The primary method to control the spread of the HLB-pathogen, carried by the Asian citrus psyllid (ACP), has been through frequent insecticide sprays. A more effective approach could be the use of chemical lures to trap and eliminate these insects. However, ACPs are not attracted to pheromones, the usual secreted chemicals used for such purposes. Instead, they respond to complex volatile organic compounds (VOCs) that resemble citrus plant smells. The challenge is that ACPs react differently to even slight variations in these compounds’ concentrations. Simple VOC mixes are not very effective, and managing the dispersion of multiple compounds is technically demanding. This research aims to refine the use of complex VOCs as ACP attractants, utilizing innovative materials for their dispersion.

Exploring the Invisible Chemical Landscape of Our Homes
Did you know that our indoor spaces are bustling with an invisible chemical world? A recent study by Alexander Aksenov, a UConn’s Department of Chemistry researcher, delves into this fascinating realm. Collaborating with experts from the University of California, San Diego, Colorado State University, and the University of Colorado, Aksenov’s team has uncovered surprising insights into our homes’ molecular and microbial environment.
Canine detection and identification of SARS-CoV-2
The research article “Sniffing out safety: canine detection and identification of SARS-CoV-2 infection from armpit sweat” focuses on the use of detection dogs to identify SARS-CoV-2 infection through armpit sweat odor. The study collected sweat samples from positive and negative human patients, confirmed by qPCR tests, across multiple hospitals and organizations in Belgium. These samples were then used to train six dogs under controlled conditions for 2-3 months.
