Once information is available on key pests and their natural enemies, the following strategies can be considered:. More research is needed to understand the complex interactions biopogical pests, natural enemies, and mixed crop habitats.

Therefore, a flexible approach is needed to be able to adjust beneficial habitat according to weather conditions. Weather variations from year to year may strongly influence whether a particular management practice is effective.

Strip cropping is a derivation of intercropping and is the practice enhancr growing two blological more crops in alternating strips across a field. Flowering plants provide many of the food resources natural enemies need. Ecological engineering for pest management: Wild parsnip left and Figure 7. For more information, refer to eOrganic’s articles on organic certification. Peonies, sweet potato, bachelor button and lima bean are examples of plants with extrafloral nectaries located on various parts of the plant.

For example, syrphid fly adults can travel over long distances, so food plants established in just one location farmscaing support syrphids that could travel over the entire farm. This is a broad topic that refers to the addition of specific plants to enhance the growth and quality of nearby crops. Successful use of trap crops is challenging.

Alternative hosts for beneficial biologiical prey. 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. Insect sampling guidelines are available online.

In organic systems approved insecticides can be used, but pests can also be eliminated by crop destruction. 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. This section will familiarize you with key factors to consider in planning farmscapung farmscape for effective biological control, dnhance. Alfalfa planted as a trap crop in strawberries to control tarnished plant bug.

This is where you can find research-based information from America’s land-grant universities enabled by eXtension. 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.

Recent research has shown that the quality, not quantity, of the farmscape plantings is most important. Resources Find all of our great resources for organic farming.

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. 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.

Priority is given to preventative pest management strategies like farmscaping, followed by more direct measures if preventative strategies are not sufficient. Researchers now commonly screen plant species and use a range of selection criteria to determine appropriate botanical composition.

In a pest management context companion plants are usually added to deter or repel pests.

In planning the farmscape it is important to identify specific plants, planting situations, and management practices that best support populations of beneficial organisms.

Another good pollen producer is the corn plant. More on trap crops later…. Farmscaping aims to prevent damaging levels of pests from developing in the crop ecosystem. Both practices serve to increase biodiversity and make the habitat less suitable for pest development. Farmscaping to enhance biological control: An excellent reference on the topic is Ecological Engineering for Pest Management: Welcome This is where you can find research-based information from America’s land-grant universities enabled by eXtension.


Likewise, natural enemies require adequate supplies of nectar, pollen and plant-feeding insects and other arthropods as food to sustain and increase their populations. Interplantings of non-host crops may also act as a food source or habitat for beneficial organisms. For example, fennel and colored yarrow varieties can be sold as cut flowers. There are many different approaches and strategies in farmscaping.

The supplemental nectar provided by extrafloral nectaries is important, especially during the early season or periods of drought when few plants are in bloom. Before planning the farmscape, collect as much information as possible. 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.

One common approach in farmscape planning is to first think about the intended crop, then enhaance 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.

Pests find it easier to locate host plants when grown in a monoculture versus a mixed planting.

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. Livestock producers will tell you that their animals are healthier and reproduce more readily when provided an adequate and nutritious diet.
