Book Description
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.

Excerpt from Experiments and Suggestions for the Control of the Codling Moth in the Grand Valley of Colorado Arsenate Of lime, both homemade and commercial, as used in plats VII and VIII, gave comparatively poor results. The unsprayed or check trees, plat X, were very Wormy, giving but 13. 51 per cent Of fruit free from larvae. The sprayed fruit was well protected against the calyx entrance worms except in plat VIII. With this exception, the percentage Of wormy apples infested. At the calyx in the sprayed plats varied from to The unsprayed plat produced per cent Of wormy fruit infested at the calyx.

Book Description
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.

Book Description
Allotments are enjoying a renewed popularity because people want to know exactly what theyre eating, save money, eat seasonally and save on carbon footprints. As well as men, more and more women are taking up the challenge to create their own sustainable food source with allotments, as well as experiencing the enjoyment of seeing things grow, not just fruit and vegetables, but also flowers. 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.
