  • pods
  • Photos 1 and 2: Tiny, immature, sterile pods on soybean from Darling Downs. (thebeatsheet.com.au)
  • These aphids feed by sucking plant sap from the leaves (Photo 1), stems (Photo 2) and pods. (uga.edu)
  • Later in the season the aphids can be found on all parts of the plant, feeding primarily on the undersides of leaves, but also on the stems and pods. (unl.edu)
  • Severe infestations can significantly reduce yields, and can also cause discolouration of pods and reduction in their saleable values. (wikipedia.org)
  • corn
  • When measuring up the 2007 season, Aaron Locker, FMC product manager, sees a batch of challenges, some unique to this time and place in corn and soybean production. (croplife.com)
  • As of 2013[update] neonicotinoids have been used In the U.S. on about 95 percent of corn and canola crops, the majority of cotton, sorghum, and sugar beets and about half of all soybeans. (wikipedia.org)
  • biology
  • S1055: Biology, impact, and management of soybean insect pests in soybean production systems. (nimss.org)
  • To address these concerns, coordinated research and Extension delivery are necessary to rapidly understand native and invasive pest biology, develop best management practices, and deliver recommendations to soybean producers. (nimss.org)
  • Therefore, coordinated, area-wide research approaches are necessary to understand their biology, develop and deliver management recommendations, and track their distribution to minimize impact on soybean production. (nimss.org)
  • insects
  • Overall yield gains are not expected from neonicotinoid seed treatments for soybean insect pests in the United States, and foliar insecticides are recommended instead when insects do reach damaging levels. (wikipedia.org)
  • Aphids, also known as plant lice and in Britain and the Commonwealth as greenflies, blackflies, or whiteflies (not to be confused with "jumping plant lice" or true whiteflies), are small sap-sucking insects and members of the superfamily Aphidoidea. (wikipedia.org)
  • Adelgids are sometimes described as aphids, but are more properly classified as aphid-like insects, because they have no cauda or cornicles. (wikipedia.org)
  • Aphids passively feed on sap of phloem vessels in plants, as do many of their fellow members of Hemiptera such as scale insects and cicadas. (wikipedia.org)
  • pests
  • However, various native and invasive insect pests whose distributions are rapidly expanding and adapting to management practices threaten soybean yield and quality. (nimss.org)
  • In the long-term, the establishment of invasive insect pests will continue to impact soybean ecosystems, including interactions with native pests and the biological control offered by various natural enemies. (nimss.org)
  • Native and historical pests of soybean continue to present challenges to producers. (nimss.org)
  • Specifically, recently introduced pests, such as brown marmorated stink bug, kudzu bug, and redbanded stink bug, pose new challenges to the North American soybean industry (Suiter et al. (nimss.org)
  • Furthermore, as these soybean pests spread to new areas, additional participants benefit from the research performed by other regions. (nimss.org)
  • Along with the changing pest complexes, soybean producers are also faced with managing pests with new tools and technologies. (nimss.org)
  • Aphids are among the most destructive insect pests on cultivated plants in temperate regions. (wikipedia.org)
  • thresholds
  • This entry was posted in Agricultural IPM , Center News , Field Crop IPM , Insect Management , Publications and tagged economic thresholds , soybean aphid . (ncipmc.org)
  • Specific research objectives include a need to develop and optimize reliable sampling methods, action thresholds, and cost-effective management strategies to maximize sustainable soybean production (e.g. (nimss.org)
  • crops
  • In a 2003 Minnesota study, soybean aphids damaged nearly 4 million acres of crops and cost Minnesota farmers about $80 million in damages. (missouri.edu)
  • He notes that Syngenta's Cruiser seed treatment is an established product here, but in a development late last year, research was able to explain the improved "plant health" demonstrated by the treatment in soybeans as well as many other crops. (croplife.com)
  • A devastating disease was observed in several paddocks of soybean crops in the Branchview area of the Darling Downs in late autumn 2016. (thebeatsheet.com.au)
  • While soybean aphids were present in the affected Downs crops, it is extremely unlikely they were responsible because aphids are not phytoplasma vectors, and soybean aphid attack has never been observed to lead to the small bunchy pod symptoms seen on the Downs. (thebeatsheet.com.au)
  • temperatures
  • Conditions that favor aphid population growth are cool temperatures, plant stress, drought stress, fields with low potassium and a lack of aphid predators. (missouri.edu)
  • As colonies expand and temperatures increase, soybean aphids move toward lower portions of the soybean plant. (wikipedia.org)
  • Foyer researches plant growth regulation and development under optimal circumstances and in conditions of stress (caused by, for example, lack of water, low temperatures, high light, infestation by aphids). (wikipedia.org)
  • Extension
  • To further underline our positive relationships with stakeholders, participants are supported by state, regional and national soybean commodity groups as well as industry to develop soybean integrated pest management (IPM) insect research and Extension activities. (nimss.org)
  • species
  • Major examples of changing soybean pest issues since the last project renewal include the emergence of new, invasive new Heteropterans (aphids, stink bugs, and Plataspids) and the geographical spread of established species. (nimss.org)
  • In contrast to many taxa, aphid species diversity is much lower in the tropics than in the temperate zones. (wikipedia.org)
  • When host plant quality becomes poor or conditions become crowded, some aphid species produce winged offspring, "alates", that can disperse to other food sources. (wikipedia.org)
  • Many aphid species are monophagous (that is, they feed on only one plant species). (wikipedia.org)
  • Others, like the green peach aphid feed on hundreds of plant species across many families. (wikipedia.org)
  • invasive
  • Invasive pest problems, such as soybean aphid (a major focus of the group over the last decade), have been and will continue to be effectively addressed by this regional project. (nimss.org)
  • The presence of soybean aphids in Georgia represents a new state record for this invasive soybean pest that is being regulated through USDA/APHIS personnel. (uga.edu)
