On the Codlin moth, (Carpocapsa pomonella)

For some years past the apple orchards in the northern parts of this colony have almost ceased to be productive.
Every grower of apples there knows how liable his fruit is to be worm-eaten; he finds basketsful of windfalls even in the calmest weather, and he is aware that the cause of the loss is a small grub which has fed upon the pulp of the fruit. The ravages of this insect are not wholly confined to the apple, but have in some cases extended to crops of pears. This grub has made its appearance in some of the gardens in the vicinity of Hobart Town; it is said to have been observed here three years ago, and up to the present time it has not been the cause of loss to any serious extent in the Southern orchards. The history of these grubs, and how and when they get into the apple may not be generally known.
