Why Don’t We Study Bed Bugs?

Bed bugs have garnered a lot of attention over the past few years, including coverage from mainstream media outlets (e.g., a search of the New York Times website for “bed bugs” calls up 4,270 mentions over the past 12 months). But their high profile has not led to a commensurate increase in related research. Bed…

Using Ants to Map Patterns of Diversity

They account for more than 80 percent of Earth’s species, but insects merit little respect in either conservation or global diversity studies. NC State biology professor Rob Dunn and postdoc Michael Weiser, along with Benoit Guénard, a former NC State Ph.D. student who now works at the Okinawa Institute of Science and Technology, want to change that,…

Know Your Enemy: Cockroaches

Most people think cockroaches are disgusting. And if you’ve ever turned on a kitchen light, to find them skittering for dark corners, you probably agree (reference: my first apartment). But of the thousands of species out there, only a few can be considered pests. There are well over 4,000 described (i.e., named) species of cockroach…

Know Your Enemy: Termites

Termites are fascinating insects, and not just because they can turn your front porch into mush. For example, did you know that many researchers have concluded that termites are actually social cockroaches? Whether you group them under the order Blattodea or Isoptera (and entomologists do both), there are more than 2,500 species of termites globally,…

Ticks and Mosquitoes: What the Mild Winter Really Means

There has been a lot of discussion about how a mild winter, an early spring and a bumper crop of acorns might affect the number of mosquitoes and ticks we’ll see this spring and summer. Will there be more blood suckers out there? Will we be at higher risk of Lyme disease? Like many things…

Know Your Enemy: Fire Ants

No series on arthropod pests would be complete without fire ants. They are violent. They are deadly. And they’re seemingly out to conquer the world. I’m exaggerating on that last point, but not by much. There are over 20 fire ant species around the world, including at least four species that are native to the…

Know Your Enemy: Japanese Beetles

Last year I wrote a series of posts about critters we love to hate: mosquitoes, ticks, horseflies, black widows and carpenter bees. With the arrival of spring, I decided to pick up where I left off. First up: Japanese beetles or, as rose-growers call them, #@!*ing Japanese beetles. As the name suggests, Japanese beetles –…

What’s A Genotype? What’s A Phenotype? And Why Do I Care?

Genetics research is interesting stuff, and news stories about exciting new findings seem to crop up almost daily. But many people simply don’t have the vocabulary to understand what’s going on. “What is a genotype anyway?” you might ask. “What’s a phenotype? And why should I care?” Good questions! Let’s talk about this a little…

During the conference, I had the opportunity to lead a small group of attendees on a tour of the forensic anthropology labs at NC State. The folks on the tour really enjoyed it, so I…

Insects And Evolution

Editor’s Note: This is a guest post by post-doctoral researcher Michelle Trautwein, whose work at NC State focuses on entomology, genetics and evolution. Here she explains what we know about insect evolution – and why it matters. Our planet is swarming with insects. Literally. Six-legged creatures account for the majority of life on earth, by far…
