target of the firethorn leaf-miner moth is the
garden shrub Pyracantha. Scientists believe
that by tracking the spread of the insect, the
spread of other species as biological control
agents and genetically modified species might
be predicted. The Department of the Environ-
ment is spending £390,000 over three years on
the project. Sightings of the moth which
cause distinctive blistering on Pyracantha
leaves should be notified to Professor John
Lawton, Imperial College's Centre for
Population Biology, Ascot, Berkshire, SL5 7PY,
from whom a free pamphlet may be obtained.
