0.208) or mortality after 1 hour (zɪ = -0.43, p = 0.670). Crazy ant mortality when
fighting fire ants was significantly higher than that of control crazy ants (Zι = -2.65, p =
0.008). Controls averaged 0.2 ± 0.2 dead crazy ants after 1 hour, whereas crazy ants
fighting fire ants had an average mortality of 2.7 ± 0.45 ants after 1 hour. Likewise,
fighting fire ants had significantly higher mortality after 1 hour than controls (Zj = -2.01,
p = 0.037).
Crazy ants receiving different diets
There was no fighting between crazy ants in any of the aggression assays; the
highest aggression score was a 2, which occurred only 5 times during the 144 observation
periods. Peak interaction score therefore was not significantly affected by diet treatments
(Z3 = 1.57, p = 0.667). There was no mortality for any of the ants after 5 minutes.
Neither mortality after one hour (Z3 = 2.95, p = 0.340) nor mortality after two hours (Z3 =
2.42, p = 0.491) were significantly affected by diet treatments. The overall average
mortality after two hours was 1.09 ÷ 0.21 out of 5 ants. This was not significantly
different from the average two-hour mortality of the five sets of Impowdered ants in a
Petri dish (Zι = 0.15, p = 0.694). Additionally, the 4 pairs that received the same diet did
not have significantly different mortality than the 5 unpowdered controls (zɪ = 0.00, p =
1.000).
Crazy ants receiving different diets vs. fire ants
Sugar level significantly affected the average interaction score (F1j20 = 4.97, p =
0.037), though protein type had no effect (Fii2o = 0.75, p = 0.398) and the interaction of
the two factors was not significant (F 1,20 = 1.16, p = 0.294). Ants receiving a lower sugar
diet had higher aggression scores when interacting with fire ants than did high sugar
