Centipedes should be considered beneficial because they are exclusively predatory. They eat a wide variety of smaller invertebrates, including insects. However, centipedes may be considered a nuisance to homeowners when they are found inside.

Camelina sativa (L.) Crantz (camelina) is an oilseed producing plant in the Family Brassicaceae (Cruciferae) originating from the Mediterranean to Central Asia. There is increasing interest in converting waste cooking oil and oil produced from oilseed crops, such as camelina, into biofuels in order to decrease dependence on petroleum products for fuel sources. The interest for growing oilseed crops in Utah is growing as well. Camelina sativa is a low input oilseed-producing crop adapted to climates similar to central Utah. Central Utah is also home to the Utah commercial turkey industry.
