MEAI/VT BUG (Dactylopius adonidum). 



This is an insect which is becoming very prevalent in 

 vineries. It is of foreign introduction, and now quite at home 

 in our plant houses. The white, mealy substance from which 

 it is named is almost proof against water. It instantly melts 

 when drenched with methylated spirits. When once it is 

 produced it spreads rapidly from the branches to the bunches, 

 and when on the latter, cannot be destroyed without damaging 

 the fruit. As the season advances, the genial warmth of the 

 vineries will draw them out of their winter quarters, which 

 often are under the back of the vine. The best way to destroy 

 them is to touch them with a camel hair brush, dipped in 

 methylated spirits. This causes instant death, and therefore, 

 proved to be a most effectual remedy for mealy-bug. Also 

 fumigate the house with XL ALL three or four times in succes- 

 sion after the fruit is cut. As a winter dressing for vines 

 infested with mealy bug, paint the canes with gas tar mixed 

 with half a peck of dry clay and half a peck of lime, to half a 

 pint of the tar ; mix thoroughly by placing on a fire and 

 adding as much water as will make the whole about the con- 

 sistency of thick cream. Apply when cold. 



The most harmless for all remedies for bug is to scrub the 

 vines well with warm water and a little soft soap, and dress 

 them every day for a week with Gishurst Compound. Paint 

 the houses, first having them well washed. Limewash the 

 walls, using hot lime. Remove one inch from the whole of the 

 surface of border. But it may take even a year or two to rid 

 the vineries of this dreaded foe. 



THE VINE WEAVER (Otiorhinchus Sulcatus). 



This weavel is not very common, but sometimes it does a 

 great deal of mischief before it is noticed. It comes out of its 

 hiding place during the night and eats through the yonug 

 leaves and growing points of vines, and thus greatly cripples 

 their growth. The shoots thus damaged should at once be 

 cut back to the sound part. The best way to destroy them is 

 to go quietly into the vinery at night and spread a white paper
