Efficacy of Trelona® compressed termite bait on subterranean termite (Reticulitermes spp. and Amitermes sp.) colonies within a 1-acre grid in Texas

Subterranean termite activity within a 1-acre grid located in central Texas was evaluated using in ground Trelona® subterranean termite monitoring stations (no active ingredient). Stations were inspected and termites were collected from active stations from 5/2017 through 5/2021. Termite DNA samples were genetically analyzed by sequencing the COII gene for species ID. Samples (ca.10 individuals) of Reticulitermes spp. were genotyped at several microsatellite loci for colony identification. Presence and location of individual colonies were tracked over time. Trelona® Compressed Termite Bait Cartridges (with novaluron) were introduced into ½ of the stations in 9/2020. Termite activity and number of active colonies was dramatically reduced post Trelona bait installation. Results will be presented at the 2021 ESA annual meeting0
