Super pest survives winters

Diamondback Moth: Resistent to pesticides and winter weather

A ‘SUPER PEST’ moth resistant to a class of common plant protection is now also capable of surviving through the UK’s cold winter conditions, according to new research.

Diamondback moths have arrived in their tens of millions in the past few days with more expected. Crop experts have warned the animals could have a devastating effect on cabbages and other vegetables

Diamondback moth (DBM) caterpillars feed on crops including cabbage, broccoli, swedes and Brussels sprouts, causing cosmetic damage, which could result in the loss of up to 100% of the crop. Brassicas were worth more than £200m to UK agriculture last year.

The pests, which have developed resistance to the pyrethroid class of plant protection products often have reduced fitness levels so don’t survive through winter. However, experts from Rothamsted Research and AHDB are concerned because this is not the case with this new strain of moth.

Growers are being asked to submit samples of the DBM either when seen through winter, or in spring when numbers start to rise, to aid the continued monitoring and development of control strategies to manage the pest.

Dr Dawn Teverson, Knowledge Exchange Manager at AHDB, said: “This new research reconfirms what we found last year. It’s important that Brassica growers are aware of this pyrethroid resistance and plan their crop protection programmes to treat against diamondback moths, accordingly.

“If pyrethroids are used, not only does this now fail to control DBM but it could also kill beneficial insect predators which would naturally help control the pest, further exacerbating the problem.”

Pyrethroid resistant DBM have been found overwintering on swede crops grown under insect netting.

Dr Steve Foster, research entomologist at Rothamsted Research, said: “We have seen in aphids that those which have developed resistance may not survive the winter, however this doesn’t seem to be the case with this new strain of DMB.

“The identification of pyrethroid resistance in this season’s population of moths suggests that they are descendants of 2016’s migrating diamondbacks and therefore that the resistance hasn’t stopped them from surviving over winter.”

Andrew Rutherford, farm and agronomy manager at K. S. Coles, said: “This study has been extremely helpful to growers, allowing them to increase their understanding of the pests they are trying to control and which actives will be effective.”

The diamondback moth is often described as a ‘super-pest’ because it has a rapid lifecycle, providing more opportunities for resistance to develop through gene mutation. In 2016, Steve Foster at Rothamsted Research tested three diamondback moth samples for resistance from Lincolnshire, Suffolk and Scotland. All three samples were resistant to pyrethroids.

AHDB’s co-funded project ‘FV 344a Monitoring and Managing Insecticide Resistance in UK Pests’ is currently due to end in March 2018.

Appeal for dog walkers to keep pets under control during lambing season

Published

on

THE LAMBING season is upon us and with many public paths crossing fields of sheep, the Pembrokeshire Coast National Park Authority is appealing to dog walkers to follow best practice when out in the countryside.

While walking the Pembrokeshire Coast Path National Trail and other public footpaths and bridleways:

Always keep dogs on a short lead and under close control when sheep or any other livestock are present.
Clean up after your dog; bag it and bin it wherever you can or take it away –please do not leave poo bags in the countryside.

National Park Authority Public Rights of Way Officer, Meurig Nicholas said: “If your dog is out of your sight or left out of control, it may chase after, attack or worry sheep. Worried and stressed pregnant sheep can miscarry or abort their lambs.

“Young lambs are also very vulnerable at this time, and can get distressed and even die if they are separated from their mothers or abandoned after being chased by dogs.”

There have also been incidents where dogs have had to be rescued from cliffs because they were not kept under close control.

Mr Nicholas added: “These situations have resulted in emergency services such as the Coastguard and RNLI having to retrieve and rescue dogs. These incidents are avoidable and add unnecessary pressure to our busy emergency services.”

Plan for ‘collaborative approach’ to tackling rural crime issues

Published

on

THIS week (Mar 9) Police and Crime Commissioner Dafydd Llywelyn chaired a strategic meeting with key stakeholders to identify collaborative opportunities to tackle rural and wildlife crime in the Dyfed-Powys area.

Following a meeting with the Farming Unions in Wales earlier this year, Police and Crime Commissioner Dafydd Llywelyn is keen to establish a Strategic Partnership Working Group with key stakeholders that will aim to identify ways of working collaboratively to tackle some of the rural and wildlife crime issues in Dyfed-Powys.

