Africanized Honey Bee, Erin W. Hodgson, Cory A. Stanley, Alan H. Roe, Danielle Downey
All Current Publications
African honey bees (Apis mellifera scutellata) are native to sub-Saharan Africa and were introduced in the Americas to improve honey production in the tropics. These African honey bees were accidentally released and began to interbreed with European honey bees (Apis mellifera ligustica), the most common subspecies used for pollination and honey production in the United States (Fig. 1). As a result, the hybrid offspring are called “Africanized” because of their shared characteristics. Africanized honey bees are about the same size, shape and color as European honey bees (Fig. 2), and a genetic analysis must be used to distinguish one from …

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.

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.

The Japanese beetle, Popillia japonica Newman, can be a highly destructive pest to ornamentals, trees, shrubs, turfgrass, and vegetables. First discovered in the eastern United States in 1916, the Japanese beetle has threatened agriculture and horticulture by slowly moving south and west. In 2006, a small population of adult Japanese beetles was detected in Orem, Utah.

Turfgrass Cultural Practices And Insect Pest Management, Diane Alston, Kelly Kopp
All Current Publications
There are a number of insects that can cause aesthetic and economic loss to turfgrass in Utah – in home lawns as well as in athletic fields and on recreational lands. Good turfgrass cultural practices are the primary way to prevent insect infestation and turfgrass damage.

Spider And Predatory Mites Sampling Form, Usu Extension
All Current Publications
This sampling method uses the presence-absence method. Rather than counting the number of mites, scouts simply need to determine whether mites occur or do not occur on the collected leaves.

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.
Control Of Iron Chlorosis, Rich Koenig, Michael R. Kuhns
Control Of Iron Chlorosis, Rich Koenig, Michael R. Kuhns
All Current Publications
Iron deficiency (iron chlorosis) affects many desirable landscape and crop plants grown in Utah. The primary symptom of iron deficiency is interveinal chlorosis, the development of a bright yellow leaf with a network of dark green veins. In severe cases, the entire leaf turns yellow or white and the outer edges may scorch and turn brown as the plant cells die.

Lilac-Ash Borer, Ryan S. Davis, Taun Beddes, Jay B. Karren
All Current Publications
The lilac-ash borer (Podosesia syringae), belongs to a group of insects known as the clear-winged moths. The wings of most sesiid moths in have at least partially transparent wings (devoid of the colored scales that coat most moth and butterfly wings).
Cockroaches, Ryan S. Davis
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!
