in the opinion of the author, the period between the applications could 

 be lengthened to 5 days. This treatment is profitable where maize 

 is grown for roasting ears, show purposes or seed.

 no. 2, pp. 214-218, 2 plates. 

 The corn-ear worm [Chloridea obsoleta, F.] feeds on maize, cotton, 

 beans, peas, etc. The number of broods a year in Missouri has not 

 yet been determined. Eggs are deposited on the maize silks, and 

 oviposition occupies several days. The larvae, which hatch in about 

 3 days, feed at first on the silks, then pass down to the grains. Other 

 eggs are deposited later on the tips of the ears. The average length 

 of the larval period is 18| days. Pupation occurs in the soil at a depth 

 of from 1-3 inches. The adult emerges after 7-18 days, is very active 

 and feeds on the juices of flowers and fruit. The length of the hfe of 

 the adult is probably about 5 days. The actual damage caused by the 

 worm is increased by fungus growths which invariably follow. 

 A discussion on the use of lead arsenate, hydrate of hme and sulphur 

 as dusting powders followed the paper.

 Fruit Juice as a Means of controlling some Insects. — Jl. Econ.

The use of poisoned bait in the control of grasshoppers, army worms, 

 variegated cutworms, etc., has had very successful results. During 

 1914, several severe local infestations of grasshoppers were reported. 

 Lucerne and wheat crops were saved from injury by scattering the 

 bran mash along the edge of the field into which the insects were moving. 

 Very serious outbreaks of Cirphis (Leucania) unipuncta, the army 

 worm, and Lycopliotia margaritosa {Peridroma saucia), the variegated 

 cutworm, were controlled in a similar way. Gryllus pennsylvanicus 

 was very abundant in Kansas during the summer of 1914. A poisoned 

 mash consisting of 1 lb. bran, 1 oz. Paris green, 3 oz. syrup, juice of 

 orange or lemon, and 1| pts. water, proved very effective. The bait 

 distributed in the evening. In the discussion which followed the 

 paper, the author stated that the insects preferred the bait to the 

 crop they attacked. There had been no report of injury to birds or 

 bees. Those cases among birds in which death had occurred, were due 

 to eating too many grasshoppers. Mr. Regan stated that, in 

 Massachusetts, barriers had successfully retarded the migration of the 

 army worm, the barriers being ploughed furrows dusted with slaked 

 lime, poisoned bran mash and road oil. In New Jersey, the use of 

 shallow ditches was more effective than poison bait in protecting 

 lawns ; gasoline was used to destroy the worms collected in the 

 ditches.
