Alfalfa planted as a trap crop in strawberries to control tarnished plant bug. However, creating a farmscape of flowering plants picked at random may favor pest populations over beneficial organisms. Once information is available on key pests and their natural enemies, the following strategies can be considered:. Consider the Area to be Farmscaped.
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. Pest management systems guide [Online]. 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. 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 to Enhance Biological Control
This is where you can find research-based information from America’s land-grant universities enabled by eXtension. Try asking one of our Experts.
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.
Intercropping is the practice of growing two or more crops usually different families in the same area. Ecological engineering for pest management: Geoff Zehnder, Clemson University. The African marigold, for example, releases thiopene—a nematode repellent—making it a good companion for a number of garden crops. The timing is critical — destruction too early or too late can negate the trap crop effects or even result in mass pest migration to the cash crop.
Farmscaping aims to prevent damaging levels of pests from developing in the crop ecosystem. Pests find it easier to locate host plants when grown in a monoculture versus a mixed planting. This is a broad topic that refers to the addition of specific plants to enhance the growth and quality of nearby crops. If planting as a market crop, let some plants go to seed and overwinter to provide an abundance of flowers next season.
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.
Farmscaping: Making Use of Nature’s Pest Management Services
For example, fennel and colored yarrow varieties can be sold as cut flowers. For example goldenrod and fennel can be planted to harbor aphids that serve as hosts for early-season predator species.
Extra-Floral Nectaries are nectar glands that are not associated with flowers. Therefore, a flexible approach is needed to be able to adjust beneficial habitat according to weather conditions. This term is used because we are providing food and habitat for the top animals in the food chain, the predators and parasites. Browse related by Tag organic productioneorganic. 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. Interplantings of non-host crops may also act as a food source or habitat for beneficial organisms.
Sampling of crop plants should be done at least weekly. Nectar is a source of liquid sugar energy and vitamins for beneficials, and is critical for optimum performance.

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. Once the farmscape is in place, regular monitoring of plants will indicate whether a healthy population of beneficial insects has been established. For enhannce 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:.
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. The optimum area of the farm devoted to farmscaping depends upon the dispersion fzrmscaping of the beneficials you want to attract see Table 1 below. An excellent reference on the topic is Ecological Engineering for Pest Management: Insect sampling guidelines are available online.
Another good pollen producer is the corn plant. A trap crop is a biologiccal that is planted to lure insect pests bioolgical from the cash crop.
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. More research is needed to understand the complex interactions among pests, natural enemies, and mixed crop habitats. Planting a diversity of flowering plants to enhance biological control has farmscaoing referred to as “chocolate box ecology” because of the colorful floral display.
Flowering plants provide many of the food resources natural enemies need. This is an eOrganic article and was reviewed for compliance with National Organic Program regulations by members of the eOrganic community. Trap crops were originally designed to be used in conventional systems where insecticides could be used to kill the pests in the trap crop. Flowers that provide pollen. Annual Review of Entomology.
Likewise, natural enemies require adequate supplies of nectar, pollen and plant-feeding insects and other arthropods as food to sustain and increase their populations. This requires some information-gathering and management skill on the part of the grower, but this investment can result in the following benefits:. The supplemental nectar provided by extrafloral nectaries is important, especially during the early season or periods of drought when few plants are in bloom.
Farmacaping pest management in organic crops. Remember also that farmscaping plants can add value beyond biological control.
