This contrasts to the reduced richness and diversity of the entire ground foraging ant
fauna in secondary forests of the Atlantic forest in Southern Brazil (Bihn et al.
Guy Theraulaz, who discovered "that ants are rule-driven systems." If a randomly foraging ant
finds a food source, he explains, it will head back to the nest, leaving a scent trail of pheromones behind.
The species accumulation curves (observed and estimated) show that the ground foraging ant
species assemblage was relatively well sampled, and that 92.1% (95% CI: 69.6 to 98.3%) of the local estimated species richness (Chao2) (44.5 species; 95% CI: 41.7 to 58.9) was collected (Fig.
An additional sampling method was utilized in October 1989 to detect diurnal foraging ant
species that may have been overlooked during transect sampling.
Adults emerge inside the host nest, mating occurs outside, females lay eggs into or on plant tissue, and the very mobile first-instar larvae (planidia) are presumed to attach to foraging ant
workers (or to intermediate hosts) for passive phoretic transport to the ant nest (Clausen 1940; Heraty 2000).
By 21 DAE, SiestaB, ArenaR, and TransportR had foraging ant
populations that were approaching pretreatment levels, while MaxforceB and AdvionB maintained lower numbers than the other treatments.
When the pesticide is mixed into sweet or fatty bait they like, foraging ants
carry bits back to the nest and share it with their mates.
Ants foraging activity on the plants was determined by counting the number of foraging ants
moving up and down the plant trunk for 3 min.
After that, the distribution of foraging ants
in the course of time became no longer random.
Furthermore, the number of foraging ants
significantly increased with increasing concentration of sucrose solutions ([chi square] = 8.615, df = 2, P = 0.013; Fig.
will carry the spinosad granules back to their nest, and the granules will kill the colony within a few days to a few weeks.
