نمونه‌برداری دنباله‌ای شته‌ی Metopolophium dirhodum (Hemiptera: Aphididae) در مزارع گندم
این پژوهش به منظور تهیه‌ی الگوی نمونه‌برداری دنباله‌ای شته‌ی گندم-گل سرخ،Metopolophium dirhodum (Walker)، در مزارع گندم آبی منطقه‌ی جلیل‌آباد ورامین انجام شد. برای این منظور نمونه‌برداری‌های هفتگی از جمعیت شته در طول دو فصل زراعی 1379 و 1380 انجام شد. در هر نمونه‌برداری، تعداد 50 ساقه‌ی گندم به طور تصادفی انتخاب و تعداد شته‌های موجود شمارش شد. با داده‌های به‌دست آمده، الگوی توزیع فضایی جمعیت ش...
متن کاملHeterogeneity in the Second Internal Transcribed Spacer (ITS2) of rDNA in the Genetically Distinct Metopolophium dirhodum Isofemale Lineages (Hemiptera: Aphididae)
The aim of this study was to investigate the level of evolutionary divergence among five isofemale lineages of Metopolophium dirhodum Walker (Hemiptera: Aphididae) using sequences of the Internal Transcribed Spacer (ITS) of ribosomal DNA (rDNA). These isofemalelineages were derived from parthenogenetic females, previously genetically characterized by having strong association of RAPD (Random Am...
متن کاملWheat Nitrogen Fertilisation Effects on the Performance of the Cereal Aphid Metopolophium dirhodum
The effects of five rates of nitrogen fertiliser applications on the performance of the cereal aphid Metopolophium dirhodum on winter wheat, within the range of rates recommended for UK crops, were investigated over two seasons in field-grown crops and also on plants grown in the glasshouse. Longevity was unaffected by the level of fertilisation, but aphid intrinsic rate of increase and fecundi...
متن کاملAncestral QTL Alleles from Wild Emmer Wheat Improve Drought Resistance and Productivity in Modern Wheat Cultivars
Wild emmer wheat (Triticum turgidum ssp. dicoccoides) is considered a promising source for improving stress resistances in domesticated wheat. Here we explored the potential of selected quantitative trait loci (QTLs) from wild emmer wheat, introgressed via marker-assisted selection, to enhance drought resistance in elite durum (T. turgidum ssp. durum) and bread (T. aestivum) wheat cultivars. Th...
متن کاملComparison of chlorophyll and carotenoid concentrations among Russian wheat aphid (Homoptera: Aphididae)-infested wheat isolines.
Russian wheat aphid, Diuraphis noxia (Mordvilko), feeding injury on 'Betta' wheat isolines with the Dn1 and Dn2 genes was compared by assessing chlorophyll and carotenoid concentrations, and aphid fecundity. The resistant Betta isolines (i.e., Betta-Dn1 and Betta-Dn2) supported similar numbers of aphids, but had significantly fewer than the susceptible Betta wheat, indicating these lines are re...
