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.

Integrated Pest And Pollinator Management, Ann Mull, Lori R. Spears, Marion Murray, Ricardo Ramirez
All Current Publications
An inextricable link exists between humans and pollinators, with benefits that include ecosystem health and function and human food security. Bees, butterflies, moths, wasps, flies, and beetles are responsible for most the world's pollination services. Considering the mounting scientific evidence denoting global pollinator declines, there is a critical need to prioritize pollinators and the essential services they provide. This fact sheet provides information about integrated pest and pollinator management (IPPM), which goes beyond integrated pest management (IPM) to include proactive, preventive measures that consider pollinators as well as pests in horticulture management.

Spongy Moth (Lymantria Dispar Dispar Linnaeus), Ann Mull, Lori R. Spears
Spongy Moth (Lymantria Dispar Dispar Linnaeus), Ann Mull, Lori R. Spears
All Current Publications
Spongy moths (Lepidoptera: Erebidae) are invasive leaf-eating (defoliating) pests that threaten trees and shrubs in urban, suburban, and rural landscapes. The spongy moth was accidentally introduced to the U.S. in 1869 by an amateur French entomologist in Massachusetts who sought to establish a hardier American silkworm industry. These moths now commonly occur in the northeastern U.S. and are also found in parts of Illinois, Indiana, Michigan, Minnesota, North Carolina, Ohio, Virginia, West Virginia, Wisconsin, California, Oregon, and Washington. In Utah, according to the Utah Department of Agriculture and Food (2021), the spongy moth is anticipated to survive and multiply rapidly …
Billbugs In Turfgrass (Sphenophorus Spp.), Desiree Wickwar, Ricardo Ramirez
Billbugs In Turfgrass (Sphenophorus Spp.), Desiree Wickwar, Ricardo Ramirez
All Current Publications
Billbugs are weevils, a type of beetle, in the genus Sphenophorus. At least 10 billbug species are known pests of turfgrass and can be found in both warm and cool season turfgrasses throughout the United States. Though billbug adults do feed on the leaves of turfgrasses, it is the larvae that cause visible damage. Larvae feed within the stems and on roots of grasses, leading to the development of yellow or brown patches, with the potential to escalate into large patches of dead turfgrass. Billbug management in turfgrass presents a number of unique challenges, but early monitoring and informed integration …
Factors Contributing To Bee Decline, Ann Mull, Jaydee Gunnell, Sheriden M. Hansen, Ricardo Ramirez, Andree' Walker Bravo, Cody Zesiger, Lori R. Spears
Factors Contributing To Bee Decline, Ann Mull, Jaydee Gunnell, Sheriden M. Hansen, Ricardo Ramirez, Andree' Walker Bravo, Cody Zesiger, Lori R. Spears
All Current Publications
Bees provide an important ecosystem service by contributing to the pollination of crop and wild plant species. Many factors have been attributed to bee declines, including habitat loss, improper apiary management, pesticide usage, climate change, pests and pathogens, competition among native and introduced bee species, poor nutrition, and other factors (Koh et al., 2016; Goulson et al., 2015; Graves et al., 2020; Soroye et al., 2020). Acting together, these factors intensify the pressure for survival beyond the adaptability of many species. This fact sheet reviews the factors contributing to decline in bee populations and what can be done to protect …

Sap Beetles, Nick Volesky, Zachery R. Schrumm, Kalen Taylor
All Current Publications
Sap beetles are typically considered a secondary pest of corn and overripe fruits and vegetables. They are broadly identified by their small and ovular bodies and club-shaped antennae. Adult sap beetles often feed on corn silk, pollen, and tassels. Larvae feed on kernels inside the husk. This fact sheet reviews how to identify sap beetles and their hosts and damage. It also provides ideas on how to monitor for sap beetles and outlines the options for managing them.

Lily Leaf Beetle, Ann Mull, Lori R. Spears
All Current Publications
The lily leaf beetle (LLB) (Coleoptera: Chrysomelidae) is an important pest from Eurasia that threatens native and cultivated true lilies (Lilium spp.) and fritillaries (Fritillaria spp.). It is also known as the red lily leaf beetle or scarlet lily beetle. LLB was first reported in North America in Montréal, Canada, in 1945 and in the U.S. in 1992 in Massachusetts, likely arriving via European shipments of lily bulbs. LLB has been detected in nine of the 10 Canadian provinces and 14 U.S. states, including the New England states, Pennsylvania, Wisconsin, Minnesota, and Washington (EDDMapS, 2021). Based on LLB’s native distribution …

In Utah high tunnel production, there are various caterpillar pests (larvae of moth and butterfly species) that cause economic damage to crops. Common caterpillar pest species found in Utah include hornworms, tomato fruit worms, imported cabbage worms, diamondback moths, cabbage loopers, armyworms, and cutworms. Various weed species growing inside or outside high tunnels can attract and harbor caterpillar pests. Managing caterpillar pests in high tunnels involves various mechanical, chemical, biological, and cultural control practices.

Prácticas De Jardinería Y Paisajismo Para Anidación De Abejas Nativas, James H. Cane, Celina Wille
All Current Publications
Utah es hogar de alrededor de 1,000 especies de abejas nativas identificadas, con varios cientos de especies viviendo en alguno de los valles y ábitats montañosos adyacentes. La urbanización causa daños a las abejas nativas, pero muchas especies pueden persistir con un poco de ayuda de jardineros y paisajistas. Al igual que las aves, las abejas tienen dos necesidades principales en la vida: alimento (para una abeja, polen y néctar) para alimentarse a sí mismas y a sus crías, y un lugar adecuado para anidar.

Hay una serie de insectos con el hábito alimenticio de perforar y succionar que pueden causar deformidad y lesiones del tipo cara de gato en los frutales de pepita y hueso, como la chinche ligus, la chinche hedionda y la chinche del boxelder. La lesión cara de gato es causada cuando la chinche se alimenta agujerando los botones florales y la fruta. El resultado son depresiones, deformidades y cicatrices desagradables en la fruta. El nombre “cara de gato” proviene de la forma distorsionada de la fruta que se asemeja a las mejillas fruncidas de un gato. Además de los insectos …

Las chinches son “chinches verdaderas”. En Utah, la chinche común [Blissus leucopterus leucopterus (Say)] y la chinche occidental (Blissus occiduus) pueden alimentarse del césped, especialmente en condiciones de calor intenso y sequía. La falta de riego, junto a la radiación directa y la acumulación de material vegetal muerto puede elevar el número de chinches desde mediados del verano hasta principios del otoño.

Blue Orchard Bee (Osmia Lignaria): Commercial Pollinator For Orchards, Theresa Pitts-Singer
All Current Publications
The most common mason bee in Utah is the blue orchard bee. Blue orchard bees collect pollen from a large variety of flowering plants but prefer fruit trees from the family Rosaceae. Recent concerns about honey bees, coupled with the blue orchard bee’s superior pollination of tree fruits, have increased interest in rearing blue orchard bees.
