Insects Injurious to the Apple.

processes separate and diverging outwards, hairy at their apices ; 

 the eyes are black and the wing cases and legs long, the former 

 pointed. This stage lasts 

 from two to three weeks, 

 the moths emerging from 

 the end of June into mid 

 August. The pupa may 

 sometimes be seen project- 

 ing from the dead shoot. 

 Now and again the red 

 lame leave the shoots 

 and pupate amongst the 

 dead leaves. The minute 

 differences of the larva? 

 and pupte of the two 

 species have not yet been 

 made out. 



Mr. W. Bear says the 

 attack becomes evident at 

 Hailsham in May (3). 



PKEVEXTIVE MEASURES. 



It is quite obvious that 

 there can be no remedy 

 for this pest, but we can 

 do much in the way of pre- 

 vention by hand-picking 

 the dead shoots before the 



moths emerge in June. This can only be done, of course, where 

 small trees are attacked, and it usually happens that it is only on 

 such trees that the attack takes place, but I have known large 

 bush trees attacked. The larvae may be killed by cutting off 

 attacked parts in winter, easily told by the characters previously 

 given (vide Fig. 84). 



Late spraying with arsenate of lead might prove beneficial, as it 

 would kill the young larv?e, which seem to feed first of all on the 

 leaves. Of course, care must be taken in regard to the fruit. The 

 trees should be washed as soon as the fruit is harvested ; a heavy 

 spraying should be given. 



The time to spray therefore must depend on the variety of apple 

 concerned. This is certainly worth giving a fair trial, as beyond
