Even sublethal insecticide dose may disrupt pollinator mating process

Insecticides can help protect crops against troublesome pests, but they also pose a risk for beneficial insects such as pollinators. A new study led by researchers at Penn State provided insight into how even sublethal doses of insecticides can negatively affect pollinators by disrupting the mating process.
