154 EXPERIMENT STATION RECORD. 



twig borer; the bud moth; the jiiuiper scale {Diaspis cariieU), a European 

 pest which was found in such abundance on plants imported from abroad as to 

 seriously injure them; the box leaf miner (Motiarthropalpiis buxi) which seri- 

 ously attacked box hedges; the cottonwood leaf beetle (Lina scripta) which 

 fed on the leaves of poplars in a nursery at Agawam; the chestnut borer 

 (Leptura zehra), observed in connection with the chestnut bark disease; the 

 fall army worm, which was unusually abundant and destructive; and termites 

 (Tennes flavipes) w^hich attacked the stems of growing cabbages and corn 

 plants. 



General survey of the insect fauna of the soil within a limited area near 

 Manchester; a consideration of the relationships between soil insects and 

 the physical conditions of their habitat, A. E. Cameron (Jour. Econ. Biol., 

 8 {1913), No. 3, pp. 159-204, 2)7s. 2, figs. 3).— Part 1 (pp. 159-187) of this paper 

 consists of a general survey of the insect fauna of the soil at the grounds of 

 the experimental laboratory, Fallowfield; part 2 (pp. 187-199) deals with the 

 soil insects and the physical conditions of their habitat. 



Phytopathological report for the year 1912, P. Marchal (Bui. Agr. Alg4rie 

 ct Tunisie, 19 (1913, No. 9, pp. 193-199). — This report deals with the occurrence 

 of the more important insect pests of the year. 



Report of the entomologist, E. Ballard (Nyasaland Dept. Agr. Ann. Rpt. 

 1913, pp. 29-32). — This report deals largely with the occurrence of insect pests 

 during the year. 



List of insect pests, H. Morstatt (Pflanzer, 9 (1913), No. 6, pp. 288-296).— 

 This is a classified list of the more important insect enemies of plants and 

 plant products in German East Africa, with the nature of their injury. 



[Cranberry insects in 1912], H. J. Franklin (Massachusetts Sta. Rpt. 

 1912, pt. 1, pp. 225-234) • — This is a report of observations and study made of 

 cranberry insects on Cape Cod in 1912 in continuation of those previously noted 

 (E. S. R., 28, p. 352), and of which an account from another source has also 

 been previously noted (E. S. R., 28, p. 854). 



As regards the fruit worm (Mineola vaccinii) the author states that late 

 holding of winter flowage is the surest method of control thus far discovered 

 and that spraying as a remedy for it is still of doubtful practicability. There 

 are, however, a few bogs which can not be winter flowed that will pay a moder- 

 ate return if the fruit fly is kept within bounds. The experimental resanding 

 of such a bog on May 23 to a depth of 1 in., the uprights being raked up through 

 the sand when covered by it, was but partially successful, since numerous moths 

 were observed on netting which covered the experimental plat and some 40 per 

 cent of the berries which developed on this area were destroyed by fruit worms. 

 The author thinks that the best treatment for this insect on such bogs would 

 consist in the destruction of the remnant of the crop in the years when the 

 severe injury either from frost or winter-kill occurs and that this could prob- 

 ably be most readily done by spraying with a 20 per cent solution of iron sul- 

 phate. It is his opinion that as a rule more is lost through injury done to the 

 vine in harvesting a very light crop than is gained by saving and marketing the 

 berries. 



The flowed bog fireworm or blackhead cranberry worm (Rhopohota vaccini- 

 ana) is the source of but little or no damage on bogs that are not winter flowed. 

 The main cause of serious infestation by this pest is the killing and driving 

 ashore of its natural enemies by flowage, as was pointed out in the report of the 

 previous year. Through collections made by sweeping it was determined that 

 spiders are the most numerous of all forms capable of destroying the fire- 

 worms. Comparisons showed that the dry bog had far more spiders and also a
