GIPSY MOTH AND BROWN-TAIL MOTH INVESTIGATIONS 
A. F. Burgess, Senior Entomologist, in Charge 
q On August 22 about thirty visitors, attending a shade-tree conference in and 
about Boston, stopped at the gipsy moth laboratory at Melrose Highlands, where an 
exhibit had been prepared for them, 
4 FP. G. Craighead, of Forest Insect Investigations, called at the office and 
my on August 24. 
{ S. M. Dohanian revorhed from Europe on the S. S. America on August 15, 
after spending most of the last six months in Spain and Portugal, investigating 
the biological control of the gipsy moth, Porihviria dispar. He has made several 
large shipments to Melrose Highlands, Maae., of gipsy moth larvae and pupae, and 
several lots of gipsy moth parasites and oe: Fe ee As a result of these ship- 
ments several parasite colonizations have been made. He reports heavy gipsy moth 
infestestations in parts of Spain and Portugal. The parasitism of the gipsy moth 
in these two countries was not 30 great as in parts of central Europe. He receiv- 
ed splendid cooperation from the official entomolegists in both Spain and Portugal, 
finding it a great help to the work. After the gipsy moth geascn was over in those 
countries he coneulted with. entomologists of the United States Bureau of Entomology 
at Hyeres, France, at Rome, Florence, and Fano, Italy, ard at the meeting of the 
b ira International Congress of Entomologists at Zurich, Switzerland. In the 
southern part of France the gipsy moth infestation is very light, as it has been 
for several years. In southern Italy a heavy gipsy moth infestation is reported 
near Potenza, in the Province of Basilicata, and light infestations were located 
at Genoa and at Atessa, near Venice.
