Abstract
In 1995-96, a study was carried out in Eastern Sicily on the biology
and ethology of Aleurolobus teucrii Mifsud & Palmeti, that lives on Teucrium
fruticans L. (Labiatae). The whitefly has two yearly generations, with adults flying
in May-June and July-August; it overwinters in the nymphal stages, especially 3rd
and 4th instars, and its development only slightly slows down during the coldest
months. Natural mortality at pre-imaginal stages was quite modest throughout the
study. Parasitization by Encarsia olivina (Masi) (Hymenoptera Aphelinidae) was
frequently observed, though usually at moderate levels. Direct contro! of the
whitefly is not thought to be necessary at present, in spite of the increasing
commerciai interest in its host plant.
