Book excerpt: Russian wheat aphid (RWA), Diuraphis noxia (Mordvilko), is a widely distributed species in western north America, and a major economic pest of wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.). The objectives of this study were to : 1) determine the inheritance of seedling and adult plant resistances in a wheat line PI 294994 ; 2) establish whether greenhouse and field resistances were related ; 3) determine the effect of RWA infestation on the dry matter, grain yield, and harvest index in the crosses Moro/PI 294994 and Hyak/PI 294994 ; 4) determine whether there was a difference in the three traits between different genotypes due to RWA infestation ; and, 5) assess the degree of protection genetic resistance provided in the two crosses. The club wheat cultivars 'Moro' and 4Hyak' were crossed with PI 294994. Progenies from these two crosses were artificially infested with RWA in the field and the crosses were compared for their dry matter, grain yield, and harvest index. Plant reactions of F2 seedlings, F2 adult plants, and F3 seedlings indicated that both seedling and adult plant resistances are controlled by two genes with dominant and recessive mode of inheritance and that plant reactions in the field were the same as those in the greenhouse. Comparison of mean values of dry matter, grain yield, and harvest index showed that the three traits were affected by RWA infestation and genotype in both crosses. Resistant genotypes and noninfested population were comparable with respect to the three traits in Moro/PI 294994 but they were not in Hyak/PI 294994.

Download or read book Entomology written by Cedric Gillott and published by Springer Science & Business Media. This book was released on 2005-12-27 with total page 835 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gillott’s thorough yet clear writing style continues to keep Entomology near the top of the class as a text for senior undergraduates, and for graduate students and professionals seeking an introduction to specific entomological topics. The author’s long-held belief that an introductory entomology course should present a balanced treatment of the subject is reflected in the continued arrangement of the book in four sections: Evolution and Diversity, Anatomy and Physiology, Reproduction and Development, and Ecology. For the third edition, all chapters have been updated. This includes not only the addition of new information and concepts but also the reduction or exclusion of material no longer considered "mainstream", so as to keep the book at a reasonable size. Based on exciting discoveries made during the previous decade, the topics of insect evolutionary relationships, semiochemicals, gas exchange, immune responses (including those of parasites and parasitoids), flight, and the management of pests have received particular attention in the preparation of the third edition. Overall, more than 30 new or significantly revised figures have been incorporated.
