Orchard and Bush Fruit Pests.

detected, and owing- to their gregarious nature it is easy to cope 

 with them. The damage done to cherry foliage was reported as 

 severe from near Sittingbourne. 



Grey Trident i^/^//;.— Although probably not of much account, 

 it is of interest to note that the grey trident moth {Acronycta 

 tridens) has attacked fruit trees, both plum and apple, near 

 Liverpool and in Worcestershire, at the former place in sufficient 

 numbers to do considerable harm. 



Apple Clear- Wifig Borer. — Apple trees in the neighbourhood 

 of Croydon were damaged by the clear-wing borer {Aegeria 

 myopaeforinis), the larvae eating into the wood of the small 

 stems and even twigs of several varieties of apples. Judging 

 from the number sent they must have been doing much damage 

 to the trees. Smearing the trees with some noxious compound 

 is all that can be done in such attacks, except removal of the 

 larvae by means of a knife or wire. 



Winter Moth. — The v/inter moth {Cheiniatobia brinnatti) was 

 not as harmful as usual in 1906. Where grease-banding has 

 been followed this pest has been reduced to such an extent that 

 it is now of no great account. No bad attack seems to have 

 taken place generally in Kent, the only instances reported where 

 serious damage was done being in Worcestershire, where four 

 orchards, one of cherry and the others of apples, were badly 

 defoliated. In all these cases there had been no attempt at 

 banding or spraying. 



Bud Moth. — The bud moth {Hedya ocelland) does not 

 appear to have been as abundant as usual, but it was com- 

 plained of in one locality in Kent and from another in Wor- 

 cestershire. Specimens have also been bred from material sent 

 from North Devon. 



PitJi Moth. — Only one reference has been made to the pith 

 moth {Blastodaena viiiolentella, H. Sc.) from Kent This 

 serious pest in young plantations was formerly known as 

 Laverna atra, Hawth. Professor Carpenter, who records its 

 presence in Ireland,* shows that previous identifications have 

 been wrong, and that the Laverna atra which has been recorded 

 from hawthorn berries is distinct. The difference given is said
