“…Kruitwagen et al ( 2018 ) proposed to exploit intraspecific variations in biocontrol traits by selective breeding and illustrated their approach with parasitoids of Drosophila suzukii . Interestingly, a few years later, Jarrett et al ( 2022 ) experimentally evolved two species of pupal parasitoids of D. suzukii and found that parasitism rate increased after only three generations. Nachappa et al ( 2011 ) artificially selected lines of the predatory mite Phytoseiulus persimilis to improve their prey consumption, conversion efficiency, or dispersal.…”

While ecological interactions have been identified as determinant for biological control efficiency, the role of evolution remains largely underestimated in biological control programs. With the restrictions on the use of both pesticides and exotic biological control agents (BCAs), the evolutionary optimization of local BCAs becomes central for improving the efficiency and the resilience of biological control. In particular, we need to better account for the natural processes of evolution to fully understand the interactions of pests and BCAs, including in biocontrol strategies integrating human manipulations of evolution (i.e., artificial selection and genetic engineering). In agroecosystems, the evolution of BCAs traits and performance depends on heritable phenotypic variation, trait genetic architecture, selection strength, stochastic processes, and other selective forces. Humans can manipulate these natural processes to increase the likelihood of evolutionary trait improvement, by artificially increasing heritable phenotypic variation, strengthening selection, controlling stochastic processes, or overpassing evolution through genetic engineering. We highlight these facets by reviewing recent studies addressing the importance of natural processes of evolution and human manipulations of these processes in biological control. We then discuss the interactions between the natural processes of evolution occurring in agroecosystems and affecting the artificially improved BCAs after their release. We emphasize that biological control cannot be summarized by interactions between species pairs because pests and biological control agents are entangled in diverse communities and are exposed to a multitude of deterministic and stochastic selective forces that can change rapidly in direction and intensity. We conclude that the combination of different evolutionary approaches can help optimize BCAs to remain efficient under changing environmental conditions and, ultimately, favor agroecosystem sustainability.

“…Release of P. vindemmiae have also shown mixed results (Hogg et al, 2022). However, both parasitoids show a potential for rapid adaptive evolution by increasing, after only 3 generations, their developmental success from 88 to 259% (Jarrett et al, 2022). Although they are the most widely used and effective, pupal parasitoids intervene after damage is already caused by D. suzukii.…”

The Green Revolution has greatly changed agricultural production methods. Agriculture has become more specialized and intensive, and the use of phytopharmaceutical products, including insecticides, has intensified. However, these are harmful to the environment and human health. At the same time, globalization has led to the introduction of alien species (called invasive), whose establishment in Europe has been facilitated by the abundance of nutritive resources and the absence of natural enemies. These observations are particularly true with Drosophila suzukii. This fly is now considered as the main fruit pest in the world. Thus, it is becoming urgent to find alternative control methods to insecticides to counter the economic damage caused by this new pest. However, the development of an integrated pest management approach requires an excellent understanding of the biology and ecology of the species. In this paper, we first present the state of knowledge on the life cycle, host plants and phenology of D. suzukii. The current geographical distribution and the history of invasion of this pest are detailed, before estimating the extent of the economic losses caused. In a second part, the known alternative control methods against D. suzukii are listed: cultural practices, post-harvest treatments, sterile insect releases, uses of natural enemies and behavioral manipulations (visual and olfactory). Finally, in a third part, we will see how these methods can be combined to improve the control of this pest.

“…The few studies to date highlight the variable responses of parasitoids to selection imposed by a novel host that may stem from differences in the parasitoid's initial host range, life history traits, or standing genetic variation within the population. For example, out of three native parasitoids that were selected for improved performance on the invasive spotted wing drosophila ( Drosophila suzukii ) (Matsumura) (Diptera: Drosophilidae), two have been shown to increase developmental success on the invasive host (Jarrett et al, 2022 ; Kruitwagen et al, 2021 ). Selection somewhat increased the attack rate but not the developmental success of the larval parasitoid Leptopilina heterotoma (Thomson) (Hymenoptera: Figitidae) (Kruitwagen et al, 2021 ), while developmental success of two pupal parasitoids Pachycrepoideus vindemmiae (Rondani) (Hymenoptera: Pteromalidae) and Trichopria drosophilae (Perkins) (Hymenoptera: Diapriidae) increased significantly after only three generations of selection (Jarrett et al, 2022 ).…”

Co‐evolved natural enemies provide sustainable and long‐term control of numerous invasive insect pests, but the introduction of such enemies has declined sharply due to increasing regulations. In the absence of co‐evolved natural enemies, native species may attack exotic invasive pests; however, they usually lack adaptations to control novel hosts effectively. We investigated the potential of two native pupal parasitoids, Pachycrepoideus vindemmiae and Trichopria drosophilae, to increase their developmental success on the invasive Drosophila suzukii. Replicated populations of the two parasitoids were subjected to 10 generations of laboratory selection on D. suzukii with Drosophila melanogaster serving as the co‐evolved host. We assessed developmental success of selected and control lines in generations 0, 3, and 10. Changes in host preference, sex ratio, development time, and body size were measured to evaluate correlated responses with adaptation. Both parasitoid species responded rapidly to selection by significantly increasing their developmental success on the novel host within three generations, which remained constant for seven additional generations without further improvement. The generalist parasitoid species P. vindemmiae was able to reach similar developmental success as the control populations, while the performance of the more specialized parasitoid T. drosophilae remained lower on the novel than on the co‐evolved host. There was no increase in preference towards the novel host over 10 generations of selection nor were there changes in development time or body size associated with adaptation in either parasitoid species. The sex ratio became less female‐biased for both parasitoids after three generations of selection but rebounded in P. vindemmiae by generation 10. These results suggest that a few generations of selection may be sufficient to improve the performance of native parasitoids on invasive hosts, but with limits to the degree of improvement for managing invasive pests when exotic co‐evolved natural enemies are not available.
