So, You Want to Study Termite Control? Step 1: Raise a Few Million Termites

Subterranean termite colonies can be as large as 1 million individuals with a foraging territory and underground galleries stretching up to 100 meters long. How does an entomologist study something that large? Here's a behind-the-scenes look at how researchers at the University of Florida have raised entire termite colonies from scratch and devised experimental setups that mimic large foraging and nesting areas while still fitting inside a lab.

For Good of the Colony, Sick Honey Bee Brood Sounds the Alarm

Honey bees detect and remove brood afflicted with parasites or pathogens. A new study shows that part of this "hygienic behavior" relies on chemical signals emitted by unhealthy brood, and brood coming from colonies bred to be more hygienic are more effective in signaling for their own removal.

Fruit DNA in Invasive Flies’ Guts Could Help Track Their Dispersal

A recent study at North Carolina State University shows that DNA analysis of spotted-wing drosophila (Drosophila suzukii) flies can detect whether they fed on strawberries as much as seven days prior. Researchers hope the proof of concept will lead to more accurate analysis of the invasive pest's dispersal in the field.

Study Shines a (Fluorescent) Light on Invasive Fruit Fly Trapping

To estimate the catch rate of traps for invasive spotted-wing drosophila fruit flies in tart cherry orchards, researchers at Michigan State University first marked thousands of flies with fluorescent dust and released them. Then they counted the recaptured flies under ultraviolet light.

Study Shows Rapid Evolution in Lab-Reared Insects

A wide variety of insects (such as mosquitoes, shown here) are raised in the laboratory. A new review of research on lab-reared insects shows that they evolve rapidly as they progress through generations raised in artificial environments.

Do Chestnut, Lemon, or Peppermint Scents Repel Spiders?

In a study on three commonly cited natural spider repellents, both chestnut and peppermint oil showed apparent repellent effects on two species of spider but not on a third. Meanwhile, lemon oil did not have a significant effect on any of the three species included in the study.

Domestic Sea Trade Aids Wood-Boring Beetles’ Range Expansion

A study by entomologists in Italy found that the abundance of bark- and wood-boring beetles outside their native range but still within the same country is correlated with levels of trade at nearby sea ports, suggesting domestic sea transportation plays a role in insects' intra-country range expansion.
