  hoppers

  have

  years. 
  They 
  move 
  

   in

  Genesee 
  county 
  (J. 
  F. 
  Rnse, 
  South 
  Byron) 
  — 
  Appletree 
  tent-cat- 
  

   erpillars 
  [Clisiocampa 
  americana] 
  appeared 
  in 
  unusual 
  numbers 
  

   last 
  week. 
  The 
  season 
  is 
  backward, 
  and 
  no 
  leaves 
  show 
  on 
  the 
  apple- 
  

   trees 
  and 
  the 
  buds 
  are 
  but 
  little 
  swollen. 
  The 
  caterpillars 
  are 
  feeding 
  on 
  

   the 
  blossom 
  buds 
  of 
  those 
  varieties 
  which 
  are 
  considerably 
  advanced. 
  

   The 
  lines 
  of 
  silk 
  lead 
  from 
  the 
  nests 
  to 
  the 
  fruit 
  spurs. 
  The 
  nests 
  are 
  

   very 
  numerous 
  on 
  the 
  wild 
  cherry, 
  and 
  on 
  these 
  no 
  leaves 
  have 
  appeared. 
  

   May 
  I. 
  I 
  am 
  unable 
  either 
  by 
  observation 
  or 
  by 
  inquiry 
  of 
  prominent 
  

   fruit 
  growers 
  to 
  learn 
  that 
  the 
  cold 
  did 
  any 
  injury 
  to 
  the 
  young 
  cater- 
  

   pillars. 
  Ice 
  ^ 
  of 
  an 
  inch 
  thick 
  formed 
  here, 
  and 
  there 
  were 
  hard 
  frosts 
  

   for 
  several 
  nights. 
  May 
  11. 
  Tent-caterpillars 
  are 
  very 
  bad 
  in 
  many 
  

   orchards. 
  Spraying 
  is 
  neglected 
  by 
  many 
  till 
  the 
  caterpillars 
  

   have 
  attained 
  considerable 
  size, 
  and 
  then 
  they 
  have 
  poor 
  success 
  

   in 
  killing 
  them 
  with 
  paris 
  green. 
  When 
  the 
  poison 
  has 
  been 
  used 
  

   at 
  the 
  rate 
  of 
  i 
  pound 
  to 
  100 
  gallons 
  or 
  stronger, 
  the 
  results 
  have 
  

   been 
  better. 
  Many 
  of 
  the 
  caterpillars 
  are 
  now 
  full-grown 
  and 
  

   have 
  begun 
  to 
  travel, 
  preparatory 
  to 
  spinning 
  their 
  cocoons. 
  Can- 
  

   kerworms 
  have 
  been 
  working 
  so 
  badly 
  in 
  some 
  orchards 
  that 
  spraying 
  

   while 
  the 
  trees 
  were 
  in 
  full 
  bloom 
  has 
  been 
  done. 
  Eye-spotted 
  bud 
  

   moths 
  [Tmetocera 
  ocellana] 
  have 
  greatly 
  increased, 
  and 
  many 
  

   are 
  found 
  on 
  pears 
  and 
  quinces. 
  Potato 
  beetles 
  [Doryphora 
  lo- 
  

   lineata] 
  were 
  found 
  in 
  numbers 
  today, 
  though 
  they 
  had 
  been 
  scarce 
  

   previously. 
  May 
  26. 
  The 
  early 
  potato 
  and 
  tomato 
  leaves 
  look 
  like 
  

   sieves, 
  as 
  the 
  result 
  of 
  the 
  work 
  of 
  the 
  cucumber 
  flea 
  beetle 
  [Crepi- 
  

   dodera 
  cucumeris]

  is 
  present 
  in 
  usual 
  numbers. 
  Tent-caterpillars 
  are 
  far 
  more 
  

   numerous 
  than 
  ever 
  before 
  and 
  are 
  now 
  crawling 
  everywhere. 
  The 
  

   forest 
  tent-caterpillar 
  [Clisiocampa

  not 
  as 
  bad 
  as 
  last 
  

   year. 
  The 
  pear 
  psylla 
  [PsyUa 
  pyricola] 
  has 
  been 
  very 
  trouble- 
  

   some 
  and 
  difficult 
  to 
  control. 
  June 
  12. 
  I 
  was 
  called 
  to 
  see 
  an 
  orchard 
  

   which 
  is 
  in 
  a 
  very 
  serious 
  condition 
  from 
  the 
  attacks 
  of 
  an 
  insect 
  [palmer 
  

   worm. 
  Ypsolophus 
  pometellus]. 
  June 
  14. 
  The 
  crop 
  in 
  this 
  

   orchard 
  of 
  300 
  trees 
  is 
  a 
  complete 
  failure, 
  though 
  there 
  was 
  a 
  full 
  bloom. 
  

   It 
  was 
  sprayed 
  with 
  paris 
  green 
  only, 
  the 
  first 
  time 
  when 
  the 
  fruit 
  was 
  as 
  

   big 
  as 
  peas 
  and 
  then 
  last 
  week. 
  Tent-caterpillars 
  were 
  also 
  rather
