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.

Primary parasitoids of red scale （Aon.diella auran.ii） in.Australia an. a review of their in.roduction. from Asia

In.ect Scien.e 2017年第1期24卷 150-168页

作者： Han. T. Dao G. An.rew C. Beattie robert spooner-hart Markus Riegler Paul Holford Un.versity of Western.Sydn.y Penrith NSW 2751 Australia Plan. Protection.Research In.titute Chem Tu Liem Hanoi Vietnam

We used morphological an. molecular differen.es to con.irm the iden.ities of red scale （Aon.diella auran.ii） an. yellow scale （A. citrin.）, an. their primary parasitoids, in.Australia. An.exten.ion.to the distribution.of yellow scale was con.irmed. Six primary parasitoids of red scale were iden.ified： Aphytis chrysomphali, A. lin.n.n.n.is, A. melin.s, Comperiella bifasciata, En.arsia citrin., an. E. pern.ciosi. With the exception.of A. lin.n.n.n.is, these parasitoids, an. a species of Aphelin.s, were detected in.association.with red scale durin. studies in.citrus orchards in.coastal n.w South Wales between.2009 an. 2012. Two races ofA. melin.s were recorded： on. from the In.ian.Subcon.in.n., the other previously on.y recorded in.Chin.. The studies, an. reviews of historical records, led us to con.lude that 4 parasitoids, A. lin.n.n.n.is, C. bifasciata, an. both species of En.arsia, were presen. in.Australia before successful or un.uccessful formal in.roduction. between.1902 an. 1970. The A. melin.s race previously recorded in.Chin. may also have been.presen. before the In.ian.Subcon.in.n. race was formally in.roduced in.1961. We suggest the possibility that the n.tural distribution.of some of the parasitoids may in.lude East an. Southeast Asia, an. parts of Australasia. We foun. n. reports of n.tive armored scales bein. recorded on.species an. hybrids of Citrus in.roduced to Australia, an. n. reports of in.roduced armored scales bein. recorded on.n.tive Rutaceae, in.ludin. 6 species of Citrus. However, we subsequen.ly recorded yellow scale on.Geijera parviflora, a n.tive rutaceous tree.

Tran.cription.factor n.tworks have evolved in.order to con.rol, coordin.te, an. separate, the fun.tion. of distin.t n.twork modules spatially an. temporally. In.this review we focus on.the MYC n.twork （also kn.wn.as the MAX-MLX n.twork）, a highly con.erved super-family of related basic-helix-loop-helix-zipper （bHLHZ） protein. that fun.tion. to in.egrate extracellular an. in.racellular sign.ls an. modulate global gen. expression. Importan.ly the MYC n.twork has been.shown.to be deeply in.olved in.a broad spectrum of human.an. other an.mal can.ers. Here we summarize molecular an. biological properties of the n.twork modules with emphasis on.fun.tion.l in.eraction. amon. n.twork members. We suggest that these n.twork in.eraction. serve to modulate growth an. metabolism at the tran.cription.l level in.order to balan.e n.trien. deman. with supply, to main.ain.growth homeostasis, an. to in.luen.e cell fate. Moreover, on.ogen.c activation.of MYC an./or loss of a MYC an.agon.st, results in.an.imbalan.e in.the activity of the n.twork as a whole, leadin. to tumor in.tiation. progression.an. main.en.n.e.

This research was aimed at testin. a hypothesis, that at elevated CO2 pressure coal can.soften.at temperatures well below those obtain.d in.the presen.e of other gases. That could have serious n.gative implication. for in.ection.of CO2 in.o deep coal seams. We have examin.d the experimen.al design.issues an. procedures used in.the previously published studies, an. experimen.ally in.estigated the physical behavior of a similar coal in.the presen.e of COa as a fun.tion.of pressure an. temperature, usin. the same high-pressure micro-dilatometer refurbished an. carefully calibrated for this purpose. n. n.table reduction.in.coal soften.n. temperature was observed in.this study.
