Common Crane Fly In Turf, Ricardo Ramirez, Kelly Kopp
Common Crane Fly In Turf, Ricardo Ramirez, Kelly Kopp
All Current Publications
Crane flies belong to one of the most specious families of flies. The adult flies, also known as “mosquito hawks”, are not giant mosquitoes and do not bite, and though the name suggests it, they do not feed on mosquitoes. In general, the larvae are associated with aquatic and semi-aquatic habitats. The majority of crane flies are not pests.

Flea Beetles On Vegetables, Bonnie Bunn, Diane Alston, Marion Murray
All Current Publications
Flea beetles are common and problematic in Utah. They are present in late spring and early summer on many vegetable crops and ornamental plants. Adult flea beetles are small, shiny insects that have enlarged hind legs, allowing them to jump great distances when disturbed.

Walnut Husk Fly, Diane Alston, Marion Murray, James Barnhill
All Current Publications
Walnut husk fly (Order Diptera, Family Tephritidae; Fig. 1) is the most common insect pest of walnuts in Utah. Husk fly larvae (maggots) tunnel in walnut husks, causing them to soften and decay, and stain the shell (Fig. 2). Damaged husks are difficult to remove. If husk fly infestation occurs early in kernel development, nuts may shrivel, darken, become moldy, and drop from the tree (Fig. 3).
Apple Maggot, Diane Alston, Marion Murray
Apple Maggot, Diane Alston, Marion Murray
All Current Publications
Apple maggot is not currently a pest of commercial orchards in Utah, but it is regulated as a quarantine insect in the state. If it becomes established in commercial fruit production areas, its presence can inflict substantial economic harm through loss of export markets. Infestations cause fruit damage, may increase insecticide use, and can result in subsequent disruption of integrated pest management programs.

Shothole borers (Fig. 1) are bark beetles that may attack stressed or injured trees. They have a wide host range, including all fruit trees grown in Utah, quince, loquat, serviceberry, wild cherry, chokecherry, mountain ash, hawthorn and elm. In Utah, apple, cherry, pear, and hawthorn are preferred hosts.

Squash Bug (Espanol), Diane Alston, James Barnhill
All Current Publications
Squash bug (Anasa tristis) is a “true bug” with piercingsucking mouthparts (Order Hemiptera) in the leaffooted bug family (Coreidae). It is common throughout the U.S. and found from Canada to Central America. Adults (Fig. 1) emit a foul odor when disturbed and may be called “stink bugs”; however, true stink bugs are in a different true bug family.
Gardening For Native Bees In Utah And Beyond, James H. Cane, Linda Kervin
Gardening For Native Bees In Utah And Beyond, James H. Cane, Linda Kervin
All Current Publications
Utah is home to more than 20 percent of the 4,000+ named species of wild bees that are native to North America. Except for bumblebees and some sweat bees, our native bees are solitary, not social, many with just one annual generation that coincides with bloom by their favorite floral hosts. In contrast, the familiar honeybee is highly social, has perennial colonies, and was brought to North America by settlers from Europe.

Spiders are arachnids, a group that includes other 8-legged arthropods like ticks, mites, sun spiders, scorpions, and harvestmen (daddy longlegs). There are approximately 621 species of spiders known to occur in Utah (Allred and Kaston, 1983). Spiders are beneficial predators and the majority of them are harmless to humans.

Bark Beetles, Ryan S. Davis, Darren Mcavoy
Bark Beetles, Ryan S. Davis, Darren Mcavoy
All Current Publications
Bark beetles are one of the most destructive forest pests in the world. They are different than the larger longhorned and roundheaded/metallic woodboring beetles commonly infesting the inner wood of trees. The largest bark beetle, the red turpentine beetle (Dendroctonus valens), reaches only 8.3 mm in length. Because of their tiny size, bark beetles are not effective tree killers as individuals.

Beneficial Predators: Predatory Mites, Ron Patterson, Ricardo Ramirez
All Current Publications
Predatory mites can provide natural pest control by eating unwanted pests. These beneficial mites are one way to maintain pest populations at non-damaging levels, known as biological control. By encouraging predatory mite populations, plants can be protected from excessive pest attack and damage.

Western Striped And Western Spotted Cucumber Beetles, Diane Alston, Dennis Worwood
All Current Publications
Cucumber beetles (Coleoptera: Chrysomelidae) are pests of cucurbits throughout the U.S. Western species of cucumber beetles will also feed on leaves of other vegetables (especially corn, tomato, potato, and bean) and soft fruits (especially apricot and peach) (Table 1). In Utah, watermelon and cantaloupe have been the main commercial crops attacked. In home gardens, zucchini, cucumber and cantaloupe have suffered the most damage.

Aspen, Important Pests Of Ornamental Spen, Fred A. Baker, Diane G. Alston, Claudia Nischwitz
All Current Publications
Aspens are one of the more popular forest trees in the Intermountain West. They add a brilliant yellow glow to the collage of fall colors. In an attempt to enjoy these beautiful trees around the home environment, many well-intentioned homeowners purchase or otherwise acquire aspens and transplant them into their landscapes. Unfortunately, aspens are not adapted to the environmental conditions of the valleys, and many problems develop.

Integrated pest management (IPM) is the practice of combining knowledge of the pest and host plant with multiple tactics for long-term, safe pest control. The goal of IPM is pesticide reduction by using cultural, mechanical, and biological controls before the last option, pesticides.

Bumble Flower Beetle, Taun Beddes, Ryan S. Davis
All Current Publications
The bumble flower beetle (BFB) is a common member of the Scarabaeidae (scarab) beetle family. Its common name originated because adult BFB’s often fly close to the ground and emit a loud buzzing sound similar to that of a bumble bee. Larvae (grubs) and adults are often found in or near fermenting and/or decomposing organic matter.
Corn Earworm, Diane G. Alston, Shawn Olsen, James Barnhill
Corn Earworm, Diane G. Alston, Shawn Olsen, James Barnhill
All Current Publications
In Utah, there are typically three generations of corn earworm (CEW) each year. The first generation of adults either come from overwintering pupae (southern and central Utah), or migrate into northern Utah. The adult moth is tannish brown with a 1 1/2 inch wingspan. The front wings are marked with a distinct dark spot in the center and darker bands near the outer margins. The hind wings are lighter tan, with a dark band along the outer margins. The male moths have green eyes. Moth flight occurs primarily on warm, overcast evenings. Moth populations can be monitored using pheromone or …
