The satin math has been recorded for the first time in woodland dis- 
tricts in New England. 
The hemlock spanworm has killed practically all of the hemlock in the 
resort region of Michigan and is now 'seriously damaging hardwood. 
A very heavy infestation by the two-lined, prominant ( Hemerocampa 
bilineata Pack.) attacking beech and oak is reported from Michigan. 
A considerable part of the Nhite fountain district of New Hampshire, 
a large part of Vermont and Maine, and parts of Massachusetts seem to be 
well infested by the birch leaf-mining sawfly.

The general application of control measures against the European corn 
borer has had very favorable results in Ontario. In spite of this, observa- 
tions indicate that in Kent and Essex counties sweet corn was more heavily 
infested than last year, although in the case of field corn the increase was 
only slight. The presence of this insect in Quebec has not yet caused seri- 
ous crop injury. In New Brunswick, in Sur.bury and -Queens Counties, the in- 
festation is extremely light. As a result of scouting, the borer has been 
found in Nova Scotia, in Yarmouth, Digby, and Annapolis counties. 
The grasshopper infestation in British Columbia, while not extremely 
severe as in 1926, again shows a tendency to increase. The exceedingly dry 
summer enabled the grasshoppers to lay their eggs successfully. Moderate 
outbreaks of grasshoppers alsc are reported from southern Quebec and south- 
eastern Prince Edward Island. 
Severe injury by white grubs to a vari sty of field and garden crops is 
anticipated over a fairly wide area in southern J»ue'.ec, in late fall, and 
during the soring of 1930. 
leather conditions have been favorable to the development and increase 
of the wheat-stem sawfly in southern Manitoba, but loss to wheat and rye 
does not excoed a few thousand dollars for the whole province. Damage to 
wheat by this species, in Saskatchewan, is believed to be moderately severe 
generally throughout the infested areas. Although tne infestation is not sc 
great as in former years the rate of damage appears to bo unusually high. 
Heavy infestations of the turnip aphis are reported from districts of 
southern New Brunswick and locally in southern Ontario. The pea aphis lias be 
reported in great numbers north of Lake Ontario in the counties of Prince 
Edward, No r thumb orl and, and Durham, and also in southern Quebec.
