Nicotinic a.etylcholine receptors （na.hRs） a.e the ta.gets of.neonicotinoids a.d spinosa.s, two insecticides used in orcha.ds to ef.ectively control codling moth, Cydia.pomonella.（L.）（Lepidoptera. Tortricida.）. Orcha.dists in Wa.hington Sta.e a.e concerned a.out the possibility of.codling moth f.eld popula.ions developing resista.ce to these two insecticides. In a. ef.ort to help mitiga.e this issue, we initia.ed a.project to identif. a.d cha.a.terize codling moth na.hR subunits expressed in hea.s. This study ha. two ma.n goa.s; （i） identif. tra.scripts f.om a.codling moth hea. tra.scriptome tha. encode f.r na.hR subunits, a.d （ii） determine na.hR subunit expression prof.les in va.ious lif. sta.es of.codling moth. f.om a.codling moth hea. tra.scriptome, 24 tra.scripts encoding f.r 12 puta.ive na.hR subunit cla.ses were identif.ed a.d verif.ed by PCR a.plif.ca.ion, cloning, a.d sequence determina.ion. Cha.a.teriza.ion of.the deduced protein sequences encoded by puta.ive na.hR tra.scripts revea.ed tha. they sha.e the distinguishing f.a.ures of.the cys-loop liga.d-ga.ed ion cha.nel superf.mily with 9 α-type subunits a.d 3 β- type subunits identif.ed. Phylogenetic a.a.ysis compa.ing these protein sequences to those of.other insect na.hR subunits supports the identif.ca.ion of.these proteins a. na.hR subunits. Sta.e expression studies determined tha. there is clea. dif.erentia. expression of.ma.y of.these subunits throughout the codling moth lif. cycle. The inf.rma.ion f.om this study will be used in the f.ture to monitor f.r potentia. ta.get-site resista.ce mecha.isms to neonicotinoids a.d spinosa.s in tolera.t codling moth popula.ions.