Dyfed-Powys Police have recently appointed a Sergeant for the Rural Crime Team, and the Police and Crime Commissioner has been keen to consult with key stakeholders to gain an input from partners to support the development of a new Rural Crime Strategy for the Force.

Key Stakeholders that were invited to be part of the strategic group include both NFU Cymru and FUW unions, as well as local authorities, National Parks, RSPCA and many others.
Police and Crime Commissioner, Dafydd Llywelyn said: “I had positive discussions with representatives from both unions earlier this year to highlight some of the rural crime issues in the Dyfed-Powys area.

“One of the priorities identified was the need to take a collaborative approach to tackling rural and wildlife Crime, and the meeting with several key partners today was an opportunity to develop discussions and ideas further”.

Earlier in March, PCC Dafydd Llywelyn published a Rural Crime bulletin, which highlights some of the work that has taken place recently in the Dyfed-Powys area, and cross border collaborative initiatives.

PCC Dafydd Llywelyn noted that this multi agency partnership will aim to build on some of the great work that is already happening, and said;  “This meeting today comes a year on from the successful St. David’s Day Conference focusing on Rural Crime that I held at Police Headquarters last year. The last 12 months have been like no other but sadly crime and incidents affecting the rural community have continued.

“Today’s multiagency Strategic meeting was an opportunity to present the new Sergeant for the specialist team, and to discuss a new website that we are developing in partnership with North Wales Police to provide key crime prevention messages to the agricultural industry – the Future Farms Cymru initiative.

“I’m grateful to all partners who attended the meeting today, and I now look forward to take all comments on board as we look to re-energise and refocus the work of the Dyfed Powys Rural Crime Team.”

NFU Cymru ‘responds robustly’ to WG

Published

on

NFU CYMRU has said that many proposals within the Welsh Government and Defra’s Welfare in Transport consultation will cause significant disruption to livestock transportation in the UK.

In a robust response to the joint Welsh Government / Defra consultation, the union has stressed the significant impact the proposals would have on the livestock and poultry sectors, and raised concerns that if the proposals are implemented, they will fail to deliver any meaningful benefit to animals’ welfare.

Wyn Evans, NFU Cymru Livestock Board Chairman said: “In order to ensure the best possible welfare outcomes, the main priorities should be the animal’s fitness to travel, loading and unloading, driver training and experience, rather than the length of the journey or the external temperature at the time of transport.

“We firmly believe that the current regulations for domestic transport already deliver high welfare, as a result of the standards, cleanliness and adaptability to different weather conditions of transport boxes in the UK. But as an industry, we want to strive for even better. We believe that in order to do that there should be more focus on certified training and providing clearer, sector-specific guidance, particularly during loading and unloading rather than what is proposed in the consultation. Good welfare and healthy livestock go hand in hand; safe arrival at a destination, be that at market or abattoir, must be and is a priority.

“The transporting of livestock is an integral part of UK food production. The suggested changes to journeys based on duration and weather conditions would cause serious delays and disruption, potentially damaging welfare outcomes, while changes to vehicle requirements would add significant costs. It will also lead to many more journeys being made, increasing greenhouse gas emissions, which work against both farming’s and the government’s net-zero targets.

“Turning to the part of the consultation on live exports, we have inputted our views into a proposed NFU assurance scheme, which is detailed in an appendix in the response. This would be extremely effective in delivering welfare outcomes at the same time as maintaining this trade, as assessing the animals’ health and reporting back to producers is a fundamental part of the scheme.”

Richard Williams, Chairman of NFU Cymru’s Poultry Group said: “Looking at the month of January for example, over the last three years on average there were 10 days where temperatures were five degrees or less. If the proposals were implemented to stop transport at this temperature, no broilers could be collected off-farm in those days. If we had a prolonged cold snap; this would have a massive effect on the food chain.

“With any policy developments government makes, it is essential they are based on the latest evidence.  We have an industry to be proud of, with world-leading standards, and that includes our current transportation requirements for all farmed livestock.”
