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 …

Getting Chemicals Into Trees Without Spraying, Michael R. Kuhns
Getting Chemicals Into Trees Without Spraying, Michael R. Kuhns
All Current Publications
Chemicals are applied to trees for many reasons. Insecticides repel or kill damaging insects, fungicides treat or prevent fungal diseases, nutrients and plant growth regulators affect growth, and herbicides kill trees or prevent sprouting after tree removal. Spraying is the most typical way to apply these chemicals. It is fast, uses readily available equipment, and is understood. The down side of spraying is that much of the chemical being applied is wasted, either to drift, run off, or because it can not be applied precisely to where it is needed in the tree. Also, in many cases the chemical is …

Predatory insects can provide natural pest control by eating unwanted pests. Insect predators are one factor that help maintain pest populations at non-damaging levels, an action known as biological control. By conserving predatory insect populations, plants can be protected from pest attack and excessive damage.

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.

The fall webworm, Hyphantria cunea, is a common defoliator of ornamental and fruit trees in Utah.

European Earwig (Forficula Auricularia), Diane G. Alston, Andrew Tebeau
All Current Publications
The European earwig (Order Dermaptera, which means “skin wings” to describe their leathery wings) (Fig. 1) is native to Europe, western Asia, and parts of Africa. The common name “earwig” comes from a myth that the insect would climb into the ears of humans and chew into the brain, but this is false. The European earwig was first introduced into Utah in the early 1900s. Establishment and population growth have been remarkably successful in northern Utah.
General Concepts Of Biological Control, Diane G. Alston
General Concepts Of Biological Control, Diane G. Alston
All Current Publications
“Balance of Nature.” Virtually all pest populations are affected by natural enemies to some extent. In many cases, natural enemies are the primary regulating force of the pest populations. Natural controls include effects of natural enemies (predators, parasites, pathogens), other biotic (living) factors such as food availability and competition, and abiotic (non-living) factors such as weather and soil
