Neonics are insecticides. Insecticides kill insects. Bees are insects.

Bees are a special problem because they collect nectar and then concentrate everything in the nectar. That includes any insecticide. This is then fed to small larvae which due to their size are exceptionally vulnerable.

That said, politics and money get involved and the result can be a problem.

DDT is also a insecizide and help mankind so much!

Hi Timothy Ebert, but why than NOT ALL INSECIZIDES are prohibtied? There must be big differences. THERFORE I asked for PRACTICAL SCIENTIFIC results!

Do you mean the following scientific publication is not a serious scientific fact

CONCLUSION:

It is concluded that dietary neonicotinoids cannot be implicated in honey bee declines.

Dietary traces of neonicotinoid pesticides as a cause of population declines in honey bees: an evaluation by Hill’s epidemiological criteria James E Cresswell, Nicolas Desneux and Dennis vanEngelsdorp

Neonicotinoids possess different levels of toxicity which affects the life of insects (including bees). I am attaching here a sample of research papers and reviews that will give you more information.

Hi Bruno, thank you in advance for the papers, i will study them.

One problem is that insecticides are not operating in isolation. Yet it is also true that most laboratory studies isolate specific effects. One temperature, one insecticide, artificial diet yet in the field there are daily temperature fluctuations, many pesticides, and a variety of nectar and pollen sources.

Regarding DOI 10.1002/ps.3290

It is taking a bit of time looking at the citation therein. My personal opinion is that insecticides harm insects, and bees are insects. Therefore, the assumption must be made that imidacloprid will harm bees. It then becomes a debate about whether the effect is great enough given other stressors to warrant concern.

My preliminary evaluation of several bee studies conducted with NEONICS on the prohibition of plant protection shows that most experiments were NOT conducted directly with beehives in practice. The bee experiments with NEONICS were only carried out in sectoral experiments on isolated bees which did not reflect the practice. The isolated statements are therefore only sectoral valid and not global and therefore not evidence-based for practice!

These facts are above fully confirmed by Mr EBERT. So there is no holoistic knowledge, as these studies are not linked to a general valid evidence.

Think about that comparison:

Even in a state, electricity is NOT turned off, even if highly dangerously produced electricity by nuclear power and coal-fired power with climate-relevant CO2 is used.

Even cars are still not banned, even if many inhabitants die of fine dust caused by the rubber abrasion of the tyres and the abrasion of the road surface!

Hi Johann, my colleagues recently demonstrated that field levels of neonicotinoids cause increased mortality and reduced immunocompetence of workers when they are also challenged with Nosema.

I think the paper is available on Julia Grassl’s ResearchGate profile.

Grassl et al. (2018). Synergistic effects of pathogen and pesticide exposure on honey bee (Apis mellifera) survival and immunity. Journal of Invertebrate Pathology, 159, 78-86.

I hope this helps answer your question.

Best wishes,

Jessica

The cars comparison is not valid. You know the dangers from cars, and choose that anyway. You know the danger from alcohol and tobacco, yet (many) choose that anyway. Just because we want to be self-destructive does not mean that everyone feels that way.

The electricity is (in some places) made from wind, solar, and other renewable resources. It is a choice for some either as individuals or just how their utility company operates.

I recently stumbled upon this documentary on neonicotinoids. Title is "Bayer and the bees''. It's worth watching.

Thanks for your info!

Neonicotinoids like Imidacloprid , Thiacloprid, Acetamiprids etc. are poisonous to honey bees at higher concentrations.Hence must be used carefully.

Hi dear sir please find following article. You can find toxicity of neonicotinoids to hone bees and other pollinators, predator's and other beneficial insects. More interestingly this article would be help you to evaluate toxicity of neonicotinoids in GMO crops. Thank you.
