. Annual report. Entomological Society of Ontario; Insect pests; Insects -- Ontario Periodicals. H'ig. 33. (Quarter of an Apple"shewing the work of the Ccdling Worm ; the insect in all Apple-Weevil (greatly magnified). did not lay her eggs till the fruit was about the size of a pea and continued laying till it was at large as a hickory nut ; during this period spraying should be done. Mr. Fisher said that the calyx (at the tip of the young fruit) closes about a week after the blossom falls, and therefore it is necessary to spray early. Prof. Lochhead found the Haseltine trap-lanterns perfectly worthless as regards the destruction of the Codling moth. They caught as many beneficial as injurious insects, but n© Codling moths. " The Expansive Tree-protector" is all right in principle, as it is a bandage, but he found in nearly every instance that it was doing harm to the tree. The poisonous sub- stance with which the felting is soaked was not effective ; the Codling larvse were lively and active in it, also spiders and other insects which took advantage of the shelter. He had also found larv;e crawling over the sticky substance which was supposed to be a complete barrier against them. The worst feature about it is that it is said to expand automatically with the growth of the tree ; he found that it failed to do so, but gradually cut right into the wood through the bark and in time girdled the tree ; this could only be prevented by frecjuentlj opening and moving it. Sacking or burlap was ever so much better, as well as cheaper and simpler. He was surprised to find how remarkably active the agents have been in selling these " protectors" ; they were to be seen in orchards all over the country. Mr. Evans said that in his trap-lantern (described in the last Annual Eeport)he had iaught a great variety of insects, but no Codling moths. They are evidently not attracted by light.
