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 Linepithema humile positive of a calco red labeled bait source (where 1.0 = 100%) at different distances from the bait source in a vineyard at Joostenberg farm. There was a significant drop in foraging activity after 2 and 8 m from the vine canopy and on the ground respectively. 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: Linepithema humile. There were no significant monthly differences in L. humile foraging activity during the three different trial dates both on the ground and on the vine (Table 1). However, foraging activity was highly significant both on the ground and in the vine (Table 1), with distance generally decreasing from the bait source for both ground and vine sampled ants, which was to be expected (Figure 1). There was a significant drop in foraging activity after 2 m in the vine canopy and after 8 m on the ground (Figure 1).
