ONION FLY (Anthomyia ceparum) —The remedies offered for this well-known __ 
pest are careful preparation of ground which has not borne onions the previous 
year, growing them in trenches so that the bulb may be kept covered, the re- 
Let 
moval of diseased bulbs, and the treatment of infested plants with what is 
practically a kerosene emulsion or simply with soap suds. 
SLuGs.—These troublesome mollusks are not insects but are treated in the 
manual because so frequently sent in by people who suppose they are. Gas-lime, 
lime, and salt if applied frequently at short intervals are sure remedies. 
THE DIAMOND-BACK Mota (Plutella cruciferarwm).—This insect frequently 
so injurious to cabbages in this country is spoken of as an occasional pest of 
turnips. A dry dressing of gas-lime, one bushel ; lime from the kiln, one bushel; | 
sulphur, 6 pounds ; and soot, 10 lbs., was found useful. 
In Part II. “ Forest Trees and the Insects that injure them,” there are no 
insects which actually injure our forest trees in Canada although the general 
principles of prevention and remedy give valuable suggestions. 
In Part 11. “ Fruit Crops and Insects that injure them,” we find many too — 
well known enemies of the orchardist. 
THE WooLLy APHIS (Schizonewra lanigera).—Of the many remedies given 
it seems to us that the treatment of the stem inhabiting form with soap-washes 
or kerosene emulsion will be the most effective, and the latter is probably the 
best remedy for the root inhabiting form which is so difficult to reach. . 
APPLE ApuHIs (Aphis mali).—Syringing with soft-soap and other washes is. 
recommended. 
CopLine MorH (Carpocapsa pomonella).—Scraping, banding, and washing 
the trees, form the chief remedies. Spraying with Paris green. This is the first 
mention of this now universally used American remedy. Up to last year Paris 
green aS an insecticide was unknown in England. Now however at Miss 
Ormerod’s suggestion it has been tried and has proved so successful that there is 
no doubt that it will rise rapidly in public favour. Probably some from careless- 
ness or recklessness, in not following the instructions closely, will put on the 
washes too strong and injure the foliage ; but the benefits which will follow its. 
adoption will be so enormous that Miss Ormerod will speedily be recognised as a 
public benefactor by thousands of the ignorant educated people in Great Britain 
who “did not know that grubs and creeping things were of any interest to them.” 
MussEL ScaLeE (Mytilaspis pomorwm).—This is our familiar oyster-shell 
bark louse. The usual soap washes in spring and the mechanical removal of the 
scales are recommended. 
GOOSEBERRY SAW-FLY (Nematus ribesii, Curtis).—Great stress is laid on the 
value of removing the surface soil from beneath bushes which have been infested 
by the larve. Mention is made of some mixtures containing soot or sulphur. 
We are surprised to find that “ white hellebore ” is not mentioned. 
SHoT Borer “ PEAR Buicut” (Xyleborus dispar).—A most complete article 
is given on this insect which has been very injurious in our Maritime Provinces. 
for some years ; preventive remedies in the shape of washes to prevent the females 
from laying eggs are given. 
MoTrLeD UMBER Motu (frybernia defoliaria).—This moth is interesting to 
us from the fact that it has been taken on three occasions in Vancouver Island 
by Rev. George W. Taylor—whether indigenous or introduced is uncertain. 
This is one of several moths which have been very injurious for many years. 
in England but which have been successfully treated during the past season with 
Paris green. A long article detailing the experiments of the Evesham Fruit 
Conferenee with Paris green, under Miss Ormerod’s guidance, gives an account of 
the successful introduction of Paris green into England as an insecticide. J. F.
