The Xerces Society joined a group of environmental and health organizations to petition the California Department of Pesticide Regulation to regulate the planting of crop seeds coated with systemic insecticides. California's pesticide regulatory system has a loophole that allows for unchecked use of insecticide-coated seed on farms throughout the state. Neonicotinoid insecticides are commonly used as seed coatings, resulting in significant contamination of California's waterways and ecosystems as they move off-field.
A chemical control strategy like neonicotinoid seed treatments should only be considered when there is a potential for harm demonstrated by scouting and field history. This fact sheet evaluates use of insecticidal seed treatments for seven corn and soybean pests and offers guidance on: (a) which corn and soybean pests neonicotinoid seed treatments may be used for, (b) when scouting should occur to inform future decisions on use of neonicotinoid seed treatments, and (c) how to scout for these early season pests.
On August 18, 2020, the Xerces Society filed a petition to list the western ridged mussel as an endangered species under the U.S. Endangered Species Act. The western ridged mussel has been lost from 43% of its historic range. In addition, sudden die offs of western ridged mussels have been observed in Oregon and Washington.
The Electric Power Research Institute (EPRI) worked with the Xerces Society for Invertebrate Conservation to develop this report, which synthesizes the scientific literature and existing best management practices for monarch butterflies along with input from a survey of monarch experts and a survey of EPRI members. Monarch experts were surveyed to identify the relative benefit of specific conservation actions for monarchs as well as to provide opinions on the opportunities for power companies to engage in monarch conservation.
La luz artificial nocturna, LANA en forma abreviada, es probablemente uno de los principales causantes de la disminución de luciérnagas. La mayoría de las luciérnagas del mundo se comunican entre sí utilizando señales de luz bioluminiscente en forma de destellos, parpadeos o brillos. Estas especies están activas durante el crepúsculo o después de que anochece, de manera que las luces artificiales que se encienden durante estas horas pueden dificultar que estas luciérnagas se vean entre sí.
