Overview

Excerpt from The Review of Applied Entomology, Vol. 8: Series An: Agricultural As a remedial measure spraying the plants with arsenical sprays as soon as the beetles appear is suggested. It is also easy to collect the larvae and the beetles in various ways. Collection must be carried out during warm and sunny weather, when the beetles are active, and can be effected either with nets or with a funnel made of sheet iron with a bag tied at the bottom. A useful apparatus consists of 4 or 5 wooden boards attached by sticks 12 - 16 inches long to a pole about 6 ft. 6 ins. Long the boards are covered with tar and a wire is fastened in front of the pole. The pole is carried through the fields by two men, so that the boards are drawn between the rows of plants, and the larvae and beetles, disturbed by the wire touching the plants, drop and are caught on the boards. The destruction of cruciferous weeds is also a very important measure against this beetle, and the keeping of bees has proved very effective, since the bees disturb the beetles when visiting the flowers, often dislodging them and thus lessening the damage done by them to a considerable degree.
