The USGS conducted the experimental implementation of sampling MSP sites during wet year conditions. The project utilized a stratified sampling design and a protocol developed in 2014. A combination of GIS and field measured covariates were used to identify drivers that impact Argentine ant population dynamics. The project also included developing potential measures to make the site less or unsuitable for Argentine ants. The outcome of this study will inform management actions for experimental implementation.
Name: Assessing Presence of Argentine Ants Using the Bait Method
Description: This protocol is geared towards recruiting Argentine ants to bait locations. Preferences for timing of sampling are recommended for optimizing collection of Argentine ants. Results from this type of bait study will not provide an accurate measure of what native ants are present, as many ants will not be attracted to the bait, may not be active during the baiting period, or will be competitively excluded once dominance over the bait is established.
