Invasive plants boost mosquitoes in low-income areas of Baltimore and DC
Peer-Reviewed Publication
This October, things are getting a little creepy and crawly. We're shining a light on the fascinating world of arthropods, from insects and spiders to scorpions, centipedes and more, and exploring the latest research on the creatures that crawl, creep and fly all around us.

In many urban areas, low-income neighborhoods have more mosquitoes, making residents more vulnerable to mosquito-borne diseases. A new study co-authored by scientists at Cary Institute of Ecosystem Studies found that invasive, nonnative plants, which tend to be more common in low-income areas, boosted mosquito populations in Baltimore, MD, and Washington, DC. The results, published in the Journal of Medical Entomology, suggest that cities and their residents could reduce mosquito infestations by planting native tree species.
A research team has uncovered the chemical basis behind the distinctive honey aroma and mellow sweetness of leafhopper-pierced tea, showing that insect piercing reshapes both volatile and non-volatile metabolites across green, yellow, white, and oolong teas.
Hormones regulate development and reproduction not only in humans, but in all animals, including pests that threaten livestock and crops. Invasive insect pests cost U.S. agriculture billions of dollars each year, threatening crops and challenging the farming industry. Some mimics of hormones are used to control insect pests, yet scientists still have much to learn about how they work or how insects develop resistance to them.
An international team of scientists has uncovered new information about the natural enemies of the weevil beetle Lixus subtilis, a notorious agricultural pest. Published in the journal ZooKeys, the study reveals the discovery of an entirely new species of hyperparasitoid wasp in China, named after the famous writer Ernest Hemingway, alongside the first regional record of a wasp species that parasitises the weevil pest. Together, these findings offer critical insights into complex agricultural food chains and provide a foundational step toward developing better biological pest control methods.
Insects have evolved remarkable ways to avoid predators, with plant mimicry among the most effective. Many living and extinct insects resemble twigs, bark, mosses, lichens or leaves, allowing them to blend seamlessly into their surroundings.
Inspired by insect compound eyes, Prof. Ji Chen’s team from Southeast University proposes a bioinspired motion detector based on planar metalens arrays. It realizes an ultra-wide 135° field of view and achieves high-precision perception of moving targets’ velocity and direction. The design effectively detects tiny and slow-moving objects in complex backgrounds and enables intelligent motion trajectory prediction. Featuring high integration and lightweight structure, it provides solid technical support for autonomous perception, industrial early warning and unmanned intelligent systems.
