Poplar Borer, Marion Murray, Ryan Davis Aug 2023

Poplar Borer, Marion Murray, Ryan Davis

All Current Publications

The poplar borer is the most commonly submitted wood borer found in aspens and other poplars in Utah. While large trees are seldom killed by this pest, it can cause the decline of trees, weakening of branches or the bole (which promotes wind breakage), and allows the introduction of pathogens. This fact sheet describes poplar borer life cycle, damage, and control.

Emerald Ash Borer (Agrilus Planipennis [Fairmaire]), Emily A. Parent, Lori R. Spears, Ryan S. Davis, Ricardo Ramirez

All Current Publications

Emerald ash borer (Order: Coleoptera: Family Buprestidae) (EAB) is an invasive wood-boring insect that infects the true ash species (Fraxinus spp.). EAB is native to parts of China, Korea, Japan, Taiwan, and small areas of Russia and Mongolia. EAB was first discovered in North America in June 2002 near Detroit, Michigan, and Windsor, Ontario, Canada, and is thought to have arrived to North America via infested wood packing material. EAB is generally established in an area for several years before it is detected and can spread over large areas through active flight and human-mediated dispersal.

Codling Moth In Utah Orchards, Marion Murray, Diane G. Alston Jan 2020

Codling Moth In Utah Orchards, Marion Murray, Diane G. Alston

All Current Publications

Codling moth (Order Lepidoptera, Family Tortricidae) is the most serious pest of apple and pear worldwide. In most commercial fruit producing regions and home yards in Utah, fruit must be protected to harvest a crop. Insecticides are the main control tactic. There are new insecticides available, many of which are less toxic to humans and beneficial insects and mites than earlier insecticides. For commercial orchards with more than 10 acres of contiguous apple and pear plantings, pheromone-based mating disruption can greatly reduce codling moth populations to allow reduced insecticide use.


Codling Moth Mating Disruption, Marion Murray, Diane G. Alston Jan 2020

Codling Moth Mating Disruption, Marion Murray, Diane G. Alston

All Current Publications

Mating disruption became commercially available in the early 1990s, and was adopted by many Utah growers about a decade later. Use of this pest management technology can be daunting due to high up-front costs and monitoring requirements; however, after two to three seasons of use, the cost of mating disruption is the same or even less than conventional pest management.


Common Crane Fly In Turf, Ricardo Ramirez, Kelly Kopp Jun 2015

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.


Bark Beetles, Ryan S. Davis, Darren Mcavoy Jul 2012

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.

Cat-Facing Insects, Diane Alston, Michael Reding, Marion Murray Oct 2010

Cat-Facing Insects, Diane Alston, Michael Reding, Marion Murray

All Current Publications

There are a number of insects with the piercing-sucking feeding habit that can cause deformity and catfacing type injury to pome and stone fruits, including lygus bug, stink bug, and boxelder bug. Cat-facing injury is caused by puncture feeding in flower buds and fruit. The result is unsightly dimpling, deformity, and scarring of fruit. The name “cat facing” comes from the distorted fruit shape that resembles the puckered cheeks of a cat. In addition to the insects discussed in this section, some aphids and the campylomma bug can inflict similar injury.


Chinch Bugs, Kelly Kopp, Ryan S. Davis, Ricardo A. Ramirez Sep 2010

Chinch Bugs, Kelly Kopp, Ryan S. Davis, Ricardo A. Ramirez

All Current Publications

Chinch bugs are “true bugs”. In Utah, the common chinch bug [Blissus leucopterus leucopterus (Say)], and western chinch bug (Blissus occiduus) may feed on turfgrass, especially under conditions of severe heat and drought. Coupled with under-irrigation, direct sunlight, and thick thatch, chinch bug numbers can soar from mid-summer to early fall.


Boxelder Bug, Erin W. Hodgson, Alan H. Roe Jun 2010

Boxelder Bug, Erin W. Hodgson, Alan H. Roe

All Current Publications

Boxelder bugs are a common nuisance insect to many homeowners. Although boxelder bugs are active throughout the summer, many people don’t notice them until they start “sunning” themselves on structures, particularly the southern-facing walls. As temperatures start to decrease in the late summer and fall, large numbers of adults will move from plants and congregate on heated buildings.

Cockroaches, Ryan S. Davis Jan 2010

Cockroaches, Ryan S. Davis

All Current Publications

Cockroaches are one of the most difficult structural pests to eradicate because of their ability to hide, rapid reproduction, and resistance to and avoidance of many commonly used insecticide sprays and baits. Using an integrated pest management (IPM) program can greatly increase the possibility of successful control. There are 4 cockroach species that commonly infest structures in Utah, each with a specific biology; identify invading cockroaches before you develop an IPM plan. Proper identification of any pest will allow you to understand its biology, and use it against itself!

Centipedes, Erin W. Hodgson, Paul Bingham, Alan H. Roe

All Current Publications

Centipedes are long, slender arthropods in the class Chilopoda. Centipede means “hundred feet” because they appear to have many legs. Insects, millipedes and arachnids are close relatives. 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.
