Catalog of Beneficials -- Fly Control

Overview: Search And Destroy Control For Flies

Start regular releases of parasitic wasps when flies appear in the spring so colonies can reproduce and build up on the first generations of flies. Regular fly parasite releases during warm months combined with optional trapping of adult flies and minimizing fly breeding habitat constitute an effective, economical fly control program. Good early fly control is easier than attacking a population that has gotten out of control. Prolific and adaptable Muscidifurax raptorellus and aggressive Muscidifurax zaraptor are mixed with hardy Spalangia cameroni. Durable release stations are available to protect fly parasites.

Fly Parasite Release Stations

Polypropylene plastic mesh cylinder to safely hold fly parasites for release, can be hung with bail, strapped onto a pipe or hung on a screw, hang 3-5 ft above ground. Place small handful of FP in each container each shipment. When full, empty and start over. Place cylinders around fly breeding sites, near where fly maggots are found, every 100 ft or so, 5-10/acre.Station protects FP from predators, birds, being trampled under foot, so your fly parasites – FP may continue to emerge over 3 week period.

FLY PARASITE SCHEDULES
Arrange for shipments to arrive every 1, 2, 3 or more weeks through the fly season. Choose between two levels of price savings—shorter schedules of at least 4 shipment dates and longer schedules of at least 16 shipment dates with more discount. Feel free to increase or decrease the number of bags and make adjustments in shipping dates as needed

Estimating Numbers of Fly Parasites to Order

A standard FP10 unit contains a minimum of 10,000 fly pupae from which 20,000 adult parasites will emerge. Factors affecting recommended numbers of parasites: numbers of flies, amount and wetness of manure or other organic matter for fly breeding, temperature, humidity, naturally-occurring beneficial controls, incoming migrations and use of bait traps. Starting guidelines are based on 500 to 1,000 parasites per large animal per month depending on concentration or amount of manure. Use two parasites per small animal per month. Double up when fly problems are severe and cut back when the parasites are well-established and the weather is cooler and drier.

Compost operation at North Carolina Zoological Park uses fly parasites from Rincon-Vitova Insectaries

At North Carolina Zoological Park, most animal manure is composted. George uses fly parasites to find flies breeding around pile edges and hard to clean places.

 

Schedules and numbers of units used in some typical seasonal programs: (1 unit = 1 FP10)

 

Area Rate Frequency Amount suggested
Stables 100 parasites/horse every 2-4 weeks 1-4 units/month for up to 30 horses
Feedlots 250 parasites/head every 1-2 weeks 7-10 units/week for 1,000 head
Dairies 200 parasites/cow, 1,000/calf weekly during 5-7 units/week for 100 cows
Poultry breeders 6 parasites/bird weekly 5 units/week for 10,000 breeders
Poultry layers 4 parasites/bird weekly 1 unit/week for 10,000 layers
Compost 500-1,500 parasites/cu. yd monthly 5-15 units/month for 100 cubic yards

To develop a basic release program, increase or decrease suggested release rates based on these factors:

Factor

Increase

Decrease

number of flies high low
manure or organic matter a lot little
manure moisture content wet dry
control measures established no existing program good program
rain regularly little
humidity damp dry
drainage could be better good
animal watering equipment leaky no leaks
temperature hot cool
existing biocontrols (i.e. beetles, mites & fungi) few many
bait traps don’t use use
flies migrating in yes no
flies hauled in (i.e. to composting sites) yes no
comfort level with flies low higher
neighbor’s comfort level with flies low higher
budget for control good low
health concerns yes no

ODOR MANAGEMENT

Odor is the way many insects locate food and sites to lay eggs. If you control odor from decomposing organic matter you can decrease flies attracted to scatole from fermenting manure and alcohols from fermenting sugars. Also, consider animal health and worker comfort in areas with strong odors. Odor can be a sign that a biological process has gone wrong and can benefit from some managerial attention.

There are several ways to decrease odor:
  • Change conditions (i.e. drying) to stop decomposition.Shift decomposition process, such as with acid, inoculants, or composting, away from anaerobic microbes that live without oxygen and produce bad odors to aerobic microbes that need oxygen and give off pleasant odors.
  • Intercept and neutralize odors in the air (see Bioworld Odor Neutralizer below).
