THE  M0E3  IMPORTANT  H2C0HDS  102  MAY 

By  the  fourth  reek  in  May  egg  hatching  of  tho  migratory  grasshopper  and  the 
two-striped  gras sh  jpper  was  almost  completed  in  the  upper  Great  Plains  region. 
Complete  destruction  of  some  fields  of  crops  had  occurred  in  the  western  part  of 
the  Dakotas  and  N«  ' ro ska -and  in  eastern  Montana  and  Wyoming.  In  the  Southern 
Plains  region  hatching  of  the  migratory  range  grasshopper  -also  was  practically 
complete.  East  of  the  Great  Plains  migratory  grasshoppers  were  advanced  to  second- 
stage  nymphs  during  tho  third  week  in  tho  month  in  Michigan,  central  Wisconsin,  and 
in  parts  of  Minnesota  and  Iowa,  and  control  operations  are  well  under  way  at  sev- 
eral points.  In  southern  Missouri  hatching  was  well  advanced  during  the  second 
week  of  Mav,  In  the  Pacific  Northwest  the  migratory  grasshopper  and  tho  red-, 
legged  grasshopper  were  damaging  wheat  and  alfalfa  in  Idaho  during  the  first  week 
in  the  month. 

The  heaviest  infestation  by  the  Mormon  cricket  ever  recorded  in  South  Dakota 
was 'reported  during  the  second  week  in  the  month  in  Walworth  County,  This  insect 
was  also  reported  as  very  abundant  in  southern  Tooele  County,  Utah,  and  in  several 
counties  in  Nevada. 

Very  heavy  flights  ,of  June  beetles  are  reported  from  the  East  Central  States. 
Damage  to  pecans  by  these  insects  is  reported  from  the  lower  Mississippi  Valley. 

Damage  bv  wireworns  occurred  very  widely  throughout  the  country.  Heavy 
damage  to  tomatoes  and  watermelons  by  the  sugar  beet  wireworn  was  reported  from 
the  San  Joaquin  Valley  in  California. 

Very  heavy  infestation  by  grubs  of  Japanese  beetle  was  reported  from  south- 
eastern New  York  and  northeastern  Maryland. 

The' first  adults  of  white-fringed  beetle  were  collected  in  northern  Florida 
on  May  22.  Larvae  have  caused  serious  damage  to  crops  in  limited  areas  this 
season.  The  first  adult  was  taken  in  the  Now  Orleans  area  on  May  ll.  The  first 

papa  of  Naupactus  sp.  was  found  at  Saucier,  Miss.,  on  April  29  and  at  Gulfport 
Miss.,  on  May  1. 

In  general,  cutworms  were  subnormal  in  abundance  during  the  month;  however 
the  pale  western  cutworm  appeared  in  outbreak  numbers  in  western  Kansas,  where 
over  10,000  acres  of  wheat  had  been  destroyed  by  the  first  week  in  May* 

In  the  East  Central  States  there  was  a general  infestation  by. hessian  fly  in 
northern  Indiana  and  northwestern  Ohio. 


-Ill- 


-li  a 


Spring  migration  of  the  chinch  hug  to  snail  grain  started  during  the  first 
week  in  May  in  Indiana,  Illinois,  western  Missouri,  in  the  three  southern  tiers  of 
counties  in  Iowa,  and  in  southeastern  Nebraska  and  north-central  Kansas  during  the 
third  meek  in  May. 

The  greenbug ' is  generally  prevalent  throughout  the  Wheat  Belt  of  Kansas  and 
Oklahoma  but  little  injury  has  occurred  to  wheat  in  Kansas,  although  oats  and 
barley  have  been  damaged  in  places.  In  Oklahoma  oats  mere  a complete  failure  in 
Kay  County. 

A somewhat  heavy  flight  of  arnyworm  moths  was  reported  from  Indiana  during 
the  second  '■'■reek  in  May.  Some  damage  by  army  worm  is  also  reported  from  south- 
eastern Missouri  and  from  the  .Delta  counties  of  Mississippi* 

The  wheat  brown  nite  seriously  damaged  many  fields  of  wheat  in  western 
Kansas  and  southwestern  Oklahoma* 

Corn  ear  worm  damage  is  being  reported  from  the  South  Atlantic  .and  lower 
Mississippi  Valley  States.  Pupae  in  hibernation  cages  in  Illinois  failed  to 
pass  the  ’"inter,  but  in  the  St.  Louis  area  of  Missouri  a 23-percent  survival 
occurred.  Bather  severe  damage  to  corn  was  reported  from  southern  California* 

Pea  aphids  began  to  appear  in  the  Middle  Atlantic  States  early  in  the  month, 
largely  on  clover  and  alfalfa.  Severe  damage  to  alfalfa  was  reported  from  the 
northern  tier  of  counties  in  Indiana,  in  west— central  and  south-central  Illinois, 
in  southern  Michigan  end  Wisconsin,  and  in  eastern  Kansas,  Early  in  the  month 
damage  to  vetch  was  recorded  from  the  Willamette  Valley  of  Oregon  and  some  damage 
to  cannery  peas  was  reported  from  northwestern  Oregon, 

Tent  caterpillars  were  doing  considerable  damage  to  fruit  trees  in  Washington, 
Oregon,  and  California* 

First  adult  codling  moths  of  the  season  were  taken  on  May  3 at  Paducah,  Ky. , 
on  May  6 in  the  Vincennes  area  of  Indiana,  on  May  S at  Staunton,  Va. , end  in 
southern  Ohio,  in  northeastern  Kansas  and  northwestern  Missouri  on  May  10,  and 
on  May  19  in  central  Ohio. 

Very  heavy  populations  with  considerable  damage  by  the  fruit  tree  leaf  roller 
was  reported  from  western  Illinois  and  eastern  Missouri. 

