The Neonicotinoid Insecticides—insect Management with Seed Treatments in Corn
نویسنده
چکیده
Corn producers battle a variety of soil dwelling insect pests. Seedcorn maggots, wireworms, white grubs and several species of cutworms can attack either the seed or seedling plants and reduce the plant stand. Corn rootworm larvae feed on corn roots during midsummer and can significantly reduce the uptake of moisture and nutrients. Extensive feeding by corn rootworm larvae can reduce the roots to a point where wind causes the plants to lodge. Lodged plants slow harvest and grain yields can be reduced from both the root injury and the lodging.

Toxic and Behavioral Effects to Carabidae of Seed Treatments Used on Cry3Bb1- and Cry1Ab/c-Protected Corn
Most transgenic corn seed is now treated with systemic neonicotinoid insecticides. To address potential direct nontarget effects of these combined technologies, 16 Carabidae species from 10 genera (Agonum, Amara, Anisodactylus, Bembidion, Chlaenius, Harpalus, Patrobus, Poecilus, Pterostichus, and Scarites) Þeld-collected from corn were directly exposed to Bacillus thuringiensis (Bt) Cry toxin-l...
متن کاملConventional and seed-based insect management strategies similarly influence nontarget coleopteran communities in maize.
Seed-based pest management tools, such as transgenes and seed treatments, are emerging as viable alternatives to conventional insecticide applications in numerous crops, and often occur as coupled technologies. Seed-based technologies have been readily adopted in maize, for which ecological studies are needed to examine effects to farmland biodiversity. We compared the response of nontarget col...
متن کاملPlanting of neonicotinoid-coated corn raises honey bee mortality and sets back colony development
Worldwide occurrences of honey bee colony losses have raised concerns about bee health and the sustainability of pollination-dependent crops. While multiple causal factors have been identified, seed coating with insecticides of the neonicotinoid family has been the focus of much discussion and research. Nonetheless, few studies have investigated the impacts of these insecticides under field con...
متن کاملContamination of wild plants near neonicotinoid seed-treated crops, and implications for non-target insects.
Neonicotinoid insecticides are commonly-used as seed treatments on flowering crops such as oilseed rape. Their persistence and solubility in water increase the chances of environmental contamination via surface-runoff or drainage into areas adjacent to the crops. However, their uptake and fate into non-target vegetation remains poorly understood. In this study, we analysed samples of foliage co...
متن کاملEvaluating the Role of Seed Treatments in Canola/Oilseed Rape Production: Integrated Pest Management, Pollinator Health, and Biodiversity
The use patterns and role of insecticide seed treatments, with focus on neonicotinoid insecticides, were examined for canola/oilseed rape production in Canada and the EU. Since nearly all planted canola acres in Western Canada and, historically, a majority of planted oilseed acres in the EU, use seed treatments, it is worth examining whether broad use of insecticidal seed treatments (IST) is co...
