Title: Protection of Mountain Laurel from Pyralid or Genista moth caterpillars
Answered by: Joe Marcus and Nan Hampton

QUESTION:

I have a Texas Mountain Laurel. Every year it is attacked by caterpillars. They form a bag for lack of a better word on the ends of the branches destroying the blooms for the following year. PLEASE HELP.

ANSWER:

The caterpillars on your Mountain Laurel (Sophora secundiflora) are probably the larvae of the Pyralid or Genista moth (Uresiphita reversalis). You can pick off the caterpillars and destroy them if you can reach them and/or Bt (Bacillus thuringiensis) applied to the tree should also take care of them.
