| "It is not clear, based on current research, whether pesticide exposure is a major factor associated with US honeybee health declines in general, or specifically affects production of honey or delivery of pollination services," the report said. | "It is not clear, based on current research, whether pesticide exposure is a major factor associated with US honeybee health declines in general, or specifically affects production of honey or delivery of pollination services," the report said. |
| "It is clear, however, that in some instances honeybee colonies can be severely harmed by exposure to high doses of insecticides when these compounds are used on crops, or via drift onto flowers in areas adjacent to crops that are attractive to bees." | "It is clear, however, that in some instances honeybee colonies can be severely harmed by exposure to high doses of insecticides when these compounds are used on crops, or via drift onto flowers in areas adjacent to crops that are attractive to bees." |
| The report, based on a large conference of scientists last October, said more research was needed to determine the effects of pesticide exposure. | The report, based on a large conference of scientists last October, said more research was needed to determine the effects of pesticide exposure. |

| "We've got so much research on neonicotinoids now that all point to major impacts on honey bees and other beneficial insects," said Scott Hoffman Black, director of the Xerces Society, which works for the conservation of invertebrates. "It was fine to lay out the many issues that affect honeybees but I do think they missed an opportunity to really lay out the very potentially negative impacts of neonicotinoids." | "We've got so much research on neonicotinoids now that all point to major impacts on honey bees and other beneficial insects," said Scott Hoffman Black, director of the Xerces Society, which works for the conservation of invertebrates.

| But she said a limited ban on pesticides – such as that one endorsed by the EU – would at least buy time for bee populations to recover, while scientists seek out other remedies. "The bees are in a crisis situation and therefore so is agriculture, and so you take the action that can be taken now," she said. "If you already know that neonics are part of the problem then you need to get rid of them." | But she said a limited ban on pesticides – such as that one endorsed by the EU – would at least buy time for bee populations to recover, while scientists seek out other remedies.

| The class of pesticides known as neonicotinoids came on the market in the 1990s as a less toxic – to humans – form of pest control. They were widely adopted and are used on about 100m acres of crops today. | The class of pesticides known as neonicotinoids came on the market in the 1990s as a less toxic – to humans – form of pest control.