Aphids  attackin'*  apple  wore  abnormally  abundant  early  in  the  month  in  Now 
England  ant  the  heaviest  infestation  in  the  last  10  years  occurred  during  the  latter 
part  of  the  month  in  the  Hudson  Hiver  Valley,  Heavy  infestations  also  reported  from 
western  New  York.  From  10  to  JO  percent  of  the  apple  crop  in  the  Cornelia  section 
of  Georgia  has  been  damaged  by  the  rosy  apple  aphid.  Increasing  damage  by  this 
insect  is  also  reported  from  the  Vincennes  area  of  Indiana.  Apple  grain  aphid  is 
very  prevalent  in  Michigan  and  Wisconsin,  In  the  latter  State  it  is  one  of  the  most 
severe*  outbreaks  ever  observed,

Inf  estation  by  the  plum  curculio  in  the  Port  Valley  section  of  Georgia  is 
heavier  than  usual.  A fairly  heavy  drop  of  peaches  is  also  recorded  from  the 
Cornelia  section  of  Georgia,  Increased  abundance  of  this  insect  was  reported 
fron  Kentucky,  Illinois,  Missouri,  and  Kansas, 

Large  pecan  trees  were  completely  defoliated  by  a tortricid,  Cacoecia  in- 
furaatana  Zell.,  in  southwestern  Louisiana,  This  appears  to  be  a new  pecan  pest. 

Potato  flea  beetles  were  seriously  damaging  potato  foliage  late  in  the  month 
in  New  York,  Virginia,  and  Indiana,  Heavy  infestations  ^ere  also  reported  from 
the  Pacific  Northwest, 

The  bean  leaf  beetle  was  generally  prevalent  along  the  south  Atlantic  sea- 
board and  in  the  East  Central  States. 

The  pea  weevil  reached  i.ts  peak  of  migration  into  fields  on  May  S in  Oregon 
and  between  May  13  and  15  in  Washington  and  Idaho, 

The  pepper  weevil  was  discovered  in  two*  additional  counties  in  Florida— 
Charlotte  and  Hillsboro. 

Flights  of  moths  of  the  beet  webworm  were  observed  in  the  latter  half  of  the 
month  in  Utah,  Idaho,  and  Montana. 

Large  populations  of  beet  leafhopper  were  reported  in  the  Promontory  Point 
breeding  area  of  Utah,  This  is  the  heaviest  infestation  in  the  last  4 years  for 
that  area. 

Heavy  populations  of  overwintered  cotton  boll  weevil  were  reported  from  South 
Carolina,  Georgia,  and  Florida,  with  somewhat  heavier  emergence  than  last  year  in 
Louis iana  and  Texas • 

A very  unusual  outbreak  of  cankerworns  covers  a wide  belt  from  Ohio ’across 
Illinois  and  Indiana  to  South  Dakota,  Nebraska,  and  Kansas.  Elms  and  unsprayed 
apples  in  many  places  are  completely  defoliated.

GENERAL  FEEDERS 
GRASSHOPRERS  (Acrididae) 

General*  W.  E.  Dove  (May  26):  In  the  Red  River  Valley  areas  of  Minnesota  and 
North  Dakota,  in  eastern  Montana  and  Wyoming,  and  in  western  North  Dakota, 
South  Dakota,  and  Nebraska,  hatch  of  migratory  grasshopper  Melanoplus  mexi- 
canus  Sauss.  and  two-striped  grasshopper  M.  bivittatus  Say ‘is  almost  complete^ 
while  hatching  of  the  big  yellow  grasshopper  M.  diff erentialis  Thos*  is  just  j 
beginning.  Rapid  hatch  and  acceleration  of  development  of  young  hoppers 
caused  by  warm,  dry  weather.  Rapid  movement  frcan  adjacent  idle  and  range 
lands  into  cropped  areas  temporarily  reduced  by  rains  occurred  during  the 
week.  Although  average  percentage  of  damage  to  crops  in  the  northern  Great 
Plains  area  remains  small,  some  fields  have  been  completely  destroyed  in 
parts  of  Wyoming,  eastern  Montana,  and  the  western  part  of  North  Dakota, 

South  Dakota,  and  Nebraska,  Heaviest  damage  where  grasshoppers  hatched  in 
fields  in  which  the  grain  had  been  stubbled  in.  Hatching  of  migratory  range 
grasshopper  in  the  Texas  Panhandle,  Oklahoma,  northeastern  New  Mexico,  and 
eastern  Colorado  practically  complete  in  some  areas  and  less  advanced  in 
other  areas  of  higher  altitudes,  A very  small  hatch  occurred  in  the  Missis- 
sippi Valley  during  the  last  week, 

Michigan.  R.  Hutson  (May  24):  M.  mexicanus  seen  throughout  the  Lower  Peninsula. 
Second-stage  nymphs  observed  in  several  places  as  far  north  as  Roscommon, 
Camnula  pellucida  Scudd.  observed  hatching  at  Roscommon  and  in  the  south- 
eastern counties,  Ageneotettix  deorum  Scudd,  is  in  the  same  stage  of  devel-

hatching  began  about  April  15. 

Minnesota,  A.  G.  Ruggles  and  assistants  (May  20 ):  Main  hatch  of  M,  mexicanus 
amounts  to  8 percent  in  some  spots  and  100  percent  in  the  Red  River  Valley, 
First  hatch  recorded  on  April  27*  M.  bivittatus  second  to  M.  mexicanus. 

Very  few  C,  pellucida  hatched  to  date.  Hatching  reported  as  started  in 
Chisago,  Otter  Tail,  Bennington,  and  St.  Louis  Counties. 

