CoAz (J.). Ueber das Auftreten des grauen Larchenwicklers {Stc^anop- 

 tycha pinicolana, Zell.) als Schadling in den Larchenwaldungen 

 im Kanton Graubiinden, insbesondere des Oberengadins, und im

 monia diniana as a Pest of Larch Forests in the Canton of Orisons 

 especially in the Upper Engadine, and in the Canton of Tessin 

 in 1911, 1912 and 1913, and Combative Measures against it.] —

 (Abstract in Centralbl. Bakt. Paras. Infekt., Jena, lite Abt., 

 liii, no. 4-12, 31st March 1921, p. 226.) 



A period of 23 years elapsed between serious outbreaks of Enarmonia 

 diniana {Sfeganoptycha pinicolana) in the Upper Engadine in 1886- 

 1888 and 191 1-1913, instead of the previous periods of 8, 13 and 6 vears. 

 In the 1911-1913 outbreak the injury to larch reached its maximum 

 in June 1912, and the moths were most numerous on the wing in 

 September of that year. In 1913 Hymenopterous parasites ended 

 the outbreak. The best method for combating this pest consists in 

 establishing mixed plantations of spruce and Pinus cenibra throughout 

 the Upper Engadine up to 5,900 ft., and even 7,600 ft. if the imported 

 spruces, Picca pnngens, P. engclmanni and P. sitchensis are grown. 

 Nesting facilities should be provided for insectivorous birds.
