“…In addition, in the present study freshly laid, sentinel egg masses were exposed for a maximum of 3 days, whereas in the United States naturally laid egg masses were collected, which have been reported to reveal higher parasitism levels than sentinel egg masses (Jones, Jennings, Hooks, & Shrewsbury, ). On the other hand, Dieckhoff et al () found in a nine years study conducted in northern Delaware (US) that the difference in parasitism levels between sentinel and naturally laid eggs was less pronounced. Since in the present study egg dissection was not performed, only successful parasitism based on emergence was evaluated.…”

“…Similarly, surveys performed in invaded areas in the United States showed that Anastatus spp. were the most efficient endemic parasitoids attacking sentinel H. halys egg masses (Cornelius et al, ; Dieckhoff et al, ; Haye, Fischer, et al, ; Jones et al, ). In addition, Anastatus sp.…”

Parasitism caused by indigenous egg parasitoids is generally low.…”

The invasive Halyomorpha halys (Heteroptera: Pentatomidae) is a key pest of fruits in the Emilia‐Romagna region of Italy. For the development of a sustainable management programme, knowledge of its native natural enemy community and its efficacy is essential. A three‐year field survey was conducted exposing H. halys egg masses in different types of habitats to investigate the efficacy of native natural enemies in reducing the H. halys populations in the Emilia‐Romagna region, where the stinkbug was first detected in 2012. Over the first year of the study, sentinel eggs from laboratory cultures were stapled to the underside of leaves in various host trees, whereas in following years H. halys adults were directly caged on branches in sleeve cages to allow natural oviposition. Over the examined years, low rates of parasitism (1%–3%) and predation (2%–5%) were observed. Parasitism was caused exclusively by the generalist parasitoid Anastatus bifasciatus.

“…Brown marmorated stink bug is a highly mobile polyphagous pest that can fly long distances (Bakken et al 2015). Different stages of brown marmorated stink bug are attacked by several species of native arthropod natural enemies (Abram et al 2017;Dieckhoff et al 2017). As an agricultural pest, it is a good candidate for biological regulation by predators and parasitoids, because it spends the majority of the year in non-managed, wooded habitats rather than in agricultural crops where pesticides often limit biological control.…”

“…However, there are very few post-release studies (Hajek et al, 2016) and none that we know of that can demonstrate evolution of host range. For example, six native parasitoid species from four genera could not adapt to increase their rates of parasitism on an invasive species, the brown marmorated stink bug (Halyomorha halys St al), which remained under 5% over a 9-year sampling period (Dieckhoff et al, 2017).

Novel environmental conditions experienced by introduced species can drive rapid evolution of diverse traits. In turn, rapid evolution, both adaptive and non-adaptive, can influence population size, growth rate, and other important ecological characteristics of populations. In addition, spatial evolutionary processes that arise from a combination of assortative mating between highly dispersive individuals at the expanding edge of populations and altered reproductive rates of those individuals can accelerate expansion speed. Growing experimental evidence shows that the effects of rapid evolution on ecological dynamics can be quite large, and thus it can affect establishment, persistence, and the distribution of populations. We review the experimental and theoretical literature on such eco-evolutionary feedbacks and evaluate the implications of these processes for biological control. Experiments show that evolving populations can establish at higher rates and grow larger than non-evolving populations. However, non-adaptive processes, such as genetic drift and inbreeding depression can also lead to reduced fitness and declines in population size. Spatial evolutionary processes can increase spread rates and change the fitness of individuals at the expansion front. These examples demonstrate the power of eco-evolutionary dynamics and indicate that evolution is likely more important in biocontrol programs than previously realized. We discuss how this knowledge can be used to enhance efficacy of biological control.