Iowa.  C.  J.  Drake  (May  26):  M.  bivittatus  and  M,  mexicanus  hatching  in  large

progress  for  2 weeks,  particularly  near  the  larger  cities.  Semi-drought  con- 
ditions favorable  for  young  grasshoppers  during  the  hatching  poriod, 

Missouri,  L,  Haseman  (May  24);  Hatch  in  the  north-central  part  of  Missouri  de- 
layed by  the  weather,  and  until  the  middle  of  May  very  little  hatching  had 
occurred  in  the  northern  tier  of  counties.  Heavy  hatch  in  places  reported 
from  southern  Missouri  2 weeks  earlier, 

G,  D,  Jones  (May  10) : North-central  Missouri  is  the  area  most  heavily 
infested  with  eggs,  according  to  the  survey  of  last  fall,  which  indicated 
that  more  than  normal  egg  populations  exist  in  every  district  where  grass- 
hoppers were  abundant  last  year.  Eggs  held  back  in  development  owing  to  cool

in  the  northern  part  of  the  Panhandle,  M.  confusus  Scudd,  generally  dis- 
tributed over  the  pasture  land  of  the  western  half  of  the  State,  many  having 
reached  the  adult  stage,  and  damaging  some  pastures.  Hatching  of  M,  differ- 
ent ialis  and  M.  bivittatus  delayed,  and  nymphs  not  appearing  in  damaging 
numbers  yet. 

Montana.  H.  B.  Mills  (May  20):  Practically  a 100-percent  hatch  of  eggs  of  M.

involving  Richland,  McCone,  Garfield,  Petroleum,  Rosebud,  Treasure,  Custer, 
Prairie,  and  Dawson  Counties.  At  the  same  time  approximately  20  percent  of 
the  eggs  had  hatched  north  of  the  river,  the  hatch  being  about  a week  later 
than  in  the  southern  -area. 

Idaho,  W,  E,  Shull  (May  5) • Populations  of  M,  nexicanus  and  M,  f emur-rubrum  Deg,

Utah,  G.  F.  Knowlton  and  F.  C.  Harnston  (May  18):  Reported  as  causing  consider- 
able damage  to  fall  wheat  in  Carbon  County,  especially  in  the  area  near  Pries,! 

WIREWORMS  (Slateridae) 

New  York.  N.  Y.  State  Coll.  Agr.  News  Letter  (May  22) j Apparently  more  numerous 
in  Orleans  County,  western  New  York,  than  usual.  Eastern  field  wireworms 
(Limonius  ectypus  Say)  proving  a considerable  pest  in  several  greenhouses  in 
Monroe  County,  western  New  York,  Evidence  indicates  that  they  are  breeding 
in  these  locations. 

North  Carolina.  J.  U.  Gilmore  and  W.  A.  Shands  (April):  Quantitative  sampling 

of  Monocrepidlus  spp.  done  on  November  3,  1933,  in  a field  of  soybean  stubble 
near  Reeky  Mount,  an  averags  of  1.2  wireworms  per  square  foot  being  found  by 
examining  a 6- inch  depth  of  soil  in  10.  square-foot  samples  taken  at  random. 
Thirty-two  similar  samples  "on  March  27,  after  field  had  remained  undisturbed 
during  fall  .and  winter,  showed  an  average  of  1.9  wireworms  per  square  foot. 
Fields  thoroughly  plowed  to  a depth  of  about  6 inches  soon  after  March  27,  and 
on  April  12,  from  J>2  similar  samples,  there  was  found  an  average  of  .1,1  .wire- 
worms  per  square  foot.  Soil  loose  and  rather  dry  on  last  sampl.ing  date  and 
it  seems  probable  that  some  wireworms  were  below  the  6-inch  depth  of  sampling. 
Sampling  on  first  date  confined  to  on  area  of  0.4  acre,  while  for  the  second 
and  third  dates  original  area  extended  to  include  1-|  acres. 

Georgia,  T.  L.  Bissell  (May  19):  Corn  at  Experiment,  in  a dates-of-planting  test 
following  Austrian  peas,  now  attacked  by  wireworms,  possibly  Monpcrepidius 
sp. , of  which  29  were  found  in  208  stalks. 

Missouri,  L.  Haseman  (May  24);  A few  scattered  reports  of  serious  damage  to 
corn  received  from  the  north-central  part  of  the  State, 

Nebraska,  D.  B.  Whelan  (April  27):  Wireworms  ( Ludius  sp. , possibly  L,  aoripennis 
Kby. ) found  feeding  in  a grasshopper  egg  mass  from  York  on  April'  21,  Others 
of  the  same  species  found  in  similar  locations  on  the  same  date,  three  being 
the  most  in  any  one  capsule.  Other  wireworms,  Limonius  sp. , taken  from  a 
wheatf ield  near  Kimball,  (Det.  by  A.  G.  Boving. ) 

Kansas,  H.  R,  Bryson  (April  27):  Small  wireworms,  Aeolus  dorsalis  Say,  numerous  in

California.  M.  W.  Stone  (May  20):  Tomato  plantings  in  Orange  County  thinned  out 
- considerably  during  May  from  attack  by  L.  californicus.  In  a 10-acre  field 


-119- 


near  Santa  Ana  over  5U  percent  of  the  plants  were  killed,  and  in  a 6-acre 
planting  near  Stanton  over  3S  percent  of  the  stand  was  replanted.  Lima  "beans 
planted  early  in  May  also  damaged  extensively.  In  parts  of  a 60-acre  plant- 
ing near  Santa  Ana  every  seed  examined  was  infested  with  from  1 to  9 larvae, 
and  an  average  of  5 larvae  obtained  per  foot  of  row.  Damage  in  the  6CUacre 
planting  of  melons  near  Downey,  Los  Angeles  County,  continues.  Between  April

B,  E . Campbell  (May  l):  Many  watermelon  fields  in  southern  Eresno  County, 
central  California,  being  damaged  by  L,  canus  Lee.  In  a typical  20-acre  field 
the  infestation  was  scattered,  except  in  one  corner  where  over  2 acres  were  al- 
most completely  denuded  of  plants.  Counts  on  5 plants  showed  from  l6  to  4g 
wireworms  attacking  a single  plant,  averaging  26  per  plant.  Eield  had  been 
replanted  4 times,  4 acres  being  abandoned  and  planted  to  kafircorn.

