Effect of greenbugs (Homoptera: Aphididae) on yield loss of winter wheat.
The effect of greenbug, Schizaphis graminum (Rondani), feeding on the yield of four winter wheat cultivars commonly grown in Oklahoma was studied. Cultivars tested were 'Karl', a recent derivative 'Karl-92', and '2163', all greenbug-susceptible cultivars; and 'TAM-110', a cultivar with resistance to biotype E greenbugs. The objectives were to determine the effect of different greenbug densities...
متن کاملSeasonal Abundance and Diversity of Aphids (Homoptera: Aphididae) in a Pepper Production Region in Jamaica
Seasonal dispersal and diversity of aphid species were monitored on pepper farms in St. Catherine, Jamaica throughout 1998 and 1999 to identify the most likely vectors of tobacco etch virus (TEV) in pepper Þelds. Flight activitywasmonitoredweekly on Þve farms usingwater pan traps. More than 30 aphid species were identiÞed, 12 of which are new records for Jamaica. Ninety-two percent of the aphid...

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 کاملReflectance characteristics of Russian wheat aphid (Hemiptera: Aphididae) stress and abundance in winter wheat
The Russian wheat aphid (Diuraphis noxia (Mordvilko)) infests wheat (Triticum aestivum L.), barley (Hordeum vulgare L.), and other small grains and grasses. Russian wheat aphid infestations are unpredictable in time and space. In favorable conditions, Russian wheat aphid feeding can result in heavy damage to wheat and barley in a short period of time. A repetitive monitoring strategy that allow...
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...
