Flowers or extra-floral nectaries provide nectar. This is an eOrganic article and was reviewed for compliance with National Organic Program regulations by members of the eOrganic community. This snhance some information-gathering and management skill on the part of the grower, but this investment can result in the following benefits:.
Strip cropping is a derivation of intercropping and is the practice of growing ti or more crops in alternating strips across a field. 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.
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. 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.
Successful use of trap crops is challenging. Arthropod pest management in organic crops. Farmscaping is a whole-farm, ecological approach to increase and manage biodiversity with the goal of increasing eenhance presence of beneficial organisms.

These plants have small, open flowers that are accessible to the tiny mouthparts of small, parasitic wasps. Rather, it is an ecological approach or tool that can be combined with other pest management strategies as part of an integrated organic pest management program.
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.
Nectar is a source of liquid sugar energy and vitamins for beneficials, and is critical for optimum performance. Likewise, natural enemies require adequate supplies of nectar, pollen and plant-feeding insects and other arthropods as food to sustain and increase their populations.
The supplemental nectar provided by extrafloral nectaries is important, especially during the early season or periods of drought when few plants are in bloom.
Annual Review of Entomology. Wild parsnip left and Figure 7. Geoff Zehnder, Clemson University.
Pest management systems guide [Online]. 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.
Intercropping, companion planting and trap cropping are three examples:.
However, creating a farmscape of flowering plants picked at random may favor pest populations over beneficial organisms. Pests find it easier to locate host plants when grown in a monoculture versus a mixed planting. There are many different approaches and strategies in farmscaping.

Alternative hosts for beneficial insect prey. The trap crop can be a different plant species, a different variety, or just a different growth stage of the same farmscaoing, as long as it is more attractive to the pests when they are present.
Farmscaping methods include the use of insectary plants, hedgerows, cover crops, and water reservoirs to attract and contrkl populations of beneficial organisms such as insects, spiders, amphibians, reptiles, bats, and birds that parasitize or prey upon insect pests.
Sampling of crop plants should be done at least weekly. Insect sampling guidelines are available online. Interplantings of non-host crops may also act as a food source or habitat for beneficial organisms. An easy way to add Umbeliferae to the farmscape is to buy carrots or parsnips at the market with the tops on and plant them in the farmscape. Livestock producers will tell you that their animals are healthier and reproduce congrol readily when provided an adequate and nutritious diet.
Parasitic and predatory insects use extrafloral nectaries as food sources and mating sites. Try asking one of our Experts. Observation and experience are the most valuable tools in this regard.
