138 AGRICULTURAL EXPERIMENT STATION. 



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

 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 larvae of all ages and cause the broods to lap over each 

 other. The second brood generally 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. 35G, that in this State 

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

 vations the past season indicate two broods, lapping over each other 

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

 ber and the first part of October. Larvae 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, about 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 of the first brood and the period of laying eggs. If 

 there is but one brood or onl}' a feeble second brood, this method 

 would be more efficient in Maine than where two broods occur. As 

 most of the larvre escape from the apples before they fall, the custom 

 of gathering windfalls to destroy this insect cannot prove effectual, 

 though it is recommended as a help. The apples should, however, 

 not be allowed to remain long on the ground. They 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 ban- 

 dages of straw, cloth or paper. The larvie 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 cocoons destroyed. The natural enemies are few, though ich- 

 neumon flies, ground beetles and other insects and insectivorous 

 birds, help keep them in check.
