Diasins amygdall of Tryon. On inquiry it was found that the greater 
number of the plants of this particular batch (100) had been planted 
outdoors since the time of their arrival ; and, as the examination proved, 
the insects were not in any way affected by their change of climate, but 
appeared in a perfectly healthy condition. Information was at once 
forwarded to the correspondent as to the serious nature of the pest, with 
a request that the plants be at once destroyed. This, however, was not 
carried out ; but measures were taken to destroy the insects by dipping 
the whole 100 plants in a hot paraffin emulsion, in the hope the insects 
would not survive such drastic treatment. 
And so the matter rested until June 3, when the correspondent again 
informed the writer that a recent examination of the plants had been 
made, when it was found that the insects were still living, and it was 
thought another application of the insecticide would have completely 
destroyed them ; but instead of temporising the plants were all burnt.

This was much the wiser plan, as we have the satisfaction of knowing 
that the insects on this particular batch of plants are completely destroyed, 
and this, too, before the young ones (larvie) had time to hatch and 
migrate to other plants. Into whose hands the remaining plants have 
fallen has yet to be discovered, and we earnestly appeal to all those 
who purchased Japanese Cherries from the same consignment to at once 
communicate with us, at the same time sending examples of the insect 
for identification. 
But numbers of foreign nurserymen import Japanese Cherries, &c., 
and, in order to prevent a repetition of this, the most stringent measures 
should be taken to prevent any further importations of infested plants 
into this country, which can only be done by an inspection of them on^ 
arrival, and before they have been dispersed throughout the country.
