“…Density-dependent benefit to homopterans from ant tending has been suggested several times (Banks 1962 (1) ants may have a limited dietary requirement for honeydew which is met by small aphid colonies, and/ or (2) ants may be unable to respond numerically to the often exponential growth of aphid colonies.…”

Abstract. We examined the impact of a tending ant, Formica altipetens, on the population dynamics of a membracid, Publilia modesta. Controlled ant-exclusion experiments revealed three ways in which the strength and occurrence of this mutualism was conditional. First, we detected yearly variation in the impact of ants on membracids. Ants had a significant positive impact on membracid abundance in 1985 and 1987, but not in 1986. Second, we found age-specific effects of ants on membracids. In 1985 and 1987 our experiments revealed that only membracid nymphs benefit directly from ant tending; we did not detect a direct positive impact of ants on the survival of membracid adults in any year. Third, we documented a density-dependent effect of ants on membracids. In 1985 and 1987, nymphs in large aggregations benefited from ant tending more than nymphs in small aggregations.Observations in 1985-1987 suggest that protection from a predatory salticid spider, Pellenes sp., may be at least one mechanism by which ants benefit membracid nymphs. In 1985 and 1987, when the association was mutualistic, spiders were significantly more abundant on membracid-infested plants without ants than on infested plants with ants, whereas this was not the case in 1986. We hypothesize that the age-specific benefits in this system may result because nymphs are especially susceptible to predation by spiders whereas the more agile and sclerotized adults are not.

“…Aphidophagous guilds are then regularly confronted with aphid-attending ants. Despite several papers on the impact of ants on aphidophagous species (Flanders, 1951;Banks, 1962;Buckley, 1987), few studies have described the possible impact of trophobiotic ants on interactions among aphidophagous predators. The impact of the ants on predators varies according to the ant species considered (Bristow, 1984).…”

Abstract. Since the publication of papers by Polis et al. (1989Polis et al. ( , 1992, intraguild predation (IGP) has been considered in numerous systems and a growing number of papers have been published, demonstrating the ubiquity and the importance of this interaction. It appears that aphidophagous guilds constitute especially favourable systems for IGP. Temporal and spatial distributions of aphids promote interactions, such as IGP, among natural enemies. However, despite extensive laboratory and field studies, several questions remain to be answered: Which traits of the different protagonists of the system may promote or hamper the occurrence of IGP? How do ants tending aphids modulate the interaction? How should one consider the "sub-lethal" effects (and the defensive mechanisms) associated with the risk of IGP? May IGP disrupt or enhance aphid control? These different issues are discussed by focusing on the predatory species in the complex system of aphidophagous guilds. It appears that, first, IGP may constitute one of the main forces influencing the structure and dynamics of aphidophagous guilds, and therefore it has to be taken into account in research studies, and second, because of the ephemeral nature of aphid colonies and the great number of species belonging to aphidophagous guilds, understanding all the implications of the interaction, both direct and indirect, constitutes a very complex task.

Adaptations of Coccinella magnifica, a myrmecophilous coccinellid to aggression by wood ants (Formica rufa group). II. Larval behaviour, and ladybird oviposition location1

Abstract. Like adults, larvae of the myrmecophilous ladybird Coccinella magnifica are rarely attacked by Formica rufa ants on for aging trails, but more often attacked on ant-tended aphid colonies. Larvae of the non-myrmecophile Coccinella septempunctata, to which C. magnifica was compared, were more readily attacked by ants in both situations. To avoid or counter ant aggression when foraging for aphids, C. magnifica larvae exhibit three main tactics: they may feed on un-or non-tended aphids; when feeding on tended colonies they often carry prey away, minimising time spent there; and if attacked, they use limited chemical defence. No novel behaviours were found in C. magnifica larvae, not occurring to some extent in C. septempunctata. Coccinella magnifica eggs were laid distant to ant-tended aphids, although closer to un-or non-tended aphids.
