Mining Moths on Pyracantha
Leaf miners are the larvae of moths that tunnel just under
the surface of leaves, they spend the winter tunneling through leaves until
spring then the larvae emerage and become months. As they feed, they make
distinctive winding trails or blotches on the leaves.
When the first sign of leaf miner assault becomes evident, you can soak
the leaves with neem or a nicotine spray. However, when you notice the damage,
it is already very late to take curative actions. Nevertheless, you should
immediately remove the affected leaves and clear the area beneath the shrubs of
all leaves and debris during the fall with a view to protect the plants from
being infected again. In fact, the damage caused by lilac leaf miners is more
aesthetic compared to physiological. S. vulgaris or the common lilac is most
vulnerable to invasion by leaf miners.
