“Use of a common pesticide in spring could have an impact on wild bumblebees by interfering with their life cycle, a UK study suggests.
The team, who looked at wild bumblebees caught in the English countryside, say the insecticide, thiamethoxam, reduces egg development in queen bees.
They say this is likely to reduce bee populations later in the year.
Thiamethoxam is one of three neonicotinoid insecticides currently restricted for use by the EU.They have been restricted amid concerns about their impact on wild bees.
The study, published in Proceedings of the Royal Society – B, investigated the impact of thiamethoxam on four species of bumblebee queen which had been captured in the wild in spring.”
