You have undoubtedly acquired a population of 'White Moth' or 'Whitefly'
as it is called in Britain - one of the major greenhouse pests. "The adults
are like miniature moths with white wings, and the larvae are small scale-
like creatures, generally greenish in colour, which feed without movement
on the undersides of the leaves." (source, would you believe it, 'Pears
Cyclopaedia, 84th edition' - couldn't locate a reference in any of my garden
books).  Control recommended in Pears is lindane or malathion spray.  My
recommendation would be to burn the plants (or give them to someone you
dislike).  U. of T. Botany department's greenhouse superintendent might be
able to offer advice.
