This book was released on 2019-05-14 with total page 515 pages. Available in PDF, EPUB and Kindle. Book excerpt: A groundbreaking guide to flower flies in North America This is the first comprehensive field guide to the flower flies (also known as hover flies) of northeastern North America. Flower flies are, along with bees, our most important pollinators. Found in a varied range of habitats, from backyard gardens to aquatic ecosystems, these flies are often overlooked because many of their species mimic bees or wasps. Despite this, many species are distinctive and even subtly differentiated species can be accurately identified. This handy and informative guide teaches you how. With more than 3,000 color photographs and 400 maps, this guide covers all 416 species of flower flies that occur north of Tennessee and east of the Dakotas, including the high Arctic and Greenland. Each species account provides information on size, identification, abundance, and flight time, along with notes on behavior, classification, hybridization, habitats, larvae, and more. Summarizing the current scientific understanding of our flower fly fauna, this is an indispensable resource for anyone, amateur naturalist or scientist, interested in discovering the beauty of these insects. · 3000+ color photos (field and museum shots) · Multiple images per species, with arrows highlighting key field marks · Grayscale images showing the actual size of the insect · Range maps for each species · Information on size, identification features, abundance, flight times, and more

G. D. May 1976 Part III THEORDERSOFINSECTS THE CLASSIFICATION AND PHYLOGENY OF INSECTS The classification of insects has passed through many changes and with the growth of detailed knowledge an increasing number of orders has come to be recognized. Handlirsch (1908) and Wilson and Doner (1937) have reviewed the earlier attempts at classification, among which the schemes of Brauer (1885), Sharp (1899) and Borner (1904) did much to define the more distinctive recent orders. In 1908 Handlirsch published a more revolutionary system, incorporating recent and fossil forms, which gave the Collembola, Thysanura and Diplura the status of three independent Arthropodan classes and considered as separate orders such groups as the Sialoidea, Raphidioidea, Heteroptera and Homoptera. He also split up the old order Orthoptera, gave its components ordinal rank and regrouped them with some of the other orders into a subclass Orthopteroidea and another subclass Blattaeformia.

Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive study of the biology, taxonomy, and ecology of each of the soil biotic groups. The first chapter presents an ecological approach to soil studies. The remaining 42 chapters provide specific information on each of the taxonomic groupings. Contains illustrated identification keys to each group. Some keys go by functional morphological delineations; others lead the reader to classical identification at family, genus, or species levels. Some incorporate descriptions of new genera and species. Especially useful for the study of mesic, xeric, and hydric terrestrial sites. Includes an extensive bibliography.

Download or read book Crop Pest Control and Pollination volume II 2nd edition written by Fang Ouyang and published by Frontiers Media SA. This book was released on 2023-12-01 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: The production of food crops helps us meet the basic need of human nutrition. The world's population now exceeds 7 billion people and continues to grow. Alongside this growth, the human demand for food also increases rapidly. Crop production is becoming increasingly intensive and large-scale and, as a result, simplified landscape-systems form. Crop production in simplified agricultural landscapes often face or suffer from various threats, such as pest damage (caused by diseases, insect pests, weeds and rodents) or a shortage of pollinators. These pests can cause serious damage to seeds, germination, growth, breeding and maturity during crop production and food storage, however, effective pest management can help to reduce crop loss. Most crops, in particular fruit trees and vegetables, require insect pollination to ensure high yields and high quality. Research into ecosystem services and their potential impact on pest control and pollination in agricultural landscapes is of great significance to sustainable crop production. Simplified and intensive agricultural landscapes can support crop production, but often have reduced biodiversity as monoculture cropping systems have limited surrounding natural habitat. This lack of natural surrounding habitat leads to the loss of ecosystem service benefits such as natural pest control and pollination. Over the past few decades, pest control has largely relied on chemical pesticides which can control pests and reduce crop losses in the short term. However, chemical pesticides cause a number of problems in the long run, for example, pest resistance to pesticides, and residues of pesticides in soil, water, and agricultural products. Excessive, improper, and long-term use of pesticides during crop production ultimately harms human health and biodiversity, especially beneficial microbes, natural enemies and pollinators. To achieve and ensure food security, food safety and ecological security, new theories, methods, practice, and application patterns need to be developed for environmentally friendly pest control and maintenance of pollination in agricultural landscapes for sustainable food production. The aim of this Research Topic is to promote the sustainable management of crop production and ecological environment protection through the discussion of crop pest control and pollination, and the publication of original research articles and reviews of research and theory. We welcome high-quality and original contributions that present original papers on basic and applied research covering aspects of natural pest control and pollination. Coverage for this Research Topic includes the biology and ecology of pollinators (including wild and managed), organisms (including parasitoids, invertebrate and vertebrate predators of insect pest and plants, mites, plant and insect pathogens, nematodes, and weeds) used for biological control, and aspects of use including biological control agents for integrated pest management on food crops, fruits and vegetables in agricultural landscapes. Natural pest control is an environmentally beneficial and effective means of reducing or mitigating pests and pest damage through the use of natural enemies. Ecological, ethological, molecular, and biotechnological approaches to the understanding of natural pest control and pollination in agricultural landscapes are welcome. Such as, by maintaining and increasing crop genetic diversity (not including genetically engineered crops), crop diversity, species diversity (not including genetically altered insects) and landscape diversity in cropping systems.
