region excepting the Coastal plain. The northern limit reached by this pest 
IS southern Ontario, Canada, Monroe Comty in the southeast corner of Michigan 
and Lrie, V/yommg, and Livingston Counties in the r/esternmost corner of l-Tev,- 
York State. It extends thence southv;ard across the center of Pennsylvania 
eastward as far as Tioga, Center, and Huntingdon Counties, and still forther 
eastward along the southern border of the State to Lancaster County, thence 
across the east-central part of r.Iaryland from Harford County to Frederick 
County, continuing southv/ard across Virginia through Fairfax, Alexandria, Al- 
bemarle, and Pittsylvania Counties into l\iorth Carolina, in -.-.hich State it ex- 
tends decidedly more to the eastward, being recorded from as far east as llor- 
tnam, i-itt , and Duplin Counties. In Georgia, the pest remains in the northern 
half of the State -.Tith the single exception of the territory around Thoraasville 
on the southwestern border. To the v/estv;ard the insect has made but little 
advance. In Alabama the territory has extended but very slightly to the south, 
and the Mississippi territory has remained practically the same as last year. 
In Kentucky and Tennessee it has moved about one or tv/o tiers of coiuities 
.westward, while in Indiana similar slight w-estward movements are recorded, the 
insect still being some distance fro i the Illinois State line.

The European corn borer has extended its range considerably in northern 
Ontario and southern Quebec. In Ontario, larval collections have been taken 
in the counties of Algoma, Sudb^jry, I'ipissintr, Parry Sound, lluskoka, St. 
Joseph-'s isXand, and L'anitoulin Island; and in •H.uebec, in the counties of 
Fontiac, Hull, Papineau, Argenteuil, Two I.'ountains, L ' Assomption , Vavidreuil , 
Jacques Cartier, Laval, Beauliarn oi s , A'apierville , Li ssi s^uoi , and Champlain, 
all south of latitude '47. The most northerly point in Canada at which the cor. 
borer has been found is north of latitude ^17 at Haileybury, in the county 01

A recent survey has revealed a marked reduction in the extent of infest- 
tion of the v/heat stem saT7fly in south-western Manitoba. The average infesta- 
tion v.'as found to be about S per cent, resulting in an actual loss of less than 
1 per cent.^ In Sasl^itchewan, damage by this insect is undoubtedly much less 
than in 192o, although considerable losses have been reported from the Swift 
Current district in the south'^'estern portion of the province. 
Collections of the s"'eet clover 1 eaf -.T.iner , Parectopa albicogtella 
Braun, indicate a general distribution of this insect throughov.t south^-estern 
Manitoba. 
Observations ■.-.lade in the Peace River Block, 3r iti sh Colfnbia, reveal 
that the grasshoppers which have been a serious pest in this area for a number 
of years ^-^re completely wiped out tMs season by heavy spring rains which 
fell shortly after the grasshoppers had hatched. Grasshoppers catised serious 
danTage to clov-er and he foliage oi' youii^ a,?ple trees in the Iberville and
