Biological Control of Insect Pests in Agroecosystems: Effects of Crop Management, Farming Systems, and Seminatural Habitats at the Landscape Scale: A Review
There is a growing body of evidence to suggest that the simplification of land uses associated with a strong dependence on agrochemical inputs is decreasing environmental quality, threatening biodiversity, and increasing the likelihood of pest outbreaks. The development of farming systems with greater reliance on ecosystem services, such as biological control of insect pests, should increase th...
متن کاملThe ecological role of biodiversity in agroecosystems
Increasingly research suggests that the level of internal regulation of function in agroecosystems is largely dependent on the level of plant and animal biodiversity present. In agroecosystems, biodiversity performs a variety of ecological services beyond the production of food, including recycling of nutrients, regulation of microclimate and local hydrological processes, suppression of undesir...
متن کاملPlant Biodiversity Enhances Bees and Other Insect Pollinators in Agroecosystems. a Review Plant Biodiversity Enhances Bees and Other Insect Pollinators in Agroecosystems. a Review
Thirty-five percent of global production from crops including at least 800 cultivated plants depend on animal pollination. The transformation of agriculture in the past half-century has triggered a decline in bees and other insect pollinators. In North America, losses of bee colonies have accelerated since 2004, leaving the continent with fewer managed pollinators than at any time in the past 5...
متن کاملEvaluation of Radiation Absorption and use Efficiency in Substitution Intercropping of Sesame (Sesamum Indicum L.) and Mung Bean (Vigna Radiata L.)
Sunlight is the main source of energy in agroecosystems. Light is absorbed by leaves and this energy is stored during the process of photosynthesis in chemical bonds of organic compounds and finally converts to the plant biomass. In order to increase the efficiency of this process is necessary to be aware of how changes in light absorption in plants. From an agricultural perspective, Understand...
متن کاملWhat is the effect of soil use on ant communities?
Studies on ant communities in agroecosystems have contributed to the knowledge of the effect of agricultural activities on biological communities. The aim of this study is to explain the effect of soil use on ant communities. We tested the hypothesis that there was a decrease in ant species richness and a change in the species composition at habitats with more intense soil use. We collected ant...
