in a strong mixture of Paris green and water, or with poisoned bran, were very sncce as" 

 fal. Cabbages, tomatoes, and other young plants were easily protected at the time o* 

 setting out with rings of paper or tin. 



The Oodling Moth (Carpocapsa pomonella, L ) was unusually prevalent and injur" 

 ious in unsprayed orchards. The standard spray for this insect is the poisoned Bordeaux 

 mixture, with which not only the fungous disease "Black Spot of the Apple" is treated, 

 but all foliage-eating insecls, as well as the Oodling Moth. The formula is copper 

 sulphate 4 lbs., fresh lime 4 tt>3., water 40 to 44 gallons, and Paris green 4 ozs. 



Tent Caterpillars. — The most remarkable occurrence of the season was of the two 



common species of Tent Caterpillars Clisiocampa 

 americana, Harr. (Fig 49) and C. disstria, Hbn. 

 r (Fig. 52) These two kinds of caterpillars which 

 were about equally abundant, stripped bare many 

 acres of Aspen Poplar, Basswood and Maple 

 Fig- 52 - groves along both banks of the Ottawa Eiver and 



along the Canadian Pacific and Canada Atlantic Railways in the counties of Carleton. 



The Ash-gray Pinion. — Maples were also extensively injured at Aylmer, Que., and 

 at Hull, Que., by the green caterpillars of Xylina Grotei, Riley, and X. antennata, 

 Walker. These caterpillars are known as Green Fruit "Worms, on account of their de- 

 structive habit of eating large holes in the sides of young apples and pears. In the 

 Ottawa district they did little harm in orchards, but stripped almost bare large forest 

 trees at the two places mentioned. This i i an uncommon attack which has not occurred 

 in anything like the severity of last season since 1885. The ashy-gray moths do not ap- 

 pear until late in the season. There are three species very similar in general appearance. 

 All of these may be taken at sugar- in the Ottawa District in September and October. 



The caterpillar of the Eye -spotted Bud-moth (Tmetocera ocellana, Schif), Fig. 53, 

 was rather common on apple trees in company with the Oblique-banded Leaf roller 

 (Gaccecia rosaceana, Harr), Fig. 54. The Oherry Web worm (Caccecia cerasivorana, Fitch), 

 Fig. 55, was extremely abundant on the wild bird cherries on the Laurentian mountains.

near Chelsea, Que., the unsightly webs attracting attention along the sides of the moun- 

 tain road. Although so abundant on the wild cherries, this insect did no harm to culti- 

 vated varieties. 



The Oyster Shell Bark louse. — (Mytilaspis pomorum, Bouche), Fig. 56, is 

 very common and destructive in this district, occurring not only on apple trees 

 but also on many other kinds of shrubs and trees in the garden and forest. It 

 was noted as injuriously abundant on red and black currants, lilac, spiraeas* 

 ash, dogwood (Comus), mountain ash and hawthorne. The Forbes scale was 

 found on the fragrant currant (Eibes aureum, Pursh), and the Putnam 

 scale on the elm. 



The White Cedar Lecanium (Lecanium Fletcheri, ckl.) and " Red 

 Spiders did some harm to cedar hedges. 



Canker worms were noticeably less abundant than usual, but the Bass- 

 wood Looper (Hybernia liliaria, Harr), Fig. 57, was very common, the deli- 

 cate male moths drawing the notice of the least observant by their clumsy 

 flight and the late season at which they appear. 



The Currant Saw ply (Nematus ribesii, Scop), was as usual abundant 

 and destructive where the bushes were not treated with the well-known 

 remedies, Paris green or White hellebore.
