. Annual report. Entomological Society of Ontario; Insect pests; Insects -- Ontario Periodicals. 116 THE REPORT OF THE. No. 19 mends as a remedy, the dusting of tlie plants in tlie evening with white helle- bore, or with Paris green mixed with 50 times its weight of common flour, or some other dry diluent. The Oblique-banded Leaf-eoller, Archips rosaceana, Harr. (Fig. 54). This widely distributed leaf-roller, the caterpillar of one of the tortricine moths, is very common in Ontario and has a great range of food plants. At Ottawa the larvae have been particularly abundant on apple, and in flower gardens we have found the species on roses, climbing honeysuckles, geraniums, spiraeas, and many other plants. The caterpillar besides rol- ling up the leaves very often has the habit of tying together the upper leaves and buds of flowering plants and then destroying the flowers. When full grown it is about three-quarters of an inch in length, green, with a darker green dorsal vessel; the head black in front, brownish at the top, as is also the top of the first body segment; the feet all black. This leaf-roller, although common and widespread, has never occurred in gardens in Ontario to re- quire much attention. Handpicking as a rule will serve as a remedy, but if the caterpillars should appear in numbers spraying with some poiso would soon destroy Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Entomological Society of Ontario; Ontario.
