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.

Excerpt from Directions for Spraying for the Codling-Moth There have been a great many suggestions as to different ways of controlling the codling-moth, and all that have come to. Our attention, that offered any prospect of even partial results, have been tested and found wanting, with the single exception of the arsenical Sprays. Possibly, at some future time, some other effective means may be discovered that will be as good, or better than the arsenicals, but up to the present time these substances stand far in the lead, and it is 5not' wise for the orchardist to experiment, except on the smallest scale, With anything else.

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 Spraying for the Codling Moth: Eastern and Western Methods Compared (a Preliminary Report) Undoubtedly the worst enemy. Of the apple crop in West Virginia is the codling moth - the insect that causes the wormy apple. This pest is taking altogether too much toll from the apple growers of our State and as our fruit industry is going forward by leaps and bounds more attention must be given to the control of this arch enemy of the orchardist.

Excerpt from Spraying the Apple Orchard: The Time to Spray for the Codling Moth In View of the comparatively small interest shown in fruit-growing in contrast to the great natural opportunities, it is well to inquire into the present conditions of apple cul ture in New Hampshire; for from a knowledge of present conditions we may be able to discern the possibilities of the future and the means of their realization.

Excerpt from The Laboratory-Field Method for Testing Codling Moth Insecticides For the main experiments Grimes and Jonathan trees 19 to 23 years old have been employed. Enough trees (usually 4 to 8) are employed to provide plenty of fruit for sampling. This may run up to apples on certain plots where both biological and chemical data are to be obtained. Sprays are applied with equipment and at pressures which represent average conditions for the area, and all parts of the trees are sprayed to or slightly beyond the point where run-off begins. Spraying is done by personnel of the Division of Fruit Insect Investigations, and the man in charge actively participates. Obviously, the risk of errors in mixing and of anything less than thorough Spraying (which might introduce extreme or uncontrolled variation, thereby endangering the accuracy of all biological and chemical data subsequently collected) is somewhat lessened when he does his share of the spraying. He is then better able to interpret unexpected developments, of which there are many. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
