  The 
  grasshopper 
  breeds 
  tlirougliout 
  the 
  year, 
  but 
  is 
  found 
  in 
  largest 
  

   numbers 
  in 
  the 
  rainy 
  season, 
  August-November. 
  

  

  The 
  grasshoppers 
  would 
  seem 
  to 
  copulate 
  more 
  than 
  once. 
  

  

  In 
  eleven 
  cases 
  of 
  grasshoppers 
  which 
  laid 
  eggs 
  in 
  cages 
  the 
  largest 
  

   number 
  of 
  eggs 
  laid 
  by 
  a 
  single 
  individual 
  was 
  177 
  (distributed 
  among 
  

   12 
  egg-masses) 
  ; 
  in 
  other 
  cases 
  there 
  were 
  163, 
  132, 
  and 
  131 
  (11 
  egg- 
  

   masses) 
  and 
  113 
  (8

  On 
  Eggs. 
  Owing 
  to 
  the 
  exposed 
  situation 
  of 
  the 
  egg- 
  masses 
  these 
  

   appear 
  to 
  be 
  subject 
  to 
  the 
  attack 
  of 
  numerous 
  parasites.

  Remedial 
  measures. 
  

  

  (1) 
  Ploughing 
  is 
  of 
  no 
  use 
  in 
  the 
  egg 
  stage. 
  

  

  (2) 
  Collection 
  of 
  eggmasses 
  is 
  contra-indicated 
  owing 
  to 
  the 
  presence 
  

   of

  (3) 
  Bagging 
  when 
  present 
  in 
  large 
  numbers. 
  

  

  Was 
  such 
  ovi'position 
  found 
  to 
  be 
  very 
  extensive 
  ? 
  

   When 
  the 
  paddy 
  was 
  three 
  to 
  four 
  months 
  old 
  we 
  were 
  able 
  to 
  collect 
  

   a 
  large 
  number 
  of 
  eggs 
  from 
  a 
  single 
  field.
