to 100 co, of liquid, as compared with 0.009 gm. for nicotine sul- 
fate.— Riohar da on and Smith ( 522 ). 
Morphine sulfate (0.005 pound per 50 gallons of water) was tested 
in a spray against the Japanese beetle. In one test none were killed 
within 6 days, but in a second test 20 peroent were killed. — ilo ore 
and Campbell (264 , p. 400). 
Narootine was found to be of no value against the bean aphid. It 
was not materially toxic at or below a concentration of 1 gnu per 
100 oc. of liquid.—Tattersfield and coworkers (393 ). 
Comments by reviewer .— It is surprising that the opium alkaloids 
are not more toxic to inseots. More work should be done with them. 
SANGUINARIA CANADENSIS L. Bloodroot. 
Extracts of the root killed only 35 percent of the mosquito larvae 
tested.— Hartzell and Wilcoxon ( 188 ) . 
PASSIFLORACEAE 
(Passionflower Family) 
PASSI FLORA INCARNATA L. Passionflower. 
Extracts were not repellent to the Japanese beetle.— Metsger and 
Grant (277). 
Extracts of the whole plant killed only 5 peroent of the mosquito 
larvae tested.— Hart sell and TfiLlcoxon ( 188 ). 
PEDALIACEAE 
CERATOTHECA INTBGRIBRACTEATA Engl. 
A decoction was used in West Africa as an insecticide.— Greshoff 
( 171 , p. 145). 
SESAMDM INDICUM L. Synonym: S. orientalis L. Sesame. 
Stored grain was coated with sesame oil and kept in closed re- 
ceptacles. The oil retarded attacks of weevils ( Calandra ) Sitophilus 
oryza (L.) as long as the grain remained moist, but the grain was 
attacked after a few months. — Fletcher and Ghosh ( 140 , pp. 733-755). 
An insecticide consisting of pyrethrins or rotenone, with sesame 
oil added as a synergist, is described in a patent. The concentration 
of the insecticide required to cause 100 percent mortality of house- 
flies was reduced, and the paralysis of the insects not hit with suf- 
ficient insecticide actually to kill ^s prolonged. —Earleson (125) .
