Archips rosaceana (Harr. ), the oblique-banded leaf roller 
In the Netherlands derris at a dilution of 1:5,000 was used with good 
results against ( Cacoecia ) Archips rosaceana . — Anonymous (_5_) in 1937. 
Carposina sasakii Mats, , 
Toyoshima ( 415 ) in 1934 reported that spraying apples with nicotine 
.sulfate, or derris, killed many of the eggs. 
Sprays of lead arsenate, derris, or nicotine sulfate have not proved 
effective for control. — Yago and Ishikawa ( 503 ) in 1936.

Spar gano this sulfureana (Clem,) 
commonly 
Beckwith (31) reported in 1938 on the control of this species, /known 
as the false yellowhead or sulfur leaf roller. Cage tests- carried on in 
the Doehlert apparatus indicated that the adults could be killed by an 
application of 50 pounds of pyrethrum dust (0,9 percent pyrethrins) to the 
acre but, because of the irregularity of emergence, this treatment was not 
considered practical under ordinary conditions. An airplane application 
of 15 pounds of derris dust (4 percent rotenone) to the acre was not effec- 
tive in killing larvae in a single field experiment. 
The New Jersey Agricultural Experiment Station ( 294 ) in 1938 stated 
derris dust (4 percent rotenone), applied at the rate of 15 pounds per 
acre from an airplane, was not effective in killing this insect. 
Acleris contaminana (Hbn. ) 
A product containing 12 percent of powdered Lonchocarpus nicou root 
(6 percent rotenone) and 88 percent of talcum killed "Terras contaminata " 
on rose and pear, according to Etablissements Rotenia in a letter to 
R. C. Roark in 1938,

Derris with sulfite-lye failed to wet and spread well on the foliage 
but the addition of lime-sulfur improved the mixture in this respect. 
Neither nicotine nor derris greatly reduced the proportion of fruits bit- 
ten by caterpillars of Tortrix sp. — East Mailing Research Station ( 10 5) 
in 1934.
