incidence of Helopeltis theivora (mosquito blight of tea) [R.A.E.,

Beeson (C. F. C). Some Problems in Forest Insect Control.— i^^i!>^. 



Proc. Srd Entom. Meeting, Pusa, February 1919, Calcutta, ii, 1920, 

 pp. 696-704. 



Accounts are given of some of the pests of outstanding importance 

 in Indian forestry, much of the information having been previously 

 noticed [R.A.E., A, iii, 729 ; vi, 521 ; vii, 135, 367 ; vih, 164, etc.]. 



A study of these pests indicates three classes of problems to be dealt 

 with, viz., the control of pests of intensive cultivation, which much 

 resembles agricultural entomological problems ; the reduction of 

 damage by insects to the standing crop, where the damage is greater 

 than that from other more easity controllable factors ; and the 

 prevention of pests likely to arise from new methods of forest manage- 

 ment, and particularly the creation of uniform forests and pure planta- 

 tions. A difficulty in dealing with the last two classes of problems is 

 the scale on which an inquiry has to be carried out, both in space and 

 time.
