Effect of Chronic Neonicotinoid Insecticide Exposure upon Monarch Development
The long-term viability of monarch butterfly ( Danaus plexippus ) populations in North America is in doubt.
Risk of Adult Mosquito Control Pesticides to Imperiled Butterflies
Mosquito control on Department of the Interior (DOI) managed lands is a resource management challenge. The pesticides used to control mosquitoes may also affect nontarget organisms whose conservation is one of the primary responsibilities of resource managers.
Monarch Butterfly Utilization of Milkweed Plants Grown in Close Proximity to Corn Treated by a Neonicotinoid Insecticide (Seed Treatment)
Monarch butterfly populations have declined sufficiently to result in noticeably fewer overwintering at sites in central Mexico as in California.
An Inventory and Comparative Study of Bees, A Keystone Ecological Group in the Endangered Coastal Prairie of Louisiana
Much of Louisiana's coastal prairie has been converted to rice and sugarcane cultivation. USGS is inventorying bee populations in these areas to explore how effective restoration efforts have been.
Pollinator Germplasm as a Genetic Resource for Conservation
Honey bee colony failure is primarily due to the infestation of mites and agricultural pesticides, including neonicotinoids. USGS researches the impacts these have on honey bee reproductive capabilities.
Mosquito Control Pesticide Impacts to Butterflies: Implications for Imperiled Butterfly Conservation on a National Wildlife Refuge
USGS researchers evaluate the impact of a pesticide on two imperiled butterfly species in the Florida Keys.
