Show the codling moth better work will always be done where founded on oil a knowledge of why it is done no excuse therefore Is needed for giving a summary of the insects lire life history the moth is a small shy creature rarely eier eer seen hying flying only in the dusk of the evening and then with a rapid zigzag motion hard to follow in color it resembles the ahe bark of the twigs with white stripes imitating tile the bloom bloam that is always found on oil growing shoots the eggs of 0 the first brood tiny white specks are laid on the upper surface of the leaves close to an apple rarely ever on oil the apple itself the majority of tile the second brood eggs are laid on oil the surface of the apples but not in the calyx end as formerly supposed the title little worms hatch and break through the top of the egg shell and immediately seek a hiding place which the greater number of them find in the calyx end of the apples and many of the remaining ones two apples touch the little worm bores down into tile the flesh of the apple those of the first brood go ing directly to abs tbs tap deeds eeds in most cases when ft I 1 grown they bore out on t the he side bt bf the apple even where they went in at the calyx end and crawl down the limb to the trunk of the tree where they spin a loose cocoon under tile the bark here they remain between two and three weeks when they appear as moths to lay eggs for the second brood broo d the second brood of worms come down in the same way but are arc more careful to find a good hiding place spinning a I 1 tough cocoon in which they remain all winter on oil account of the fact that the broods overlap all and that the second brood continues thru a long period many people have decided that there are more than two broods nut but everywhere that it lias has been carefully investigated throughout the larger part of the apple growing region two broods and two only have been found the great value of this knowledge lies in the fact that we earl can figure with absolute certainty dainty y that the few worms worm S of tile the first brood that survive the poison will not lot produce more than ten tell to fifteen bornis each during the rest of the season since as far as we kilo know a pair of codling met moths its 1 produce rd only from forty to fifty eggs and it will be rare that all of these flies e live to enter the apples our problem therefore is to kill the largest possible percentage of the first brood so that there will be very few left to propagate and to so place the patso poison that the greater number of their progeny will also bo be killed |
