Drosophila suzukii is native to East Asia and an invasive pest of fruit crops widely established in the Americas and Europe. The lack of effective indigenous parasitoids of D. suzukii in the invaded regions prompted surveys for co-evolved parasitoids in Yunnan Province, China, from 2013 to 2016. From banana-baited traps (2013–2015), 458 parasitoids of drosophilids were reared, comprised of Braconidae (49.56%), Figitidae (37.55%), Diapriidae (7.42%), and Pteromalidae (5.46%). Larval parasitoids… 
Surveys of Drosophila suzukii (Diptera: Drosophilidae) and Its Host Fruits and Associated Parasitoids in Northeastern China
Simple Summary Drosophila suzukii has become a globally invasive pest of thin-skinned berries and stone fruits such as strawberries, blueberries, raspberries, blackberries, and cherries. D. suzukii
Drosophila parasitoids (Hymenoptera) of Japan
TLDR
The Drosophila parasitoid system is an excellent model for the study of biological and ecological interactions in Japan and extensive studies have been carried out since the early 2000s, providing up‐to‐date information on their diversity, distributions, host use and reproductive mode.
Functional Responses of Three Candidate Asian Larval Parasitoids Evaluated for Classical Biological Control of Drosophila suzukii (Diptera: Drosophilidae)
TLDR
Three larval hymenopteran parasitoids showed a linear (type I) functional response to the tested host densities and the selection of parasitoid species to be released in North America and Europe to suppress D. suzukii was discussed.
Adventive larval parasitoids reconstruct their close association with spotted-wing drosophila in the invaded North American range
TLDR
This study demonstrates that the close association between the two larval parasitoids and D. suzukii that exists in Asia has evidently been reconstructed in North America, resulting in the highest parasitism levels of the globally invasive fruit pest yet recorded outside of its area of origin.
Host searching and host preference of resident pupal parasitoids of Drosophila suzukii in the invaded regions.
TLDR
Investigation of host searching and host preference of the three pupal parasitoid species Trichopria drosophilae (Perkins), Pachycrepoideus vindemmiae (Rondani) and Spalangia erythromera Förster found they have the potential to find and parasitize D. suzukii in the field.
Multiscale Determinants Drive Parasitization of Drosophilidae by Hymenopteran Parasitoids in Agricultural Landscapes
TLDR
Since they can tolerate a broad range of habitat factors, altogether pupal parasitoids investigated could play a role in biological control programs to suppress D. suzukii, but non-target effects have to be regarded.
The Description of an Efficient Trap for Monitoring Drosophila suzukii Parasitoids in Organic Soft Fruit Crops, and a New Record of Ganaspis brasiliensis (Ihering) (Hymenoptera: Figitidae) from Michoacan, Mexico
TLDR
It is concluded that it is possible to promote this species as a biological control agent through inoculation and conservation in organic production of blackberry against D. suzukii, through an “Augmentoria” strategy using the authors' sentinel trap with chocolate baits and preferred host of SWD to attract more SWD-parasitoids.
First Report of Leptopilina japonica in Europe
TLDR
The presence of Leptopilina japonica, the first record of this larval parasitoid in Europe, is reported for the first time and natural enemies may play an important role in regulating this pest.
First Record and Distribution of Ganaspis brasiliensis (Hymenoptera: Figitidae: Eucoilinae), a Parasitoid of Drosophila suzukii (Diptera: Drosophilidae) in Argentina
TLDR
The eucoiline species Ganaspis brasiliensis (von Ihering) is recorded for the first time in Argentina, with confirmation of parasitism of Drosophila suzukii infesting healthy raspberry fruit still on the plant.
New records of Leptopilina, Ganaspis, and Asobara species associated with Drosophila suzukii in North America, including detections of L. japonica and G. brasiliensis
TLDR
The findings illustrate the need for revisiting species concepts within Asobara, as well as host and geographic distribution data due to cryptic and/or misidentified species, and add to the list of cases documenting adventive establishment of candidate classical biological control agents outside of their native ranges.

TLDR
Several of the South Korean parasitoid species have the potential for use in classical biological control and may contribute to the suppression of D. suzukii in the newly invaded regions.
Drosophila parasitoids in northern Italy and their potential to attack the exotic pest Drosophila suzukii
TLDR
The field survey results showed a relationship between parasitoids and indigenous Drosophila communities and a high host competition, and beg further investigations of indigenous enemies, particularly T. cf.

Seasonal occurrence of resident parasitoids associated with Drosophila suzukii in two small fruit production regions of Italy and the USA
TLDR
Low numbers of parasitoids relative to initial larval load in baits suggest a limited effect of indigenous parasitoid populations on D. suzukii in these two fruit production regions, and highlights the need for improved biological control of D.suzukII through introduction or augmentation of specialist parasitoidal populations from the native range.
