8 SOME INSECTS INJURIOUS TO TRUCK CROPS. 
the Oakley occurrence was the first that Mr. Smith had noted since. 
In most of the asparagus acreage of the State the insect was not yet 
present. 
Mr. Franklin Sherman, jr., has kept a careful record of the occur- 
rence of this species in North Carolina, and informed the writer, on 
the occasion of a visit in 1906, that it is common in the east-central 
part of the State in the trucking belt, and especially abundant at 
Raleigh, Wake County, Goldsboro, Wayne County, and Warsaw, 
Duplin County. 
In order to make the present account of the known distribution of 
this species as complete as possible, inquiry was made of the official 
entomologists of the States of Kentucky, Iowa, Missouri, Nebraska, 
and Minnesota, all of whom reported that the occurrence of this spe- 
cies in their States had not been brought to their attention. Mr. James 
G. Moore, however, assistant in horticulture at the University of Wis- 
consin, Madison, Wis., stated that the asparagus beetle had been found 
in Wisconsin, but he had no special data on its distribution. 
REMEDIES. 
With regard to remedies good results have followed the experimental 
use of arsenate of lead. This insecticide has come into very general 
favor in recent years, and in the correspondence of this office we have 
for sometime advised its employment against most leaf -feeding beetles, 
like the asparagus beetles. In Connecticut Dr. W . E. Britton a has made 
a practical test of this remed} T on asparagus plants, spraying them from 
all four sides in succession because of the slight leaf exposure as com- 
pared with most other plants. The day following treatment (June 4) 
many dead beetles and larvae were found on and under the plants. A 
few had survived and were feeding, but ten days later only a few 
living larvse could be found, and the beetles did not again become 
abundant on the plants during the summer. The same amount of 
good might be accomplished with scarcely greater expense by spray- 
ing from opposite sides and repeating just before the time for the last 
generation to develop and in time to check the beetles before they go 
into winter quarters. 
In Pennsylvania Prof. H. A. Surface, 6 in a series of experiments 
with Paris green and arsenate of lead, applied to asparagus plants the 
first week of June, 1905, found that not more than 50 per cent of the 
insects were killed when Paris green and lime were used. With lead 
arsenate 90 per cent were killed, while in one experiment, by the addi- 
tion of resin soap, which is used as an addition to an insecticide to 
a Kept. Conn. Agric. Exp. Sta. f. 1903 (1904), pp. 275, 276.
