92 species as occnrring in the Santa Cruz Peninsula, of which 5 are described

Note on the Indian peach aphis (Anuraphis helichrysi Kalt. )« A. C. 

 Bakee (Mo. Bui. Dept. Agr. Calif., 9 (1920), No. 5-6, p. 203).— This aphis is now 

 known to occur from Washington State south to California and across into 

 Colorado. While found during the past two years on one or more of its summer 

 hosts, various weeds of the family Compositse, recent collections are said to 

 have been received from plum trees in the north Pacific region. It has been 

 reported by Das to be very destructive to peaches in northern India. 



Experimental investigation of louse control, A. Hase (Ztschr. Hyg. u. 

 Infektioiiskrank., 81 (1916), No. 2, pp. Si 9-378). — This paper includes a bibliog- 

 raphy of 11 pages. 



The use of corn as a trap crop for the cotton bollworm, A. W. Moebxll 

 (Aris. Agr. Col. Ext. Circ. SO (1920), pp. 3-10, Jigs. 3). — In the present account 

 the author presents information on the trap crop method of bollworm control, 

 which is the only method the practicability and effectiveness of which in 

 Arizona has thus far been demonstrated. 



The use of corn as a trap crop for the cotton bollworm in Arizona was tested 

 in 1914 by H. B. Atha in an Egyptian cotton field near Glendale, the results 

 being strikingly successful. Rows of corn planted in May at intervals of about 

 300 ft. through a field of Egyptian cotton gave practically perfect protection to 

 the cotton. Observations made in southern Arizona indicate that corn produc- 

 ing fresh silks through the month of June and half of July is not detrimental 

 to near-by cotton and may be a great benefit to the cotton crop in a near-by 

 field. It is recommended that the time of first planting of corn be advanced in 

 Arizona so that it will be in silk during the month of July as well as August. 



The sugar cane borer and its control, R. S. Kasahgode (Dept. Agr. Bom- 

 bay Bui. 94 (1919), pp. [2] +10, pis. 3). — This paper on the sugar cane borer 

 of western India deals in the main with Diatrcea auricilia. 



Report of the spruce budworm, M. W. Blackman ([Atigusta] : Maine 

 Forestry Dept., 1919, pp. 10). — This is a brief account of Tortrix fumiferana 

 Clemens, the most serious pest of spruce, fir, and hemlock in Maine, based upon 

 investigations by the author including a week in the forests of Piscataquis 

 County, several days in the Rangeley Lake region, and a week in observation 

 in the coast region from Bangor to Kittery Point. A bulletin on this insect 

 from the Maine Experiment Station by Johannsen has been noted (E. S. R., 29, 

 p. 255). 



The outbreak which has taken place since 1911 is a much more serious and 

 destructive one than that which occurred 30 years ago, as reported upon by 

 Packard.^ In the infestation which reached its apex in 1878-79, this insect, 

 probably a native of this country, though well known in England, was responsi- 

 ble for the death of a large percentage of red spruce in the Casco Bay region 

 and in many other localities along the coastal area of Maine from Portland to 

 Rockland. The present outbreak comprises not only the coast regions but prac- 

 tically every wooded area of the State, the greatest amount of damage having 

 occurred in the inland portions, especially in Somerset, Piscataquis, Aroostook, 

 and Washington Counties, in regions remote from the coast and covered with 

 dense forests of spruce, balsam, fir, and mixed hardwoods. 



Attention is first attracted to it in the spring or early summer by the wilted 

 or blighted appearance of the new growth at the ends of the branches and twigs 

 of spruce and balsam. Investigations have shown the weakened trees to be
