1 1 o Second Report on Economic Zoology. 
Mealy Bug in Vine. 
A correspondent wrote from Great Staugkton, stating that 
Mealy Bug has got on to the vines from imported plants, and asking 
advice. The following was sent : — 
“ The best thing your gardener can do is to go carefully over the 
vine and paint the patches where the Mealy Bug has taken up its 
abode with a fine brush dipped in turpentine, which soon kills them. 
It should be done at once, and again when all the grapes are cut. 
The best plan is to fumigate the house with hydrocyanic acid gas, 
but it is a trouble and wants doing very carefully, and in a small 
vinery I think going over by hand will be just as successful.” 
Disease in Begonias and Gloxinias. 
Some Begonia and Gloxinia leaves sent from Milford, near 
Godaiming, were blotched and diseased ; the correspondent stated 
many were thus attacked and spoilt. 
The damage was evidently due to insects, as the punctured tissue 
is plainly noticeable. Two insects were present, but only very few 
specimens : viz. (1) a yellow Thrips with black wings ; and (2) a 
single Aphis in larval state. 
I fancy the damage is due to the Thrips , which is a very small 
species not known. 
Under the circumstances it is well to syringe with plenty of 
water with a little tobacco extract in it, and an ounce of soft soap to 
every two gallons of water.
