Bouhelier (4l) in 1940 reported on the control of this species on var- 
ious cultivated plants in Morocco, Since the use of arsenicals on market- 
garden crops is prohibited, sprays containing derris extract, nicotine, or 
nicotine sulfate were tested on infested tomatoes, but the results v. r ere 
unsatisfactory. 
Haines tra olerac eae (L. ) 
An anonymous writer (5_) in 1937 wrote that this species has been ef- 
fectively checked with a concentration of 0.75 percent of rotenone. 
Naranga aenescens (Moore) 
The Institute of Physical and Chemical Research ( 214 ) Tokyo, Japan, 
in 1927 reported that Neoton at the rate of 1 pound in 40 imperial gallons 
of water, sprayed on the eggs soon after cviposition and kept from rain, 
gave a mortality of 4,6 percent. 
Nephelodes emmedonia (Cram.), the bronzed cutworm 
Kelsall and Stultz ( 234 ) in 1937 reported that derris-gypsum dust 
(0.4 percent rotenone) killed 21 percent in 2 days. After 2 weeks a con- 
siderable number of derris-treated caterpillars were still alive. These 
cutworms were collected in the field and treated in the laboratory. 
Ophiusa mcli cert a Drury 
The larvae are remarkably sensitive to derris powder. A dust contain- 
ing 0.5 percent of rotenone was completely effective against almost full- 
grown larvae. — Van der Vecht (454) in 1936, 
Fanolis flammea (Schiff.) 
We is ( 477 ) in 1931 reported that third instars were very sensitive to 
Polvo; 0.09 rag. per caterpillar was fatal in 2 to 3 days. Fourth ir.stars 
were moro rosistant. Dusting of mouth parts had no result bocause the 
large particles adhered poorly and fell off. Polvo possessed ropellont 
properties against tho second instars and most of the fourth instarc. 
Sohwerdtfogor ( 566 ) in 1932 roported experiments on the control of 
this specioc vdth several proprietary insocticides, including ono emulsion 
(Dorrothan) and two powders (Dorrothan I and Derrothan II ) containing der- 
ris or extracts thereof. Tho powders, : ..^tcd at 50 kg. per her r . eausod 
100-porcont mortality in 24 hours; and the emulsion also was very effective, 
Panolis ftrisoovaricgata (Goozo) 
Tragardh ( 416 ) in 1935 reported that the principal forest lepidopter- 
ous insects in Europe dusted with arsenicals or oljher insecticides duri' 
1925 to 1934 are, in decreasing extent: P anel j- r : rii gata , j us