New  York.  N.  Y.  State  Coll.  Agr.  News  Letter  (May  15) ; Situation  serious  in 

•Westchester  County.  To  determine  a cross  section  of  the  county  a square  foot 
of  turf  was  taken  up  from  90  areas  in  April  and  grubs  counted.  Number  per 
square  foot  was  from  29  to  83,  averaging  6l. 

D.  M.  Daniel  (-May  29):  In  fS  diggings  in  Westchester  County  from  April  11

CEREAL  AND  FORAGE-CROP  INSECTS 
WHEAT  AND  OTHER  SMALL  GRAINS 
HESSIAN  FLY  (Phytophaga  destructor  Say) 

General,  C.  Benton  (April  20):  Pupation  started  near  La  Fayette,  Ind, , about 
April  1.  Dissections  made  on  April  19  showed  32  live  pupae-  present  in  100 
puparia.  No  emergence  of  the  flies  has.  been  observed.  A spring  survey  of 


-123- 


fall-sown  wheat  was  made  from  March  7 to  April  5,  covering  4S3  fields _ in  SO 
counties  of  Indiana;  34  fields  in  4 southeastern  Illinois  counties;  22  fields 
in  4 northwestern  Ohio  counties;  end  l4  fields  in  2 south-central  counties  of 
.Michigan.  In  the  area  covered  the  2 sections  showing  the  most  general  infesta- 
tion by  the  fall  "brood  were  northwest-central  and  northeastern  Indiana  and 
adjacent  counties  in  northwestern  Ohio.  In  these  areas  many  fields  were 
heavily  infested,  with  thinned  stands  of. wheat  in  poor  condition  of  growth. 

Ohio.  T,  H.  Parks  (May  22);  Ho  serious  damage  to  wheat  is  anticipated  in  any  part 
of  the  State. 

Indiana.  C.  Benton  ( May  22);  Pupae  were  found  throughout  April.  First  fly  emer- 
gence and  egg  laying  occurred  on  April  26.  The  crest  of  fly  emergence  and  egg 
laying,  first  week  of  May,  gradually  decreased  until  May  22.  First  small 
larvae  found  on  May  3*  Mostly  half-grown  larvae,  with  a few  full-grown,  were 
found  "by  May  20  in  wheat.  About  10  percent  of  overwintered  puparia  still  con- 
; tained  viable  larvae  not  pupated  on  May  20. 

Kansas.  E.  T.  Jones  (May  26);  Of  17  wheat fields  examined  on  May  24  in  Geary, 
Dickinson,  and  Marion  Counties  infested  plants  were  found  in  15.  Based  on 
samples  of  5^  stems  each,  average  infestation  per  field  was  9*7  percent,  rang- 
ing from  2 to  30  percent,  with  an  average  of  3*7  puparia  per  infested  stem. 

He  injury  apparent . 

CHIHCH  BUG  (Blissus  leucopterus  Say) 

South  Carolina.  W.  C,  Hetties  (May  22);  Present  but  less  abundant  than  formerly 

in  Chester  County.  Of  10  small-grain  fields  surveyed,  only  2 had  corn  planted 
adjacent,  which  apparently  will  help  protect  the  corn. 

Indiana,  C.  Benton  (May  23);  Si>ring  migration  to  small  grains  started  about  May 
1 and  was  practically  completed  by  the  middle  of  May.  First  mating  observed 
in  the  field  on  May  9«  By  May  20  more  than  50  percent  found  mating.  Present 
numbers  found  in  small-grain  fields  near  La  Fayette  show  a few  spots  in  thin 
winter  wheat  and  rye,  with  enough  old  bugs  to  produce  a light- to-noderate 
infestation  with  continuation  of  present  favorable  dry-field,  conditions.  Ho 
eggs  or  nymphs  were  observed, 

Illinois.  W.  P.  Flint  (May  26);  Scattered  reports  of  infestation  are  coming  in. 
Infested  fields  widely  separated  in  most  areas,  the  worst  infestations  occur- 
ring in  heavily  pastured  rye. 

Iowa.  C,  J,  Drake  (May  26);  Very  abundant  in  the  three  southern  tiers  of  counties 
of  the  State,  and  here  and  there,  infestation  extends  into  the  fourth  tier. 
Weather  conditions  favorable  this  spring  for  the  bugs  to  move  from  winter 
quarters  to  the  small-grain  fields. 

Missouri,  L.  Haseman  (May  24);  Scattered  reports,  particularly  from  west-central, 

southwestern,  and  northwestern  Missouri,  indicate  some  rather  heavy  infestations, 
but  the  infestation  is  not  general  throughout  the  State. 

G.  D.  Jones  (May  10);  Reported  in  considerable  numbers  in  the  southern, 
western,  and  northern  parts  of  the  State.  Most  genera.1  and  heavy  infestation 


-124- 


found  in  tho  northwestern  area.  Cool  spring  has  kept  then  in  hibernation 
, longer  than  usual,  and  movement  to  grainfields  evidently  took  place  only 
recently.  Fall  survey  indicated  localized  infestation  similar  to  last  year. 

Nebraska.  M.  K.  Swenk  (May  18):  Chinch  hugs  were  flying  early  in  May,  especially 
during  the  period  from  May' '6  to  l4,  in  southeastern  Nebraska  northwest  to 
Lancaster  and  Saline  Counties.  Injury  to  barley,  rye,  and  wheat  reported 
since  May  8 in  this  area. 

