FRUIT INSECT INVESTIGATIONS 
APh;: Quaintance, Entomologist in Charge. 
Mr. C. L. Marlatt’s work as chairman of the Federal Horticultural Board 
has necessitated his relinquishment of the direction of Tropical and. 
Subtropical Fruit Insect Investigations, ‘and Dr. Howard has combined this 
- branch with the office of Deciduous. Fruit Insect Investigations. Mr. Marlatt 
will, however, maintain active cooperation in certain projects, as Mediter- 
ranean fruit fly investigations, the work under way in the Canal Zone, syste- 
matic work with Coccidae, and investigations of insects injurious.to green- 
houses, on account of the intimate relation of ‘this. work. with certain quarantine 
and.other work of the Board. Pp 
GC. F. Doucette, 2 graduate of the Massachusetts Agricultural College, has 
been appointed scientific assistant and will be assigned to duty at Doylestown, 
Pa., to undertake an investigation of the strawberry rootworm and other 
greenhouse insects. . - A 
C. H. Alden, who has been assisting in connection with apple insect 
investigations at Wallingford, Conn., is spending several.weeks in Washington, 
preparing reports on the subject of his field investigations.

TRUCK-CROP INSECT INVESTIGATIONS ‘ 
F. H. Chittenden, Entomologist in Charge 
During November and December, 1920, questionnaires relative to the 
possible occurrence of the Mexican bean beetle in States-in the South other 
than Alabama were sent out to cotuty agents of southern States as well as to 
entomologists, bean growers, and others who might furnish information in regard 
to the distribution of this pest. In the replies‘received, several new lo- 
calities were reported in the States of Arizona, New Mexico, and Texas, where 
the species was not hitherto known to occur. Four reports of. occurrences 
in Louisiana and one in Arkansas were also received. Those in Louisiana 
have not all been. investigated but in one.case, at least, the beetle con- 
cerned was merely the spotted ladybird (Megilla maculata), one of our most 
beneficial species. In another case the squash ladybird (Bpilachna borealis) 
was the insect under observation, and this. applied also toa reported occurrence 
of the bean beetle in one of the western States.. During January (@. H. Popenoe 
investigated the alleged occurrence of this species at Pine Butt. Ank 2 
with the result that the report was found to be without foundation. The 
results of replies to these questionnaires thus far show that in the southern 
States the insect is not known to occur outside of the area in Alabama, 
consisting of 12 countries, which has already been mapped.
