Book Climate Change Effects on the Pest Status and Distribution of the Bean Leaf Beetle Cerotoma Trifurcata

Download or read book Climate Change Effects on the Pest Status and Distribution of the Bean Leaf Beetle Cerotoma Trifurcata written by Emily Berzitis and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The bean leaf beetle, Cerotoma trifurcata (Förster) (Coleoptera: Chrysomelidae), has recently become a major pest of soybean (Glycine max (L.) Merrill) in North America. With the possibility of further economic losses, an understanding of the potential indirect and direct effects of climate change on the severity of this pest is required. The plant-mediated effects of elevated CO2 on bean leaf beetle fecundity were examined. While non-nitrogen-fixing plants generally show decreases in leaf carbon to nitrogen ratio under elevated CO2, which can negatively impact insect herbivores, there was no change in the carbon to nitrogen ratio of soybean leaves, a nitrogen-fixer, in this study. The lack of change in leaf carbon to nitrogen ratio under elevated CO2 may explain the absence of a treatment effect on bean leaf beetle fecundity in one year of the experiment. However, in the second year, there was an increase in bean leaf beetle fecundity under elevated CO2. Using a multi-year field experiment, I examined the potential direct effects of climate change, namely the impacts of warmer winters on bean leaf beetle overwintering survival and spring emergence. Under increased temperatures, bean leaf beetles emerged 10 to 20 days earlier in the spring which could allow for an additional generation during the growing season. Higher temperatures also led to decreased survival. I developed a bioclimatic envelope model for the bean leaf beetle to examine the direct effects of climate change on a broader scale. I combined this model with the soybean climate envelope to predict the future potential distribution of the bean leaf beetle based both on climate and host plant availability. Since soybean generally has narrower tolerances than the bean leaf beetle, incorporation of host plant availability had a substantial impact on predictions of bean leaf beetle distribution. The inclusion of climate projections from multiple general circulation models (GCMs) and scenarios was a source of variability in our predictions, with only two of the three GCMs predicting further expansion of the bean leaf beetle into Canada.

Book Quantification of Climate Variability Adaptation and Mitigation for Agricultural Sustainability

Download or read book Quantification of Climate Variability Adaptation and Mitigation for Agricultural Sustainability written by Mukhtar Ahmed and published by Springer. This book was released on 2016-09-06 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a comprehensive volume dealing with climate change impacts on agriculture, and which can help guide the redesign of agricultural management and cropping systems. It includes mitigation techniques such as use of bioenergy crops, fertilizer and manure management, conservation tillage, crop rotations, cover crops and cropping intensity, irrigation, erosion control, management of drained wetlands, lime amendments, residue management, biochar and biotechnology. It also includes Management of GHG emissions Crop models as decision support tools QTL analysis Crop water productivity Impacts of drought on cereal crops Silvopastoral systems Changing climate impact on wheat-based cropping systems of South Asia Phosphorous dynamics under changing climate Role of bioinformatics The focus of the book is climate change mitigation to enhance sustainability in agriculture. We present various kinds of mitigation options, ways to minimize GHG emissions and better use of the latest techniques in conservation and environmental-sustainability.

Book Advances in Crop Environment Interaction

Download or read book Advances in Crop Environment Interaction written by Santanu Kumar Bal and published by Springer. This book was released on 2018-11-02 with total page 437 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agriculture is currently facing multi-faceted threats in the form of unpredictable weather variability, frequent droughts and scarcity of irrigation water, together with the degradation of soil resources and declining environmental health. These stresses result in the modification of plant physiology to impart greater resilience to changing abiotic and biotic environments, but only at the cost of declining plant productivity. In light of these facts, assessing the status of natural resource bases, and understanding the mechanisms of soil-plant-environment interactions so as to devise adaptation and mitigation approaches, represent great and imminent challenges for all of us. In this context, it is essential to understand the potential applications of modern tools, existing coping mechanisms and their integration, as this will allow us to develop suitable advanced mitigation strategies. From a broader perspective, the book deals with crop-environment interaction in the context of changing climatic conditions. To do so, it addresses four major aspects: Understanding the mechanism of carbon dynamics in the soil-plant-environment continuum; greenhouse gas fluxes in agricultural systems; and soil properties influenced by climate change and carbon sequestration processes. Mitigation and management of the photo-thermal environment to improve crop productivity; soil health under variable climate; reducing agro-ecosystem evapotranspiration losses through biophysical controls; and heat stress in field crops and its management. Studying the impact of climate change on biotic environments; insect-pest interactions; manifestations of disease; and adaptation strategies for island agro-ecosystems. Innovative approaches to assess stress impacts in crops, such as crop modeling, remote sensing, spectral stress indices etc. The book presents a collection of contributions from authoritative experts in their respective fields. Offering young researchers new perspectives and future research directions, it represents a valuable guide for graduate students and academics alike.

Book Winter Survival and Population Dynamics of Bean Leaf Beetle Coleoptera Chrysomelidae

Download or read book Winter Survival and Population Dynamics of Bean Leaf Beetle Coleoptera Chrysomelidae written by Wai-Ki Frankie Lam and published by . This book was released on 1999 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecological study of the population dynamics of bean leaf beetle adults, Cerotoma trifurcata (Förster) (Coleoptera: Chrysomelidae), with special reference to the overwintering populations, was conducted in central Iowa. Ecological habits, spatial distribution, cold tolerance, and winter survival of overwintering beetle adults were studied for 3-yr. (1996 through 1999). Additionally, the population fluctuation of the adult beetles during the growing season was studied for 10-yr, from 1989 through 1998, inclusively. Overwintering beetle adults mostly hibernated in the crop residue of soybean fields ([Nearly equal to]2O%) and leaf litter of woodlands ([Nearly equal to]8O%). A few beetles (
