We have among our fruit pests here in Maine one of the most 

 common, and one that does perhaps the most serious damage 

 to our fruit directly, the codHng moth. In the picture before 

 you, a female is seen in the act of laying her eggs on the apple, 

 and an enlarged one by the side showing somewhat the colors 

 of this moth, the adult insect. I will not take time to give the 

 life history of this insect because it is familiar to you all. We 

 must spray our orchards at the time when .the fruit is erect as 

 you see it, and the calyx cup open, to destroy this pest that does 

 so much injury to our fruit. 



The apple is here divided showing the work of the larva, the 

 young of this moth, as it has done the work and emerged from 

 the apple. 



Here is a highly magnified illustration of the complete, fully 

 developed larva before it goes into its cocoon to change to the 

 adult insect. 



Another pest that has done so much damage here. This is 

 the curculio, the apple showing the crescent-shaped impression 

 made by this beetle in the act of laying her eggs. 



The next slide represents the adult insect highly magnified, 

 showing quite a formidable insect. 



Next we have the so-called railroad worm or trypeta, the 

 adult being a two-winged fly about half the size of the ordinary 

 house fly ; the young of the same is shown at the bottom of 

 the slide. The only way to control this pest is to keep sheep 

 or hogs in the orchard, or to pick up the fallen fruit and feed 

 it to the stock. 



This is an insect that is familiar in the larval stage, perhaps 

 not so much so in the adult stage, the borer. This beetle lays 

 her eggs near the ground, the young of which remains two years 

 in the tree. A very serious pest in some sections of the State. 



We now come to the pest which has been so abundant this 

 year, the so-called fall web worm. It has never caused so 

 much destruction in any season before, as far as we know. 

 This is the web made by the caterpillars. 



The next slide will show you the adult caterpillars as they 

 appear on the twigs; they are quick, active fellows. 



The slide following shows the adult moth in the act of laying 

 her eggs on the under side of a leaf. The moth is very similar 

 to the so-called brown-tail moth, appearing about the same time,
