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.

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.

Spiders are arachnids, a group that includes other 8-legged arthropods like ticks, mites, sun spiders, scorpions, and harvestmen (daddy longlegs).

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.

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.

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 …

Slugs and snails are rated by many gardeners as the worst garden pests. Considering their competition, this is a dubious honor. These pests are not insects but are mollusks that are more closely related to shellfish, such as mussels and clams.

Preventing Poisoning Of Pets When Using Slug And Snail Baits, Kerry A. Rood, Larry A. Sagers
All Current Publications
Slugs and snails are one of the most common garden pests in the State of Utah. Because they are so widespread and destructive, many different methods are used to keep the pests under control. Baits are frequently applied as a treatment, but using pesticides can create hazard for non-target wildlife and pets.

Elm Bark Beetles And Dutch Elm Disease, Ryan S. Davis
All Current Publications
Bark beetles (Family Curculionidae, Subfamily Scolytinae) are some of the most devastating insect pests in the world. Closely related to weevils, there are almost 500 species of bark beetles in North America alone, each with unique host plants, habits, and life cycles. It is crucial to accurately identify a suspect bark beetle before you consider treatment options.
Eriophyid Mites, Bud, Blister, Gall, And Rust Mites, Ryan S. Davis, Taun Beddes
Eriophyid Mites, Bud, Blister, Gall, And Rust Mites, Ryan S. Davis, Taun Beddes
All Current Publications
Eriophyid mites are translucent, cigar-shaped microscopic mites that cause deformities on many plants species. These mites are noticed when their feeding causes abnormalities of plant tissues such as erineum, galls, brooms, leaf curling, blisters, rusts, silvering, fruit rusetting, and deformed buds, catkins, fruits, etc. Fortunately, these mites rarely cause serious harm to plants, and control is seldom needed. In fact, eriophyid mites can serve as an alternative food source for predatory mites when their primary food source is absent.
