recently been placed in charge of the Panama project and will pra 
the investigations started by H. F. Dietz in 1918, Mr. Zetek is a 
graduates of the University of Illinois and for the past ten years has 
been engaged in entomological work in Panama and the Canal Zone. The 
Bureau is particularly fortunate in securing the services of Mr. Zetek 
who i8 so well versed in the entomological problems of the Canal Zone

work will include the study of injurious tropical and subtropical insects 
such as the black fly and fruit flies. He will also make a study of the 
important fruit insects, and those passing through the canal from 
foreign countries, as a basis for any necessary quarantine action. He 
will therefore be carried part of the year on the rolls of the Federal 
Horticultural Board, | | 
R. EB. Nolen has been appointed field assistant in insect control 
and will continue the camphor thrips investigations at Satsuma, Flas 
which were temporarily interrupted by the resignation of C0, A. Bennett. 
This work ig being conducted under the field direction of W. W, Yothers. 
Dr. Wm. Mann has recently completed a report on his trip to 
Spanish Honduras, in which he lists the injurious insects of that 
locality. He collected several new species and discovered a new parasite 
which almost completely controls the coconut white fly in that country. 
CG, L. Marlatt recently conducted a hearing at Birmingham, Ala., 
on the subject of the Mexican bean weevil, at which State and Federal quaran. 
tine action was discussed and formulated. Later, in company with members of 
- the Federal Horticultural Board, the pink bollworm situation in Texas 
was reviewed and certain amendments made to the quarantine affecting the 
movement of cotton lint from the El Paso district and the movement of 
‘linters from regulated districts in Louisiana. The Thurberia weevil 
situation in Arizona was then studied in cooperation with the State 
authorities for the purpose of determining the necessary quarantine action 
which the recent spread of this insect to cotton cultures demanded, It is 
understood that the district invaded by this insect near Tucson will 
hereafter be maintained by the State as a noncotton zone. The control 
of the date palm scales at Indio and elsewhere in the Imperial Valley 
of California was investigated and an agreement was reached to strengthen 
the control work with respect to this insect if funds could be secured. 
With such strengthening the outlook is extremely promising for ths complete 
extermination of the Parlatoria scale. At Los Angeles the citrus station 
was visited and a cooperative plan of work was agreed upon between the 
station of this Bureau, now under the charge of A. D. Borden, and the 
educational, extension, and other work which is being undertaken by “the: 
California Fruit Growers’ Exchange; in relation particularly to fumigation
