Spraying, under pressure, with a mixture of commercial lime-sulphur 

 solution, 1 U.S. gal. to 8 U.S. gals, water, with 1 lb. lead arsenate 

 paste (or | lb. powdered lead arsenate) and a little extra lime to make 

 a thin coating, though not a complete remedy in itself, reduces the 

 number of borers, and thus greatly lessens the laborious task of 

 worming. 



Brood of 17-year Locusts to appear next Spring. — Mthly. Bull. Ohio 

 Agric. Expt. Sta., Wooster, ii, no. 2, February 1917, p. 66. 

 [Received 19th June 1917.] 



A brood of the periodical cicada [Tibicen septemdecim] was expected 

 to appear in the eastern part of Ohio during the spring of 1917, and a 

 large brood is expected over the western part of the State in 1919. 

 In the latter district fruit trees should not be planted extensively in 

 the spring of 1918. Young trees should have the trunks and large 

 limbs wrapped with paper to prevent oviposition, and the upper limbs 

 should then be enclosed in mosquito netting as a complete protection, 

 or sprayed with Bordeaux mixture or lime-sulphur wash as a partial 

 protection ; these measures are much more effective than attempts 

 to kill the insects themselves.

The most common and destructive cutworms in Ohio are Sidemia 

 (Hadcna) devastairix (glassy cutworm), Pdrnstichti.s (//.) ardica [jqWow- 

 headed cutworm), Agrotis ypsilon (greasy cutworm), Lycopholia {Peri- 

 droma) margaritosa (variegated cutworm), Agrotis {Noctua) c-nigrum 

 (spotted cutworm), Feltia subgothica (dingy cutworm), F. acidifera 

 (western striped cutworm), F. gladiaria (clay-backed cutworm), 

 Nephelodes emmedonia {minians) (bronze cutworm), Agrol:>i unicolor 

 {Noctua clandestina) (W-marked cutw^orm), Feltia amiexd (granulated 

 cutworm), Euxoa messoria (dark-sided cutworm), E. ochrogaster 

 (common striped cutworm), and Polia (Mamestra) renigera (bristly 

 cutworm). 



Their natural enemies are nearly all ground-frequenting birds, such 

 as robins, blackbirds, bluebirds, crows and domestic poultry, which all 

 feed greedily on them, while toads, skunks and shrews devour them 

 whenever possible. Their commonest and most eiTective enemies are 

 parasitic flesh-flies, which lay their eggs just behind the head of t!ie 

 cutworm. They are also preyed upon by ground-beetles and t'ger 

 beetles and their larvae and by digger wasps, and other insects. 



Since the eggs are laid among rank-growing, succulent herbage, the 

 best method for preventing damage over large areas is to plough early 

 in the autumn and keep down weeds by frequent harrowing. Poisoned! 

 cereal bait may be used in spring before planting a crop in a recently 

 ploughed badly-infested field. This is made of 25-35 lb. of wheat 

 bran thoroughly mixed while dry with | lb. of Paris green, or lead 

 arsenate, or powdered w^hite arsenic. This mixture is then made into a 

 paste with 1 U.S. quart of any cheap syrup in 2 or 3 U.S. gals, of water, 

 with the addition of 6 finely minced oranges or lemons. The bait 

 should be scattered over the land in little heaps, being more readily
