TThen it is not feasible to fumigate with hydrocyanic acid gas, 
persistent dusting with 5 percent nicotine sulphate dust is recommended

Lights placed over shallow pans of oil as trap for the adults 
of the greenhouse leaf tyer (Phlyc taenia rubigalis Gn. ) are also of

with nicotine, the fumes of which irritate the moths so that they all 
take flight and are more easily attracted to the lights (p. 404) .
