hand when pests are permitted to increase at will (through the 
careless neglect to gather up and burn all infested produce in the 
field ) we shall have not only double work to perform, but all this 
will tend to discourage the small farmer and other branches 
advocated by the Governor, such as field demonstrations for the 
homesteader and the opening of markets, which are to be taken 
up by the Federal Experiment Station. 
If the funds set aside for inter-island inspection can be used 
for this work, I believe that the Board of Agriculture has the 
power, with the consent of the Governor, to pass the necessary 
regulations to cause the destruction of infested and worthless 
produce in the fields and gardens and markets. 
The Mediterranean fruit fly is proving a great pest. We even 
found it attacking green peppers and when island fruits are out 
of season the insect might take to other fruits and vegetables 
in its struggle to survive. The melon fly has been a great menace 
for many years and has been reared from oranges. All this goes 
to show that unless we can begin to cope with these two pests in 
some way, pending the finding of their natural enemies, cultural 
matters will become worse as time goes on. Individuals are will- 
ing to destroy all infested produce, but the constant complaint is 
that the neighbor won't do anything. In California the man who 
neglects clean culture and wilfully breeds pests is prevented from 
doing so by certain laws which are enforced by field inspectors. 
Why cannot this be done here in Hawaii? 
Why should the melon grower be allowed to leave infested 
melons lying about his field or why should the pineapple grower 
be permitted to allow old discarded plants, badly infested with 
mealy bugs, to remain stacked up along the roadside?

Superintendent of Entomology.
