UK GOVERNMENT TO RECONSIDER IT'S POSITION WITH REGARD TO NEONICOTINOID PESTICIDES!
Hence, the letter below has now been adapted:
Dear MP and Sir Robert (email@example.com)

NEONICOTINOIDS IMPLICATED IN HARM TO BEES
I am writing to urge you to ban neonicotinoids in light of the
recent evidence from Stirling University and France, and in line with
EDM 2664, tabled by Martin Caton MP.
I would also ask you to urgently review the regulatory system for
pesticides, and would like to point out a number of misconceptions with
regard to the regulatory system and the handling of this issue to date,
which are as follows:
Misconception 1: “The UK has a robust system for assessing risks from pesticides”
This is frequently stated by the government, but the message will simply not ‘stick’ because it is untrue:
- Like other pesticide regulatory bodies across Europe, the UK
system is constantly behind the innovation of the pesticides industry,
and currently, it is failing to adequately assess the impact of these
persistent (not easily degraded), and mobile neurotoxins.
- The system fails to consider cumulative effects
of pesticides: build up of tiny amounts of these insecticides in soil
and water over time –as stated, these chemicals persist (i.e. they are
not easily degraded), and can then be taken up by plants and
In other words, there is a risk that at some point, the
residual concentrations of neonicotinoids in the environment could
eventually build up beyond the original recommended application level!
- The system does not consider the fate of these
pesticides in the environment and possible outcomes, not to mention the
rights of organic farmers and gardeners, as well as protected and
vulnerable environments (including water ways) that could suffer
trespass from these chemicals given their mobility in soil, water and
- There is a lack of consideration for the impact
of these pesticides when combined with other chemicals in the soil and
water: such as other pesticides, fertilisers, herbicides and other
possible water treatments and common contaminants.
- The regulatory system fails to take account of
the resulting broader impact on the wider environment of killing
non-target insects (fewer than 1% of insect species are “crop pests”
For example, the percentage declines that might be expected on
various species through the food chain (such as
insect/invertebrate-eating farmland birds, already exhibiting worrying
levels of decline), and the effects of toxin build up, are not
- Scientific evidence in support of pesticides is
not independently and publicly available for review prior to marketing
authorisations being granted.
Misconception 2: “At present all evidence shows
neonicotinoids do not pose an unacceptable risk when products are used
- The regulatory system for pesticides does not adequately define the
parameter of acceptable risk in terms of the broader impact on the
environment – in other words, it does not define “acceptable risk” in
relation to the points 2, 3, 4, and 5 noted above.
- Significant and compelling evidence (see below)
indicates that even when applied correctly, and at the correct dose,
neonicotinoid pesticides are toxic for bees.
The regulatory system does
not adequately monitor the impact of sub-lethal doses and chronic and
sub-lethal effects (tiny amounts that impair normal function, ultimately
resulting in death and demise of the insect and possibly colony - even
if not immediately).
In assessing risk in the environment, the Hazard Quotient is
used to determine acute toxicity. However, this approach is completely
inappropriate to assess chronic toxicity, sub-lethal effects and chronic
effects. In addition, the system only considers the impact on honey
Where pesticides cause chronic effects, they not only affect
honey bees: the impact on non-domesticated wild species could pose a
very significant threat.
A number of important studies have been
produced highlighting chronic and sub-lethal effects of neonicotinoids
not only on honey bees, but also on wild species.
A study by Mommaerts
et al showed that “concentrations [of neonicotinoids] that may be
considered safe for bumblebees can have a negative influence on their
Therefore it is recommended that behavior tests
should be included in risk assessment tests for highly toxic pesticides
because impairment of the foraging behavior can result in a decreased
pollination, lower reproduction and finally in colony mortality due to a
lack of food”(2).
Take into account that in bumblebees, few colonies are successful
(studies indicate approximately 13.8% - 28% success rate for wild
- Unless data supplied by manufacturers is not automatically open to public scrutiny, and independently qualified prior to
the granting of marketing authorisations, how can we be confident in
the validity of the data used to assess the pesticides for
Misconception 3: Ministers will not hesitate to act however if presented with any new evidence.
The Civil Servants Code Of Practice, states: (Point 10): “You must not ignore inconvenient facts or relevant considerations when providing advice or making decisions”.
Despite the fact that significant evidence has been supplied
through the years indicating the dangers of neonicointoid pesticides and
deficiencies of the regulatory system, it seems the Precautionary
Principle has been ignored.
How many quality independent scientific
papers do the government require? Meanwhile, let me remind you that
even the EPA referred to some of the evidence submitted by Bayer in
support of the Clothianidin registration as “supplemental”. This situation simply CANNOT continue!
- The paper quoted previously by Mommaerts et al of
2010 (but published online in 2009) was edited by Dr Helen Thompson of
Fera! Why has no action been taken against neonicotinoids, to protect
wild species such as bumblebees?
Whilst we can continue to breed the
domesticated honey bee, we cannot begin to breed one of every single
invertebrate species these chemicals are putting at risk!
- A paper by Halm et al (2006)(4) states: “The
procedure to assess the risk posed by systemic insecticides to honey
bees follows the European Directives and depends on the determination of
the Hazard Quotient (HQ), though this parameter is not adapted to these
It goes on to explain how the Hazard Quotient used within the
regulatory system to assess toxicity to honey bees only considers spray
applications of pesticide, whereas neonicotinoids may be applied to soil
They then act systemically, permeating the whole plant, and
contaminate nectar and pollen. They persist in soil for years
(according to Bonmatin et al, even after application has ceased), and
can be taken up by successive plantings.
Halm et al proposed a new
system of assessing pesticides, based on the European Technical Guidance
Directive (TGD) that assesses the impact of new (793/93 and 1488/94/CE
legislations) and existing chemical substances (EC-67/54/8 and EEC-93/67
Directives) on ecosystems.
The study also highlighted that the
neonicotinoid posed a high risk for all categories of honey bees –
especially hive bees. Why has Defra not taken action to strengthen the
I would suggest to you that given the persistence in
the soil, we cannot wait for European developments in order to protect
our own ecosystem, and I note the very strong agrochemical lobby
operates on an EU level.
- Here is a list of only some of the additional
independent evidence (regarding the dangers of neonicotinoids to bees
and inadequacies of the regulatory system), that have been produced since the initial evidence was presented in the Buglife report of 2009, and yet contrary to the notion that “Ministers will not hesitate to act however if presented with any new evidence” This evidence has been ignored thus far:

