cut off and destroyed. Against the raspberry borer [Pennisetia hylaei- 

 formis] the collection in July of the pupae in the canes of the 

 previous year is advised. Collection of the buds infested by the 

 raspberry weevil [Anthononius rubi] and of the weevil itself is the 

 only available measure. As the larvae of another weevil, Polydrosns 

 calcamtus, live in the ground, the latter should be dug up and well 

 hmed in winter ; the beetles may be jarred off in the morning, this 

 being also the only remedy against the raspberry beetle {Byturus).

This circular deals with the value and practical possibilities of bird 

 protection in Germany as a means of checking injurious insects.

In view of the rise in price of mole skins the Imperial German Bio- 

 logical Institute has drawn attention to the services rendered by the 

 mole, which include the destruction of many injurious insects. Further 

 investigations on its food are being made. A law was passed in Bavaria 

 in 1920 forbidding the destruction of moles except in enclosed gardens.

 p. 54. 



A devastating outbreak of the beet leaf bug [? Piesnia capitata, 

 Wolff] is reported from many parts of Anhalt, fodder and sugar-beet 

 being severely attacked. The eggs are laid at the end of May, usually 

 on the undersides of the leaves of beet seedlings. In seven to fourteen 

 days the larvae appear, and develop into adults in one month or six 

 weeks. Measures are not practicable against the adults, which hibernate 

 in woods, bushes, meadows and grass edges. Beet should not be grown 

 near these winter quarters, and must be drilled as late as possible, 

 never before mid-May. Stable manure should not be used after the 

 preceding autumn, and it must be ploughed in deep. Powdered quick- 

 hme should be scattered in spring in the beet fields, which should be 

 rolled as long as the young plants are able to survive the process, as 

 this crushes the soft eggs and very young larvae. Quicklime may be 

 used when the plants are growing, but must not be allowed to touch 

 them. A recurrence of this outbreak is expected in 1923.

Tanymecus palliatus, F., has begun to attack the foliage of sugar- 

 beet in Pomerania. This weevil normally lives on nettles. It is, 

 however, a recognised pest of sugar-beet in Hungary and parts of 

 Russia.
