Naled and dichlorvos in water and aquatic organisms from a canal and rice fields near Sacramento, California
July 29, 2022
Ultra-low volumes of naled are applied by aircraft over rice fields and canals to reduce adult mosquito populations near Sacramento, California. Each summer, the pesticide is applied approximately 7-10 times between July and October. Naled and its major degradate (dichlorvos) were quantified in water, biofilm, and invertebrates following aerial applications. In 2020, samples were collected before the naled application season, after 3 rice field and 5 canal applications, and immediately after an application. In 2021, water and crayfish samples were collected before the naled application season, after 3 applications, and at intervals (1, 3, 5, and 7 days) following an application. A few opportunistic samples (including dragonflies and [...]

Field assessment of Naled and its primary degradation product (dichlorvos) in aquatic ecosystems following aerial ultra-low volume application for mosquito control
Naled, an organophosphate insecticide, is applied aerially at ultra-low volumes over aquatic ecosystems near Sacramento, California, USA, during summer months for mosquito control. Two ecosystem types (rice fields and a flowing canal) were sampled in 2020 and 2021. Naled and its primary degradation product (dichlorvos) were measured in water, biofilm, grazer macroinvertebrates, and omnivore/predat
