CONNECTICUT ENTOMOLOGICAL MEETING

different angles and viewpoints. He regretted that entomology has not had the 
opportunity to develop at Yale as at Cornell, Illinois and many other Universities. 
Professor L. B. Crandall, Extension Specialist in Beekeeping at the Connecticut 
Agricultural College, Storrs, discussed the opportunities for beekeeeping in Con¬ 
necticut. Most beekeepers practice beekeeping as a side line, and the older ones will 
not change their methods. The greatest hope for the future of the industry in Con¬ 
necticut lies in interesting the younger men and women in the subject. 
Mr. L. H. Worthley, Agent in Control of European Corn Borer, Bureau of En¬ 
tomology, addressed the meeting on the discovery, spread and present distribution of 
the European corn borer in the United States. He explained the methods of con¬ 
trol, quarantine enforcement, and how the Bureau of Entomology carries on this 
work in co-operation with the States which are infested. This infestation now in¬ 
cludes all of the New England States, New York, Pennsylvania, Ohio and Michigan. 
Ontario, Canada, also has a large area infested just north of Lake Erie. Mr. Worth- 
ley showed these areas on a large map, and called attention to an exhibit of photo¬ 
graphs and specimens in the rear of the hall. 
Mr. Donald J. Caffrey, who has charge of the European Corn Borer Laboratory, 
maintained by the Bureau of Entomology at Arlington, Mass., spoke of the light 
infestations found along the Connecticut shore, and called attention to the fact that 
two generations occur annually at the Long Island infestation as in eastern New 
England, and the borers are found in both corn and weeds. In the infestations 
around Albany, and surrounding Lake Erie, there is only one brood of larvae, and 
they are found almost wholly in corn. The double-brooded borers attack 200 differ¬ 
ent plants, and they increase many times faster than the single-brooded insect. 
In Connecticut, much sweet corn is grown for seed. This is left for a long time in the 
field and if subject to two broods of borers, will be injured much more than by the 
one-brooded insect. In the dent corn belt of Hungary, where there is only one brood, 
there is seldom any injury to the ears, but all occurs in the stalks. This, however, 
affects the-size of the ears. In regard to parasites, only slight parasitism is claimed 
by European writers, but since the Bureau established a laboratory for this purpose 
in France, Dr. Thompson has found eight or ten parasites present in appreciable 
abundance. These have been multiplied and liberated in this country. Some are 50 
per cent, effective, and two have been recovered. 
At 12:30 a recess was declared and nearly all went to the Yale Dining Hall and 
partook of a cafeteria luncheon, reconvening at 1:45 P. M. 
Mr. R. B. Friend, Assistant Entomologist, Agricultural Experiment Station, 
New Haven, gave an account of his experience in trapping cabbage maggot flies dur¬ 
ing the past season. Though many different baits were tested, one of the most 
effective consisted of the residue left from a partial distillation of an alcoholic extract 
of the cabbage plant, mixed with honey, yeast and water. This was placed in the 
pans of Hodge fly traps distributed in the field perhaps twenty feet apart. In one ex¬ 
periment with 12 traps, 1841 female and 583 male flies were captured between May 
16 and June 10. About 80 per cent, of the females contained eggs. The numbers 
given include two species, the cabbage maggot, Hylemyia brassicae Bouche, and the 
seed corn maggot, Chortophila cilicrura Rondani. There was only a slight infesta¬ 
tion of plants by the cabbage maggot where the traps were used. 
Mr. B. H. Walden, Assistant Entomologist, Agricultural Experiment Station, 
New Haven, in Hints on Photographing Insects, explained the development and
