Testing the fecundity advantage hypothesis with Sitobion avenae, Rhopalosiphum padi, and Schizaphis graminum (Hemiptera: Aphididae) feeding on ten wheat accessions
The fecundity advantage hypothesis suggests that females with a large body size produce more offspring than smaller females. We tested this hypothesis by exploring the correlations between life-history traits of three aphid species feeding on ten wheat accessions at three levels of analysis with respect to the host plant: overall, inter-accession, and intra-accession. We found that fecundity wa...
متن کاملeffect of host plant on development and reproduction of schizaphis graminum (rondani) (hem.: aphididae)
common wheat, triticum aestivum l. is of the greatest importance among the few crop plants that are grown extensively and for food in iran. among the reported wheat's pests, greenbug schizaphis graminum (rondani) causes severe damage to the crop. because of the adaptation of the aphid to different wheat varieties being varied, this study was designed to focus on the effect of some common w...
متن کاملنمونهبرداری دنباله‌دار شته‌های Rhopalosiphum maidis و Schizaphis graminum (Hem.: Aphididae) در مزارع گندم منطقه باجگاه، استان فارس
طی نمونه‌برداری‌هایی که در سال زراعی 90-1389 از شته‌های Rhopalosiphum maidis F. و Schizaphis graminum R. در مزارع گندم منطقه باجگاه، استان فارس، انجام شد، پراکنش فضایی و مدل‌های نمونه‌گیری دنباله‌ای با دقت ثابت مورد مطالعه قرار گرفت. برای این منظور دو مزرعه دو هکتاری انتخاب و به‌صورت هفتگی نمونه‌برداری انجام شد. در هر تاریخ تعداد 200 بوته گندم به‌طور تصادفی انتخاب و تعداد شته‌های آن‌ها شمارش ش...
متن کاملBiological aspects of Eriopis connexa (Germar) (Coleoptera: Coccinellidae) fed on different insect pests of maize (Zea mays L.) and sorghum [Sorghum bicolor L. (Moench.)].
Eriopis connexa (Germar) (Coleoptera: Coccinellidae) occurs in several countries of South America and its mass rearing is important for biological control programmes. This work evaluated biological aspects of E. connexa larva fed on eggs of Anagasta kuehniella (Zeller) (Lepidoptera: Pyralidae) and Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) frozen for one day, fresh eggs of Dia...
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...
