Phalonia ambiguella CHbn. ) 
See Paillot ( 323 ) under Polychrosis botrana, on page 60. 
Gessner (157) in 1929 reported tests in Germany with a Korean prepa- 
ration [Neoton?] from the roots of Derris elliptica at a concentration of 
100 gm. per 45 liters of water, to which was added 100 gm. of cottonseed 
oil plus soft soap. Before it was used the spray material was allowed to 
stand for 2 hours, with repeated stirring. This spray was ineffective in 
combating the pupae of ( Conchylis ) Phalonia ambiguella and the larvae of 
(C. ) Phalonia roser&na , Nicotine caused high mortality. 
Jancke and Roesler ( 220 ) in 1939 reported the results of laboratory 
experiments carried out in the Rhineland in February-April 1939, in which 
pupae of the vine moths ( Clysia ) Phalonia ambiguella and Polychrosis 
botrana (Schiff.) in trap bands of corrugated cardboard were left in posi- 
tion on small sections of the card and sprayed with various mixtures. An 
insecticide should give at least 95-percent mortality to be effective, but 
this percentage was not given by a 5-percent emulsion of tar distillate 
alone or with 0.2 percent of nicotine, 1 percent of a preparation of pyre- 
thrum, or 1 percent of derris ; by a proprietary winter-oil spray; or by 
nine mineral oils in various combinations with nicotine, pyrethrum, or 
derris. Field tests with the mixtures were carried out in several local- 
ities in the Rhineland, but no satisfactory mortality was obtained, as 
measured by the numbers of adults subsequently caught in trap glasses. 
Phalonia sp. 
Frydlender ( 148 ) in 1933 wrote that insecticides derived from derris 
have been on the French market for several years. The Association Viticole 
Champenoise, "deceived by pyrethrum soap, have had recourse to Katakilla, 
an English product made from derris, to ccmbat tho 'Cochylis* (vine moth)." 
Phycitidae 
Citripestis saglttiferella (Moore) 
Pagden ( 322 ) in 1931 wrote that derris and haiari may be used as 
stomach poisons for the control of this species on citrus. 
Ephestia cautell a (V.'alk.), the almond moth 
Craufurd-Benson (85) in 1938 reported that the larva was not suscep- 
tible to a derris insecticide when dipped in it, 
Ephestia elutella (Kbn.), the tobacco moth 
Resistant to derris powder. -- Anonymous (5) la 1937. 
Craufurd-Benson (85) in 1938 reported bhat a derris insecticide had 
very slight effect on the larva when tested by dipping.
