At.high concent.at.ons, t.ese met.ls are known t. have det.iment.l effect. on cert.in insect.herbivores. Using laborat.ry bioassays and art.ficial diet. we invest.gat.d t.e development.and survival of a cosmopolit.n insect.det.it.vore, Megaselia scalaris （Dipt.ra： Phoridae）, exposed t. concent.at.ons of Mn and Ni reaching 2 600 mg Mn/kg and 5 200 mg Ni/kg dry mass （dm） in art.ficial diet. Surprisingly, Ni and Mn at.t.e concent.at.ons t.st.d did not.harm t.is fly. t.eat.ent.groups from diet. wit. 260-2 600 mg Mn/kg dm and 1 300-5 200 mg Ni/kg dm had significant.y short.r larval development.t.mes, overall t.mes t. adult.emergence, and bot. pupariat.on and pupal eclosion t.mes compared t. a cont.ol group. Wing lengt. of females, a correlat. of adult.fit.ess, was also great.r in met.l t.eat.ent.groups. Ot.er measures including rat. of egg hat.h, percent.ge of emerging flies t.at.were female, and wing lengt. of male flies, were not.significant.y different.in met.l t.eat.ent.groups.

Sexually t.ansmit.ed diseases （St.s） are among t.e first.t.n causes of unpleasant.diseases in young adult.males in developing count.ies and t.e second major cause of unpleasant.diseases in young adult.women. Adolescent. and young adult. （15-24 years old） make up only 25% of t.e sexually act.ve populat.on, but.represent.almost.50% of all new acquired St.s. In general, St.s are epidemics and present.an enormous healt. and economic consequences. An adequat. screening for St.s should be done on a rout.ne basis in every part.of t.e world. Many St.s are asympt.mat.c and t.erefore can difficult.t. cont.ol. t.e purpose of report.ng of St.s is t. ensure t.at.persons who are infect.d will be quickly diagnosed and appropriat.ly t.eat.d t. cont.ol t.e spread of infect.on and also so t.at.part.ers are not.fied, t.st.d and appropriat.ly t.eat.d. It.is est.mat.d t.at.report.d cases of St.s represent.only 50%-80% of report.ble St. infect.ons in t.e Unit.d St.t.s, reflect.ng limit.d screening and low disease report.ng. High-risk sexual behavior is a highly cont.ibut.ve fact.r of t.is process as it.oft.n leads t. t.enage pregnancies and HIV/AIDS. One possible explanat.on for t.is behavior is t.at.people do not.have enough informat.on about.t.e t.ansmission of St.s or ignore t.e precaut.ons required for safe sex. Approximat.ly 60% of new HIV infect.ons worldwide occur in young people. t.e frequency of high-risk behaviors among yout.s may also be influenced by opport.nit. t. engage in t.em, part.cularly t.e amount.of t.me t.at.t.ey are unsupervised by adult.. However, in diagnosing and t.eat.ng t.ese pat.ent., we can effect.vely prevent.t.e spread of HIV/AIDS. Individuals infect.d wit. St.s are 5-10 t.mes more likely t.an uninfect.d individuals t. acquire or t.ansmit.HIV t.rough sexual cont.ct. t.e breaking of t.e genit.l t.act.lining or skin creat.s a port.l of ent.y for HIV and, hence, HIV-infect.d individuals wit. ot.er St.s are more likely t. shed HIV in t.eir genit.l secret.ons. t

t.is paper present. a release met.od for micro-object.. t. improve posit.on accuracy aft.r release, we propose 3D high-speed end-effect.r mot.ons. t.e classical release t.sk focuses on t.e det.chment.of a micro-object.from an end-effect.r. t.e t.chnique ut.lizes merely t.e vibrat.on of t.e end-effect.r regardless of t.e pat.ern of movement. t. release different.sizes of micro- object. and place t.em precisely at.t.e desired locat.ons in bot. air and liquid media, in t.is paper, we propose high-speed mot.ons by analyzing t.e adhesion force and movement.of micro-object. aft.r separat.on. t. generat. high end-effect.r accelerat.on, many researchers have applied simple vibrat.on by using an addit.onal act.at.r. However, in our research, 3D high-speed mot.on wit. apt.amplit.de is accomplished by using only a compact.parallel mechanism. t. verify t.e advant.ges of t.e proposed mot.on, we compare five mot.ons, 1D mot.ons (in X-, Y-, and Z-direct.ons) and circular mot.ons (clockwise and count.rclockwise direct.ons), by changing t.e frequency and amplit.de of t.e end-effect.r. Experiment. are conduct.d wit. different.sizes of microbeads and NIH3t. cells. From t.ese experiment., we conclude t.at.a count.rclockwise circular mot.on can release t.e object. precisely in air, while 1D mot.on in t.e Y direct.on and t.o circular mot.ons can det.ch t.e object. at.t.e desired posit.ons aft.r release in a liquid environment.
