Univ. Agric. Expt. Sta., La Fayette, Ind., Circ. no. 64, July 1917, 

 15 pp., 9 figs. [Received 21st March 1918.] 



As its name indicates, this bulletin deals with the common insect 

 pests of cabbage, cucurbits, onions, potatoes, maize and tomato and 

 recommends the usual contact and poison insecticides.

 Indiana.^ — Purdue Univ. Agric. Expt. Sta., La Fayette. Ind., Circ, 

 no. 65, August 1917, 14 pp., 8 figs. [Received 21st March 1918.] 



Mint is not usually damaged by insects, though in some seasons 

 cutworms and grasshoppers may become serious pests. They may 

 both be controlled by means of a poisoned bait composed of 50 lb. 

 wheat bran, 2 lb. Paris green, 6 finely .chopped oranges or lemons 

 and enough cheap molasses and a little water to bring the mixture 

 to the consistency of a stifi dough. As cutworms feed during the 

 night, and grasshoppers in the morning, the bait should be distributed 

 broadcast in small lumps during the evening.

As a preventive measure against the attacks of insects and diseases, it 

 is advisable to spray a young orchard during the first part of May and 

 again at the begiiming of July with a mixture of 1 U.S. gal. concen- 

 trated lime sulphur solution (32° Be.) to 40 U.S. gals, water, 1 lb. of 

 lead arsenate powder or 2 lb. paste, being added to every 50 U.S. 

 gals, of spray solution. 



In the event of the appearance of the San Jose scale {Aspidiotus 

 perniciosus), tlie orchard should be given a dormant spray in spring 

 of 1 U.S. gal. concentrated lime-sulphur solution to 7| U.S. gals, water. 



Reed (H. J.) & Woodbury (C. G.). Melon Growing in Indiana. — 

 Purdue Univ. Agric. Expt. Sta., La Fayette, Ind., Circ. no. 68, 

 August 1917, 16 pp., 14 figs. [Received 21st March 1918.] 



The chief insects damaging melons are the striped beetle [Diabrotica 

 vittata], which attacks the young plants as soon as they appear above 

 ground, and the melon aphis [Aphis gossypii], which feeds on the 

 under-surface of the leaves, causing them to curl. The former can 

 be controlled by a mixture of 2 parts air-slaked lime and 1 part tobacco 

 dust. Another mixture that may be sifted over each hill in sanall 

 quantities consists of land plaster (finely ground gypsum) or sifted ashes, 

 to which a small quantity of turpentine (4 oz. to a peck of ashes) 

 has been added. No successful method of dealing with, this pest on 

 a large scale has yet been devised. 



Aphis gossypii has been successfully dealt with by spraying the 

 under-side of the leaves with a dilute nicotine solution, using 1 part 

 40 per cent, nicotine sulphate solution to 800 parts water, which is 

 about equivalent to 1 pint to 100 gals, water.
