Excerpt from Ninth Annual Report of the State Entomologist of Montana

The Cabbage Butterfly (pontia rupac Linn). Common as the cabbage butterfly is, the gardeners Of the State are very little informed regarding the method Of controlling it. Many fear to spray their cabbages with arsenicals. Thinking that to do so would make them poisonous. It has been demonstrated by a number of experiment stations besides this one, that sprayed cabbage may be eaten with safety and we have shown that this insect may be controlled if a small amount Of soap is added to the spraying solution, thereby making the arsenical adhere to the waxy foliage of the cabbage.

The Diamond-back Moth (plutella maculipennis Curtis). This small insect probably stands third as a cabbage pest in Mon tana and is a very serious one. Is so small that it almost escapes attention, yet if present In large. Numbers it does much to check the growth Of the cabbage. It is an introduced species which has found its way all through the United States.
