654 EXPERIMENT STATION RECORD. [Vol 40 



The apple maggot in British Columbia, W. Dowxes (Cannd. Ent., 51 (1919), 

 No. 1, pp. 2-k). — The author records the collection of two specimens of the 

 apple maggot at Royal Oak, near Victoria, B. C, in August, 1917, previous to 

 which there had been only two authentic records of its capture on the Pacific 

 slope. A search for Its host resulted in finding it to infest the snowberry 

 (Symphoricarpos racemosusj, a very common shrub all over the drier parts of 

 the coast and interior of British Columbia. The adult fly has since been 

 taken by the author in the vicinity of Victoria and all over Saanich Peninsula 

 wherever the snowberry grows. A parasite reared from the pupre has been 

 identified as a new species of Opius. 



It is pointed out that the apple maggot was reported by Molander in 1911 

 (E. S. R., 26, p. 757) as destructive along the eastern border of the State of 

 Washington. 



Control of the apple maggot, L. Caesae and W. A. Ross (Cannd. Hort., 42 

 (1919), No. 2, pp. 27, 28). — The results of field tests conducted in various parts 

 of Ontario, extending over a period of five consecutive years and corroborated 

 by laboratory tests, led the authors to conclude that the apple maggot can be 

 successfully controlled in apple orchards by spraying. 



" The first application should be given just before or as the adults begin 

 to emerge, which in the southwestern part of the Province is about the last 

 week in June, and in the parts with a somewhat colder climate such ;is Gselph, 

 Stratford, and the district all along Lake Ontario about the first week erf July, 

 and in the still colder parts such as Ottawa and the St. Lawrence River 

 Valley about the second week in July. 



"The second application Bhould be made when the first has begun to dis- 

 appear, or usually in from two to three weeks, in wet seasons like the 

 summer of 1915, a third application about ten days after the second will be 

 necessary. Two years should almost completely destroy the Insect in any 

 orchard provided that Infested orchards are not situated close by. In such 

 case every effort should be made to have these treated also. Iu all orchards 

 every tree, whether bearing fruit or not, should be sprayed, because the adults 

 often frequent such trees until egg laying begins." 



Comparative tests show that the results were equally good where the arsenate 

 of lead was used alone as where combined with molasses. The authors recom- 

 mend the use of 2 to 3 lbs. of the paste form of arsenate of lead or 1 to 1.5 

 lbs. of the powder form to 40 gals, of water. 



Eumerus strigatus, the lunate onion fly in New Jersey, H. B. WBI88 and 

 A. S. Nicolay (Ent. News, SO (1919), No. 1, p. 27).— The authors record the 

 collection of this European species in a greenhouse at Rutherford, N. .1., on 

 February 0, 1918. 



A new species of longhorn beetle infesting cowpeas from Mexico, W. S. 

 Fisher (Proc. Ent. Soc. Wash., 19 (1917), No. 1-4. pp. 173. 174).— Under the 

 name Lepturges spermophagus the author describes a new- longicorn beetle 

 which is said to be the second longicorn recorded as infesting leguminous 

 plants. » 



A one-year life cycle for Saperda Candida reared in an apple. <J. O. BfiCKKB 

 {Ent. News, SO (1919). Xo. 1. p. -'^). — In this note, which supplements Bulletin 

 14G of the Arkansas Experiment Station previously noted (E. S. H., S8, p. 663), 

 the author records having reared the round-headed apple-tree borer through 

 all of its stages in the fruit of apple during a period of one year. 



The passion vine longicorn beetle (Monohammus fistulator). YV. YV. ETboo- 

 gatt (Apr. (!az. N. 8, Wales, 50 (J919), No. 1, pp. 37-39. figs. }).- A brief ac- 

 count of this beetle, which is a serious pest of the cultivated passion vine in 

 the Somersby district, near Oosford, New South Wales.