To state that the conclusion from the Buglife report was that
it highlighted the need for more data on overwintering bees (as implied
by Fera and the ACP) is very far from the truth – the report went
significantly beyond that, highlighting in 2009 the need for changes to
the pesticides regulatory system, and broader consideration of the
impact of neonicotinoids and Fipronil on the wider invertebrate
population, such as wild pollinators.
(That said, when will these
studies investigating risk to overwintering bees be published and
available for public scrutiny?).
Civil servants have a duty to consider the strength of this
independent evidence as well as its quality, and also to heed the
Precautionary Principle which is enshrined in Directive 91/414 which
states that “Member States shall ensure that a plant protection
product is not authorized unless…..it has no unacceptable influence on
the environment.” “Authorizations may be reviewed at any time if there
are indications that any of the requirements….are no longer satisfied.”
I urge you to ban neonicotinoids immediately and to urgently address the inadequacies of our pesticides regulatory system.

beneficial. Around a million insect species have now been discovered:
Meanwhile, according to the British Natural History Museum, Globally,
“Only 1000 species of insect are considered to be agricultural pests.
Each year they destroy between 10 and 15 percent of the World’s
agricultural produce” – and according to the UN, we waste a THIRD
(33.333%) of food produced globally EVERY YEAR – mostly in the West.
