“…One study showed that larval survival was highest on P:C 1:2 diets, while survival was decreased at lower protein diets (1:16, no carbohydrateonly diet was tested; Silva-Soares et al, 2017). Similarly, another study showed that more D. suzukii larvae survive on protein-rich diets (P:C 24:1), while survival was decreased at lower protein diets (P:C 1:12; Young, Buckiewicz, & Long, 2018). Comparing with these studies, our study suggests that different developmental stages may have different dietary requirements in D. suzukii.…”

Invasive animals depend on finding a balanced nutritional intake to colonize, survive, and reproduce in new environments. This can be especially challenging during situations of fluctuating cold temperatures and food scarcity, but phenotypic plasticity may offer an adaptive advantage during these periods. We examined how lifespan, fecundity, pre‐oviposition periods, and body nutrient contents were affected by dietary protein and carbohydrate (P:C) ratios at variable low temperatures in two morphs (winter morphs WM and summer morphs SM) of an invasive fly, Drosophila suzukii. The experimental conditions simulated early spring after overwintering and autumn, crucial periods for survival. At lower temperatures, post‐overwintering WM lived longer on carbohydrate‐only diets and had higher fecundity on low‐protein diets, but there was no difference in lifespan or fecundity among diets for SM. As temperatures increased, low‐protein diets resulted in higher fecundity without compromising lifespan, while high‐protein diets reduced lifespan and fecundity for both WM and SM. Both SM and WM receiving high‐protein diets had lower sugar, lipid, and glycogen (but similar protein) body contents compared to flies receiving low‐protein and carbohydrate‐only diets. This suggests that flies spend energy excreting excess dietary protein, thereby affecting lifespan and fecundity. Despite having to recover from nutrient depletion after an overwintering period, WM exhibited longer lifespan and higher fecundity than SM in favorable diets and temperatures. WM exposed to favorable low‐protein diet had higher body sugar, lipid, and protein body contents than SM, which is possibly linked to better performance. Although protein is essential for oogenesis, WM and SM flies receiving low‐protein diets did not have shorter pre‐oviposition periods compared to flies on carbohydrate‐only diets. Finding adequate carbohydrate sources to compensate protein intake is essential for the successful persistence of D. suzukii WM and SM populations during suboptimal temperatures.

“…Likewise, "Acolon" attracted more females than "Müller-Thurgau", but final oviposition was rather low in the first, and almost zero in the latter variety. Thus, while for the first attraction color, most likely together with volatiles [25], may be important cues for attraction, additional physical, and chemical cues determine the final host acceptance for oviposition [30], which should be investigated in more detail in future studies. In this regard, fruit firmness or skin penetration force are discussed to play a relevant role in D. suzukii oviposition ability, finding decreasing infestation with increasing penetration force [15,21,45].…”

“…Various visual, physical, and chemical factors may affect D. suzukii preference behavior for different plant species and varieties and offspring performance in different fruits, such as volatiles, size, color, skin firmness and penetration force, maturity, sugar content, acidity, and nutrient content [16,17,[25][26][27][28][29][30]. For example, D. suzukii utilizes visual cues such as fruit color as remote sensory information for host location [31].…”

“…According to the preference-performance hypothesis, female insects should have an oviposition preference for hosts on which offspring show the best performance [32,33]. For D. suzukii, positive relationships between adult preferences and offspring performance were indeed observed, e.g., in bioassays with wild and cultivated blueberries and in choice and no-choice assays using artificial diets with different protein-to-carbohydrate ratios [26,30]. In contrast, preference and performance did not match on different Prunus species [12] or when testing purees of different fruits [18].…”

Drosophila suzukii is an invasive fruit pest and represents a potential economic threat to viticulture. After first observations of D. suzukii in Europe in 2008, research mainly focused on the evaluation of the host range and infestation risk for fruit and berry crops. However, the risk assessment of D. suzukii in viticulture has only recently started. Understanding the factors influencing preferences of D. suzukii for host species and varieties as well as offspring performance is essential to improve management strategies. We investigated the field infestation of different grape varieties across Baden-Wuerttemberg, southwestern Germany, between 2015 and 2018. Moreover, we performed dual-choice assays in the laboratory to investigate whether adults show preferences for certain varieties and whether offspring performance differs between varieties. Furthermore, we studied the impact of grape damage on choice behavior. Field monitoring revealed that D. suzukii show preferences for red varieties, whereas almost no oviposition occurred in white varieties. The results of dual-choice assays confirmed that D. suzukii preference and performance are influenced by grape variety and that flies preferred damaged over intact "Pinot Noir", "Pinot Blanc", and "Müller-Thurgau" berries. Overall, these findings may have important implications for winegrowers regarding cultivated varieties, grape health, and insecticide reduction.

“…This results in slower establishment and build‐up of laboratory population and more time and care to rear them (Iacovone et al., ; personal observations). However, with increasing knowledge on the fly's biology (e.g., Hamby et al., ) and culturing methods (e.g., Sampson et al., ; Young, Buckiewicz, & Long,), (mass) rearing is becoming more feasible. Once a large population has been established, it can be kept under the right laboratory conditions.…”

The development of biological control methods for exotic invasive pest species has become more challenging during the last decade. Compared to indigenous natural enemies, species from the pest area of origin are often more efficient due to their long coevolutionary history with the pest. The import of these well‐adapted exotic species, however, has become restricted under the Nagoya Protocol on Access and Benefit Sharing, reducing the number of available biocontrol candidates. Finding new agents and ways to improve important traits for control agents (“biocontrol traits”) is therefore of crucial importance. Here, we demonstrate the potential of a surprisingly under‐rated method for improvement of biocontrol: the exploitation of intraspecific variation in biocontrol traits, for example, by selective breeding. We propose a four‐step approach to investigate the potential of this method: investigation of the amount of (a) inter‐ and (b) intraspecific variation for biocontrol traits, (c) determination of the environmental and genetic factors shaping this variation, and (d) exploitation of this variation in breeding programs. We illustrate this approach with a case study on parasitoids of Drosophila suzukii, a highly invasive pest species in Europe and North America. We review all known parasitoids of D. suzukii and find large variation among and within species in their ability to kill this fly. We then consider which genetic and environmental factors shape the interaction between D. suzukii and its parasitoids to explain this variation. Insight into the causes of variation informs us on how and to what extent candidate agents can be improved. Moreover, it aids in predicting the effectiveness of the agent upon release and provides insight into the selective forces that are limiting the adaptation of indigenous species to the new pest. We use this knowledge to give future research directions for the development of selective breeding methods for biocontrol agents.
