Flies could cost pig & poultry farmers 10% in lost growth rates and egg production.
There are 7,000 species of flies in the UK, but only 20 cause issues for livestock. Flies are the most common ectoparasite for most farmers.
Did you know that the lifecycle of flies is dependant on temperature? Flies can reproduce year-round in warm conditions, but their life cycle becomes shorter as the temperature increases. The life cycle takes 50 days from egg laying to adult at 16°c. This decreases to 16 days at 25°c and 7 days at 35°c. As the temperature of pig and poultry units are heated all year round (between 16°c and 36°c), they are the perfect location for flies to flourish!
When the flies hatch, breeding is their first priority – more so than eating! Within 48 hours of hatching, they can begin laying eggs. The lay 100-150 eggs at a time and they can lay 4 or 5 times during their short lifespan. You can see how infestations explode so rapidly!
When Dr Kai Sievert spoke at the 2015 PestEx event, he reported on a research study that compared the growth rate of pigs in housing with an untreated, moderate fly infestation (6-21 flies trapped on glue traps per day) and in housing where the flies were controlled. The pigs were finished in 109 days in the systems where the flies were controlled, compared to 121 days in the housing where they aren’t – an increase of 11%! Dr Sievert estimated that the feed cost savings were €15,000 per pig house in treated housing with a capacity for 1500.
Flies aren’t only an issue for pig producers. For poultry farmers, house flies (Musca domestica) bring the threat of cestodosis which can reduce egg production by 10%. Flies can spread the bacteria which causes Summer Mastitis, which can cost up to £300 per case to treat. In calf-rearing systems, infestations of biting flies (Stomoxys calcitrans) were over 100 flies per calf, weight gain can be reduced by 20% in beef units. It is common for between 1 and 3% of sheep in a flock to be affected by flystrike, which is a devastating and sometimes fatal condition caused by maggots.
Only 15% of the total fly population is made up of adult flies at any one time, it is essential that an integrated fly control system is used. If an adulticide is used solely, the eggs, maggots and pupae will reinfest your buildings quickly.
