Flowering trees were sprayed with water then dusted with 
powdered tobacco to protect them against the attacks of Epicometic 
(Tropinota) .

Nicotine sulphate sprays with soap are "briefly described (pp» . 
10-11) and recommended for the following insects: Various plant lice 
and onion thrips (p. 19), tarnished plant bug (Lygus pratensis) 
(p. 20), bean aphid (p. 29), harlequin cabbage bug ( Murga n tia 
histrionica) (p. 34) , plant lice (p. 35) , and melon aphid (Aphis

Nicotine sulphate was recommended as a control for six- species 
of aphids ( Macrosiphum solanif oli i , Aphi s brassica e, A. gossypii , A. 
rumicis , Acy r tho sipho n pisi , and Rhopalosiphum persicae ) , and for 
the onion thrips ( Th rip s t abaci) . It killed 65 to 75 percent of 
the nymphs and 40 to 50 percent of the adults of the harlequin cab- 
bage bug ( Murgantia h istrion ica) . It also killed the nymphs of the 
squash bug ( Anasa tristis ) . Tobacco dust was used as a deterrent 
against cucumber beetles ( Diabrotica vittata ) , the red spider ( Tetranychus 
sp.), and springtails ( Smynthurus ) .

The cabbage root-maggot (C hortophila f usciceps ) is best dealt 
with by placing some repellent, such as tobacco dust about the 
roots of young plants. The tarnished plant bug (Lygus pratensis ) 
and false chinch bug (Nysius angustatu s N are controlled by strong 
tobacco extract and soap. The garden flea hopper ( Hrltica u hleri ) 
can. be controlled by tobacco extract. Thr ips tabaci is easily 
controlled by tobacco extract and whale-oil soap. Watermelons 
are infested by Aphis gossypii , for which the suggested controls 
are spraying with Black Leaf 40 and soap solution, fumigating with 
tobacco, or dusting with tobacco dust when the young plants are wet 
with dew, and clean culture.
