Farmscaping: Making Use of Nature’s Pest Management Services

Flowers or extra-floral nectaries provide nectar. Annual Review of Entomology. Flowering plants biologocal many of the food resources natural enemies need. Farmscaping aims to prevent damaging levels of pests from developing in the crop ecosystem. This section will familiarize you with key factors to consider in planning a farmscape for effective biological control, including:. The African marigold, for example, releases thiopene—a nematode repellent—making it a good companion for a number of garden crops.

Before planning the farmscape, collect as much information as possible. Recent research has shown that the quality, not quantity, of the farmscape plantings is most important. Alternative hosts for beneficial insect prey.

Interplantings of non-host crops may also act as a food source or habitat for beneficial organisms. Flowers that provide pollen. Farmscaping to enhance biological control: Example of companion planting from left to right; lettuce, cabbage and sunflower. This is where you can find research-based information from America’s land-grant universities enabled by eXtension.

For more information, refer to eOrganic’s articles on organic certification. In a pest management context companion plants are usually added to deter or repel pests. Another good pollen producer is the corn plant. Flowering medicinal plants like echinacea, fever few, and boneset also have multiple uses. Arthropod pest management in organic crops.

This term is used because we are providing food and habitat for the top animals in the food chain, the predators and parasites.

The supplemental nectar provided by extrafloral nectaries is important, especially during the early season or periods of drought when few plants are in bloom. This is a broad topic that refers to the addition of specific plants to enhance the growth and quality of nearby crops.


Fzrmscaping has shown that for a typical parasitic wasp, egg laying capacity can be 10 times greater for females given a high quality nectar diet compared with females given a poor quality diet. Extra-Floral Nectaries are nectar glands that are not associated with flowers.

More on trap crops later…. Livestock producers will tell you that their animals are healthier and reproduce more readily when provided an adequate and nutritious diet.

Planting a diversity of flowering plants to enhance biological control has been referred to as “chocolate box ecology” because of the colorful floral display. Wild parsnip left and Figure 7.

A recent study on the effects of non-host companion plants 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 factors in disrupting host location. 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.

Consider the Area to be Farmscaped. In this bio,ogical approach to on-farm pest management planning, farmscaping 2nd phase is integrated with other pest management strategies.

Welcome This is where you can find research-based information from America’s land-grant universities enabled by eXtension. However, creating a farmscape of flowering plants picked at random may favor pest populations over beneficial organisms. This requires some information-gathering and management skill on the part of the grower, but this investment can result in the following benefits:. In planning the farmscape it is important to identify specific plants, planting situations, and management practices that best support populations of beneficial organisms.

Insectary plants like mustards interplanted with market crops provide pollen and nectar to attract and maintain beneficial insects in the crop landscape. In organic systems approved insecticides can be used, but pests can also be eliminated by crop destruction.


View publishing information about this page. Parasitic and predatory insects use extrafloral nectaries as food sources and mating sites. Remember also that farmscaping plants can add value beyond biological control.

Entomologist Patricia 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. 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.

Sampling of crop plants should be done at least weekly. Alfalfa planted as a trap crop in strawberries to control tarnished plant bug. Priority is given to preventative pest management strategies like farmscaping, followed by more direct measures if preventative strategies are not sufficient.

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.

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.

Ecological engineering for pest management: These plants have small, open flowers that are accessible to the tiny mouthparts of small, parasitic wasps. Many pest populations can be managed by enhancing the efficacy and local abundance of the existing community of natural enemies through modification of the environment, a concept that has been termed “conservation biological control.

There are many different approaches and strategies in farmscaping. Likewise, natural enemies require adequate supplies of confrol, pollen and plant-feeding insects and other arthropods as food to sustain and increase their populations.
