476 Notes on Insect, Fungus, and other Pests, [sept., 



number. The destruction of the galls in which the pest is 

 pupating would help to reduce the attack next year. At 

 Leighton, Welshpool, a plantation of Sitka Spruce, some 

 1 8 acres in extent, and only formed last year, was attacked 

 by the clay weevil, Otiorhynchus picipes. No information 

 was sent as to the amount of damage done, but the Board 

 were informed that the insect was easily trapped under sods. 

 In the neighbourhood of Cemmaes, and elsewhere in N. 

 Wales, damage to larch from the Larch Miner moth 

 (Coleophora laricella) is reported to be easily seen, though 

 it often appears trifling compared with the damage done by 

 Nematus Erichsoni. The damage in the Lake District is also 

 very marked. These small caterpillars, which attack other 

 trees as well as larch, are usually hatched about July, and feed 

 till October, when they hibernate in their cases till April or 

 the beginning of May ; they then resume feeding for a few 

 weeks, pupating in May, and becoming moths in June. 



The most interesting of the fungus pests forwarded for in- 

 vestigation was found on some leaves of Cox's Orange pippin, 

 grown at Aspall, in Suffolk. The disease had been noticed 

 in previous years, but had not been reported, and seems to 

 have spread. The leaves were blotched by the fungus 

 Cladosporium herbarum Link., an exceedingly common sap- 

 rophyte, which, under certain conditions, becomes parasitic, 

 and injures living plants, especially if these are weakened by 

 weather or other unsuitable conditions. The foliage of many 

 apples is liable to attack, and Cox's Orange pippin often 

 suffers severely. Treatment with dilute Bordeaux mixture 

 in the spring would probably check the development of the 

 spores. 



Wheat sent from St. Fagan's was badly affected by yellow 

 rust (Puccinia glumarum), dealt with in this Journal in July, 

 1908, p. 241. 



Tomatoes from Tovil, Maidstone, were severely attacked by 

 a fungus disease, apparently Phytophthora infestans, though 

 in the absence of fruiting mycelium this could not be stated 

 definitely. Tomatoes in Kirkmuirhill showed marks of 

 Cladosporium fulvum, but the attack was very slight.
