A decoction of the seed was recommended as an insecticide against 
short-nosed ox louse*— Osbom ( 294 , p* 175) • 
) wao found to poison locusts that fed on it.— Gurney 
(173 , p. 418). 
A sulfuric acid extract < ' the ground seed had a considerable ef- 
fect on fly larvae. — Cook and coworkers ( 104 , p. 14). 
Many reports have been received of the poisonous effect of delphin- 
iums on locusts* In one instance, where the entire crop of other 
owers had been destroyed, fields of delphiniums remained almost unin- 
sd and wherever the locusts had, nibbled these plants they died. —

DELPHINIUM STAPHISAGRIA L. Stavesacre. Lousewort. 
The powdered seeds were used chiefly to destroy lioe on children's 
heeds.— Green ( 169 , v. 1, p. 443). 
Stavesacre was largely used in Europe and wa3 employed both by 
the Greeks and Romans to destroy vermin.—Watt ( 422 , v. 3, p. 64). 
This species was employed in medicine solely as a local application 
for the destruction of lice and the itch mite. — Hare and coworkers ( 183 ) . 
Oil from stavesacre seed was tested as a contact emulsion spray 
ainst many insects, and the results were the same as given for Del - 
phinium consolid a. The alkaloid delphinine of stavesacre seed was tested 
in the form of delphinine hydrochloride dissolved in alcohol, with 
or without soap. At concentrations up to 0.16 percent of alkaloid it 
was inefficient against aphids ( Myzus persioae (Sulz.)), mealybugs, 
! spiders, and thrips, and did not prevent fall webworms from feeding 
normally* A 0*085-percent solution was of value against the onion 
thrips. It was also effective as a stomach poison against cabbage 
worms*— Davidson ( 113 ) . 
Extracts were not repellent to the Japanese beetle*— Met zger and 
Grant (277)*
