Book excerpt: Excerpt from The Genitalia of the Group Tortricidae of the Lepidoptera of the British Islands: An Account of the Morphology of the Male Clasping Organs and the Corresponding Organs of the Female After gathering together a fair collection of the British butterflies and larger moths, I found, in company with many other collectors of the British Lepidoptera, that, to a certain extent, Rome was conquered, and fresh fields for study must be opened up. Often it is not until this point is reached that the attention is turned to the "Micros," those marvellous little gems, of which many are so small that the keenest eye can hardly see to appreciate their beauty. Yet, with the perversity of human nature, it is not till the eye grows dim, that the average Lepidopterist begins his study of these fascinating objects. Possibly there is a reason for this otherwise unfortunate delay. The hand steadies, and becomes expert with practice, and the setting of a Micro, which would daunt a beginner, becomes easy to the experienced; hence the readiness in later life to attempt the more difficult. Thus after years spent in the preparation of the genitalia of the larger species, I decided to complete my collection of slides of the British Lepidoptera, and I now present the third volume of the series, which deals with the Tortricidae. I have in this volume been fortunate in securing the co-operation of the Rev. J. W. Metcalfe, who, in his great love of the Science, and at no little sacrifice, has made the drawings as fast as I could obtain the specimens, and prepare the slides, and I take this opportunity of offering to him my grateful thanks for this most valuable help. The result has been to speed up the work, and had it not been for the terrible war, this volume, dealing with the Tortrlcidae, might have been published in 1917.

Book excerpt: Excerpt from The Genitalia of the Group Tortricidæ of the Lepidoptera of the British Islands: An Account of the Morphology of the Male Clasping Organs and the Corresponding Organs of the Female In the previous volumes the genitalia were drawn to scale, a fact which had in some respects a certain advantage; but it had also the disadvantage of reducing the figures of the smaller species so greatly as to destroy, their value. After carefully weighing the pros and cons, we decided to keep the drawings fairly uniform in size, in order that the different and characteristic points, in even the smallest species, might be shown. I have found the Tortrix men so generous in helping with specimens, many in cases of difficulty sending their entire series to do as I liked with, that I have added the names of the donors to the species, so kindly provided by them, and I wish this to be a record of my grateful thanks. The ever difficult question of the Nomenclature has been considered, although from the point of view of my particular study, the question of names is really a matter of no great importance. The generic names have been worked out with the aid of Mr. O. H Fernald's The Genera of the Tortricidae and their types. Where we have been unable to find any existing generic name, we have left a blank space, and the same with regard to the type. So many genera have been created for foreign species, that, until these have been examined from a genitalic point of view, we have been averse to providing superfluous names for genera which may already exist. These blanks may be filled in as our knowledge increases. For the specific names I have relied mainly on the type collection in the Victoria Museum at Manchester, named by Mr. J. H. Durrant, and to him I am indebted for much help in this, and other matters. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book excerpt: Excerpt from The Genitalia of the Group Geometridæ of the Lepidoptera of the British Islands: An Account of the Morphology of the Male Clasping Organs and the Corresponding Organs of the Female As the penis forms an important, in many cases the most important, structure for purposes of differentiation, drawings of this organ have been added (on the right of each figure), but I would warn workers that it is extremely difficult in this case to get uniformity of position.

Download or read book Basic and Applied Aspects of Biopesticides written by K. Sahayaraj and published by Springer. This book was released on 2014-07-10 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: Currently, the major challenge of humanity is focused on population growth through agricultural production in order to meet the demand for food. The food crunch is mainly due to pest and disease. Traditional methods, synthetic insecticides and microbicides cause health hazards to human beings, domestic animals and also affect our immediate environments. Serious concerns were implemented by both developing and developed countries as Integrated Pest Management (IPM) and Bio-intensive Integrated Pest Management (BIPM) systems where biopesticides play an important role worldwide. The available books are limited to particular aspects of biopesticides. Hence, it is imperative to bring out a holistic documentation which will provide the reader information on all aspects of biopesticides. The book consists of five sections namely microbials, botanicals, natural enemies semio- chemicals and biotechnology and equipments, bioinformatics tools and IPM. In Section I, microbial deals with utilization of Bacillus in control of phytonematodes; biological control of pest and diseases with fluorescent pseudomonads, entomopathogenic fungus and entomopathogenic nematodes in pest management, microbial viral insecticides and microbial elicitors to induce immunity for plant disease control in chilli and tomato. Importance of plant essential oils, botanicals in endocrine disruption, relevance of botanicals and use of plant volatile on pest management has been discussed in Section II. Importance and role of reduviidae, weaver ants, ground beetles, Odonatas, spiders in biological control has been discussed in Section III. In addition, genetic improvement of biocontrol agents for sustainable pest management has also been highlighted. In Section IV, classical practices and pheromone, kairomonal enhancement to natural enemies and use of transgenic plants in insect control are highlighted. Equipment and their application methodologies for application of biopesticides; relevance of bioinformatics in biopesticides management; pest management of soybean, bio fouling and eco friendly antifoulants have been highlighted in Section V. Each chapter has objectives and conclusion along with recommendations.
