This paper describes the design process of Plant Diseases and Insect Pests Information Markup Language that is used in Plant Diseases and Insect Pests Information Database of Installation Agriculture Information Platform. After analyzing and defining the basic comprising elements of plant diseases and insect pests information, the XMLSchema of Plant Diseases and Insect Pests Information Markup ...
Soil arthropod pests are those which live in the soil and cause economic loss to humans. Root maggots, wireworms, whitegrubs, termites and ants are important soil pests. Insecticides are used for the management of these pests and the buffering capacity of soil makes difficult for these pests to be managed and warrants high concentration of pesticides with repeated applications. This increases t...
Pine wilt disease is a that affects ecosystems by rapidly killing trees in short period of time due to the close interaction between three factors such as trees, mediates, and pathogens. There no 100% mortality infectious forest pests. According Korea Forest Service survey, April 2019, damage pine re-nematode was about 490,000 dead 117 cities, counties wards across country. It's fatal condition...
Combining crop plants with other plant species in agro-ecosystems is one way to enhance ecological pest and disease regulation mechanisms. Resource availability and microclimatic variation mechanisms affect processes related to pest and pathogen life cycles. These mechanisms are supported both by empirical research and by epidemiological models, yet their relative importance in a real complex a...
Empirical models are standard tools in forest management. They provide quantitative information for management and planning that is accurate within the limits of sampling and measurement accuracy, but they are generally site-specific and cannot simulate the results of changing conditions. Mechanistic, or process-based models, based on the physiological processes that govern tree growth can, in ...
Ethiopia is remarkably rich in its biological, ecological and landscape diversity and is home to outstanding natural bio-resources such as a number of herbs, aromatic and medicinal plants. The present study was carried out to study the composition, distribution and economic importance of insect pests of prioritized aromatic (Mentha sp., lemon verbena, fennel, rosemary, rosadamascene, oregano, p...
This paper presents a system for detection and recognition of pests in stored-grain based on video analysis. Unlike current systems which conduct analysis of static images, the proposed system uses video data captured by camera and performs video analysis to detect and recognize pests in grain. By using video data instead of static images, techniques such as motion estimation and multiple-frame...
