Book excerpt: Excerpt from The Codling Moth and How to Control It by Spraying Only from 5 to 20 per cent. Of the larvae survive the winter. An examination of seven trees, which averaged 38 cocoons per tree in the fall, showed but 5 per cent. Alive in the spring, 87 per cent. Having been killed by birds, 4 per cent. By disease and 3 per cent. By cold. In another orchard cocoons were exam ined in May, 1907, with 19 per cent. Alive, 66 per cent. Having been killed by birds, 6 per cent. By disease and 9 per cent. By cold. It is quite evident that the birds, particularly the downy woodpeckers and the nuthatches are the most important enemies of the codling moth in New England and that they should be given every protection and be attracted to the orchard in every way possible. The Transformation. During May or early June, the cater pillar opens the end of the cocoon and spins a silken tube from it to the surface. Then retiring to the cocoon, with its head towards the opening, it sheds its winter clothes, transforming into a pupa. The pupa is a dormant stage in which the insect has almost no power of motion, and shows but little sign of life, but during which wonderful changes in its structure are going on, so that from the old tissues of the worm-like larva are formed the organs of the active, winged moth. In 1906 pupation com menced May 7, the last larva did not pupate until early in June, but the average date was May 25. In June, 1907, the average date of pupation was June 16 or three weeks later, while in 1908 the average date was June 1, the first pupa being on May 20 and the last June 9. The time of pupation is therefore seen to vary greatly with the season, but with average weather condi tions to occur about June 1.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Spraying for the Codling Moth The length Of time which elapses from the falling of the petals until the calyxes are fully closed varies for different varieties, and doubtless for the same variety in different seasons. It also varies for different clusters upon the same tree. In 1902, twenty clusters each of Whitney, Duchess, and Fameuse were marked with tags, and a record kept regarding the date of opening of each blossom, the falling Of the petals and the closing Of the calyxes. From this record, the number of days from the falling of the petals of the latest flower in each cluster to the complete closing of the first calyx in the cluster was determined. The shortest time was eight days and the longest seventeen days. The number of clusters for each number of days is indicated in the following table. Since not all the clusters set fruit, the total number is in each case less than twenty. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

As well as potatoes and sunflowers, exotic plants such as ginger and pak choi are being grown and people are running businesses from their allotment produce, tapping into the locally-sourced, seasonal food market. Gordon Thorburn shows how to make the best from your allotment or even a veg patch with tips on natural bug deterrents, companion planting (save your cabbages by planting marigolds amongst them) and a handy seasonal planner, as well as must-try recipes.
