are soon attracted and the poison takes effect while they are sipping 
it. The flies must then he destroyed or they will revive in the course 
of 24 hours.— Elliott ( 129 , v. 1, p. 421). 
The powdered bulbs and leaves used as dusts were efficient but slow 
against cockroaches, grasshoppers, flies, and bees, but inefficient 
against aphids and tent caterpillars. As a stomach poison these powders 
were efficient against grasshoppers, silkworms, and flies, out had no 
effect on large webworms. The water extracts from the leaves and bulbs, 
used as sprays, had considerable effect on cockroaches, potato beetle 
larvae, and silkworms, but none on webworms and aphids. Apple trees 
bearing tent caterpillars were sprayed with 10-percent solutions of water 
extracts from the leaves and bulbs. A week later the caterpillars were 
shrunken and had not eaten the sprayed leaves.— Mclndoo and Sievers 
(259 , pp. 5-6). 
ASPARAGUS OFFICINALIS L. Asparagus. 
In laboratory tests asparagin used as a dust had no effect on 
codling moth larvae.— McAlister and Van Leeuwen ( 24 9) . 
COLCHICUM AUTUMNALE L. Meadow saffron. 
A decoction made from the seeds or roots with vinegar or alcohol 
was recommended against aphids on rose bushes.— Binnenthal (57, pp. 45, 
46). 
Tincture of colchicum mixed with honey had no effect on ants 
(Lasius emarginatus (Oliv.)).— Cobelli ( lOO ). 
An extract of meadow saffron contains the poisonous alkaloid 
colchicine, the solution of which is facilitated by the addition of 
alcohol; molasses may be added to the liquid to make it adhesive.—

Tuber colohici (100 and 10 percent in flour) was fed to caterpillars 
of Prodenia litura (F.). Those fed 100-percent tuber did not eat while 
those fed 10- per cent tuber ate slightly and a few died.— DeBussy (76) • 
Extracts were not repellent to the Japanese beetle. — Metrger and 
Grant (277). 
Extracts applied as sprays against adult mosquitoes were muoh 
inferior to the standard mosquitocide. — Wats and Singh ( 421 ) • 
CONVALLARIA MAJALIS L. Lily-of-the-valley. 
Extracts were not repellent to the Japanese beetle.--Metiger and 
Grant (277).
