By Dr. Rob Morrison Research recently appearing in the journal Biological Control may change how we view native predators of the brown marmorated stink bug (BMSB). BMSB is an invasive species that was accidentally introduced to the United States from Asia in Pennsylvania, and has since been detected in more than 40 U.S. states. It […]

Temperature Affects Stink Bugs More than Any Other Factors

Halyomorpha-halys-nymphs-wp

By Richard Levine Many things can affect the size and range of insect populations, including the climate, the availability of food sources, and the absence or presence of predators. But when it comes to certain stink bugs, researchers have found that temperature is the most important factor affecting regional distribution and abundance. By using complex […]

Natural Born Stink Bug Killer Found in Washington State

Trissolcus-japonicus23

Since 2007, the U.S. Department of Agriculture has been directing studies of a tiny Asian wasp called Trissolcus japonicus. These wasps are parasitoids of the brown marmorated stink bug (Halyomorpha halys), which has caused millions of dollars in damage to fruit orchards since it was discovered in the U.S. less than two decades ago. Researchers […]

Research on Stink Bug Damage to Sweet Corn May Help Growers Manage Them

stinkbug

Cooperative Extension agents and researchers at the University of Delaware are taking a closer look at how brown marmorated stink bugs (Halyomorpha halys) are causing damage to developing ears of sweet corn, the results of which could lead to better pest management strategies for growers throughout the state. Their findings were recently published in the […]

Stink Bugs’ Tree Host Preferences May Provide Management Clues

Halyomorpha-halys

By Kevin Fitzgerald Since its discovery in Pennsylvania in 1998, the brown marmorated stink bug (Halyomorpha halys), an invasive species native to eastern Asia, has swept into most U.S. states, parts of Canada, and several European countries. The creature feasts on a wide variety of fruits, vegetables, soybeans, and ornamental plants. New research published in […]

Stink Bugs as Biocontrol Agents Against … Stink Bugs

Podisus-maculiventris-BMSB

By Chris Patrick Imagine combating stink bugs with … stink bugs. Halyomorpha halys, the brown marmorated stink bug (BMSB), is a notorious, non-native agricultural pest — an indiscriminate destroyer of fruits, vegetables, and other farm crops. Managing this pest with a biological control agent (a living organism) is especially important for organic farmers whose regulations […]

Brown Marmorated Stink Bug Biology and Management Options Discussed in Open-access Journal Article

The brown marmorated stink bug (Halyomorpha halys) is an invasive, herbivorous insect species that was accidentally introduced to the United States from Asia. First discovered in Allentown, Pennsylvania in 1996, it has since been found in at least 40 states in the U.S. as well as Canada, Switzerland, France, Germany, Italy, and Lichtenstein. In North […]

Photo Slices Provide Detailed Images of Tiny Wasps for Biocontrol Efforts

Using specialized digital photography methods, USDA scientists are producing high-resolution images of members of the wasp superfamily Platygastroidea. According to Elijah Talamas, a postdoctoral scientist with the USDA’s Agricultural Research Service (ARS), the photographic process begins with positioning a wasp specimen under a specialized camera with a single-column lens attached to a vertical joist, and […]

Scientists Decipher Stink Bug Aggregation Pheromone

Ever since the brown marmorated stink bug (Halyomorpha halys) was first discovered in Allentown, Pennsylvania in the late 1990s, it has spread to more than 40 states and parts of Canada. It has devastated orchards, crops, and fields, and has become a terrible nuisance in gardens, backyards, and homes. It has an appetite for as […]

Entomologists Use Dogs to Hunt Down Stink Bugs

Last year at Entomology 2013, the 60th Annual Meeting of the Entomological Society of America, scientists from the U.S. Department of Agriculture gave a presentation called “Exploring Overwintering Ecology of Brown Marmorated Stink Bug Using Detector Dogs.” Now they have published an article about this topic in the journal PLOS ONE. The brown marmorated stink […]
