Book excerpt: ABSTRACT: Lettuce (Lactuca sativa L.) quality and yield can be reduced by feeding of several insect pests. Host plant resistance to these insects is an environmentally sound adjunct to conventional chemical control. In this study I compared the survival, development and feeding behavior of cabbage looper, Trichoplusia ni (Hübner) and beet armyworm Spodoptera exigua (Hübner) on two romaine lettuce cultivars, resistant 'Valmaine' and susceptible 'Tall Guzmaine'. The survival and development of both species was significantly less on resistant Valmaine than on susceptible Tall Guzmaine. The two insect species showed different feeding preference for leaves of different age groups on Valmaine and Tall Guzmaine. Latex from Valmaine strongly inhibited feeding of banded cucumber beetle, Diabrotica balteata LeConte compared to Tall Guzmaine when applied to the surface of artificial diet in both choice and no-choice tests. In a choice test involving diet disks treated with Valmaine latex from young leaves versus mature leaves, the beetles consumed significantly less diet treated with latex from young than mature leaves. No significance difference in feeding was found between diet disks treated with latex from young and mature Tall Guzmaine leaves in choice tests. Three solvents of differing polarity (water, methanol and methylene chloride) were tested to extract deterrent compounds from latex; Valmaine latex extracted with water:methanol (20:80) strongly.

Book Synopsis Induced Responses to Herbivory by : Richard Karban
Download or read book Induced Responses to Herbivory written by Richard Karban and published by University of Chicago Press. This book was released on 2007-12-01 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants face a daunting array of creatures that eat them, bore into them, and otherwise use virtually every plant part for food, shelter, or both. But although plants cannot flee from their attackers, they are far from defenseless. In addition to adaptations like thorns, which may be produced in response to attack, plants actively alter their chemistry and physiology in response to damage. For instance, young potato plant leaves being eaten by potato beetles respond by producing chemicals that inhibit beetle digestive enzymes. Over the past fifteen years, research on these induced responses to herbivory has flourished, and here Richard Karban and Ian T. Baldwin present the first comprehensive evaluation and synthesis of this rapidly developing field. They provide state-of-the-discipline reviews and highlight areas where new research will be most productive. Their comprehensive overview will be welcomed by a wide variety of theoretical and applied researchers in ecology, evolutionary biology, plant biology, entomology, and agriculture.

Book Synopsis Tropical Agroforestry by : Alain Atangana
Download or read book Tropical Agroforestry written by Alain Atangana and published by Springer Science & Business Media. This book was released on 2013-10-29 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agroforestry is recognized as a sustainable land-use management in the tropics, as it provides environmental-friendly ecosystems; it also provides people with their every day need for food and cash. Since the recognition of agroforestry as a science, curricula have been developed for agroforestry programs for undergraduate and graduate trainings in Universities. Therefore, there is an urgent need to develop and make available educational material. This textbook strives to provide up-to-date information on tropical agroforestry to serve as educational material in the tropical context. The authoritative textbook of Nair (1993) on agroforestry was published 18 years ago, and before the advent of tree domestication, an important agroforestry practice today. In addition, many other research activities, such as carbon sequestration and integrated pest management, have been included in the agroforestry agenda. This textbook is intended for agroforestry students, teachers, and practitioners.
Book Synopsis Integrated Pest and Disease Management in Greenhouse Crops by : Ramon Albajes
Download or read book Integrated Pest and Disease Management in Greenhouse Crops written by Ramon Albajes and published by Springer Science & Business Media. This book was released on 2006-04-11 with total page 566 pages. Available in PDF, EPUB and Kindle. Book excerpt: The International Centre for Advanced Mediterranean Agronomic Studies (CIHEAM), established in 1962, is an intergovernmental organization of 13 countries: Albania, Algeria, Egypt, France, Greece, Italy, Lebanon, Malta, Morocco, Portugal, Spain, Tunisia and Turkey. Four institutes (Bari, Italy; Chania, Greece; Montpellier, France; and Zaragoza, Spain) provide postgraduate education at the Master of Science level. CIHEAM promotes research networks on Mediterranean agricultural priorities, supports the organization of specialized education in member countries, holds seminars and workshops bringing together technologists and scientists involved in Mediterranean agriculture and regularly produces diverse publications including the series Options Méditerranéennes. Through these activities, CIHEAM promotes North/South dialogue and international co-operation for agricultural development in the Mediterranean region. Over the past decade, the Mediterranean Agronomic Institute of Zaragoza has developed a number of training and research-supporting activities in the field of agroecology and sustainability of agricultural production systems. Some of these activities have been concerned with the rational use of pesticides and more particularly with the implementation of integrated control systems in order to gain in efficacy and decrease both the environmental impact and the negative repercussions for the commercialization of agricultural products.

Book Synopsis Small-scale Aquaponic Food Production by : Christopher Somerville
Download or read book Small-scale Aquaponic Food Production written by Christopher Somerville and published by Fao. This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This technical paper begins by introducing the concept of aquaponics, including a brief history of its development and its place within the larger category of soil-less culture and modern agriculture. It discusses the main theoretical concepts of aquaponics, including the nitrogen cycle and the nitrification process, the role of bacteria, and the concept of balancing an aquaponic unit. It then moves on to cover important considerations of water quality parameters, water testing, and water sourcing for aquaponics, as well as methods and theories of unit design, including the three main methods of aquaponic systems: media beds, nutrient film technique, and deep water culture. The publication discusses in detail the three groups of living organisms (bacteria, plants and fish) that make up the aquaponic ecosystem. It also presents management strategies and troubleshooting practices, as well as related topics, specifically highlighting local and sustainable sources of aquaponic inputs. The publication also includes nine appendixes that present other key topics: ideal conditions for common plants grown in aquaponics; chemical and biological controls of common pests and diseases including a compatible planting guide; common fish diseases and related symptoms, causes and remedies; tools to calculate the ammonia produced and biofiltration media required for a certain fish stocking density and amount of fish feed added; production of homemade fish feed; guidelines and considerations for establishing aquaponic units; a cost-benefit analysis of a small-scale, media bed aquaponic unit; a comprehensive guide to building small-scale versions of each of the three aquaponic methods; and a brief summary of this publication designed as a supplemental handout for outreach, extension and education.
