DOCTOR HOWARD HONORED 
Dr. L. 0. Howard was recently elected an honorary member of the 
Societas Entomologica Cekoslovenica. The Entomological Society of Florida 
has also elected him to honorary membership. Dr. Howard has also re- 
ceived an illuminated address signed by 36 members of the Jugatae, the 
entomological society of Cornell University, congratulating him on his 
long service, inasmuch as he was the first student of entomology to be 
graduated from Cornell. 
TROPICAL AND SUBTROPICAL PLANT INSECT INVESTIGATIONS 
A. C. Baker, Senior Entomologist, in Charge 
F. H. Benjamin collected specimens of Anastrepha ludens Loew 
in a sour orange which he picked from a tree in Matamoros, Tamaulipas, 
opposite Brownsville, Tex., on May 3, 1928. A thorough search during 
the growth of the crop of 1927-1928 failed to reveal any infestation in 
the fruit growing on the Texas side of the lower Rio Grande Valley. 
Dr. S. B. Fracker, in charge of domestic plant quarantines for 
the Federal Horticultural Board, and R. E. McDonald, entomologist for 
the State of Texas, were in Harlingen, Tex., on May 16 to discuss a re- 
vision of the quarantine of the Mexican fruit worm. 
The work of eradicating the Mexican fruit worm in the lower Rio 
Grande Valley of Texas during May was devoted chiefly to the elimination 
of summer host fruits and taking a census of all host fruits. The census 
is to be used as a gauge in planning future operations. The cleanup 
of summer host fruits has been entirely satisfactory, and there is every 
assurance that the host-—free period, March to October, will be thoroughly 
successful. 
P. A. Hoidale, in charge of eradication of the Mexican fruit 
worm, went to Corpus Christi late in May to determine whether a cannery 
there was going to operate a grapefruit preserving plant in the lower 
Rio Grande Valley next season. Adequate canning facilities are needed 
in the valley to dispose of culls and of fruit from possibly quarantined 
orchards. He also visited San Antonio to check up on fruit shipments 
from the valley.
