Farmscaping: Making Use of Nature’s Pest Management Services – eXtension

Before planning the farmscape, collect as much information as possible. 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.

Example of companion planting from left to right; lettuce, cabbage and sunflower. Pests find it easier to locate host plants when grown in a monoculture versus a mixed planting. Geoff Zehnder, Clemson University. Once the farmscape is in place, regular monitoring of plants will indicate whether a healthy population of beneficial insects has been established. An excellent reference on the topic is Ecological Engineering for Pest Management: In this phased approach to on-farm pest management planning, farmscaping 2nd phase is integrated with other enhancf management strategies.

A trap crop is a crop that is planted to lure insect pests away from the cash crop.

For more information, refer to eOrganic’s articles on organic certification. Many plants in the Umbelliferae family are good sources of pollen. Flowers or extra-floral nectaries provide nectar.

Observation and experience are the most valuable tools in this regard. Successful use of trap crops is challenging. Alfalfa planted as a trap crop in strawberries to control tarnished plant bug. 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. cnotrol

Both practices serve to increase biodiversity and make the habitat less suitable for pest development. There are many different approaches and strategies in farmscaping. Nectar is a source of liquid sugar energy and vitamins for beneficials, and is critical for optimum performance. Strip cropping is a derivation of intercropping and is the practice of growing two or more crops in alternating strips across a field.

Therefore, a flexible approach is needed to be able to adjust beneficial habitat according to weather conditions. Likewise, natural enemies require adequate supplies of nectar, pollen and plant-feeding insects and other arthropods as food to sustain and increase their populations.

Priority is given to preventative pest management strategies like farmscaping, followed by more direct measures if preventative strategies are not sufficient. Parasitic and predatory insects use extrafloral nectaries as food sources and mating sites.

Intercropping is the practice of growing two or more crops usually different families in the same area.

If planting as a market crop, let some plants go to seed and overwinter to provide an abundance of flowers next season.

For example, fennel and colored yarrow varieties can be sold as cut flowers. Planting a diversity of flowering plants to enhance biological control has been referred to as “chocolate box ecology” because of the colorful floral display. Flowers that provide pollen.

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. Farmscaping to enhance biological control: Research 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.

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:. The African marigold, for example, releases thiopene—a nematode repellent—making it a good companion for a number of garden crops. Annual Review of Entomology. Always check with your organic certification agency before adopting new practices or using new materials.

These plants have small, open flowers that are accessible to the tiny mouthparts of small, parasitic wasps. Weather variations from year to year may strongly influence whether a particular management practice is effective. In planning the farmscape it is important to identify specific plants, planting situations, and management practices that best support populations of beneficial farsmcaping.

Extra-Floral Nectaries are nectar glands that are not associated with flowers. More research is needed to understand the complex interactions among pests, natural enemies, and mixed crop habitats.

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 farmscapiing important factors in disrupting host location. Intercropping, companion planting and trap cropping are three examples:. Alternative hosts for beneficial insect biologicao. This term is used because we are providing food and habitat for the top animals in the food chain, the predators and parasites.

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.
