Biological Control In Ipm Systems In Africa

by P. Neuenschwander, Biological Control In Ipm Systems In Africa Books available in PDF, EPUB, Mobi Format. Download Biological Control In Ipm Systems In Africa books, Annotation. Biological control has made a major contribution to integrated pest management (IPM) in Africa, but its documentation has been scattered and often under-reported. This book provides a review of the most important studies, including not only successes, but also on-going challenges. The focus is on arthropod pests and weeds, but diseases are also covered where significant. In 24 chapters, case studies and promising research results are presented that cover biocontrol by naturally occurring agents, by exotic agents or by seasonal manipulation. This book provides a valuable resource for scientists worldwide. It is particularly useful for pest control professionals working in Africa.

Tropical Biology And Conservation Management Volume Iii

by Kleber Del Claro, Tropical Biology And Conservation Management Volume Iii Books available in PDF, EPUB, Mobi Format. Download Tropical Biology And Conservation Management Volume Iii books, This Encyclopedia of Tropical Biology and Conservation Management is a component of the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. Tropical environments cover the most part of still preserved natural areas of the Earth. The greatest biodiversity, as in terms of animals and plants, as microorganisms, is placed in these hot and rainy ecosystems spread up and below the Equator line. Additionally, the most part of food products, with vegetal or animal origin, that sustain nowadays human beings is direct or undirected dependent of tropical productivity. Biodiversity should be looked at and evaluated not only in terms of numbers of species, but also in terms of the diversity of interactions among distinct organisms that it maintains. In this sense, the complexity of web structure in tropical systems is a promise of future to nature preservation on Earth. In the chemicals of tropical plant and animals, could be the cure to infinite number of diseases, new food sources, and who knows what more. Despite these facts tropical areas have been exploited in an irresponsible way for more than 500 years due the lack of an ecological conscience of men. Exactly in the same way we did with temperate areas and also tropical areas in the north of Equator line. Nowadays, is estimated that due human exploitation, nation conflicts and social problems, less than 8% of tropical nature inside continental areas is still now untouchable. The extension of damage in the tropical areas of oceans is unknown. Thus so, all knowledge we could accumulate about tropical systems will help us, as in the preservations of these important and threatened ecosystems as in a future recuperation, when it was possible. Only knowing the past and developing culture, mainly that directed to peace, to a better relationship among nations and responsible use and preservation of natural resources, human beings will have a long future on Earth. These volumes, Tropical Biology and Natural Resources was divided in sessions to provide the reader the better comprehension possible of issue and also to enable future complementation and improvements in the encyclopedia. Like we work with life, we intended to transform this encyclopedia also in a “life” volume, in what new information could be added in any time. As president of the encyclopedia and main editor I opened the theme with an article titled: “Tropical Biology and Natural resources: Historical Pathways and Perspectives”, providing the reader an initial view of the origins of human knowledge about the tropical life, and what we hope to the future. In the sequence we have more than 100 chapters distributed in tem sessions: Tropical Ecology (TE); Tropical Botany (TB); Tropical Zoology (TZ); Savannah Ecosystems (SE); Desert Ecosystems (DE); Tropical Agriculture (TA); Natural History of Tropical Plants (NH); Human Impact on Tropical Ecosystems (HI); Tropical Phytopathology and Entomology (TPE); Case Studies (CS). This 11-volume set contains several chapters, each of size 5000-30000 words, with perspectives, applications and extensive illustrations. It is the only publication of its kind carrying state-of-the-art knowledge in the fields of Tropical Biology and Conservation Management and is aimed, by virtue of the several applications, at the following five major target audiences: University and College Students, Educators, Professional Practitioners, Research Personnel and Policy Analysts, Managers, and Decision Makers and NGOs.

by Rangaswamy Muniappan, Integrated Pest Management Of Tropical Vegetable Crops Books available in PDF, EPUB, Mobi Format. Download Integrated Pest Management Of Tropical Vegetable Crops books, It is an edited book with chapters written by multi-disciplinary specialists in their specific subject areas. It covers development of IPM components and packaging them for individual vegetable crops specifically targeted to tropical countries. Scientific background for IPM components or tactics will be included. There will be case studies of IPM packages developed and implemented in different countries. The concept of IPM has been in existence for the past six decades; however, a practical holistic program has not been developed and implemented for vegetable crops, in the developing countries. Currently the IPM adoption rate in the tropics is minimal and there is a need for implementation of IPM technologies that are environmentally safe, economical, and socially acceptable. We believe that adoption and implementation of IPM provided in this book will lead to significant reduction in crop losses and mitigate adverse impacts of pesticide use in the tropics. This book is an outcome 20 years of research, development and implementation of the IPM CRSP, a project supported by USAID and administered by Virginia Tech in several developing countries along the tropical belt in Africa, Asia, Latin America and the Caribbean. ​

