The preference-performance relati.nshi. i. plant-i.sect i.teracti.ns i. a cen- tral theme i. evoluti.nary ecology. Among many i.sects, eggs are vulnerable and larvae have li.i.ed mobi.i.y, maki.g the choi.e of an appropri.te ovi.osi.i.n si.e one of the most i.portant deci.i.ns for a female. We i.vesti.ated the evoluti.n of ovi.osi.i.n preferences i. Drosophi.a melanogaster mei.en and Drosophi.a si.ulans Sturtevant by arti.i.i.lly selecti.g for the preference for 2 natural resources, grape and qui.ce. The mai. fi.di.g of our study i. the di.ferenti.l responses of D. melanogaster and D. si.ulans. Although preferences evolved i. the experi.ental populati.ns of D. melanogaster, responses were not consi.tent wi.h the selecti.n regi.es appli.d. i. contrast, responses i. D. si.ulans were consi.tent wi.h expectati.ns, demonstrati.g that thi. speci.s has selectable geneti. vari.ti.n for the trai.. Furthermore, crosses between D. si.ulans di.ergent li.es showed that the geneti. factors i.volved i. grape preference appear to be largely recessi.e. i. summary, our arti.i.i.l selecti.n study suggests that D. melanogaster and D. si.ulans possess di.ferent geneti. archi.ectures for thi. trai..

Heavy metals were analyzed i. di.ferent foods crops, mi.k, meat and blood samples collected from di.ferent age group subjects such as chi.dren （1–12 years）, adolescent （12–18 years）, adults （18–45 years） and old age （above 45 and 55 years for males and females, respecti.ely） from polluted and relati.ely less polluted areas. The results revealed that the consumpti.n of contami.ated food crops, meat and mi.k have si.ni.i.antly i.creased the concentrati.ns of selected metals i. the human blood. Cu, Zn and mn concentrati.ns were si.ni.i.antly hi.her （p 0.05） i. the blood samples collected from the polluted area as compared to control area. Old people had accumulated hi.h concentrati.ns of metals as compared to the younger ones wi.hi. the same area. males accumulated hi.her concentrati.ns of metals as compared to females.

i. thi. study, the gamma radi.ti.n shi.ldi.g features of several envi.onmentally fri.ndly materi.ls were i.vesti.ated. For thi. purpose, several attenuati.n parameters, such as the mass attenuati.n coeffi.i.nt (l=q), radi.ti.n protecti.n effi.i.ncy (RPE), and effecti.e atomi. number (Zeff) were determi.ed experi.entally and compared wi.h numeri.al data obtai.ed usi.g Wi.XCom software. i. the measurements, the emi.ted gamma photons were counted by a gamma spectrometer equi.ped wi.h an HPGe detector usi.g 22Na, 54mn, 57Co, 60Co, 133Ba, and 137Cs radi.acti.e poi.t sources i. the energy regi.n of 81–1333 keV. The obtai.ed results i.di.ate that the l=q and RPE values of the samples decrease wi.h an i.crease i. photon energy. The experi.ental values are i. good agreement wi.h those obtai.ed usi.g Wi.XCom software. The RPE and Zeff results show that among the studi.d materi.ls, the NaY0.77Yb0.20Er0.03F4 sample has the best gamma radi.ti.n shi.ldi.g effecti.eness.
