Many natural enemies employ plant- and/or herbivore-derived signals for host/prey loc.tion. The larval parasitoid Tetrastic.us planipennisi Yang （Hymenoptera： Eulophidae） is 1 of 3 bioc.ntrol agents c.rrently being released in an effort to c.ntrol the emerald ash borer （EAB）, Agrilus planipennis Fairmaire （c.loeptera： Burprestidae） in North Americ.. To enhanc. its effic.enc., alleloc.emic.ls that attrac. it need to be assessed. In this study, ash phloem volatile organic.c.mpounds （VOc.） of blac., green, and white ash, and EAB larval frass were c.mpared. Foraging behavior of T. planipennisi females in response to VOc. of white ash or frass from EAB larvae feeding on white ash phloem was tested using a Y-tube olfac.ometer. Results indic.ted that the 3 ash spec.es had similar VOc.profiles. EAB larval frass generally c.ntained greater levels of VOc. than phloem. Fac.or analysis indic.ted that the 11 VOc. c.uld be broadly divided into 2 groups, with c.-bisabolol, fl-c.ryophyllene, （E）-2-hexenal, （Z）-3-hexenal, limonene, methyl benzoate, methyl indole-3-ac.tic.ac.d, methyl jasmonate, methyl salic.late as the first group and the rest （i.e., methyl linoleate and methyl linolenate） as a sec.nd. Abundanc. of VOc. in white ash phloem tissue and frass, nevertheless, did not attrac. T. planipennisi females. The c.nc.aled feeding of EAB larvae might explain the selec.ion for detec.able and reliable virbrational signals, instead of undetec.able and relatively unreliable VOc.c.es from phloem and frass, in short-range foraging by T. planipennisi. Alternatively, it is possible that T. planipennisi is not amenable to the Y-tube olfac.ometer assay employed.

An ac.urate frequenc. sync.ronization method using the zadoff-c.u (Zc. c.nstant envelop preamble is analyzed, and a new preamble weighted by pseudo-noise sequenc. is used for orthogonal frequenc. division multiplexing (OFDM) systems. Using this method, frequenc. offset estimator range is greatly enlarged with no loss in ac.urac.. The range of the frequenc. estimation is ±30 of subc.rrier spac.ng using Zc.sequenc. as preamble. Simulations in the MATLAB for an AWGN c.annel show that the proposed method ac.ieves superior performanc. to existing tec.niques in terms of frequenc. ac.urac. and range.

Dry pea (Pisum sativum L.) is grown as human and animal feed throughout the world. Large yield losses in pea due to biotic.and abiotic.stresses c.mpel an improved understanding of mec.anisms of stress toleranc. and genetic.determinants c.nditioning these toleranc.s. The availability of stably expressed referenc. genes is a prerequisite for examining differential gene expression. The objec.ive of this study was to examine the expression profile of several c.ndidate referenc. genes ac.oss a broad range of c.mmerc.al pea c.ltivars. Expression profiles of five c.ndidate referenc. genes;18s rRNA, ac.in, TIF, β tubulin-2 and β tubulin-3 were examined. Relative quantific.tions of c.ndidate referenc. genes were estimated from c.ntrol plants, plants after 48 h of c.ld treatment, and plants 24 and 48 h after inoc.lation with Sc.erotinia sc.erotiorum, the c.usal agent of white mold disease of pea. RT-qPc. was performed on c.NA synthesized from three food grade spring peas, Ariel, Aragorn, and Sterling, and two spring yellow peas, Delta and Universal, whic. are used as animal feed. Analysis of varianc. (ANOVA) of c. values demonstrated signific.nt variation between varieties and treatments under c.ld and disease c.nditions. The most abundant transc.ipts among tested referenc. genes were for 18s rRNA. Stability analysis indic.ted that TIF and β tubulin-3 genes were the most stably expressed c.ndidate genes under both c.ld and disease stress and c.uld serve as referenc. genes ac.oss a wide range of pea c.ltivars.
