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. More on trap crops later….

For example, syrphid fly adults can travel over long distances, so food plants established in just one location could support syrphids that could travel over the entire farm. Assassin bugs are generalist predators; although they feed on both pest and beneficial insects they are generally considered to be beneficial. Farmscaping is a whole-farm, ecological approach to increase and manage biodiversity with the goal of increasing the presence of beneficial organisms.

Entomologist Enhsnce Glynn 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.

Flowers that provide pollen. Sampling of crop plants should be done at least weekly.

Pollen is a source of protein and protein is critical for egg laying. Ecological engineering for pest management: Livestock producers will tell you that their animals are healthier and reproduce more readily when provided an adequate and nutritious diet.


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. Try asking one of our Experts. Ideal farmscape plantings provide food and shelter for beneficial organisms, suppress weeds, and grow in close proximity to the cash crop without competing for space light, water and nutrients. For example goldenrod and fennel can be planted to harbor aphids that serve as hosts for early-season predator species.

Both practices serve to increase biodiversity and make the habitat less suitable for pest development. Pests find it easier to locate host plants when grown in a monoculture versus a mixed planting.

Farmscaping: Making Use of Nature’s Pest Management Services

Likewise, natural enemies require adequate supplies of nectar, pollen and plant-feeding insects and other arthropods as food to sustain and increase their populations.

However, creating a farmscape of flowering plants picked at random may favor pest populations over beneficial organisms. Parasitic and predatory insects conhrol extrafloral nectaries as food sources and mating sites. This is an eOrganic article and was contrlo for compliance with National Organic Program regulations by members of the eOrganic community.

The trap crop can be a different plant species, a different variety, or just a different growth stage of the same species, as long conrrol it is more attractive to the pests when they are present. The African marigold, for example, releases thiopene—a nematode repellent—making it a good companion for a number of garden crops.

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.

Advances in Habitat Manipulation for Arthropods Once the farmscape is in place, regular monitoring of plants fagmscaping indicate whether a healthy population of enhhance insects has been established. The supplemental nectar provided by extrafloral nectaries is important, especially during the early season or periods of drought when few plants are in bloom.


Once information is available on key pests and their natural enemies, the following strategies can be considered:.

Cotrol trap crop is a crop that is planted to lure buological pests away from the cash crop. For more information, refer to eOrganic’s articles on organic certification. Flowering medicinal plants like echinacea, fever few, and controp also have multiple uses.

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. To attract small parasitic wasps or ladybugs with a much more limited range, it is necessary to establish food plants in several areas of close proximity to the crop.

Intercropping, companion planting and trap cropping are three examples:. Recent research has shown that the quality, not quantity, of the farmscape plantings is most important. 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. Trap crops were originally designed to be used in conventional systems where insecticides could be conrol to kill the pests in the trap crop.

Insect sampling guidelines are available online.
