The tomen.ose cochin.al scale in.ect, Dactylopius tomen.osus （Lamarck）（Hemiptera： Dactylopiidae）, is an.importan. biological con.rol agen. again.t in.asive species of Cylin.ropun.ia （Caryophyllales： Cactaceae）. Recen. studies have demon.trated that this scale is composed of host-affiliated biotypes with differen.ial host specificity an. fitn.ss on.particular host species. We in.estigated gen.tic variation.an. phylogen.tic rela-tion.hips amon. D. tomen.osus biotypes an. proven.n.es to examin. the possibility that gen.tic diversity may be related to their host-use pattern. an. whether their phylogen.tic relation.hips would give in.ights in.o taxon.mic relatedn.ss of their host plan.s. n.cleotide sequen.e comparison.was accomplished usin. sequen.es of the mitochon.rial cytochrome c oxidase I （COI） gen.. Sequen.es of in.ividuals from the same host plan. within.a region.were iden.ical an. characterized by a un.que haplotype. In.ividuals belon.in. to the same biotype but from differen. region. had similar haplotypes. However, haplotypes were n.t shared between.differen. biotypes. Phylogen.tic an.lysis grouped the mon.phyletic D. tomen.osus in.o 3 well-resolved clades of biotypes. The phylogen.tic relation.hips an. clusterin. of biotypes correspon.ed with kn.wn.taxon.mic relatedn.ss of their hosts. Two biotypes, Fulgida an. Mamillata, tested positive for Wolbachia （α-Proteobacteria）, a common.en.osymbion. of in.ects. The Wolbachia sequen.es were seren.ipitously detected by usin. in.ect-specific COI Dn. barcodin. primers an. are most similar to Wolbachia Supergroup F strain.. This study is the first molecular characterization.of cochin.al biotypes that, together with Wolbachia sequen.es, con.ribute to the better iden.ification.of the biotypes of cochin.al in.ects an. to the biological con.rol of cacti usin. host-specific biotypes of the scale.

They were derived from differen. magma series: the gabbro was derived from tholeiitic magma series with higher TiO2, REE abun.an.e an. Fe3+/Fe2+ ratio ; n.rite-gabbro was derived from calc-alkali magma series with lower TiO2, Fe3+/Fe2+ ratio an. REE abun.an.e an. much lower HREE abun.an.e, which suggests that the source of the n.rite-gabbro magma was deeper an. con.rolled by eclogite facies. Geochemical characteristics of both pluton.c rocks are similar to those of islan.-arc basalts, such as relatively high con.en.s of Ba, Pb an. Sr an. relatively low con.en.s of n., Zr an. n.*** Sr, n. isotopic characteristics of the Lajimiao n.rite-gabbro complex are similar to those of ophiolites. Its εn. values are con.tan., about+2; whereas εst values have wide variation.from - 6.4 to +31.2 an. positively correlate with n.2O, H2O+ an. CO2 con.en.s an. the Fe3+/Fe2+ ratio. The εn.- n./Th, εn.- La/n. an. εn.-Ba/n. diagrams clearly show that there were sign.fican. compon.n.s of terrigen.us sedimen.s in.the man.le source of the Lajimiao n.rite-gabbro complex. It suggests that large amoun. of sedimen.s had been.carried in.o the man.le by the subducted an.ien. Qin.in. sea plate durin. the Palaeozoic.
