistant Entomologist, Agricultural Experiment Station, 
New Haven, gave a history of the Oriental peach moth in Connecticut, and reported 
its increase and spread in 1924. The pest was discovered in Stamford in 1917, 
larvae were found there in 1918, but little trace of the insect was again seen until in 
1923, when it caused serious injury to fruit in one orchard in Greenwich. In 1924, the 
damage was even greater and the pest occurred throughout the southwestern third of 
the State, and one report of wormy peaches came from central Connecticut near the 
Massachusetts line. The larvae winter in cocoon-like cases on the bark near the 
ground and probably emerge late in May or early in June; they first appeared in 
twigs at Greenwich about the middle of June in 1924. The first infested fruit was 
found July 14. There are probably three broods in Connecticut, the third hibernat¬ 
ing. Eggs are laid on the leaves and hatch in from four to eight days. Adults fly 
actively late in the afternoon. The larvae often leave their twigs and enter other 
twigs or fruit. Cocoons are made anywhere on the tree or ground. One parasite has
