Comparison of Mortality Factors
In trial 1, ant was frequently observed in the larvae-baited cages. In comparison, ant caused significantly more larval mortality than other mortality factors. Ant increased significantly (F 5 11.54; df 5 3,307; P 5 0.0001) over time (Fig.3A) in a linear manner (r 5 0.54), reaching ;90% at 28 days posttreatment. According to casual observation,
Solenopsis invicta Buren appeared to be the dominant species.
