Two Troublesome Beetles.^ — Botanical Jl., London, v, no. 5, September 

 1917, p. 73. 



Byturus tomentosus, F. (raspberry beetle) is a serious pest of rasp- 

 berries, blackberries and loganberries, while the adults also feed on 

 hawthorn, apple and pear blossoms, appearing in late spring and 

 early summer, destroying some blossoms and ovipositing in others. 

 Winter is passed in the pupal stage, either in the ground or on the 

 canes or supporting stakes. In this stage large numbers can be 

 killed by burning the cuttings from the autumn pruning, and the 

 adults may be destroyed by shaking the canes on dull days and 

 collecting the beetles on tarred boards. The ground may be treated 

 with paraffin and ashes, or with soot and lime in the early spring, 

 while spraying mth lead arsenate at the time the blossoms open has 

 proved effective. As this beetle may migrate to raspberries from 

 wild blackberries, any of these growing in the vicinity should be 

 destroyed. 



Bcdaninus nucum, L. (nut weevil) attacks the cob, filbert, hazel and 

 oak, the single egg being laid in a hole bored in the young nut and 

 being pushed well into the interior. The larva escapes and hibernates 

 in the soil, pupation taking place in early spring, at which time the 

 insects may be, exposed to the attacks of birds by turning over the 

 ground beneath the trees. When the adult weevils appear about 

 midsummer, they may be destroyed by shaking the trees over tarred 

 boards.
