Last spring I saw an orchard in which every tree was badly infested. In some instances, the wintering cases literally covered portions of some of the smaller branches. It is true that the orchard referred to was a neglected one, so far as insects and fungi are concerned, but it is also true that both the Cigar-case Bearer „. ,^. „ , ^ ' '^ Fig-. 46. Bud-niotli and the Bud-moth are difficult to treat successfully. Both insects are well ^i^* \arva. protected by their coverings, and experience shows that thoroughly careful spraying at the right time is required to kill them. Fortunately for the orchardist, both begin active work about the same time, hence both can be treated at the same time. I feel that more demonstration spraying in the infested orchards is necessary before the fruit-growers will be convinced that these insects can be treated successfully. Seven or eight years ago it was shown that two or three applications of Paris green (4 ounces to the barrel) as soon as the cases became active in the spring, would hold the Case-bearers under control. Also, that kerosene emulsion, diluted with nine parts of water, applied at the same time was quite effective. Aphids were unusually abundant in many orchards. Insects Injurious to Shade Trees. The protection of shade trees from the attacks of boring insects is becoming quite a seri- ous problem in many of our towns and cities. It is becoming apparent that greater watchful- ness is required. The watchman, however, should have some acquaintance with the habits of the insects to be watched, so that remedies may be taken at the right time. One of the duties
