HARMFUL INSECTS lays 
means should be taken to lessen its ravages. The following 
are amongst the best methods of destroying it. 
Before the larvae begin to appear, bands made from old 
bags should be tied round the trunks of the trees near the 
bottom as well as round the larger branches. The former 
will trap the larvae as they begin to crawl up the trunk 
and the latter wll catch those crawling back along the 
branches. ‘These traps should be examined every week or 
ten days, and all the larvae destroyed. 
The apples which fall off if they contain codlin-moth 
larvae should at once be collected and destroyed. 
The ground underneath and around the trees should be 
kept free from rubbish of all kind ¢.g., dead leaves and 
branches. 
The bark of infected trees should be scraped and the 
scrapings collected and burnt. 
The trees, when the apples are forming should be 
sprayed witha mixture of kerosene oil and soft soap. This 
to a large extent will prevent egg-laying—but as the eggs 
are not all laid at the same time, several sprayings are | 
necessary. 
A large number of injurious insects are to be found in 
all countries—our own islands supporting a formidable 
array of these destructive creatures. 
Though it is highly desirable, indeed necessary, that 
those who are engaged in fighting these pests should have 
an intimate knowledge of their appearance and life-history, 
and though, moreover, many of the pupils in our schools 
may afterwards find such knowledge useful, yet it is 
beyond the scope of this book to enter into the subject 
with the necessary fulness of detail. For this the student 
is referred to Miall’s Injurious and Useful Insects (Geo. Bell 
& Son, 3s. 6d.), and to Hudson’s works on New Zealand 
Entomology.
