Farmscaping PrinciplesII. Increase Plant Structural Diversity
Think Ahead - encourage the right beneficial insects to be there when needed them to attack the pests. Timing of ladybugs/Trichogramma wasps to attack the eggs of caterpillars.
Work Backwards from the PEST to the Beneficials to the plants/requisites that attract the beneficials.
Farmscaping Principles II. Increase Plant Structural Diversity
Fennel is great for attracting parasitic wasps, syrphid flies, and ladybugs. So one plant can bring in a guild of beneficials.
FS Principles- II. Increase Plant Structural Diversity: Overwintering
It turns out that many beneficials make cocoons and hibernate in or very near the plants where they find their hosts. Recent research has shown that yarrow and comfrey are also excellent overwintering plants for parasitic wasps.
FS Principles - III. Increase time plant resources are available
1 to 5% of crop area should be planted in farmscaping plants- “lots of clumps of food plants spread out over an area is much better than one big clump”. Or, incorporate farmscaping into borders, ditches, and fencerows.
FS Principles: Have something blooming all the time
Flowers are prime food & mating sites for wasps. Important to have a well fed, mated female beneficial! Green House – use to Jump-start garden areas.
FS Principles: Nectar!
Nectar – liquid sugar food + vitamins for beneficials. Nectar is critical for optimum performance of many beneficials. Many beneficials will lay over 3-10 fold more eggs if properly fed.
FS Principles: Extra-Floral Nectaries
Nectar glands that are not associated with flowers. Peonies, Sweet potatoes, bachelor buttons, kenafe, all have extrafloral nectaries. Parasitic insects use these extrafloral nectaries as important food sources.
FS Principles: Pollen
Is an alternative form of protein. Once again, many plants in the wild carrot family can provide pollen. Another good pollen producer is the corn plant. Syrphid flies need pollen to lay eggs.
FS Principles: IV. Decrease Distance beneficials travel

FS Principles: V. Take Advantage of Insect/Plant Behavior: Entrainment
Entomologists have discovered that insects (especially parasitic wasps and flies) can perform associative learning, so if you get insects (especially young ones) happy in their environment, they will “tune in” to a particular pest and food plants.
FS Principles: Drought/Stress
These systems can also fail! In drought years insects from all over will come to your area and can overwhelm a system. Be ready with backups additional insects, ladybugs/lacewings, Bt, soaps, diatomaceous earth.
FS Principles: Hold Yer Fire!
““I didn’t know what is I didn’t know what is was….. So I killed it.”was….. So I killed it.”
Remember you need some pests around in order to feed your beneficials. If you have to spray, use materials that are biorationals (like Bt) and won’t kill your beneficials. Realize that broad-spectrum pesticides kill everything and you are resetting your beneficial clock back to zero.
FS Principles: Lastly -Encourage Diversity!
Remember that insects are part of the web of life in your garden or farm. The beneficial insect complex is not only composed of parasitic wasps and flies, predatory beetles, lacewing larvae, ladybugs and so on, but ALSO the pollinators, antagonists/competitors that occupy and compete for space and food with potential pests, and finally the saprophytes and decomposing insects that help complete the food cycle back to the soil so the cycle can start again.
