Some time ago I called the attention of the Society to
the devastation created by the larvae of the codlin moth in
the orchards in the Northern parts of the Colony. It has
appeared in the orchards in the vicinity of Hobart Town during
the last year to an extent that must alarm all those concerned
in apple growing, and this is an extensive industry
representing an export trade of not less than £40,000 a year.
On the former occasion I pointed out something of the history and
habits of the moth and its larvve, but the all important question
now is, how it can best be destroyed? After the moth has deposited
an egg in the eye of the young apple, and it seldom deposits more
than one egg in an apple, the egg hatches and the young creature
eats its way through the tender skin of the apple at its eye, into
the substance. The orchardist is not aware of its presence till
he sees a dark spot on his apple, and then a hole from which the
creature expels small grains of excrementitious matter which cover
the orifice of the hole. It feeds on the pulp and attacks the pips,
the most vital part of the apple, which then falls and the creature
escapes through the orifice which it has made. Its exit is rapid,
and many apples may be examined in the morning, which have
fallen during the night, before one is found in which a grub remains.

In 1843 the Horticultural and Botanical Society of Van Diemen's Land was founded and became the Royal Society of Van Diemen's Land for Horticulture, Botany, and the Advancement of Science in 1844. In 1855 its name changed to Royal Society of Tasmania for Horticulture, Botany, and the Advancement of Science. In 1911 the name was shortened to Royal Society of Tasmania.
