Want a Wall-Walking Robot? Look to the Honey Bees
Research into the pattern of walking in honey bees as they scale a vertical surface shows they switch their style of gait when turning compared to when walking in a straight line. The insights into bees' biomechanics may have future applications in robotics.
Cannibalism in Mosquito Larvae Confounds Egg Counts
New research shows that late-stage Anopheles gambiae larvae will eat eggs and first-instar larvae of their own species, calling into question the common view that females of the mosquito species avoid laying eggs in water where other larvae are already present.
Researchers Propose Standardized Naming of Lab-Reared Insect Stocks
Entomologists at the Great Lakes Forestry Centre in Canada have crafted a standardized naming convention for their laboratory insect stocks, and they suggest other similar facilities could adopt the naming format, as well.
Testing Shows Dry, Red Sticky Traps Improve Spotted-Wing Drosophila Monitoring
A new study finds spotted-wing drosophila prefer red, glue-covered monitoring traps made of plastic rectangles or spheres compared to the most commonly used clear deli-cup traps. The findings will advance the pursuit of more efficient and effective monitoring techniques for the pest.
Team Develops New Protocol for Embedding Insects in Resin
Insect and arthropod specimens set in clear resin are a valuable tool for teaching entomology both in the classroom and in public outreach. A team at Texas A&M University has developed an efficient, cost-effective process for resin casting and shares the instructions with the entomological community.
Bodycams Can Make for Better Agricultural Pest Management, Too
In a new study at the University of Arizona, researchers used body-mounted cameras to evaluate the efficiency of two insect pest sampling techniques—a sweepnet and a vacuum—in a cotton field. The perspective offered new insights into how such methods can be evaluated and could help growers and integrated pest management professionals further fine-tune their sampling techniques.
In Tick Management, Species Matters
One key factor plays a role in how well any particular tick-management method might work: Which tick species is it best suited for? A new guide in the Journal of Integrated Pest Management reviews research on tick management tools and their effectiveness on three tick species: the blacklegged tick, the lone star tick, and the American dog tick.
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.
Oregon Researchers Find a Native Wasp With a Taste for Stink Bugs
A recent study in Oregon details the predatory habits of the wasp Astata unicolor—its preferred prey is the invasive brown marmorated stink bug—and notes its potential as a native natural enemy of the invasive pest.
Invasive Tick Persists in New Jersey
Officials in New Jersey report that the invasive tick Haemaphysalis longicornis has successfully overwintered and was found once again on a rural property in mid-April 2018, after an infestation was reported there in 2017, the first such appearance of the species within North American borders.
Eastern Larch Beetle Outbreak Just Keeps Going When Winter’s Not So Cold
The current outbreak of eastern larch beetle in northern Minnesota is going into its 18th year, and researchers have found that at least some eastern larch beetles are able to reach maturity without requiring an overwintering period. In short, warmer winters mean eastern larch beetle is killing trees faster than it can be managed.
Mites Emerge as Key Vector in Encephalitis Outbreaks in India
Larval mites, known as "chiggers," from the family Trombiculidae are vectors of the bacteria that causes scrub typhus. The infection has been implicated as a common cause of acute encephalitis syndrome in India, where public health professionals are looking to better understand the variety of mite species present on rodents and their rates of infection.
Beyond the Honey Bee: How Pesticides Affect Solitary, Cavity-Nesting Bees
Solitary bees face different—and less well-understood—challenges from pesticide exposure than their colony-dwelling honey bee cousins. A pair of entomologists encourage colleagues to dedicate more research to these important pollinators.
Gut Microbes Can Help Insects Beat Pesticides
Insects have evolved a variety of mechanisms to try to overcome the effects of insecticides—including, in some cases, help from the bacteria and other microbes living in insects' guts. A growing number of studies indicate a link between symbiotic microbes and insecticide resistance in a diverse range of insects.
A Better Picture of Head-Lice Transmission, Aided by Math and a Fine-Toothed Comb
Researchers in Argentina compared mathematical models of head lice transmission with analysis of infestations in school children and found that head lice infestations across a classroom likely require at least one severely infested child serving as a "superspreader."
Landscape Terrain Provides New Angle for Measuring Tick Abundance
A study of lone star ticks in the forested Missouri Ozarks found that nymphs and adults were more abundant in valleys and on north-facing hills than in other areas. Meanwhile, nymphs appeared less often in the areas of greater temperature variability, while adults were less prevalent with increased elevation.
