Method for generating optimal attractive scents for Asian Citrus Psyllid (ACP) biocontrol

Key Achievements So Far:

The research team, led by Stelinski, has developed an attract-and-kill (AK) trap that leverages ACP sensory responses. This trap, optimized in greenhouse and simulated field conditions, employs multiple sensory cues, including visual and UV colors, chemic

l attractants, and toxicants. A significant innovation is the use of a novel volatile-release device incorporating graphene. This device precisely controls the release of compounds, mimicking complex citrus scents, through short current pulses in graphene, which acts as an adsorber.

Project Team:

The project involves Alexander Aksenov, Douglas Adamson, Ali Bazzi from the University of Connecticut, and Lukasz Stelinski from the University of Florida.

Challenges and Opportunities:

Currently, in the initial stages of a two-year project, the team has optimized the manufacturing process for the graphene composite, ensuring consistent properties. They have also characterized the release of individual VOCs from graphene. A beta version of the device is being assembled for live insect testing. A potential challenge is the deployment of sufficient devices in crop areas to effectively manage ACP populations. However, the relatively low material costs offer the potential for economical large-scale production.

This research represents a significant step forward in developing more effective, environmentally friendly methods to control ACP populations and combat the spread of the HLB-pathogen in citrus crops.
