  During 
  the 
  campaign 
  of 
  February 
  and 
  March 
  1914, 
  against 
  Locusta 
  

   pardalina, 
  the 
  various 
  locust-birds 
  were 
  very 
  scarce. 
  Ciconia 
  alba, 
  

   the 
  European 
  stork, 
  usually 
  the 
  most 
  important 
  factor, 
  rendered 
  no 
  

   help 
  at 
  all, 
  and 
  none 
  of 
  the 
  small 
  locust- 
  birds 
  (Glareola 
  melanogaster) 
  

   were 
  seen. 
  The 
  wattled 
  starling 
  (Dilophus 
  carunculatiis), 
  although 
  

   doing 
  good 
  work 
  among 
  swarms, 
  does 
  not 
  follow 
  the 
  locusts 
  into 
  the 
  

   open 
  veld 
  or 
  dry 
  mountainous 
  country, 
  and 
  fruit 
  gardens 
  proved 
  a 
  

   greater 
  attraction 
  than 
  the 
  locusts, 
  havoc 
  being 
  played 
  with 
  ripe 
  figs 
  

   and 
  grapes. 
  It 
  is 
  during 
  the 
  nesting 
  season 
  that 
  this 
  starling 
  does 
  its 
  

   best 
  work 
  among 
  the 
  voetgangers. 
  Other 
  birds 
  mentioned 
  as 
  being 
  

   of 
  minor 
  importance 
  in 
  locust-control 
  are 
  the 
  spreuw 
  (Spreo 
  bicolor), 
  

   the 
  korhan 
  or 
  pouw, 
  the 
  blue 
  crane, 
  larks, 
  finches 
  and 
  a 
  glossy 
  starling.

  Locusts 
  w^ere 
  unexpectedly 
  numerous 
  this 
  spring, 
  and 
  appeared 
  on 
  

   ninety 
  farms 
  instead 
  of 
  on 
  three, 
  where 
  eggs 
  were 
  known 
  to 
  have 
  been 
  

   deposited. 
  In 
  spite 
  of 
  control 
  measures, 
  it 
  was 
  estimated 
  that 
  10 
  

   per 
  cent, 
  developed 
  to 
  the 
  winged 
  stage 
  ; 
  the 
  flying 
  swarms 
  spread 
  

   over 
  a 
  great 
  area 
  and 
  laid 
  eggs 
  almost 
  at 
  once. 
  The 
  brown 
  locust 
  

   (L. 
  pardalina) 
  was 
  heretofore 
  supposed 
  to 
  be 
  single-brooded, 
  but 
  the 
  

   laying 
  of 
  eggs 
  at 
  midsummer 
  led 
  the 
  Department 
  of 
  Agriculture 
  to 
  

   expect 
  a 
  second 
  generation 
  and 
  accordingly 
  special 
  field 
  work 
  was 
  

   undertaken 
  against 
  this 
  generation 
  by 
  Mr. 
  F. 
  Thomsen. 
  On 
  134 
  

   farms, 
  768 
  swarms, 
  estimated 
  at 
  389,000,000 
  insects 
  were 
  destroyed.

  During 
  the 
  spring 
  of 
  1912 
  the 
  work 
  of 
  a 
  small 
  lepidopterous 
  larva 
  

   was 
  noticed 
  in 
  the 
  buds 
  of 
  unsprayed 
  apple 
  trees. 
  In 
  a 
  neglected 
  

   orchard 
  near 
  the 
  laboratory 
  this 
  insect 
  was 
  the 
  most 
  important 
  

   factor 
  in 
  the 
  destruction 
  of 
  the 
  entire 
  crop 
  of 
  fruit. 
  The 
  species 
  

   proved 
  to 
  be 
  Recurvaria 
  crataegella, 
  Busck, 
  which 
  the 
  authors 
  

   suggest 
  is

  The 
  author 
  states 
  that, 
  with 
  a 
  few 
  exceptions, 
  birds 
  play 
  an 
  in- 
  

   significant 
  part 
  in 
  the 
  control 
  of 
  harmful 
  insects 
  in 
  Trinidad, 
  and 
  that 
  

   far 
  more 
  work 
  is 
  done 
  in 
  this 
  direction 
  by 
  parasites 
  and 
  predaceous 
  

   insects. 
  The 
  following 
  insects 
  are 
  abundant 
  in 
  localities 
  where 
  birds 
  

   are 
  plentiful 
  : 
  — 
  Cotton 
  stainer 
  (Dysdercus 
  howardi), 
  corn 
  bud-worm 
  

   (Laphygma 
  frugiperda), 
  tobacco 
  horn- 
  worm 
  {Protoparce 
  sexta), 
  tobacco 
  

   bud- 
  worm 
  (Chloridea 
  virescens), 
  cutworms 
  (Prodenia 
  spp.), 
  striped 
  

   cane 
  looper 
  (Remigia 
  repanda), 
  sugar-cane 
  bud-worm 
  {Cirphis 
  humi- 
  

   dicola), 
  froghoppers 
  (Tomaspis 
  spp.), 
  etc. 
  Some 
  birds 
  are 
  undoubtedly 
  

   harmful, 
  such 
  as 
  grass 
  birds, 
  doves, 
  the 
  little 
  black 
  corn-bird 
  (Molothrus