Kansas.  H.  R.  Bryson  (May  27):  Reported  as  abundant  on  May  10,  in  sene  wheat- 
fields  in  Nemaha  County.  From  8 to  12  bugs  per  square  foot  were  counted  in 
1 field.  Numerous  in  Smith,  Cloud,  Republic,  Saline,  and  Dickinson  Counties, 
north- central  Kansas. 

GREEN  BUG  (Tpxoptera  graninum  Rond. ) 

Missouri.  L.  Has e man  (April  27):  No  complaints  received, 

Kansas.  E.  T.  Jones  (May  26):  Numerous  infestations  of  aphids  were  noted  on  May 
24,  on  wheat  and  oats  in  Geary,  Dickinson,  and  Marion  Counties-.  Some  injury 
’observed.  Predators  also  numerous. 

H.  R.  Bryson  (May  23):  Present  all  over  the  Wheat  3elt  in  Kansas,  In  most 
localities  no  injury  to  the  wheat,  but  injury  to  barley  is  common.  Serious 
damage  to  oats  and  winter  barley  in  southern  Kansas  and  to  spring  barley  in 
northwestern  Kansas. 

Oklahoma,  F.  A.  Fenton  (May  22):  The  outstanding  insect  infestation  during  the 
last  month  seems  to  be  the  green  bug*  Infestation  apparently  most  severe  in 
Kay  County,  centering  r round  Ponca  City,  but  extends  from  this  county  in  all 
directions.  Wheat  crop  now  beyond  the  point  of  serious  injury  and,  as  a 
whole,  injured  very  little.  Oat  crop  in  that  section  almost  a total  loss, 
and  a great  deal  of  corn  destroyed, 

Texas.  R.  K.  Fletcher  (May  8):  Taken  from  wheat  in  Dallas  County.  (Det,  by  P. 

W,  Mason.) 

PLANT  BUGS  (Miridae)

range  land  in  the  Reese  Greek  area,  northern  part  of  Gallatin  County. 

Washington,  R.  D.  Shenefelt  (May  l6):  At  Pullman  Thyrillus  pacificus  Uhl,  was 

attacking  a strip  of  wheat  about  20  feet  wide  by  300  feet  in  length.  Apparent- 
ly increasing. 


ARMYWOEM  (Cirphis  unipuncta  Haw.) 

Virginia.  H,  G.  Walker  and  L.  D.  Anderson  (May  27):  Very  scarce  this  spring  at 

Norfolk,  only  one  grower  having  reported  injury,  and  the  infestation  was  very 
light.

A few  winged  aphids  collected  during  the  last  several  days  in  northern 
counties • 


-129- 


Oregon.  D.  C.  Mote  (May  19):  Aphids  have  continued  to  increase  in  peafields  in 
the  Willamette  Valley  since  early  April,  and  field  peas  are  injured  in. 
places.  In  most  vetch  fields  examined  the  predators  have  held  the  aphids  in 
check.  More  aphids  were  reported  as  infesting  the  cannery  peafields  oi 
Umatilla  County,  than  any  year  since  193^* 

M.  M.  Reeher  (May  22);  Alates  began  moving  into  late  fall-sown  fields 
on  April  17*  On  April  20  a few  early  fall-sown  fields  of  common  vetch  and 
Austrian  winter  field  peas  were  beginning  to  show  some  damage  to  individual 
tips.  By  May  15  several  early  fall-seeded  Austrian  winter  field  peas  began 
to  show  damage  in  places.  Some  late  fall-sown  peas,  close  to  early  fall- 
sown  fields  also  show  some  injured  spots.  Common  vetch  showed  some  tips 
killed  late  in  April  and  early  in  May.  By  May  9 most  of  these  fields  had 
been  nearly  freed  of  aphids  by  coccinellid  larvae  and  beetles.  Injury  not 
serious  on  either  vetches  or  field  peas  but  probably  increasing  in  Austrian 
peas,  owing  to  few  natural  enemies,  fungous  disease  has  remained  at  a very 
low  point,  owing  to  dry  weather.  Aphids  did  not  increase  as  rapidly  on 
Austrian  peas,  as  expected  and  it  is  believed  that  some  of  this  retardation 
of  reproduction  may  be  attributed  to  the  slow  growth  of  the  plants  during 
dry  weather.

Virginia.  A.  M.  Woods ide.  (May  22):  Moths  first  caught  in  hait  traps  at  Staunton 
on  May  8 and  began  to  emerge  in  the  insect ary  on  the  sane  day.  Oviposit  ion 
proceeding  rapidly. 

Georgia.  J.  E.  Webb,  Jr.  (May  23):  Peak  o'f  emergence  of  overwintered  noths 

occurred  at  Cornelia  about  the  middle  of  May.  Light  egg  deposition  owing  to 
cool,  rainy  weather,  indicating  a light  first  brood  of  larvae. 

Ohio,  T,  H.  Parks  (May):  First  moths  taken  in  bait  traps  at  South  Point,  southern 
Ohio,  on  May  8 and  at  Delaware,  Central  Ohio,  on  May  19,  about  the  normal 
time  for  adults  to  emerge. 

Indiana.  L,  F.  Steiner  (May  23):  In  the  Vincennes  area  spring-brood  moths  began 
emerging  on  May  6,  and  activity  well  bunched,  with  peak  flight  extending  from 
May  13  to  22.  Tree  examinations  showed  that  79  percent  of  the  brood  had 
pupated  and  4l  percent  emerged  by  May  17,  with  39-percent  pupation  and  6S-per- 
cent  emergence  on  May  22,  Carry-over  in  most  orchards  about  normal. 

Kentucky.  W,  A.  Price  (May  23):  Adults  began  emerging  at  Paducah  on  May  3,  and 
emergence  was  heavy  by  the  middle  of  May.  At  that  time  most  of  the  over- 
wintered larvae  had  pupated  in  the  vicinities  of  Paducah  and  Princeton. 

