fly control

BIOLOGICAL METHODS

Fly control by Biological methods are those which enhance and preserve naturally occurring populations of predators and parasites of flies.
The objective of biological control is to encourage naturally-occurring populations of predators and parasites to thrive. This includes the cultural step of making manure as dry and as hospitable as possible.

Using biological control, manure removal is carried out according to a staggered schedule, so that the predator and parasite populations are not decimated.
Removing portions of the manure over a period of time, preferably in the cooler season when fly numbers are lowest, preserves a portion of the parasite and predator population to reinvade the new manure.

Sometimes attempts are made to augment naturally occurring parasite populations by releasing additional individuals.Such augmentation can result in increases in the parasitism rate and reduced number of flies. However, at this time it is not possible to set quantitative guidelines as to when to release and what species and numbers to use under varying conditions.

If augmentation is attempted, it should only be carried out after taking the cultural and manure management steps necessary to maximize the naturally occurring populations of predators and parasites.

Residual surface treatments should be directed to those areas of the structures where adult flies are observed to rest. These are usually partitions and upper parts of the structure where flies rest for long periods at night.

BIOLOGICAL PEST CONTROL.

"balance of nature"

Biological pest control relies upon other living organisms (parasites, predators, and pathogens) as pest control agents. These beneficial species are an important part of the ecological balance in every natural community. In some cases, biocontrol agents are reared and released in large numbers to suppress native or introduced pests (augmentation). In other cases, careful management of the environment (conservation) is sufficient to insure the welfare of natural enemy populations. Insect species that are accidently introduced from foreign countries often become pests because they have escaped from natural enemies in their homeland. Finding and importing these natural enemies is one important part of biological control.

Another facet of biological control is the use of resistant plant (or animal) genotypes. Natural host resistance may involve defensive chemicals that inhibit growth or development (antibiosis), physical or chemical characteristics that reduce palatability (antixenosis), or genetic traits that simply reduce the extent or severity of injury (tolerance).

Biocontrol agents include a wide variety of life forms, including vertebrates, invertebrates, fungi, and microorganisms. These beneficial species are common in most natural communities and, although their presence is often unnoticed, they help maintain the "balance of nature" by regulating the density of their host or prey population. Insect species often become "pests" when this ecological balance is disrupted by natural events or human intervention.
