Native Predators May Be Having a Larger Impact than Expected on Invasive Stink Bug


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


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 […]

Stink Bugs as Biocontrol Agents Against … Stink Bugs


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 […]

Biological Control to Manage Stink Bugs


“Biological control” is a way of managing pests by using natural predators. In this blog, we’ve written about how some wasps parasitize caterpillars by laying eggs inside them, and how scientists in California are using wasps to control insects attacking citrus trees. We’ve also written about scientists using insects to control invasive plant species, and […]

Government Shutdown is Bugging Entomologists


The recent government shutdown due to a stalemate in Congress over funding for 2014 is impacting research on insects which will affect the lives of many Americans, according to the Entomological Society of America (ESA). In addition to the closing of government agencies such as the Department of Agriculture, the National Institutes of Health, and […]

Stink Bugs Invading Homes Before Winter


The brown marmorated stink bug (BMSB), an invasive insect from Asia, was first collected in the U.S. in Allentown, PA in 1998. Since then it has spread to more than 40 states. The BMSB damages fruits and vegetables and costs farmers millions of dollars each year. They are also a nuisance for home owners in […]

What You Really Need to Know about the 2013 Cicada Invasion


By Tracy Leskey Want to see people’s eyebrows raise? Tell them you are en entomologist, aka someone who studies bugs, in the summer of the “cicada invasion.” According to the Peterson’s A Field Guide to the Insects, “Entomologists fall into two categories: those who find insects endlessly fascinating and those who would get rid of […]
