60 EXPERIRIENT STATION RECORD. [Vol.41 



Fight the chinch bug with crops, W. L. Buelison and W. P. Flint {Univ. 

 III., Col. Agr. Ext. Circ. 30 (1919), pp. U, figs. 7). — ^A discussion of the crops 

 which may be grown in combating the chinch bug. 



The oriental fruit moth in Virginia, L. A. Steaens {Quart. Bui. Va. State 

 Crop Pest Corn., 1 {1919), No. 1, pp. 3-7, figs. 5). — A thorough inspection of 

 Alexandria and Fairfax Counties indicates that Laspeyresia molesta has be- 

 come generally established in home orchards south and west of the Potomac 

 Kiver to a line drawn through the points Great Falls, Herndon, Fairfax, Annan- 

 dale, and Alexandria. A similar inspection of Loudoun County located an " out- 

 post " of infestation in a single commercial orchard at Leesburg. Both twigs 

 and fruits showing suspicious typical injury have been collected in orcliards 

 along the railway from Leesburg to Bluemont. 



The European corn borer (Pyrausta nubilalis), E. P. Fbilt (A'^. T. State Col. 

 Agr., Cornell Ext. Bui. 31 {1919), pp. 35-42, pis. 2, figs. 5). — A popular summary 

 of information on this pest which has appeared in New York State in the 

 vicinity of Scotia. The infestation covers about 400 square miles, extending 

 west to Fort Hunter and east of Schenectady. 



The sugar cane moth borer, T. E. Hollowat and U. C. Loftin {U. S. Dept. 

 Agr. Bill. 746 {1919), pp. 74, pls. 10, figs. 12).— This is a report of the present 

 status of knowledge of Diatrcea saccharalis crambidoides, based upon a review 

 of the literature and investigations conducted by the authors over a period of 

 years, together with technical descriptions of the larva and pupa stages by C. 

 Heinrich. 



It is shown that this form occurs in Florida as far north as Gainesville, in 

 southwestern Mississippi, in southern Louisiana, and in the Rio Grande Val- 

 ley in Texas in the vicinity of Bro\^Tisville. 



Its only parasite of importance in the United States is Trichogramma mi- 

 nuta, which attacks the egg and is universally distributed in the sugar-cane 

 tields of Louisiana and also in the Rio Grande Valley in Texas. Mention is 

 made of a number of natural enemies which occur in foreign countries, includ- 

 ing a Cuban tachinid {Exizenilliopsis diatrcece), introductions of which are be- 

 ing made into Louisiana. Experiments and observations on artificial control, 

 which are presented in detail, have led to the following recommendations: 



•• Scraps of cane left about the factories and derricks, after the grinding season, 

 should be destroyed by burning or otherwise. Cars in which cane is shipped, 

 especially if they go into noninfested territory, should be kept free of such 

 scraps. Seed cane should be planted in the fall, if possible, and kept as deeply 

 covered as practicable. Extraordinarily deep planting is not advocated, but as 

 borer moths fail to emerge from cane under more than 0.5 in. of compact soil, 

 care should be taken to keep the seed cane well covered to that depth as a 

 minimum. A heavy rain will sometimes wash the earth from the seed cane 

 from one end of the row to the other, and in this case it is important to cover 

 the cane again as soon as possible, especially in the spring, when the moths 

 are emerging. 



" Cane for shipment to points beyond the infested area should be selected 

 so as to obtain it sound and free of borers, or, if this is impo-ssible, it should be 

 soaked, previous to shipment, for at least an hour in Bordeaux mixture or a 

 solution of nicotin sulphate. 



"The 'trash,' leaves, or 'shucks' left on the fields after cutting should not 

 be burned, but should be lightly covered with earth in the fall and plowed 

 out in the spring. This practice has never been found to increase the borer 

 infestation, and it has often diminished it. The soil is fertilized by the buried
