Farmers Weekly 11th Sept 20 has an article about an RSPB owned commercial arable farm.
In 2019, the farm was benchmarked against other local farm businesses and though crops varied in profitability, this was typical compared to the other farms.
!n 2019, the farm went completely insecticide free and saw no reduction in yields compared with previous years, making small savings on the products.
“Though we had aphids in the beans last year, there were loads of ladybirds and larvae too, and within 10 days there were only ladybirds left and the beans didn’t suffer at all,”
The farm is planting wildflower corridors through fields to increase access to beneficial insects, compost spreading and sowing cover crops as part of the Centre of Ecology and Hydrology and Rothamsted Research’s Achieving Sustainable Agricultural Systems programme.
Bee Friendly Monmouthshire has produced a video featuring a small garden in Monmouthshire where wildlife friendly habitat has resulted in presence of a high number of bee and wasp species.
BBC Report:- “Dr Walton from University College London and colleagues monitored moth activity around ponds in agricultural areas of Norfolk.
They found that 45% of the moths they tested were transporting pollen, which originated from 47 different plant species, including several that were rarely visited by bees, hoverflies and butterflies.
The scientists found that while bumblebees and honeybees are critically important, they tended to target the most prolific nectar and pollen sources. Not so with moths.
“From what we see from our work, moths tend to be generalists, meaning they’re not specifically visiting a narrow group of flowers,” said Dr Walton. … ”
The New Scientist reports:-
“Are we witnessing an insect apocalypse? It is complicated. The longest running study of insect populations in the world shows that the total mass of moths in Great Britain is double what it was in the 1960s, but has been declining by around 10 per cent a decade since the 1980s. This probably reflects what has happened to other kinds of insects, too. …. ”
“The Pollinator Monitoring and Research Partnership (PMRP) aims to establish how insect pollinator populations are changing across Great Britain.
We are working with existing recording schemes that focus on pollinating insects, and have established new large-scale surveys under the UK Pollinator Monitoring Scheme banner (PoMS)
PoMS is the only scheme in the world generating systematic data on the abundance of bees, hoverflies and other flower-visiting insects at a national scale (currently across England, Wales and Scotland). Together with long-term occurrence records collated by the Bees, Wasps and Ants Recording Society and Hoverfly Recording Scheme, these data will form an invaluable resource from which to measure trends in pollinator populations and target our conservation efforts.
With reports of dramatic losses of insects occurring across the globe, and concern about what this means for wider biodiversity and ecosystem health, there has never been a more important time to document evidence of change in populations of pollinating insects.
FIT Counts: if you can spare ten minutes to sit and watch insects and flowers you can carry out a FIT Count (Flower-Insect Timed Count)! This simple survey collects data on the total number of insects that visit a particular flower, ideally chosen from our list of 14 target flowers. FIT Counts can be done anywhere, including gardens and parks, in warm, dry weather any time from April to September. If you can carry out several counts at one location during that time you will be adding extra value to your survey records. All the information you need is provided on their web site:”
A widespread loss of pollinating insects in recent decades has been revealed by the first national survey in Britain, which scientists say “highlights a fundamental deterioration” in nature.
“As spring approaches, Monmouthshire’s grounds maintenance service will work to support the environment and provide a boost for wildlife by modifying mowing practices. Teams will mark open spaces with blue or white topped stakes to highlight areas likely to be suitable habitats which have been identified by council staff, residents or through the council’s partnerships with local groups. These include Bee Friendly Monmouthshire, Bees for Development and Gwent Wildlife Trust as part of the Nature Isn’t Neat project funded by the Vale of Usk Rural Development Plan for Wales …”
Strips of wildflowers across farm fields could cut pesticide spraying. Guardian newspaper report:-
“The stripy fields have been planted across England as part of a trial to boost the natural predators of pests that attack cereal crops.
Long strips of bright wildflowers are being planted through crop fields to boost the natural predators of pests and potentially cut pesticide spraying. The strips were planted on 15 large arable farms in central and eastern England last autumn and will be monitored for five years, as part of a trial run by the Centre for Ecology and Hydrology…. ”
