Abstract:XANTHONIA DECEM-NOTATA Say, previously unrecorded in economic literature, has been very destructive to the apple in one district in Maine.
It has been recorded for a long time as an unimportant leaf feeder on the oak, beech, and elm. The beetle has a general distribution thruout the Eastern United States and Canada and has been taken as far west as Texas.
In the infested region in Maine the adult beetles migrate from other host plants to the apple in September and in the course of two or three weeks they may ruin the market value of the entire crop. The appearance of the fruit is spoiled by the abundant shallow feeding punctures scattered over the surface.
The trouble has been present in the same orchard for sixteen years and has gradually increased in severity. This season from 75 to 90% of the grower's Russet apple crop was injured.
The beetles, on the apple trees, were collected in tightly curled dry leaves during the day. Observations in the laboratory and orchard suggest that they are night feeders because they are characteristically hidden by day.
Two new host plants, besides the apple, are recorded as a result of feeding experiments. They are the wild raspberry, Rubus strigosus, and the linden, Tilia americana.
