The effect of ma.netic field on the pla.e vibra.ions for a. ela.todyna.ic orthotropic sphere is studied. Equa.ions of ela.todyna.ic problems of the orthotropic hollow sphere in terms of displa.ement a.e solved. The numerica. results of the frequency equa.ions in the presence of ma.netic field a.e discussed a.d shown gra.hica.ly. Compa.-isons a.e ma.e with the result in the presence a.d a.sence of ma.netic field in the ca.e of orthotropic sphere. The results show tha. the effect of ma.netic field is very pronounced.

Experimenta. work wa. conducted a. two a.ia.ies loca.ed in Irbid district a.d in Shuna.North, Jorda., during the yea.s 2004-2006. The a.ms of these investiga.ions were to estima.e the sea.ona. cha.ges in the infesta.ion ra.es of the bee louse （Bra.la.sp.） a.d to develop a. ea.y a.d ra.id method of estima.ing the infesta.ion ra.e on workers with bee Bra.la. Two ma.or honey bee subspecies a.e rea.ed in Jorda.; a.is mellifera.ca.nica.a.d a.is mellifera.syria.a.were used in this study. The results showed tha. the infesta.ion ra.e bega. to increa.e ra.idly in Ma., rea.hing the sea.on＇s ma.imum ra.e of 16.2%, 15.8% a.d 17.4% fora. m. ca.nica.a.d 22.6%, 23.9% a.d 22.9% fora. m. syria.a.in December of 2004, 2005 a.d 2006, respectively. The ma.imum a.ult numbers of bees were found in a.ril a.d June, wherea. the minimum for the yea. wa. in Ja.ua.y in both honey bee subspecies colonies during the study period. The a.tua. popula.ion of the bee louse could be estima.ed by counting the da.ly dropped lice a.d multiplying by a.fa.tor of 158. This fa.tor is va.id for the experimenta. colonies of both subspecies kept for 3 yea.s under semi-a.id Mediterra.ea. conditions.
