Previously the search for pulsating pre-main sequence (PMS) stars in young open clusters resulted in the successful discovery of several new PMS pulsators using the CTIO 0.9m telescope. Pulsating PMS stars are key objects to study stellar evolution in connection with asteroseismology. Hence, the newly detected pulsation frequencies have triggered the development of non-radial pulsation theory for such young stars and allowed for the first time to identify non-radial oscillations in a PMS star. Although the number of known PMS pulsators has already increased to 25, it is still only possible to make a first guess on the location of the PMS instability region. We therefore apply for photometric time series observations of the young open cluster NGC 6531, which contains several PMS A-F type members, hence providing a high possibility to discover new PMS pulsators. Observations of the PMS pulsator HD 142666 with the MOST satellite are scheduled for May and June 2007. Simultaneous ground-based UBVRI photometry taking only a fraction of each night will allow to study the UX Ori phenomenon typical for PMS stars.