First  adults  found  at  Lexington  on  May  19* 

Michigan.  R.  Hutson  (May  24):  About  50-percent  pupated  at  Saint  Joseph, 

Wisconsin.  C.  L.  Fluke  (May  19):  Some  larvae  have  not  pupated.  Trees  in  Craw- 
ford County  now  ready  for  treatment  but  moths  are  apparently  very  late, 

Missouri  and  Kansas.  H.  Baker  (May):  Orchard  checks  indicate  that  11  percent  of 
the  overwintered  larvae  in  northeastern  Kansas  and  northwestern  Missouri  had 
pupated  by  April  21,  and  50  percent  by  May  3*  First  moths  caught  in  bait 
traps  on  May  10,  and  bait-trap  catches  heavy  since  May  15.  Ho  eggs  found  in 
an  examination  made  on  May  12,  and  only  a few  bn  May  17. 

Missouri.  L.  Hasenan  (May  24):  Owing  to  the  peculiar  spring,  emergence  of  over- 
wintered generation  pretty  well  bunched  aver  the  State.  From  the  north  to 
the  south  records  indicate  a difference  of  only  a few  days  in  the  peak  of 
spring  moth  emergence,  ranging  from  around  May  17  to  May  23  and  24. 

Kansas.  H.  R.  Bryson  ( May  27):  Abundant  in  Doniphan  County  on  May  25,  as  well

Observations  in  Plymouth  County  showed  first  larvae  appearing  about  May  1. 
Along  roadsides  webs  were  beginning  to  be  quite  conspicuous  but,  although 
numerous,  apparently  not  quite  so  abundant  as  last  year  or  the  year  before. 

New  York.  E.  P.  Eelt  (May  23):  Somewhat  common  in  New  York  State  west  to 
Syracuse. 

R,  E.  Horsey  (May-  23 )i  Although  a considerable  number  of  nests  are  to  be 
seen,  especially  along  neglected  fence  rows  of  wild  cherry  and  apple,  there 
are  not  as  many  nests  at  Rochester  as  in  the  last  2 years.  Observod  on 
Japanese  quince,  crab  apple,  and  cherry. 

New  Jersey.  E.  A.  Soraci  (May  5)?  Very  abundant  in  spots  in'  New  Jersey,  south 
of  a line  from  Phillipsburg  to  Elizabeth,  Practically  no  injury  in  the

of  Danville  defoliated  by  May  5,  Much  less  common  in  the  Shenandoah  Valley, 

South  Carolina.  E,  Sherman  and  W.  C,  Nettles  (May  22):  Less  numerous  than  usual 
on  orchard  trees. 

Michigan.  R.  Hutson  (May  24):  Very  numerous  about  Saginaw,  Harrisville,  Cadillac, 
Muskegon,  Shelby,  Hesperia,  and  Clarel 

Wisconsin.  H.  J.  MacAloney  (May  l6):  Common  on  pin  cherry  (Prunus  penns ylvani cum) 
along  fence  rows  in  eastern  Wisconsin.  Near  Milwaukee  tents  and  caterpillars 
larger  than  at  the  Menominee  Indian  Reservation,  4o  miles  north.  This  is  due 
to  the  more  advanced  stage  of  foliation. 

Correction:  The  apple  tree  tent  caterpillar  reported  by  S.  E.  Bailey  in  Insect 

Pest  Survey  Bulletin,  Mayj.f1939»  page  89,  is  M,  calif ornica  Pack.,  instead  of

Illinois.  Larvae  about  half  grown. 

Missouri.  L.  Haseman  (May  24):  Again  observed  in  unusually  heavy  numbers,  and 
older  larvae  now  approaching  maturity.  Unusually  large  amount  of  fruit  on 
the  tree  being  attacked  by  larvae  and  treatments  have  not  checked  them.  Al- 
though only  eastern  Missouri  Wcas  heavily . involved  last  year,  it  is  reported

May  4 and  7.  More  advanced  aphids  in  York  County  now  in  the  third  instar. 

Ho  adults  observed.  Humber  of  aphids  on  developing  buds  now  reduced,  owing 
to  prolonged  cool  weather  and  natural  enemies.  Ho  nymphs  of*  rosy  aphid 
( Anur aphis  roseus  Bakor)  observed,

and  green  aphids.  (May  22):  Heavy  population  of  .grain  and ‘green  aphids  re- 
ported In  western  Hew  York  the  first  of  the  rmnth.  By  the  middle  of  May  rosy 
aphids  were  observed  to  be  multiplying  rapidly  in  the  Hudson  Valley,  By  May 
S,  in  Hiagarn  County  rosy  aphids  had  been  observed  as  far  more  numerous  on 
the  buds  close  to  the  trunks  than  on  the  outsides  of  the  trees.  Dozens  of 
buds  inside  had  nothing  but  rosy  aphids"  and  outside  none.  As  high 'as  l6

Only  a few  apple  grain  aphids  remain  in  the  orchards  in  the  Vincennes  area, 
(May  23):  Rosy  apple  aphid,  almost  impossible  to  find  early  in  May,  has 
increased  during  the  last  2 weeks  to  such  an  extent  that  damage  will  be  more 
severe  in  some  orchards  than  in  193&*

general  over  the  entire  State. 

Missouri.  L.  Haseman  (May  24);  Very  few  complaints  received  and  in  central 

Missouri  only  an  occasional  tree  shows  any  evidence  of  rosy  aphids.  Reported 
as  showing  up  to  some  extent  in  northeastern  Missouri  in  practically  all 
orchards.  Predators  feeding  heavily  on  them,  so  no  great  damage  expected.

COTTON  INSECTS 
BOLL  WEEVIL  (Anthonomus  grand is  Boh.) 

