Does the worm eat the seeds as well as the pulp of the apple? 5. Take a dozen rotting apples, how many of them are wormy? Do the parts of the apple injured by the worm begin to rot first? In how many ways does the codling moth injure the apple? Does it injure other fruits than apples? 6. How late in the fall do you find the codling larvce in the apple? Where do these larva go when they leave the apple? Work to be done in March or early April—^'^isit an orchard and look under the loose bark on old trees, or along protected sections of ferices or brush piles and bring in all the cocoons you can find. Do not injure the cocoons by tearing them from the places where they are woven, but bring them in on bits of the bark or other material to which they are attached. 1. How does the cocoon look outside and inside? What is in the cocoon? Why was the cocoon made? When was it made? 2. Place the cocoons in a box covered with cheese-cloth and place the box out of doors where the contents can be frequently observed and make the following notes; 3. When does the larva change to the pupa? Describe the pupa. How does the cocoon look after the moth issues from it? 4. Describe the moth, noting color of head, thorax, body, front and hind wings ? 5. If these moths were free to fly around the orchard, when and where would they lay their eggs? 6. When should the trees be sprayed to kill the young codling moth? With what should they be sprayed? Why should they not be sprayed during the blossoming period? Why not after the calyx closes?. Almost too late to spray. The apples on each side have the calyx lobes nearly drawn together. The pear in the middle still has the calyx cavity open. Photo by M. V. Slingerland..
