Ecological Risk Assessment for Chlorpyrifos in Terrestrial and Aquatic Systems in the United States // Reviews of Environmental Contamination and Toxicology Volume 231, 2014, pp 219-265,

Pollinators are crucial species of almost all natural and artificial terrestrial ecosystems (Garibaldi et al. 2013; NAS 2007). While most of the world’s food supply, including important crops such as cereals, are mainly wind pollinated, more than three-quarters of angiosperms rely on animals for pollination and approximately 75 % of the leading global fruit-, vegetable-, and seed-crops depend at least partially on animal pollination.
