Food preference and foraging activity of ants: recommendations for field applications of low-toxicity baits.

Nyamukondiwa C, Addison P - J. Insect Sci. (2014)

Bottom Line: We found that L. humile's vineyard foraging activity was high and that movement of ant bait by C. peringueyi and A. custodiens in the vineyard was relatively low.Consequently, more bait stations need to be dispensed for more effective control of C. peringueyi and A. custodiens than for L. humile.Thus, future bait formulations should be tailor made to suit these specific food requirements if baits are to be successful in ant pest management.

Proportion of Anoplolepis custodiens positive of a calco red labeled bait source (where 1.0 = 100%) at different distances from the bait source in a vineyard at Plaisir de Merle farm. Ground and vine data were analyzed separately, and means with the same letter are not significantly different (Bars represent ±95% CI). High quality figures are available online.

f02_01: Proportion of Anoplolepis custodiens positive of a calco red labeled bait source (where 1.0 = 100%) at different distances from the bait source in a vineyard at Plaisir de Merle farm. Ground and vine data were analyzed separately, and means with the same letter are not significantly different (Bars represent ±95% CI). High quality figures are available online.

Mentions: Anoplolepis custodiens. The proportion of ants occurring on the ground was generally higher than those occurring in the vine canopy (Figure 2). Nevertheless, a considerable number of ants were caught on the vines, where they were observed tending mealybugs. There were no significant monthly differences in foraging activity during the three trial days (during December, January, and February) both on the ground and on the vine (Table 2). However, foraging distance during the three different months was significant both on the ground and on the vine (Table 2), with distance from the bait source being significant on the ground while on the vine there was no difference in number of marked ants until after 8 m (Figure 2). A significant drop in A. custodiens foraging activity occurred on the ground after 2 m (Figure 2).
