SABBATIA ANGULARIS (L.) Pursh. * Rose gentian. 
Extracts were not repellent to the Japanese beetle.—Metiger and 
Grant (277), 
SWERTIA CHIRATA Buch.-Ham. 
Extracts applied as sprays against adult mosquitoes were much 
inferior to the standard mosquitocide.— Wats and Singh ( 421 ) . 
SWERTIA CHIRAYITA (Roxb.) Lyons. Chiretta. 
Extracts were repellent to the Japanese beetle. — Mettger and 
Grant (277). 
GERANIACEAE 
(Geranium Family) 
GERANIUM CAROLINIANUM L. Cranebill geranium. 
Extracts were not repellent to the Japtnese beetle.— Mettger and 
Grant (277). 
GERANIUM MACULATUM L. Wild geranium. 
Extraots of the roots killed 20 percent of the mosquito larvae 
tested.— Hartsell and Wllcoxon, ( 188 ). 
PELARGONIUM ODORATISSIMUM (L.) L»Her£t. 
Aroma-rosa, which Is probably this species, was used in Venezuela 
for killing insects. — Roark ( 332 , p. 4). 
PELARGONIUM spp. Geraniums. 
Rose geranium oil was considered one of the best repellents against 
the screwworm.— Parman and coworkers (302). 
The feeding of Japanese beetles on cultivated geraniums caused 
paralysis, and about 35 percent of them died within 4 days. The flowers 
appeared to be more attractive and more toxic than the foliage.— 
Ballou ( 49 , p. 293). 
The essential oil from geraniums was applied as emulsion sprays 
in Russia against the oomraon red spider and the cotton aphid. A 
2-peroent concentration killed from 51 to 80 percent of them.--

PELARGONIUM ZONALE Willd. Horseshoe geranium. 
Extraots of the leaves and stems killed none of the mosquito larvae
