Dean (G. A.), Kelly (E. G.) & Ford (A. L.)- Grasshopper Control in 

 Kansas. — Jl. Econ. Entom., Concord, N.H., sii, no. 2, April 1919, 

 pp. 213-217, 1 plate. 



A campaign organised to protect the country in the summer and 

 autumn of 1918 from a threatened serious outbreak of grasshoppers 

 is described. The methods adopted included personal visits to the 

 farms and demonstration meetings. At each demonstration the 

 life-history of the grasshopper was explained and bran mash was 

 mixed and distributed with a device for sowing it. In some districts 

 the ingredients for it were supplied from county funds ; in others 

 the farmers bought them themselves. The results were very successful 

 in nearly every case. The presence of a large number of eggs of 

 Melanojjlus atlantis warranted a second campaign in the autumn to 

 protect the wheat crop. It was carried out on similar lines and it 

 was also decided to combine poisoning and autumn disking to destroy 

 the eggs. 



The campaign proved a complete success. The value of co-operation 

 was emphasised as much as possible, and many townships decided 

 to carry on the disking as a unit, a special day being set aside 

 for the purpose.

In addition to the uses of insect galls, already recorded [see this 

 Review, Ser. A, vi, p. 244], those produced on Rhus glabra by an 

 undetermined mite, a species of Eriophyes, are stated to be used 

 by the Chippewa Indians in the form of an infusion as a remedy for 

 diarrhoea. This mite is the cause of stunted heads and curled leaves 

 in the food-plant, and is very common in Minnesota.

Pyrausta nubilalis, Hb., was found in Connecticut in March. Its 

 limits have not yet been ascertained, but prompt measures are being 

 taken to suppress it.

It is now stated that the beetle found feeding on Azalea [see this 

 Review, Ser. A, vii, p. 37] is Galerucella rufosanguinea, Say, and not

In the course of some experiments for the control of Phorbia 

 brassicae, Bch., treatment with green tar oil proved the most efiective. 

 Anthracene oil was mixed at the rate of 1 part to 80 parts of soil and 

 scattered as a protecting collar round the base of the plant as soon 

 as it was transplanted. A weaker mixture would probably suffice,
