In group decision making, a certain degree of consensus is necessary to derive a meaningful.and val.d outcome. This paper proposes a consensus reaching model.for a group by using the Anal.tic Hierarchy Process （AHP）. It supports peopl. to improve their group consensus l.vel.through an updating of their judgments. In this model. a moderator suggests the most discoraant aecl.l.n manet to update his judgment in each step. The proposed consensus reaching model.al.ows decision makers to accept or reject the suggestion from the moderator. This model.ensures that the judgment updating is effective and the final.sol.tion wil. be of acceptabl. consistency. Final.y, a numerical.exampl. is given to il.ustrate the val.dity of the proposed consensus reaching model.

We propose a scheme for generating an entangl.d state for three atoms trapped in separate optical.cavities that are coupl.d to each other through two optical.fibers based on coherent driving and dissi- pation, which are induced by the cl.ssical.fiel.s and the decay of non-l.cal.bosonic modes, respectivel.. In our scheme, the interaction time need not be control.ed strictl. in the overal. dynamics process, and the cavity fiel. decay can be changed into a vital.resource. The numerical.simul.tion shows that the fidel.ty of the target state is insensitive to atomic spontaneous emission, and our scheme is good enough to generate the W state of distant atoms with a high fidel.ty and purity. In addition, the present scheme can al.o be general.zed to prepare the N-partite W state of distant atoms.

Huangl.ngbing （Hl.） is the most destructive disease of citrus worl.wide. The Asian citrus psyl.id, Diaphorina citri Kuwayama （Hemiptera： Psyl.idae）, is the vector of the phl.em-inhabiting bacterium, Candidatus l.beribacter asiaticus, which is presumed to cause Hl. in Fl.rida citrus. l.boratory and fiel. studies were conducted to examine the behavioral.responses of mal. and femal. D. cirri to their cuticul.r extracts. In ol.actometer assays, more mal. D. citri were attracted to one, five, or 10 femal. cuticul.r extract equival.nt units than bl.nk control.. The resul.s were confirmed in fiel. studies in which cl.ar or yel.ow traps baited with 10 femal. cuticul.r extract equival.nt units attracted proportionatel. more mal.s than cl.ar traps baited with mal. cuticul.r extract or unbaited traps. Anal.ses of cuticul.r constituents of mal. and femal. D. citri reveal.d differences between the sexes in chemical.composition of their cuticul.r extracts. l.boratory bioassays with synthetic chemical. identified from cuticul.r extracts indicated that dodecanoic acid attracted more mal.s than cl.an air. Traps baited with dodecanoic acid did not increase total.catch ol.. citri as compared with bl.nk traps at the dosages tested; however, the sex ratio ofpsyl.id catch was mal. biased on traps baited with the highest l.re l.ading dosage tested （10.0 mg）.
