The parasite Pteyomaliisgelechiae, Webster, and the mite, Pediculoides 

 vcntricosns, Newp., kill a certain number of this moth, but cannot 

 be depended on as a means of control either in the field or in storage. 



Reeves (G. I.), Chamberun (T. R.) & Pack (K. M.)- Spraying for 



the Alfalfa Weevil.— C/.S. Dept. Agric, Washington, D.C., 



Farmers' Bull. 1185, December 1920, 20 pp., 9 figs. [Received 



20th April 1921.] 



The method of spraying lucerne with arsenicals against the alfalfa 



weevil {Hypera variabilis) here described is the result of seven years' 



study and experiment and one season of field trial, in the course of 



which over 4,000 acres were successfully treated. The feeding larvae 



are most numerous about one to two weeks before the first crop is 



ready for cutting, and this has proved the best moment for spraying, 



the date depending on weather conditions. The treatment described 



can be used for both large and small acreages in most of the territory 



of Utah, Idaho, Colorado and Wyoming.

In view of the establishment of Platyedra {Gelechia) gossypiclla in 

 Montserrat and St. Kitts [R.A.E., A, ix, 99], the danger of its 

 spread to Guadeloupe and Martinique is imminent, and the necessity 

 for the application of vigorous preventive measures is emphasised.

The coffee pests recorded for 1919 are Stephanoderes sp., Coccids, 

 Aphids and red ants. In May 1920 a serious attack of borers was 

 noticed, the species involved being a Longicorn, Tragocephala anselli, 

 and a Bostrychid, Apate monacha. These beetles may be destroyed 

 by injecting a solution of carbon bisulphide into the galleries.

Colaspidema atriini, while usually injurious in lucerne fields, occa- 

 sionally does considerable damage in gardens and vegetable plots, 

 showing a preference for the outer flowers of the marguerite, leaves 

 of beans and parsley, potato leaves being less severely attacked. 

 These infestations apparently onty occur when there is a shortage 

 of the normal food supply of the beetle.