South  Carolina.  E.  F.  Bondy  and  C.  F.  Rainwater  (May  27):  Very  active, 

as  the  week  has  "been  warm  in  Florence  County.  A total  of  175  weevils 
removed  from  cages  during  the  week,  as  compared  to  21  in  193^ . 
Examinations  in  the  field  show  generally  more  weevils  in  the  field 
for  the  week  than  in  1938,  as  follows:  1 to  43  plants  in  1939:  and 
1 to  128  in  1932.  Emergence  from  cages  in  May  totaled  635  this 
year,  as  compared  to  2l6  in  1938.  Trap— crop  and  screen— trap  catches 
less  than  in  1938. 

Georgia.  P.  M.  Gilmer  and  P.  A.  Glick  (May  20):  Practically  all  fields 
in  Dooly,  Tift,  Cook,  Lowndes,  Berrien,  and  Echols  Counties  show 
infesta.tion;  those  planted  in  the  vicinity  of  old  fields  quite 
heavily  infested  in  spots.  Fields  remote  from  hibernating  quarters 
or  from  old  cotton  have  light  infestations,  averaging  from  1 to 
3 weevils  per  1,000  plants.  Average  is  about  1 to  2 weevils  per 
500  plants  in  large  fields  and  from  4 to  6 per  500  in  small  fields. 

Florida.  C.  S.  Rude  and  L.  C.  Fife  (May  27):  Found  in  several  fields 
in  Lake  County.  Heaviest  population  noted  to  date  was  17  weevils 
per  100  plants  in  a field  that  was  in  cotton  last  season.  None 
found  in  Lake  County  in  1938  until  about  August  1.  Many  farmers 
using  control  measures.  Light  populations  found  in  each  of  the 
fields  where  experimental  plots  are  located.  In  treated  and  un- 
treated fields  examined  in  Alachua  County  infestation  ranged 
from  0.5  to  78  percent;  in  Union  County  from  0 to  10  percent;  in 
Marion  County  from  2.6  to  27.8  percent;  in  Gilchrist  County  from 
0.2  to  12.2  percent;  and  none  found  in  Putnam  County.  For  the 
same  period  last  year  infestation  in  these  counties  ranged  from  0 
to  14  percent,  but  cotton  was  not  so  far  advanced  as  this  season. 

Stub  cotton  in  some  old  fields  is  heavily  infested. 

Mississippi.  E.  W.  Dunnam,  et  al.  (May  27):  In  Washington  County  9 
weevils  found  on  150  cotton  plants  next  to  woods.  Plants  in  the 
6-leaf  stage.  This  area  yields  weevils  earlier,  as  cottoa  la 
usually  seeded  earlier  than  in  other  .fields  'examined.. 

Louisiana.  R.  C.  Gaines  and  assistants  (May  27):  Weevils  removed  from 
hibernation  cages  in  Madison  Parish  through  the  week  ended  May  26 
totaled  as  follows:  311,  or  0.89  percent,  in  1939;  and  310,  or 
0.89  percent,  in  1938.  Total  taken  on  field  flight  screens  for 
the  week  was  7,  as  compared  with  5 in  1938  and  3 in  1937.  Popula- 
ln  fields  in  Madison  Parish  has  averaged  almost  the  same  as  in 
1-/3°*  x94  being  found  on  4l,000  plants  inspected,  or  1 per  211  plants. 

Texas.  F.  L.  Thomas  (May  24):  Weevils  continue  to  emerge  from  hiberna- 
tion quarters  and  now  exceed  average  survival;  already  occurring 
m noticeable  numbers  near  hibernating  quarters.

RED-HEADED  ELEA.  BEETLE  (Systena  hudsonias  Eorst.) 

Louisiana.  P.  K.  Harrison  (May  12):  Observed  as  attacking  cotton  and 

doing  moderate- to-severe  damage  in  the  Baton  Rouge  area.  Smartweed, 
a wild  host,  was  growing  on  turn  rows  and  also  "being  attacked, 

COTTON  LEAP  WORM  (Alabama  argillacea  Hbn.) 

Texas.  E.  L.  Thomas  (May  12):  Eirst  leaf  worm  of  the  season  found  in 
Cameron  County  on  May  4,  a three-f ourths-grown  larva  being 
collected  at  San  Benito, 

R.  L.  McG-arr,  et  al.  (May  20):  Eirst  record  for  this  season 
in  Calhoun  County  made  on  May  17 , when  two  leaf  worms  were  taken 
from  cotton  on  a farm  7 miles  west  of  Port  Lavaca.  One  larva  about 
full  grown. 

PINK  BOLLWORM  (Pectinophora  gossypiella  Saund.) 

Texas.  H.  S.  Cavitt  (May  27):  Total  moth  emergence  somewhat  lower  than 

last  week.  Only  11  moths  from  winter-buried  and  irrigated  treatments. 
A big  drop  in  emergence  from  the  cocoon  series,  37  as  compared  with 
62  last  week.  All  but  3 moths  emerged  from  cocoons  not  disturbed 
following  installation  of  the  larvae.  Only  3 moths  emerged  from 
thurberia  bolls  this  week,  as  compared  to  15  last  week.  Apparently 
emergence  from  these  bolls  is  practically  over. 

APHIDS  (Aphiidae) 

South  Carolina.  C.  E«  Rainwater  (May  20):  Observations  this  spring  in 
Elorence  County  have  brought  out  more  forcibly  than  before  the 
fact  that  Trif idaphis  phaseoli  Pass,  is  the  most  serious  root  aphid 
on  cotton.  Usually  a heavy  mortality  to  seedling  cotton  wherever 
it  occurs.  One  severely  infested  field  in  this  vicinity  has  not 
more  than  25  percent  left  of  the  plants  that  came  up. 

