G. A. Runner, in charge of the grape insect work ror the Bureau of 
Entomology at the Federal latoratory at Sandusky, Ohio, reports severe 
injury from grape leafhoppers in vineyard sections of New York, Ohio, and 
Michigan, and that large mmbters cf gape gvowers have commended spray- 
ing operations for contrul, In Chio and Michigan the grape=berry moth 
has caused nore than the usual anowmmt of demage to the grape clusters by 
feeding on the stems or buds during the blossoming period. At Lawton 
Mich,, on June 8, Mr. Rurnexs feud cocoons of the grape-berry mota on the 
Gtape leaves. This shows az unusually early development of the larvae, 
as grapes were just cut of Liscxu, and shows that early appearing larvae 
are able to complete fully their gow. h'without entering the grape ber- 
ries. At Paw Pew, Mich., sud clusters infested With the grape-blossom 
midge (Contarinia gonnseni Slinge) were observed on June 8. The insect 
had not oeen reported from that section previously. 
Dr. Guy C. Crampton, of the Department of Entomology at the Massachu- 
Setts Agricultural College, visited the Wallingford station July 7 and &. 
The Japanese beetle has been much more abundant duting the present 
Season than in any previous year and over a wider area, Serious damage 
has been caused by the immense numbers of the beetles to the foliage of 
Many trees, especially fruit trees and certain varieties of shade trecs. 
There has been important injury to early fruit, particularly early apples 
and early peaches. The height of the beetle season is at hand and a clear 
idea of the extent of heavy feeding can now be obtained. 
Recent visitors at the Japanese Beetle laboratory include Dr. E,. D. 
Ball, Dr. L. 0. Howard, Dr. A. Le Quaintance, and Dr, ¢. L. Marlatt from the 
Department. Other visitors include Dr. T. J. Headlee, State Entomologist of 
New Jersey, and Mr. H. B. Weiss of the State Department of Agriculture, New 
Jersey, and Prof, F. Rasmussen and Prof, J. G. Sanders of the Pennsylvania 
Department of Agriculture. A committee of the New Jersey State board of 
agiculture also recently spent part of a day at the laboratory looking over 
tne beetle situation. 
The citrus black-fly, introduced into the Canal Zone from the West 
Indies, is rapidly spreading, according to Mr, James Zetek, who is in charge 
of tne field station there, Tunis pest is now well distributed for about 12 
miles out from Panama City, all along the Canal Zone, and has been introduced 
in the interior at Aguadulce. Two entomogenous fungi, Aschersonia aleyroais 
and Aezerita webberi, are following the black-fly but are not suiricient to 
cneck it. Agriculture is still in its infancy in Panama so that practically 
no control or restrictive measures are being taken against any pest. 
Mr. Zetek also reports thepapaya fruit fly very abundant and well ais- 
triouted wherever papayas are grown. In some of the papaya groves the damage 
wue to this species amounts to 90 per cent of the crop. In some parts of 
the interior of Panama it is impossible to grow papayas without having then 
infested, unless the very taick-flesied varieties are grown, The picking and 
destroying of infested papayas, and allowing chickens to live in the grove, 
are the two most efficient control measures.
