INJURIOUS INSECTS.

REMEDIES. 
Last summer was my first acquaintance with 
this pest and the application that I fully expected 
would keep it in check did not prove altogether 
satisfactory. In gardens, much can be done by 
gathering the eggs before the larvae hatch. If 
London purple or Paris green are used dry, one 
part should be put with not less than 100 parts of 
the dilutant, and I would recommend slaked lime as 
being the best for this. The application should be 
made very light or the poison will kill the leaves of 
the plants. If these poisons are used in water, 
there should not be more than one ounce of the 
poison to twelve gallons of water, and slaked lime 
should be added to the mixture to prevent the

burning of the leaves. It is probable that kerosene 
emulsion or insect powder thrown on the .larvae 
from the under side of the leaves would be useful, 
but these insecticides have not been tried as.yet. 
I hope to be able to recommend some 
thoroughly efficient remedy for this pest another 
year. 
This insect, in the beetle state, has a method 
of protection that is worthy of mention in this con¬ 
nection. If a beetle is disturbed it will draw up its 
legs and from each knee joint there will be ex¬ 
uded a small drop of a yellow liquid that has a 
very strong, disagreeable odor which, I have no 
doubt, gives the insect perfect immunity from the 
attacks of birds.
