🐝🐝New Paper!! 🐝🐝
Do measures to reduce pesticide impacts on bees actually work?
Answer: We have no idea!

Farmers are told to do lots of things to make pesticide applications safer for bees. We looked at if they were supported by scientific evidence.

New paper out in Environmental Pollution! We found that bumblebees exposed to an acute dose of the novel insecticide flupyradifurone had impaired colour and olfactory learning/memory. Thread below. https://t.co/txnAgkbaik @felicitymuth (1/11)

We need better data on pesticide use! The EU is lagging behind other territories in how we report where pesticides are used. Here we present our proposal on how to fix this, and why it's important to do so

Really happy to present our new paper published in @Nature . We use meta-analysis to show that interactions between agrochemicals, poor nutrition and parasites interact synergistically to increase bee mortality. Start of thread (1/13). https://t.co/dd5gqOCPJJ

[Dave Goulson @DaveGoulson]

It is bonkers that we spray poisons harmful to wildlife and ourselves in our streets, gardens, even playgrounds - all in the name of tidyness. Time to stop! Please sign and RT if you agree

What is the impact of new insecticides like sulfoxaflor on bumble🐝health? In the 1st paper from his PhD🍾 @albertolinguad1, with Cristiana Rizzi & Sarah Villa, and as part of @poshbee_eu, used a novel approach to show that these are worryingly high https://t.co/mO2jYTmpwH 🧵1/14

What is the point of #PMQs if PM doesn't even attempt to answer the question?

Total evasion on why he didn't sack Hancock & insulting non-answer to my question on amending #EnvironmentBill to make halting nature loss by 2030 a legal requirement

Completely & utterly useless

@EdStrawBio https://t.co/ZY1RpKExNF

this paper says FPF is registered in >30 countries. No reference though.

[Ed Straw @EdStrawBio]

Anyone got any official data on sulfoxaflor or flupyradifurone sales/usage? Struggling to find any data whatsoever on their usage

[Guy Mercer @guy_mercer1]

@StevenFalk1 ah brilliant thank you very much.

[Guy Mercer @guy_mercer1]

Can someone help me identify this bee? @StevenFalk1?

iNaturalist is giving me Orange-legged Furrow Bee but I'm not sure how accurate this is. Any help would be appreciated.

Who's doing #NoMowMay?! 🙋 Simply leave a patch (or all!) of your lawn and see what grows!

This is a very bad idea @MandSnews:

- honey #bees are not as important as wild #pollinators such as bumblebees

- honey bees compete with wild pollinators for nectar and pollen

- this plan could negatively affect pollinator biodiversity

- honey bees are not endangered!
