. Annual report. Entomological Society of Ontario; Insect pests; Insects -- Ontario Periodicals. e i Fig. 54. Oblique-banded Leaf-roller moth. Ants (Fig. 55). Enquiries are frequently made for information con- cerning ants which infest garden plants of many kinds. It is generally believed that these insects do harm to plants, but this is not the case. In most instances, if close observation is made, it will be found that plant lice are present and are the real cause of the injury. The relations of ants to plant lice are very interesting. It is well kno^vn that ants are protectors of plant lice; they are very fond of the sweet honey dew which is emitted by them, and certain kinds even actually colonize them on plants near or inside their nests. Some ants indirectly, therefore, are very injurious, al- though they do not themselves feed upon plant tissue. When they are seen to be running about on plants, a search should be made for their nest which will, in all probability, be located in the earth close by. When this is found a tablespoonful of bisulphide of carbon should be poured into it and the opening immediately closed up by stepping on it. The fumes from this liquid will penetrate quickly into all parts of the nest, and not only kill the adults but the larvae as well. This material is very inflam- mable and care must be taken not to bring a light near it. Another remedy is to pour scalding water into the nests. Red Spider. Although chiefly a greenhouse pest, these minute mites are often found doing considerable damage to the foliage of plants in flower gardens, particularly during hot, dry seasons. The presence of these small creatures on the plants is easilv detected by the leaves losing their colour, having a white, bleached appearance, and becoming stunted. These mites live by sucking out the juices from the leaves and in this way.
