Weather variations from year to year may strongly influence whether a particular management practice is effective. Observation cobtrol experience are the most valuable tools in this regard. 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. Intercropping, companion planting and trap cropping are three examples:. Flowers that provide pollen.
Farjscaping supplemental nectar provided by extrafloral nectaries is important, especially during the early season or periods of drought when few plants are in bloom.
Many plants in the Umbelliferae family are good sources of pollen. 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 fagmscaping peanuts and cotton.
Parasitic and predatory insects use extrafloral nectaries as food sources and mating sites. Ecological engineering for pest management: Wild parsnip left and Figure 7.
Welcome This enhaance where you can find research-based information from Buological land-grant universities enabled by eXtension. In planning the farmscape it is important to identify specific plants, planting situations, and management practices that best support populations of beneficial organisms.
Once the farmscape is in place, regular monitoring of plants will indicate whether a healthy population of beneficial insects has been established. Assassin bugs are generalist predators; although they feed on both pest and beneficial insects they are generally considered to be beneficial. Planting a diversity of flowering plants to enhance biological control has been referred to as “chocolate box ecology” because of the colorful floral display.
One common approach in farmscape planning is to first think about the intended crop, then the 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.
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. This is an eOrganic article and was reviewed for compliance with National Organic Program regulations by members of the eOrganic community. Insectary plants like mustards interplanted with market crops provide pollen and nectar to attract and maintain beneficial insects in the crop landscape.
Geoff Zehnder, Clemson University. Both practices serve to increase biodiversity and make the habitat less suitable for pest development. This section will familiarize you with key factors to consider in planning a farmscape for effective biological control, including:.
Flowering plants provide many of the food resources natural enemies need. Advances in Habitat Manipulation for Arthropods If planting as a market crop, let some plants go to seed and overwinter to provide an abundance of flowers next season. More on trap crops later…. Farmscaping is a whole-farm, ecological approach to increase and manage biodiversity with the goal of increasing the presence of beneficial organisms.

Annual Review of Entomology. Successful use of trap crops is challenging. Pest management systems guide [Online]. In a pest management context companion plants are usually added to deter or repel pests. In organic systems approved insecticides can be used, but pests can also be ho by crop destruction.
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. For more information, refer to eOrganic’s articles on organic certification.
There are many different approaches and strategies in farmscaping. Flowering medicinal plants like echinacea, fever few, and boneset also have multiple uses.

Another good pollen producer is the corn plant. Consider the Area to be Farmscaped. Remember also that farmscaping plants can add value beyond farmscaling control. This is where you can find research-based information from America’s land-grant universities enabled by eXtension. This requires some information-gathering and management skill on the part of the grower, but this investment can result in the following benefits:.
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.
Flowers or extra-floral nectaries provide nectar. Researchers now commonly screen plant species and use bkological range of selection criteria to determine appropriate botanical composition.
Farmscaping: Making Use of Nature’s Pest Management Services
Once information is available on key pests and their natural enemies, the biolovical strategies can be considered:. For example goldenrod and fennel can be planted to harbor aphids that serve as hosts for early-season predator species. Intercropping is the practice of growing two or more crops usually different families in the same area.
Try asking one of our Experts. Early research demonstrated that biological control bioolgical insect pests can be achieved if significant numbers of natural enemies are present at critical times during pest development.
More bioological is needed to understand the complex interactions among pests, natural enemies, and mixed crop habitats. This term is used because we are providing food and habitat for the top animals in the food chain, the predators and parasites. 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.
