Aggregation is an important aspect of collembolan biology, and A. maritima has been shown to produce an aggregating pheromone.

Many collembolan species, mostly those living in deeper soil horizons, are parthenogenetic, which favours reproduction to the detriment of genetic diversity and thereby to population tolerance of environmental hazards.

EPNs have not had an adverse effect on mite and collembolan populations (Georgis et al. 1991), yet there is strong evidence that they affect the species diversity of other nematodes.
