THE BLUE LIGHT
NEWS FOR ARTICHOKE MOTHS. Science, taking note that many insects have favourite colours, has come to the rescue of the vineyards and market gardens of California. The growers are much plagued by the grape leap-hoppers and the artichoke plume-moths, and both these pests are attracted by blue light. Consequently in the vineyards and artichoke fields blue electric lamps enclosed in electrically-charged wire cages are set at intervals.

The leaf-hopper is disappearing, and the destruction of artichoke heads lias falen from one in four to one in thirty.
