Temporal Genotypic Diversity of Schizaphis graminum (Rondani 1852) (Hemiptera: Aphididae) in a Black Oats (Avena strigosa) Field
The aim of this work was to analyze the clonal diversity variation in Schizaphis graminum during a complete phenological cycle of black oats (Avena strigosa). RAPD markers were used for detection of DNA polymorphisms of each clonal lineage, derived from a single clone collected weekly during a period of four months, in a crop field of black oats, Londrina, Paraná, Brazil. The monthly genotypic ...

Experiments were conducted in 2010 to determine the influence of plant density and seed position on the mother plant on seed physiological characteristics of cocklebur (Xanthium strumarium). Cocklebur burs were collected in fall of 2010 from Research Farm of University of Agricultural Sciences and Natural Resources of Gorgan, Iran. The experiment was established as factorial arrangement using a...
متن کاملBiology and biotype determination of greenbug, Schizaphis graminum (Hemiptera: Aphididae), on seashore paspalum turfgrass (Paspalum vaginatum).
Greenbug, Schizaphis graminum (Rondani) (Hemiptera: Aphididae), was first discovered damaging seashore paspalum (Paspalum vaginatum Swartz) turfgrass in November 2003 at Belle Glade, FL. Inquiries to several golf courses with seashore paspalum turf across southern Florida indicated infestation was wide spread by April 2004. Damage symptoms progress from water soaked lesions surrounding feeding ...
متن کاملاثر گیاه میزبان بر رشد و تولیدمثل شته سبز گندم Schizaphis graminum (Rondani) (Hem.: Aphididae)
گندم نان، Triticum aestivum L.، در بین گیاهان انگشت‌شماری که به عنوان منابع غذایی در سطح گسترده‌ای کشت می‌شوند، در ایران بالاترین اهمیت را داراست. در بین آفات گندم، شته سبز گندم Schizaphis graminum (Rondani) قادر است در جمعیت زیاد خسارت جبران‌ناپذیری به گندم وارد کند. از آنجا که شایستگی شته روی رقم‌های مختلف، متفاوت می‌باشد، در این پژوهش اثر پنج رقم از ارقام متداول گندم کرج روی پارامترهای زیست...
متن کاملAmplification and methylation of an esterase gene associated with insecticide-resistance in greenbugs, Schizaphis graminum (Rondani) (Homoptera: Aphididae).
The greenbug aphid, Schizaphis graminum (Rondani) has developed resistance to organophosphorus insecticides by the over-production of esterases that have been classified as Type I and Type II. The first twenty N-terminal amino acids of the Type I esterase were determined and used to design an oligonucleotide, which in conjunction with an active site primer derived from conserved sequences of ot...
