Report on injurious insects in Finland for the year 1901, E. Reuter 

 {Lundbr. Styr. Mcddel. [Helsingfors'], 1902, No. 39, pp. 74)- — The larger part of this 

 report is occupied with an account of the insects which are injurious to grasses and 

 cereals, esi)ecially the insects which produce silver-top condition in these plants. 

 An account is given of the extent to which silver-top condition prevailed in various 

 parts of Finland during the year and of the insects which were chiefly instrumental 

 in causing this damage. A large number of insects produce this effect, chief among 

 which the author mentions species of Lasioptera, Pseudococcus, Isosoma, Pedicidoides 

 graminum, Tarsonemus cnbnicolus, Aptinothrips rufa, and Erioplnjes cormttus. The 

 amount of damage caused l)y these insects upon various species of meadow grasses is 

 shown in tables, and an alphabetical list of species of gra.sses is given, together with 

 the species of insects injurious to each grass. 



A brief catalogue is also presented of the insect" which cause silver top in grasses, 

 arranged in a systematic order. For the jnirpose of preventing the injuries thus 

 caused to grasses the author recommends immeiliate harvesting of the grass as soon 

 as the damage begins to appear, and subsequent treatment by removal from the field