Arizona.  E.  R.  Tinkham  (May  12):  Aphis  gossypii  G-lov.  quite  abundant

COTTON  ELEA  HOPPER  (Psallus  seriatus  Reut . ) 

Texas.  E.  L.  Thomas  (May  24):  With  the  exception  of  a few  fields  in 
southern  Texas,  flea  hoppers  have  not  done  much  damage  to  early 
planted  cotton.  There  has  been  a substantial  increase  in  the 
numbers  of  young  flea  hoppers  which  practically  doubled  during 
the  last  week  in  Calhoun  County.  Hatching  of  overwintered  eggs 
apparently  nearly  over  in  southern  Texas,  but  in  central  Texas 
considerable  numbers  have  hatched  since  the  rains.  In  north- 

ern and  northwestern  Texas  the  hatch  is  running  into  fairly  large 
numbers.

A WHITEFLY  (Trialeurod.es  sp.) 

Arizona.  T.  P.  Cassidy  (April):  Beginning  to  appear  generally  on  seedling 
cotton  in  the  Tucson  area,  hut  only  one  field  found  where  infesta- 
tation  is  heavy  enough  to  he  noticed'.  No  damage  reported. 

THRIPS  (Thysanoptera) 

South  Carolina.  - J.  G.  Watts  (May  10):  Sericothrips  variabilis  Beach 
and  Frankliniella  fusca  Kinds  have  Been  doing  a.  little  damage  to 
seedling  cotton  at  Blackville,  more  than  in  1938  hut  less  than 
normal . 

C.  P.  Rainwater  (May  20):  Thrips  appeared  suddenly  in  Florence 
County.  Last  week  practically  none  on  cotton  and  this  week  a heavy 
infestation.  Apparently  they  came  to.  cotton.- at  the  time  the  first 
small  grain  was  being  harvested. 

F.  F.  Bondy  and  C.  F.  Rainwater  (May  27) J Some  damage  to 
young  cotton  in  Florence  County,  hut  not  severe  and  loss  than  in  1938. 

Mississippi.  E.  W.  Dunnam,  et  al.  (May  27):  Of  44  plants  examined  on 
May  25  at  the  experiment  station  in  Washington  County,  1 was  in- 
fested with  1 thrips;  on  May  26  of  75  plants,  25  .were  infested  with 
31  thrips;  and  of  75  other  plants,  19  were  infested,  with  21  thrips. 

Texas.  F.  L.  Thomas  (May  6):  Some  d.amago  continuing  to  cotton  in  most 
sections  of  the  State.  More  abundant  than  usual  in  the  southern 
and  central  parts  of  Texas  since  spring  began.  Early  increase, 
stimulated  by  the  mild  winter  and  the  cool,  dry  weather  of  the  last 
few  weeks,  has  retarded  the  growth  of  cotton  so  that  feeding  by 
thrips  has  caused  leaves  to  curl  and  on  some  plants  killed  terminal

Connecticut.  E.  P.  Eelt  (May  23):  Pali  cankerworms  (Alsophila  pometaria 
Harr.)  relatively  scarce*  although  a few  have  "been  reported  in 
southern  Connecticut. 

Ohio.  T,  H.  Parks  (May  22):  Spring  cankerworms  (Paleacrita  vernata  Peck) 
and  the  fall  species  "both  very  abundant  and  seriously  defoliating 
elm  trees  along  streams  in  the  central  counties  of  Ohio.  Spring 
cankerworms  began  hatching  the  first  week  of  May  and  the  fall 
cankerworms  a few  days  later. 

Illinois.  W.  P.  Elint  (May  26):  Outbreak  resulted  in  heavy  .defoliation 
of  woodland  elms  and  unsprayed  apple  trees  throughout  the  north- 
western and  west-central  parts  of  Illinois.  Thousands  of  elms  and 
honey  locusts  in  this  area  almost  completely  defoliated.  Nearly  all 
farm  orchards  in  same  condition.  Parasites  relatively  scarce. 

Larvae  through  feeding  over  nearly  all  the  area  except  the  extreme 
northern  part. 

South  Dakota.  H.  C.  Severin  (May  12):  Much  trouble  at  present  in

throughout  most  of  the  southern  half  of  the  State,  and  some  infes- 
tation here  and  there  in  the  northern  counties.  Many  elm  and  apple 
trees  in  the  vicinity  of  Des  Moines  entirely  defoliated.  Although 
spring  cankerworm  by' far  the  dominant  species,  some  fall  canker- 
worms  found.  More  damage  done  to  elm  and  unsprayed  apple  trees 
in  southern  Iowa  than  for  several  years. 

Missouri.  L.  Haseman  (May  24):  Spring  cankerworm  more  destructive  than 
ever  known  before  in  the  Kansas  City  area,  particularly  in  the 
country  surrounding  Columbia,  and,  judging  by  reports,  in  other 
parts  of  the  State.  Dozens  of  large  mature  elms  comoletely  stripped 
of  foliage.  Reported  as  very  serious  along  the  Mississippi  River, 
in  northeastern  Missouri,  with  the  heaviest  infestation  in  the  St.  ’ 
Louis  area.

J.  R.  Korton  (May  6):  Spring  cankerworms  "began  to  appear 
in  considerable  numbers  at  Wichita  almost  as  soon  as  the  trees 
began  to  come  into  leaf.  A large  percentage  of  street  and  yard 
elm  and  maple  trees  all  over  the  city  now  almost  completely  de- 
foliated. Webbing  very  conspicuous.  Similar  outbreak  last  year 
stopped  short  of  extensive  defoliation  such  as  this.

many  localities,  infestation  in  general  has  decreased  considerably. 
Counts  made  in  severo.1  widely  separated  localities  indicate  the 
average  egg  deposit  in  1938  as  50  percent  less  than  in  1937* 

Eggs  still  rather  abundant  in  some  localities.  Infestation  heavy
