CYGON also works very well. You need to catch the crawlers as they hatch.
Try every five days three times,then every month.

Any new wisdom on boisduval scale on cattleyas? I've read that
acephate (Orthene), kinoprene (Enstar II), and imidacloprid (Merit)
are all pretty effective administered in 2-3 treatments several weeks
apart.

Any suggestions for timing as to season or treament interval would
also be useful.

Thanks.

Jim
