higher in crazy ant addition locations than control locations (F 1,44= 3.697, p = 0.0610),
and crazy ant recruitment was higher for protein than for sugar (F^44 = 6.770, p = 0.0126,
Figure 3.7). The interaction between bait type and treatment was sizeable but not
significant (Fij44 = 2.825, p = 0.0990). There were no significant interactions with time
and any other factors. Fire ant recruitment decreased significantly through time (F4j∏6 =
5.154, p = 0.0006, Figure 3.6), but recruitment was not affected by treatment (F 1,44 =
0.026, p = 0.8718). Recruitment to protein baits was much higher than recruitment to
sugar baits (F 1,44 = 22.817, p < 0.0001, Figure 3.7). On average, per bait recruitment was
higher for fire ants than for crazy ants (Figure 3.6). Fire ants also controlled significantly
more protein baits (p = 0.0394) but not sugar baits (p = 0.1444) after 1 hour (on July 8
and 14). On both July 8 and July 14, there were no instances of crazy ants and fire ants
co-occurring at a protein bait (χ = 10.1931, p = 0.0006), yet there was no evidence of
sugar bait exclusion by either species (χ = 0.9470, p = 0.9538).
Summing all time periods, crazy ants discovered 16 of the baits in 10 minutes,
and fire ants discovered 15 of the baits. Protein baits were discovered in 10 minutes
significantly more often than sugar baits, regardless of species (χ = 11.242, p = 0.0008).
Fire ants and crazy ants did not differ in the amount of protein baits (p = 0.1489) or sugar
baits (p = 0.2734) they discovered. Protein baits were discovered more often than sugar
baits by both crazy ants (χ = 7.185, p = 0.0074) and fire ants (χ = 3.615, p = 0.0573).
Treatments did not affect the number of baits discovered by fire ants (χ = 1.810, p =
0.1785) or by crazy ants (χ = 2.467, p = 0.1163). Similarly, treatment had no effect on
average discovery time (Fij34 = 0.26, p = 0.6148) for the two species, and the treatment by
species interaction was insignificant (F 1,34= 0.03, p = 0.8742). In contrast, bait type
