“…Biological control agents are most frequently introduced in agricultural landscapes. Agro-ecosystems are often simplified ecosystems, with few native species and a low complexity of trophic networks, which makes them highly susceptible to invasion by exotic pests or pathogens ( Shea and Chesson 2002 ; Perrings 2011 ). As such, agro-ecosystems should also be susceptible to invasion by biological control agents, that is, establishment success should be higher in such environments where the low number of resident species leaves wide niche opportunities for potential invaders ( Shea and Chesson 2002 ).…”

Populations are introduced into novel environments in different contexts, one being the biological control of pests. Despite intense efforts, less than half introduced biological control agents establish. Among the possible approaches to improve biological control, one is to better understand the processes that underpin introductions and contribute to ecological and evolutionary success. In this perspective, we first review the demographic and genetic processes at play in small populations, be they stochastic or deterministic. We discuss the theoretical outcomes of these different processes with respect to individual fitness, population growth rate, and establishment probability. Predicted outcomes differ subtly in some cases, but enough so that the evaluating results of introductions have the potential to reveal which processes play important roles in introduced populations. Second, we attempt to link the theory we have discussed with empirical data from biological control introductions. A main result is that there are few available data, but we nonetheless report on an increasing number of well-designed, theory-driven, experimental approaches. Combining demography and genetics from both theoretical and empirical perspectives highlights novel and exciting avenues for research on the biology of small, introduced populations, and great potential for improving both our understanding and practice of biological control.

“…Although highly cited owing to a previous lack of invasion cost estimates, Pimentel's figures are not the key area of consensus that Sagoff implies (e.g., Holmes et al. 2009; Perrings 2011). Sagoff ignores more recent economic works that explicitly consider damage‐related costs (Bradshaw et al.…”

“…(2009) considered only forests and timber markets. In the other, Perrings (2011) states that the Pimentel et al. (2000, 2005) research “is still the most comprehensive summary of the control costs and lost output associated with invasive species in three productive sectors: agriculture, forestry and fisheries.” This affirmation continues to be the consensus view in invasion biology.…”