Presence And Frequency Of Occurence Of Plant Parasitic Nematodes On Coffee Coffea Arabica L Rubiaceae In Ethiopia And The Importance Of Endophytic Microorganisms For Biocontrol

by Tesfamariam Mekete, Presence And Frequency Of Occurence Of Plant Parasitic Nematodes On Coffee Coffea Arabica L Rubiaceae In Ethiopia And The Importance Of Endophytic Microorganisms For Biocontrol Books available in PDF, EPUB, Mobi Format. Download Presence And Frequency Of Occurence Of Plant Parasitic Nematodes On Coffee Coffea Arabica L Rubiaceae In Ethiopia And The Importance Of Endophytic Microorganisms For Biocontrol books, A survey was conducted to determine the occurrence and distribution of plant-parasitic nematodes and associated endophytic fungi and bacterial antagonists on coffee in Ethiopia. Soil and root samples were collected from 15 coffee growing agroecologies during the wet season in August 2004 and dry season in April 2006. The dominant plant-parasitic nematode genera found were Helicotylenchus, Scutellonema, Rotylenchus, Xiphinema, Heterodera, Tylenchorhynchus and Quinisulcius. Helicotylenchus predominated throughout the area (65-74%), followed by Xiphinema (29-40%). Nematode densities were generally higher in the wet season than in the dry season, however, relative abundance of nematode taxa was in the same order. For the major plant-parasitic nematode genera, specimens were identified to the following species: Helicotylenchus dihystera, H. multicinctus, H. californicus, H. gerti, Xiphinema insigne, X. basilgoodeyi, Scutellonema paralabiatum, Rotylenchus unisexus, Tylenchorhynchus agri and Quinisulcius capitatus. Nematodes considered to be of economic importance and involved in coffee decline were not detected in this survey. A total of 128 fungi growing endophytically were obtained from surface sterilized coffee roots. The most frequently detected genera were Fusarium and Trichoderma. Nematicidal effects of culture filtrates of these isolates on M. incognita juveniles were observed after 24 h of incubation. Juvenile inactivity ranged from 28% to 81% in which Trichoderma strain ET2 showed the highest level of inactivity up to 81%. Same isolates were tested for their pathogenicity towards M. incognita eggs. Isolates EF1, EF3, EF5, EF6, EF8, EF10, EF11, EU2 and EU4 showed the highest ability to infect eggs with values up to 89%. The percentage of egg pathogenicity was highest for Fusarium spp. Results of replicated greenhouse experiments demonstrated that isolates of Fusarium and Trichoderma reduced the number root-knot nematode egg masses up to 50%. Of all the tested isolates, the F. oxysporum isolate EF11 significantly reduced the number of egg masses in all sets of experiments. Reduction in nematode penetration ranging up to 30% was also recorded in the present study for isolates EF11 and EF10. Endophytic bacteria were isolated and identified by Fatty Acid Methyl Ester-Gas Chromatography (FAME-GC). A total of 201 and 114 endophytic bacteria were isolated and identified during the wet and dry seasons, respectively. The most abundant genera found were Pseudomonas, Bacillus, Agrobacterium, Stenotrophomonas and Enterobacter. Higher population size densities ranging from 5.2 x 103 to 2.07 x 106 cfu g- 1 fresh root were observed during the wet season. Culture filtrates of the bacterial isolates showed nematicidal effects ranged between 38% and 98%. The active strains were: Agrobacterium radiobacter, Bacillus pumillus, B. brevis, B. megaterium, B. mycoides, B. licheniformis, Chryseobacterium balustinum, Cedecea davisae, Cytophaga johnsonae, Lactobacillus paracasei, Micrococcus luteus, M. halobius, Pseudomonas syringae and Stenotrophomonas maltophilia. Bacillus pumillus and B. mycoides were the most effective strains in reducing the number of egg masses and galls up to 39 and 33%, respectively.

Download Pollination Biology Vol 1 books, The book covers interplay between pest management strategies and safety of pollinators. Detailed information is provided on pests and pollinators of temperate, subtropical and tropical fruit crops. Most of the fruit crops are highly cross pollinated and depend upon insects or benefit from insect pollination for fruit set. Insect pests on the other hand cause major economic damage on fruit crops in tropics, subtropics and temperate. Evidently, pest management in fruit crops on one hand and providing safety to the pollinators on the other is a challenging task in the context of increasing horticultural productivity without upsetting the ecological balance. This book aims to integrate and develop pest control strategies in a way to minimize their impact on beneficial insect species such as natural enemies and pollinators to enhance fruit production and quality.
