antine. At the present time Mr. Hadley has charge of the control 
operations and Mr. D. N. Willingmyre the clean-up work. Entomol¬ 
ogists have not yet been assigned for the divisions of quarantine, experi¬ 
mental investigations or parasite introduction work for the coming 
season. 1 
To finance an attempt to eradicate the beetle from New Jersey, 
$15,000 were provided, $10,000 by the federal and $5,000 by the state 
governments. The project thus provided for began in 1918. It was 
thought at the end of 1918 that the probability of extermination was 
slight and that greater emphasis should be placed on control. On the 
basis of the accumulated knowledge and experience, it was planned to 
ask for an appropriation of $35,000 ($25,000 from the federal and 
$10,000 2 from the state governments). 
This amount was granted. After a season’s work and a study of the 
situation the past year (1919) it was decided that the policy of eradica¬ 
tion must be abandoned for reasons which will be given later, but that 
a vigorous policy of control should be inaugurated. Careful estimates 
called for an additional minimum expenditure of $70,000 to prevent 
the further spread of the insect and at the same time discover practical 
control measures and attempt introductions of the natural enemies 
from Japan. Congress appropriated $45,000 of this amount and while 
it will enable us to do a considerable amount of needed and valuable 
work, it is quite insufficient to complete the plans deemed necessary 
for success. Regardless of the fact that the work the past two seasons 
has been carried out in accordance with the best knowledge of the 
insect’s life habits, which were at that time available, the insect has 
enormously increased numerically and has spread at a rather rapid 
rate. 
These details are given that you may understand the plans set forth 
in the following: 
Life History and Habits 
The life history and habits need be treated only briefly to make the 
problem of control understandable. The total life cycle is one year, 3 
most of which time is spent in the soil as an egg, grub, or pupa. Having 
passed the winter in the soil, 2 to 10 or 12 inches below the surface, the 
half to nearly full grown grub returns to near the surface in late March 
1 1 wish to take this opportunity to express my appreciation of the continuous 
support and help given by Doctors Headlee and Quaintance and the valuable assist¬ 
ance of Mr. C. H. Hadley who has always been ready to help on any phase of the 
work. 
2 84,800 was made available previous to July 1, 1919, the remaining $5,200 being 
available for the fiscal year ending July 1, 1920. 
3 The life cycle is identical with that of certain of our Anomolas except that the 
beetles of Popillia are present over a much longer period.
