Abstract
Survival of colonies of the red imported fire ant, Solenopsis invicta Buren, near its current northern range in the Georgia Piedmont during Oct.–Feb., 1975–76 was 96–100%. Workers moved brood underground when mound temperatures dropped to 10–12°C. Dead workers were removed from colonies following periods of −0°C. Workers, alate females, and males which were immobilized by −0° in the mounds were collected and held at room temperature, where recovery was 92.6%, 88.25% and 4%, respectively. S. invicta should be able to extend its present range based on lethal low temperatures as a limiting factor.This publication has 1 reference indexed in Scilit:
