Available in PDF, EPUB and Kindle. Book excerpt: The leafhopper genus Xyphon, included in the sharpshooters, is a widely distributed group of insects whose species are vectors for various plant diseases. Xyphon has historically contained up to 9 species. These species have been poorly delimited in the past and their identification has been difficult using published keys. The genus is revised here based on a new species level phylogenetic assessment that incorporates both morphological and molecular data. The genus Xyphon was erected to contain leafhoppers that possessed a reticulated forewing apex but lacked both a median sulcus on the crown and a carinate anterolateral crown-face margin both of which are present in the closely related genus Draeculacephala. Young (1977) revised most of the genera included in Xyphon's containing subfamily. He did not attempt a revision of Carneocephala (the genus that formerly contained most Xyphon species), but noted the need for a revision of its species. This revision of the genus Xyphon is based on the examination of approximately 8,000 specimens and includes a phylogenetic analysis of the genus that includes data from one gene (NDI) and 47 morphological characters. A generalized model of each preliminary taxonomic unit was used to test the monophyly of each species. These tests resulted in the synonomization of 4 former species: Xyphon gillettei to include X. balli; and X. reticulatum to include X. diductum, X. dyeri, and X. sagittiferum. Parsimony and Bayesian techniques were used to infer relationships among species. These analyses resulted in almost identical tree topologies. In all analyses Xyphon was monophyletic and Draeculacephala was its sister genus although clade support for the genus was generally low. The analyses found that X. flaviceps and X. fulgidum form a basal clade within Xyphon, above which X. gillettei and X. n. sp. 1 (new species 1) form a clade that is sister to a third clade containing X. triguttatum, X. nudum, and X. reticulatum.

Download or read book Attachment Devices of Insect Cuticle written by Stanislav S. N. Gorb and published by Springer Science & Business Media. This book was released on 2007-05-08 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1974 when I published my book, Biological Mechanism of Attachment, not many pages were required to report on the attachment devices of insect cuticles. As in most fields of research, our knowledge on this specific subject has simply exploded. Dr. Stanislav N. Gorb now describes the present day level of our knowledge, to which he has personally contributed so much, and a research team working on biological microtribology has gradually developed, also. With modern methods of measurement it is possible to enter the structure – function relationship much more deeply, even down to a molecular level, which was not possible two and a half decades ago. It is a well known fact that, in biology, the more sophisticated the measuring method, the greater the achievement of biological fundamental research, and its resulting evidence. Our knowledge remains at a certain level until new methods once more permit a forward leap. Biological knowledge develops in the form of a stepped curve rather than linear, as reflected in the studies carried out on the attachment devices of insect cuticles.
Download or read book Egg Parasitoids in Agroecosystems with Emphasis on Trichogramma written by Fernando L. Consoli and published by Springer Science & Business Media. This book was released on 2010-09-28 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: Egg Parasitoids in Agroecosystems with emphasis on Trichogramma was conceived to help in the promotion of biological control through egg parasitoids by providing both basic and applied information. The book has a series of chapters dedicated to the understanding of egg parasitoid taxonomy, development, nutrition and reproduction, host recognition and utilization, and their distribution and host associations. There are also several chapters focusing on the mass production and commercialization of egg parasitoids for biological control, addressing important issues such as parasitoid quality control, the risk assessment of egg parasitoids to non-target species, the use of egg parasitoids in integrated pest management programs and the impact of GMO on these natural enemies. Chapters provide an in depth analysis of the literature available, are richly illustrated, and propose future trends.
Download or read book Genomics of Plant Associated Bacteria written by Dennis C. Gross and published by Springer. This book was released on 2014-06-16 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes how genomics has revolutionized our scientific understanding of agriculturally important plant-associated bacteria. Each chapter focuses on the genomics of particular bacteria: the first described plant pathogen, Erwinia amylovora; phytoplasmas lacking cell walls; fastidious, phloem-restricted liberibacters; Pseudomonas syringae, which is a genetically tractable model system; Xanthomonas citri, which causes a disease that can devastate citrus crops and Pseudomonas fluorescens, which can protect plants from diseases. Topics considered in this volume include the importance of horizontal gene transfer in originating new bacterial strains and species and advances in transcriptomics that allow us to describe the complex regulatory networks critical to plant-microbe interactions. The availability of the Xanthomonas oryzae genome has led to new technologies in genome editing, which will revolutionize approaches to genetic engineering, even in eukaryotes. The contributions show how genomics has greatly accelerated progress toward understanding the biology of these bacteria and how that understanding can be translated into novel crop protection methods.

Triapitsyn and published by Univ of California Press. This book was released on 2008-11-18 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: An annotated catalog of type material of the genus Aphytis Howard (Hymenoptera: Aphelinidae) in the collection of the Entomology Research Museum, University of California, Riverside, California, USA (UCRC) provides information on 75 valid species. Curation of the UCRC Aphytis slide collection involved remounting 7,390 specimens from Hoyer's medium into Canada balsam (a single specimen per each slide). This included 7,292 specimens that were remounted, labeled, and databased and 98 specimens that were remounted and labeled but not databased (the types of the South African species received on loan from the South African National Collection of Insects, Plant Protection Research Institute, Pretoria, South Africa). Among these are 309 primary type specimens (i.e., holotypes, syntypes, lectotypes, and neotypes) belonging to 51 nominal species, 2,473 secondary type specimens (i.e., paratypes, allotypes, and paralectotypes) of various nominal species, and 4,608 nontype specimens of many species of Aphytis from more than 50 different countries. Numerous nomenclatural and other mistakes (such as improper or coded labeling) in the treatment of the type specimens of the Aphytis species are corrected; several primary types are returned to the appropriate depositories, and many remounted secondary types are donated to other major taxonomic collections of Aphelinidae. Lectotypes are designated for A. africanus Quednau, A. coheni DeBach, A. cylindratus Compere, A. equatorialis Rosen and DeBach, A. fisheri DeBach, A. holoxanthus DeBach, A. immaculatus Compere, A. lepidosaphes Compere, A. lingnanensis Compere, A. melinus DeBach and A. taylori Quednau.
