Lab in Transition

The UPPDL loses yet another excellent diagnostician. Julie Jenkins, our Plant Pathology Diagnostician, will no longer be with the lab, but instead will be enjoying time with her family. We wish her well. In the meantime, we are in the process of looking for a replacement.

Common and Native Flowering Plants Attractive to Native Bees and Beneficial Insects

Elevated concern for the loss of honeybee populations due to Colony Collapse Disorder and associated stresses caused by loss of habitat and other factors leave us to ponder how humans can improve the habitat and food resources for the numerous species of native bees and beneficial insects in Utah.

A major resource required by native pollinators and beneficial insects is an abundant and quality source of flower nectar and pollen. High quality nectar serves as an excellent carbohydrate source while pollen can provide supplemental protein when prey are scarce, and supports reproduction and development of progeny (e.g., native bees provision their young with pollen and sometimes nectar).

By planting common and native flowering plants that produce high quality nectar and pollen in urban landscapes and agricultural areas, populations of native bees and beneficial insects will be enhanced, which will in turn enhance crop production and reduce the need for chemicals to manage insect pests. The table below provides recommendations for plants attractive to native bees.

 Table of common native plants attractive to pollinators.

Family Genus Common Name
Apiaceae Tanacetum tansy
Asteraceae Achillea yarrow
Centaurea bachelor’s button, corn flower (use single-flowered varieties)
Chrysothamnus rabbitbrush
Gaillardia blanket flower (use single-flowered varieties)
Helianthus sunflower
Rudbeckia black-eyed susan
Solidago goldenrod
Tithonia Mexican sunflower
Berberidaceae Mahonia mahonia, Oregon-grape
Caprifoliaceae Symphoricarpos snowberry
Crassulaceae Sedum sedum, stonecrop
Cucurbitaceae Cucurbita squash, gourd, pumpkin
Ericaceae Vaccinium blueberry, cranberry, huckleberry (needs acidic soils)
Fabaceae Baptisia false indigo
Cercis redbud
Hedysarum sweetvetch
Lespedeza bush clover
Lupinus lupine
Grossulariaceae Ribes currant and gooseberry
Hydrophyllaceae Phacelia bluebells, scorpionweed
Lamiaceae Mentha mint
Nepeta catmint
Perovskia Russian sage, filigran
Lythraceae Cuphea false heather
Malvaceae Sphaeralcea globemallow
Rosaceae Chamaebatiaria fern bush

Picture of the Quarter 

This syrphid fly is a beneficial predator. Its larvae feed on aphids and other soft-bodied insects. Adults feed only on pollen, nectar, and honeydew. Adults are marked with yellow or white bands. They emerge from their overwintered pupae in spring and lay eggs on leaves and stems of plants infested with prey. Larvae feed for 7 to 10 days, then drop to the soil to pupate. There are 3 to 7 overlapping generations each year.

One syrphid fly larva can consume almost 400 aphids!
