    Samurai Wasp Hunts Brown Marmorated Stink Bug in Utah 

    Samurai wasp

    Brown marmorated stink bug (BMSB) is an invasive insect that first invaded Utah in 2012. It has since caused urban nuisance problems and poses a serious threat to various commercial fruit and vegetable crops. In June 2019, the samurai wasp was discovered in Salt Lake City. This exotic parasitoid wasp is the most promising agent for biological control of BMSB and is uniquely evolved to lay its eggs inside of BMSB eggs. This handout describes how to determine if BMSB eggs have been parasitized by the samurai wasp.

    Parasitoids of Brown Marmorated Stink Bug 

    Samurai wasp

    The brown marmorated stink bug (BMSB) is an invasive pest that damages fruit, vegetable, and nut crops in the U.S. Parasitoid wasps that sting and kill BMSB eggs are the most promising biological control method. This fact sheet describes some of the parasitoid wasps that have been found in Utah, as well as Trissolcus japonicus, a very effective parasitoid wasp that is native to BMSB’s home range and was recently detected in Utah in June 2019.

    Velvet Longhorned Beetle

    Velvet Longhorned Beetle

    A fact sheet containing many facts about Velvet Longhorned Beetle (VLB). VLB is an invasive wood-boring beetle that is native to Asia and Russia. It was first detected in Utah in 2010. VLB will attack living and dying trees, as well as green and dried wood; it can infest apple, cherry, mulberry, peach, and a number of deciduous and conifer tree species. Fruit yield, tree longevity, and wood marketability can all be negativly impacted by VLB. Download

    Spotted Lanternfly

    Spotted Lanternfly

    A fact sheet containing many facts about Spotted Lanternfly (SLF). SLF is a new invasive pest from China. It was first detected in the U.S. in Pennsylvania in 2014. SLF attacks more than 70 host plants, including grapes, fruit trees, hops, and hardwood ornamental trees. Extensive feeding results in weeping wounds, which combined with SLF's sugary excrement, can promote the growth of sooty mold, a gray-black fungus, that can impact plant vigor and crop yield. Download

    European Cherry Fruit Fly

    European Cherry Fruit Fly

    A fact sheet containing many facts about European Cherry Fruit Fly (ECFF). ECFF is a new invasive cherry-infesting pest from Europe. It was first detected in North America in Ontario in 2016, and first detected in the U.S. in New York in 2017. Larvae are the damaging life stage; they feed exclusively within fruits, causing them to rot and fall off the tree. In Europe, heavy infestations have resulted in 100% fruit loss. Since adults fly only short distances, spread occurs primarily through movement of infested fruit. Download

    Brown Marmorated Stink Bug

    Brown Marmorated Stink Bug

    A fact sheet that focuses on the monitoring and management of Brown Marmorated Stink Bug (BMSB) in fruit and vegetable crops in Utah. BMSB was accidentally introduced into the eastern U.S. from Asia in the late 1990s. It was first detected in Utah in 2012 and since 2017 has caused damage to fruits in vegetables in some Northern Utah counties. Download

    Small Hive Beetle 

    Small Hive Beetle

    A fact sheet containing many facts about Small Hive Beetle (SHB). SHB is an exotic pest of honey and bumble bee colonies that is native to Africa. SHB feeds on pollen and honey, kills bee brood and workers, and causes honey to discolor and ferment. This pest is now found throughout much of the U.S. with highest infestations occurring in the Southeast. It was first detected in Utah in 2016 and is now confirmed in Washington and Davis counties. Infestations can be prevented by early detection, using good husbandry techniques, maintaining a high ratio of bees to comb, and keeping hives in partial to full sun. Chemical control options for SHB are limited due to toxicity to bees. Download

    Balsam Woolly Adelgid

    A fact sheet containing many facts about Balsam Woolly Adelgid (BWA). BWA is a tiny sucking insect that was introduced to North America from Europe. In the U.S., it is a serious pest of true firs in forests, landscapes, and in seed and Christmas tree production. In some areas of North America, BWA has completely removed true firs from forest stands. In Utah, subalpine fir is a highly susceptible host tree; white fir is also a host but is more tolerant.Download

    Emerald Ash Borer

    Emerald Ash Borer

    A fact sheet containing many beneficial facts about Emerald Ash Borer. New infestations are difficult to detect and damage may not be obvious for years. They infest tree crowns first but EAB adults leave behind distinctive D-shaped exit holes (1/8 inch wide) when they emerge from trees in the spring, and when the larvae chew through the bark, they create serpentine shaped, excrement-filled channels that may be seen by peeling bark away from the tree.Download

    Spotted Wing Drosophila

    Spotted Wing on Fruit

    This fact sheet has general information concerning Spotted Wing Drosophila (SWD). SWD has been detected in many counties in northern Utah, and can be controlled using insecticides common in fruit integrated pest management plants. If SWD is caught in monitoring traps, insecticide applications must be used during the unripe fruit stage to prevent damage.
