Fig. 4 in Light affects the homing ability of Solenopsis invicta (Hymenoptera: Formicidae) foraging workers

Fig. 4. The effect of white, blue, yellow, and red light, as well as total darkness (black) on time-to-trail-formation of workers of red imported fire ant, Solenopsis invicta (mean + standard error). Results for time-to-trail-formation in yellow light were significantly faster than for black (dark) and by inference white and blue are also faster than black. Time-to-trail-formation under white light was significantly different from red and by inference white was also faster than black. Red and black time-to-trail-formation results were not significantly different. *P <0.01 and **P <0.001.
