Flowering plants provide many of the food resources natural enemies need. Strip cropping is a derivation of intercropping and is the practice of growing two or more crops in alternating fo across a field. This requires some information-gathering and management skill on the part of the grower, but this investment can result in the following cnotrol. Trap crops were originally designed to be used in conventional systems where insecticides could be used to kill the pests in the trap crop.
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:.
Another good pollen producer is the corn plant.
Priority is given to preventative pest management strategies like farmscaping, followed by more direct measures if preventative strategies are not sufficient. Intercropping, companion planting and trap cropping are three examples:. The most successful farmscape systems have been developed and fine-tuned by farmers to fit their individual circumstances.
Consider the Area to be Farmscaped. In planning the farmscape it is important to identify specific plants, planting situations, and management practices that best support populations of beneficial organisms.
Interplantings of non-host crops may also act as a food source or habitat for beneficial organisms. View publishing information about this page. Arthropod pest management in organic crops. Ehance plants like mustards interplanted with market crops provide pollen and nectar to attract and maintain beneficial insects in the crop landscape. Parasitic and predatory insects use extrafloral nectaries as food sources and mating cotrol. This is a broad topic that refers to the addition of specific plants to enhance the growth and quality of nearby crops.
Farmscaping to Enhance Biological Control
garmscaping 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.
This term is used because we are providing food and habitat for the top animals in the food chain, the predators and parasites. Farmscaping to enhance biological control: 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. 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 aims to prevent damaging levels of pests from developing in bilogical crop ecosystem. Flowering medicinal plants like echinacea, fever few, and boneset also have multiple uses. 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.
Wild parsnip left and Figure 7. Alfalfa planted biologocal a trap crop in strawberries to control tarnished plant bug. Recent research has shown that the quality, not quantity, of the farmscape plantings is most important. Ecological engineering for pest management: Assassin bugs are generalist predators; although they feed on both pest and beneficial insects they are generally considered to be beneficial.
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, biologgical area and color were the most important factors in disrupting host location. Pollen is a source of protein and protein is critical for egg laying.
For fwrmscaping goldenrod and fennel can be planted to harbor aphids that serve as hosts for early-season predator species. Flowers or extra-floral nectaries provide nectar.

Peonies, sweet potato, bachelor button and lima bean are examples of plants with extrafloral nectaries located on various parts of the plant. Sampling of crop plants should be done at least weekly.
For ejhance, 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.
Both practices serve to increase biodiversity and make the habitat less suitable for pest development. 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.
Planting a diversity of flowering plants to enhance biological control has been referred to as “chocolate box ecology” because of the colorful floral display. Many pest populations can be managed by enhancing the contol and local abundance of the existing community of natural enemies through modification of the environment, a concept that has been enhane “conservation biological control. However, creating a farmscape of flowering plants picked at random may favor pest populations over beneficial organisms.
Annual Review of Entomology. Flowers that provide pollen. 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.
Follow this link to a sample budget for establishment and maintenance of beneficial insect habitat: Therefore, a flexible approach is needed to be able to adjust beneficial habitat according to weather conditions. More research is needed to understand the complex interactions among pests, natural enemies, and mixed crop habitats.
A trap crop is a crop that is planted to lure insect pests away from the cash crop. For example, fennel and colored yarrow varieties can be sold as cut flowers. Geoff Zehnder, Clemson University.
