Baiting tests were conducted to evaluate the effect of increasing Solenopsis invicta virus 3 (SINV-3) dose on fire ant colonies. Actively growing early-stage fire ant ( Solenopsis invicta Buren) laboratory colonies were pulse-exposed for 24 hours to six concentrations of SINV-3 (10 1 , 10 3 , 10 5 , 10 7 , 10 9 genome equivalents/μl) in 1 ml of a 10 % sucrose bait and monitored regularly for two months. SINV-3 concentration had a significant effect on colony health. Brood rating (proportion of brood to worker ants) began to depart from the control group at 19 days for the 10 9 concentration and 26 days for the 10 7 concentration. At 60 days, brood rating was significantly lower among colonies treated with 10 9 , 10 7 , and 10 5 SINV-3 concentrations. The intermediate concentration, 10 5 , appeared to cause a chronic, low-level infection with one colony ( n = 9) supporting virus replication. Newly synthesized virus was not detected in any fire ant colonies treated at the 10 1 concentration, indicating that active infections failed to be established at this level of exposure. The highest bait concentration chosen, 10 9 , appeared most effective from a control aspect; mean colony brood rating at this concentration (1.1 ± 0.9 at the 60 day time point) indicated poor colony health with minimal brood production. No clear relationship was observed between the quantity of plus genome strand detected and brood rating. Conversely, there was a strong relationship between the presence of the replicative genome strand and declining brood rating, which may serve as a predictor of disease severity. Recommendations for field treatment levels to control fire ants with SINV-3 are discussed.
