174 AGRICULTURAL EXPERIMENT STATION. 



The Second brood is generally on the wing the latter part of Juty. 

 The moths of the first brood not appearing all at the same time and 

 the great length of time required for the female to lay her eggs 

 would give larva of all ages and cause the broods to lap over each- 

 other. The second brood generall}' deposit their eggs in the late 

 apples and if the larva are matured before gathering time they leave 

 the fruit and spin cocoons as mentioned above, but when taken to 

 the cellar they spin their cocoons between the staves and hoops of 

 the barrels or about the bins. 



The fall brood remains in the larval form within the cocoon until 

 spring, when it emerges, completing the life history. 



It would seem from the investigations of Mr. Charles G-. Atkins,, 

 recorded in Agriculture of Maine, 1883, p. 356, that in this State 

 we sometimes have but one brood of the Codling Moth. My 

 observations the past season indicate two broods, lapping over eacb 

 other so as to indicate that eggs are deposited in July, August, Sep- 

 tember and the first part of October. Larva one- half grown were 

 found in November. 



REMEDIES 



The modern and perhaps best way to hold in check this pest is to 

 spray the trees, abcjut the time the apples are forming, with Paris 

 Green suspended in water, by means of a force pump There should 

 be at least two applications covering the time of emergence of the 

 moths and the period of laving eggs. If there is but one brood or 

 only a feeble second brood this method would be more efficient in 

 Maine than where two broods occur. As most of the larvae escape 

 from the apples before they fall, th ; custom of gathering windfalls 

 to destroy this insect cannot prove effectual, though it is recom- 

 mended as a help. The apples should, however, not be allowed to 

 remain long on the ground. The}- harbor the larvae of other insects 

 which would be destroyed at the same time 



About the first of June fasten around the trunks of the trees 

 bandages of straw, cloth or paper. The larvae will seek these bands 

 to spin their cocoons. The bands should remain until after the 

 second brood spins and be examined for worms and cocoons every 

 few days. The bands should also be used when spraying is done as 

 a means of destroying the second brood should it appear. 



Barrels in which apples have been stored should be examined and 

 the eocoong destroyed. The natural enemies are few, though 

 ichneumon flies, ground beetles and other insects and insectivorous 

 birds, help keep them in check.
