To systematically evaluate cover crop effects on cotton yield and weed suppression, we conducted a random-effects meta-analysis investigating 10 moderating variables in 104 articles, yielding 1117 independent studies over 48 years.
Data from: Knockdown of a metathoracic scent gland desaturase enhances the production of (E)‐4‐oxo‐2‐hexenal and suppresses female sexual attractiveness in the plant bug Adelphocoris suturalis
This study isolates and characterizes two new desaturase‐like genes, termed Asutdes1 and Asutdes2, from Adelphocoris suturalis, an important agricultural pest in China.
Blue Mountains Data is the area of the Malheur, Umatilla, and Wallowa Whitman National Forests combined into one data set that covers all of 3 forests. The Blue Mountains is also known as CSA4 in Region 6.

Fopius arisanus (Sonan) is a braconid wasp (subfamily Opiinae) and biological control agent of a broad range of tephritid fruit fly species, including the global pests Mediterranean fruit fly Ceratitis capitata and the Oriental fruit fly Bactrocera dorsalis. In an effort to create foundational genomic resources for this species, the complete genome and transcriptomes for several wasp life stages have been recently generated. Manual annotation of 55 viral genes and phylogenetic analysis revealed that F. arisanus has independently acquired a symbiotic virus related to alpha-nudiviruses.
Agricultural Policy/Environmental eXtender (APEX) has components for routing water, sediment, nutrients, and pesticides across complex landscapes and channel systems to the watershed outlet as well as groundwater and reservoir components. A watershed can be subdivided as much as necessary to assure that each subarea is relatively homogeneous in terms of soil, land use, management, and weather. APEX was constructed to evaluate various land management strategies considering sustainability, erosion (wind, sheet, and channel), economics, water supply and quality, soil quality, plant competition, weather, and pests. The routing of water, sediment, nutrient, and pesticide capabilities are some of the most comprehensive available in current landscape-scale models and can be simulated between subareas and channel systems within the model. APEX can perform long-term continuous simulations for modeling the impacts of different nutrient management practices, tillage operations, conservation practices, alternative cropping systems, and other management practices on surface runoff and losses of sediment, nutrients, and other pollutant indicators.
Integrated Pest Management (IPM) is a science-based, decision-making process that identifies and reduces risks from pests and pest management related strategies. IPM coordinates the use of pest biology, environmental information, and available technology to prevent unacceptable levels of pest damage by the most economical means, while minimizing risk to people, property, resources, and the environment. IPM provides an effective strategy for managing pests in all arenas from developed agricultural, residential, and public lands to natural and wilderness areas. IPM provides an effective, all encompassing, low-risk approach to protect resources and people from pests.
Invasive.org is a joint project between University of Georgia's Bugwood Network and the U.S. Department of Agriculture. Over 8,300 images, including over 1,000 new images of invasive/exotic/noxious plant, insect, pathogen and other species (including many weeds) and their biological control agents, taken by over 250 photographers. Most images were digitized from high-resolution 35mm slides. Multiple levels of jpeg format images are downloadable and may be copied and used for any non-profit, educational purpose with appropriate credit and copyright notice. Although most images are North American in nature, the system also contains images of organisms that are "Non-U.S. Natives", or are considered to be "U.S. Invasives."
