Peach Twig Borer Mating Disruption
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
The Backyard Orchardist β Fruit Pests: Pear
Fire blight is caused by a bacterium called Erwinia amylovora. Pears are very susceptible to fire blight. Blossoms, terminal twigs, and sometimes entire limbs or trees are killed. Environmental conditions favoring infection are warm, rainy days during bloom
Leafrollers in Fruit Orchards (Lepidopters: Tortricidae)
Leafrollers are a type of caterpillar that may roll or tie leaves together to form a protective shelter. They feed on the leaves and fruits of host plants. This fact sheet describes them, the crop injury they cause, their orchard preferences, monitoring, treatment timing, and management
Western Tentiform Leafminer
Western tentiform leafminer populations can vary tremendously between years or even between generations within a single year. Increasing resistance to organophosphate insecticides and variable effectiveness of at least six parasitic wasp species that attack the leafminer can influence the population size
European Cherry Fruit Fly Rhagoletis cerasi (Linnaeus)
European cherry fruit fly (ECFF) is a new invasive cherry-infesting pest from Europe. It was first detected in the U.S. in New York in 2017. This fact sheet describes it and includes life history, plant hosts, damage symptoms, monitoring, and management
Western Tentiform Leafminer Phyllonorycter elmaella
Western tentiform leafminer populations can vary tremendously between years or even between generations within a single year. A large population in Utah\u27s commercial fruit districts hasn\u27t been observed since the early 2000s. Increasing resistance to organophosphate insecticides and variable effectiveness of at least six parasitic wasp species that attack the leafminer can influence the population size
