Although crop rotation has been used for centuries to enhance agricultural production, there are surprisingly little data justifying the use of one rotation over another. Growers typically avoid growing plants in succession that belong to the same genus or...

Environmental damage from insecticide overuse is a major concern, particularly for conservation of “good” insects such as pollinators that ensure stable production of food crops like fruits and vegetables. However, insecticides are also necessary for farme...

1. Hundreds of recent studies have voiced concern over the negative impacts of non-target pesticides on pollinator health. However, pesticide loads are highly variable across agricultural landscapes and it is unclear whether pollinators exhibit behavioral...

The long-term decline of monarch butterflies has been attributed to loss of their milkweed (Asclepias sp.) host-plants after the introduction of herbicide-tolerant crops. However, recent studies report pesticide residues on milkweed leaves that could act a...
Insecticide use and insufficient forage are two of the leading stressors to pollinators in agroecosystems. While these factors have been well-studied individually, the experimental designs do not reflect real-world conditions where insecticide exposure and...
