SPRING NUMBER 57 
record for large attendance of members and visitors. Much of 
the program was devoted to experimental work on insecticides. 
Some of the large insect problems were presented and discussed. 
However nothing was said about the boll weevil. A feature of the 
meeting was an exhibit of the Gypsy Moth and the European 
Corn Borer displayed by the U. S. Bureau of Entomology.—A. H.

DELPHASTUS AT BRADENTOWN 
A recent trip to Bradentawn afforded an opportunity to visit 
the citrus grove in which the California Delphastus was liberated 
in 1917 and where they have been most successful in controlling 
the whitefly. In only one small section of the grove was there 
enough whitefly to perceptibly blacken the trees and there the 
Delphastus was found. Were it not for the purple scale and rust 
mite this grove would not have needed spraying for the past five 
years. But in order to control the scale the grove has been 
sprayed about once a year. There were some signs of the En- 
tomogenous fungi and undoubtedly the annual sprayings have 
also contributed to the control of the whitefly, and incidentally 
killed many of the beetles, but it would appear as if the Delphas- 
tus has been the major factor in the commercial control of the 
whitefly during the past five years. Indeed from the standpoint 
of their spread over the state they have been too successful. 
They have reduced their food to such a degree that they them- 
selves are too scarce to make their collection practicable. The 
lady beetles have been pretty well distributed over the state but 
no systematic effort has been made to follow up these introduc- 
tions and determine whether the beetles have established them- 
selves. They are so small and quick to drop at the least jar that 
no one without experience with them would be likely to find them 
unless they were very abundant. In a grove at Crescent City 
they were much in evidence one summer but seemed to diminish 
in numbers during the winter. It is possible that they are better 
adapted to the southern part of the state. 
A NEW MEALY BUG PREDATOR FOR FLORIDA 
The Department of Entomology of the Experiment Station 
has received the first of several shipments of the lady beetle 
Scymnus binaeratus, which has done good work in controlling 
all species of mealy bugs in California. An effort will be made
