Increasingly, the public are becoming aware that not everything they have been led to believe is ultimately true.
In the past, those wrong beliefs may have influenced our purchasing choices, as well as gardening and farming practices, that ultimately shape our environment and the biodiversity within it.
When we examine the claims made and discover they are not based in fact, the truth can become more widely known, and behaviours can change - hopefully for the better!
Here are 4 key positive messages I believe are worth sharing, because they help to change opinions about insects, pesticides and farming:
These
messages are simple and can be used as sound bites. Below is
more back up information about each of these positive messages, and why
they are important.
An
interesting fact was presented at an exhibition in the Natural History
Museum in London when I last went: only 1,000 insect species are considered
‘pests’.
Take into account that there are currently 1,000,000 discovered
insect species.
In other words, of discovered insect species, only 0.1%
(that is, 1 in every 1000) are “not beneficial”.
Or put it an even better way:
999 out of every 1,000 insect species, are beneficial or benign "watchers".
Most of these 999 insects are species you are probably not aware of - (but you've long been 'educated' about aphids, vine weevils, carrot fly and lily beetles!).
Note, I had previously read that the figure for beneficial/harmless insects is 97%. Whichever figure is right, they both put insects in perspective.
Yet look in any gardening magazine around
Spring, read any literature about farming and pest control, or take a
look at the shelves in the average gardening centre, and you could be
forgiven for thinking that at least half, or even most insect species
are a BIG problem for anyone who wants to grow anything – be it flowers,
food crops, or trees and shrubs.
Indeed, I have found these views to
be felt by some of the audiences to which I have given talks about bees.
So
long as we exaggerate the threat of insects and invertebrates as 'pests', there are those who will find justification even in preventative
and successive applications of pesticides, not only in food agriculture,
but in horticulture, for use on golf courses, use by councils in public
spaces, and in our gardens.
We currently live in an age where farmers can use seeds pre-coated pesticides such as neonicotinoids, and gardeners are encouraged to treat pot plants just in case a vine weevil happens to come along.
Here's an example:
A study looking at pollen beetle prevalence (regarded
as a ‘pest’) and the application of pesticides by ADAS (an Agricultural
consultancy provider), is very revealing. It shows that farmers in the UK are treating oil seed rape with pesticide quite unnecessarily. The chart below shows 2 things:
(See ref 1 below for source)
But farmers could easily be worried by pollen beetle if they heed press releases and propaganda, such as one found in The Farmer's Guardian (UK magazine) called ‘Pollen Beetle On The Move’ (Ref 2).
Meanwhile,
other evidence suggests oilseed rape crops can recover from loss of buds through pollen beetle, which helps put the
‘danger’ in perspective (ref 3).
That’s
the conclusion of a 30 year study by the Rodale Institute,
Pennsylvania. If this is the case, it begs the question, “what kind of
chemicals do we really need to use on our farm land, and how should they be used?”
Some
agrochemical organisations claim that due to impending food shortage,
more chemicals are needed in order to produce more food. However, there
is no food shortage in the developed world, and globally, we waste a
shocking third of food produced every year – mostly in the West. Here
is a quote from a relevant UN study looking at global food wastage:

Perhaps we need to look at excess production and distribution, but I struggle to see any justification for increasing intensive agriculture practices.
Of course, some countries genuinely are experiencing
food shortage, due to global trading activity, and climate. What then?
Does this justify inhabitants of poorer countries, spending their money
on more pesticides, weedkillers and so on? Can intensive farming
practice lead to greater food security?
A report concerning
another United Nations study actually suggests that organic methods of
farming would be far more beneficial in, for example, African countries.
