The most successful farmscape systems eenhance been developed and fine-tuned by farmers to fit their individual circumstances. If planting as a market crop, let some plants go to seed and overwinter to provide an abundance of flowers next season.

Pollen farmxcaping a source of protein and protein is critical for egg laying. The optimum area of the farm devoted to farmscaping depends upon the dispersion capabilities of the beneficials you want to attract see Table 1 below.

Farmscaping methods include the use of insectary plants, hedgerows, cover crops, and water reservoirs to attract and support populations of beneficial organisms such as insects, spiders, amphibians, reptiles, bats, and birds that parasitize or prey upon insect pests. Peonies, sweet potato, bachelor button and lima bean are examples of plants with extrafloral nectaries located on various parts of the plant.

Researchers now commonly screen plant species and use a range of selection criteria to determine appropriate botanical composition. Consider the Area to be Farmscaped. An excellent reference on the topic is Ecological Engineering for Pest Management: Once information is available on key pests and their natural enemies, the following strategies can be considered:. Pest management systems guide [Online].

Many plants in the Umbelliferae family are good sources of pollen. Rather, it is an ecological approach or tool that can be combined with other pest management strategies as part of an integrated organic pest management program. Nectar is a source of liquid sugar energy and vitamins for beneficials, and is critical for optimum performance. Extra-Floral Nectaries are nectar glands that are not associated with flowers.


The trap crop can be a different plant species, a different variety, or just a different growth stage of the same species, as long as it is more attractive to the pests when they are present. Farmscaping is a whole-farm, ecological approach to increase and manage biodiversity with the goal of increasing the presence of beneficial organisms. However, using this approach without knowledge of key pests and the interaction among plants, pests and natural enemies may lead to failure. Geoff Zehnder, Clemson University.

Simply adding attractive flowering plants to the farmscape without knowledge of the biology and behavior of key pest and natural enemy species will not result in effective biological control.

Flowers that provide pollen. Browse related by Tag organic productioneorganic.

For more information, refer to eOrganic’s articles on organic certification. One common approach in farmscape planning is to first think biologial the intended crop, then the key pest s that are known to attack the crop, then determine the commonly occurring natural enemies of the pest sand identify appropriate food plants and harborage requisites.

However, creating a farmscape of flowering plants picked at random may favor pest populations over beneficial organisms. Sampling of crop plants should be done controp least weekly. Arthropod pest management in organic crops.

The supplemental nectar provided farmdcaping extrafloral nectaries is important, especially during the early season too periods of drought when few plants are in bloom. Follow this link to a sample budget for establishment and maintenance contro beneficial insect habitat: Entomologist Patricia Biologicap Tillman centertechnician Kristie Graham rightand student technician Brittany Giles evaluate a sorghum trap crop being used to control stink bugs in adjacent fields of peanuts and cotton.

In some situations it is useful to establish plantings that will support prey populations that can provide food for natural enemies to sustain their initial establishment into the area. This term is used because we are providing food and habitat for the top animals in the food chain, the predators and parasites. Parasitic and predatory insects use extrafloral nectaries as food sources and mating sites.

This requires some information-gathering and management skill on the part of the grower, but this investment can result in the following benefits:. An easy way to add Umbeliferae to the farmscape is to buy carrots or parsnips at the market with the tops on and plant them in the farmscape.


Assassin bugs are generalist predators; although they feed on both pest and beneficial insects they are generally considered to be beneficial.

For each market crop to be grown, make a list of the most damaging pests that require management; then for each pest, try to answer the following questions:. Flowering plants provide many of the food resources natural enemies need. Fennel both the common and bronze varieties is not only attractive to small parasitic wasps but its flowers also attract syrphid flies, lacewings, mantids, lampyrids lightning bugs and ladybugs.

For example, fennel and colored yarrow varieties can be sold as cut flowers. Before planning the farmscape, collect as much information as possible.

Farmscaping: Making Use of Nature’s Pest Management Services

In a engance management context companion plants are usually added to deter or repel pests. Trap crops were originally designed to be used in conventional systems where insecticides could be used to kill the pests in the trap crop. Wild parsnip left and Figure 7. Farmscaping to enhance biological control: Flowering medicinal plants like echinacea, fever few, and boneset also have multiple uses.

The African marigold, for example, releases thiopene—a nematode repellent—making it a good companion for a number of garden crops. A recent study on the effects of non-host companion ffarmscaping on host finding by the cabbage root fly and onion fly demonstrated that companion plant odor had little or no effect, but that plant size, leaf area and color were the most important farmsdaping in disrupting host location.

Early research demonstrated that biological control of insect pests can be achieved if significant numbers of natural enemies are present at critical times during pest development.
