The ‘Midgeater' device introduced by Calor in 2003 to combat biting midges causing irritation to humans, has now been successfully tested by leading scientists as a monitoring device in the fight against bluetongue.

Leading midge scientist Dr Alison Blackwell, who is the Managing Director of University of Edinburgh based Advanced Pest Solutions, presented her company's findings in her keynote speech to the Royal Entomological Society in Belfast on November 19th.

The current method of trapping midges when monitoring the deadly bluetongue virus is a light trap, but Alison and her team have established that a modified Midgeater can be more effective in catching the main midge species that carry the virus.

Alison said: "During trials this year, we found that Calor fuelled Midgeater traps modified with a simple ‘black' light source and fitted with an octenol / ammonia bait, proved to be far more effective at catching the main species of midge known to carry the bluetongue virus than the light traps which are currently used to monitor midge populations in relation to the disease".

Farmers throughout the UK recently commenced a vaccination programme to protect their animals from the only strain of the bluetongue virus that has so far been encountered in the UK, serotype 8, but there is still a real need to carefully monitor biting midge populations, as other strains of the virus are approaching our shores.

Alison added: "In the last few weeks serotype 1 and serotype 6 have been found in Northern Europe and there are currently no vaccines available in the UK for these types of the bluetongue virus, so it is important that we remain vigilant and monitor midges throughout the UK".  

Advanced Pest Solutions have tested their modified Midgeater traps in England and Wales. The English, project which was carried out at a specialist bull breeding facility, also included the use of the Barrfly air curtain, from fellow Scottish business Innovent.

Alison explained: "Innovent's air curtain is designed to prevent midges passing through it into sensitive areas. The insects simply aren't strong enough to fly through the air currents it produces.

"The air curtain, combined with the Calor supplied traps and APS's consultancy and analysis creates a comprehensive ‘assess, protect and stop', midge management system that businesses can use to reduce the exposure to the risks of midge borne diseases."
