tioME Nature-Study Course. 



The blossoms and apples are always at the end of the twigs and spurs in th6 

 apple and do not grow along the branches, as in the cherry and the peach. Just 

 at the side and below the spur where the apple is borne a bud is developed, which 

 pushes on and continues the growth of the twig; and this in turn will be a spur 

 which will bear blossoms the following year. 



THE CODLING MOTH. 



Lesson XXVHL 



Purpose. — To make the pupils familiar with the habits of this insect 

 and the best way to protect fruit from its ravages. 



Material and method. — The 

 lessons should begin witji a 

 study of wormy apples, prefer- 

 ably in the fall when the 

 worms are still within their 

 burrows. After the pupils 

 become familiar with the ap- 

 pearance of the insect and its 

 methods of work, a prize of 

 some sort might be offered 

 for the one who will bring to 

 school the greatest number of 

 the hibernating larvae found 

 in their winter quarters. 

 Place these larvae in a box 

 with cheese-cloth tacked over 

 its open side; place this box out-of-doors in a protected position. Ex- 

 amine the cocoons to find the pupae about the last of April; after the 

 pupae appear look for the moths in about five days. 



It would be a very good idea for the pupils to prepare a Riker mount 

 showing specimens of the moths, the cocoons showing the cast pupa 

 skin, the caterpillar in a homeopathic vial of alcohol, and pictures 

 illustrating the work of the insect. The pictures should be drawn 

 by the pupils, showing the wormy apple, both the outside and the 

 front cut in half. The pupils can also sketch from pictures given the 

 young apple when just in the right condition to spray, with a note 

 explaining why. 



Observations by pupils. — 



(i). Find an apple with a codling moth larva in it. How large is 

 the worm? How does it act when disturbed?
