“…Although effective, the GSS strains are prone to breakdown due to rare recombination events in males 14 . Further, isolation of D. suzukii tsl mutations could be challenging because the species prefers mild temperatures (20–26°C) and reproduces poorly at temperatures above 28°C 15,16 …”

BACKGROUND Drosophila suzukii (Matsumura, 1931, Diptera: Drosophilidae) is a global pest of soft‐skinned fruits such as blueberries, cherries and raspberries. Also known as spotted‐wing drosophila, D. suzukii is native to Asia but is now widely distributed in the Americas and Europe, and presents a serious challenge for growers. Genetic control strategies offer an environmentally friendly approach for the control of D. suzukii. RESULTS In this study, we developed transgenic strains of D. suzukii that carry dominant conditional female lethal transgenes. When raised in the absence of tetracycline, female D. suzukii die. We show that repeated releases of an excess of transgenic males can suppress D. suzukii populations in laboratory cage trials. CONCLUSION Our data suggest that the transgenic strain could provide an effective approach for control of this invasive pest of soft‐skinned fruits.

“…Enriquez & Colinet (2017) found a significant effect of temperature and exposure duration on pupae heat survival (observed 50% survival between 31 ∘ C [>200 h] and 37 ∘ C [0.5 h], whereas our data did not show such an effect. However, the results by Enriquez & Colinet (2017) are realistic, because also Evans et al (2018) observed pupae survival to decrease to 50% at 34 ∘ C for 72 h. Kinjo et al (2014) also found a significant decrease in pupae survival at 31 ∘ C during pupal development.…”

“…A large number of studies focused on the influence of temperature on D. suzukii's life cycle have already been published (see Winkler et al, 2020). Population increase of D. suzukii was found to be highest at 21 ∘ C (Tochen et al, 2014;Ryan et al, 2016), whereas hot summers with temperatures higher than 30 ∘ C (Harris et al, 2014;Kinjo et al, 2014;Tochen et al, 2014;Ryan et al, 2016;Evans et al, 2018) can reduce population size (Gutierrez et al, 2016;Tochen et al, 2016;Eben et al, 2018) and consequently infestation risk for ripening fruits. For a very short period of time, winter morph flies are also able to survive low temperatures up to −7.5 ∘ C (Stockton et al, 2019).…”

Drosophila suzukii is an invasive, polyphagous pest of soft-skinned fruits, having huge impact on fruit production in Asia, North and South America and Europe including Germany. 2 To investigate the effect of temperature on oviposition, egg-to-adult development success and duration, as well as immature heat survival and adult cold survival for a German D. suzukii population several experiments were conducted under different constant temperatures in the laboratory. The resulting life cycle data were described mathematically as functions of temperature and compared with experimental results of other researchers in a summary table. 3 Curve fittings used herein revealed that minimum, optimum and maximum temperatures are: 13.2, 26.7 and 33.6 ∘ C for oviposition, 14.1, 22.6 and 30.0 ∘ C for egg-to-adult development success, and 9.6, 27.3 and 35.7 ∘ C for egg-to-adult development duration. Eggs and larvae of D. suzukii showed a reduced heat survival within the tested temperature range of 29 to 41 ∘ C and exposure durations from 1 to 8 h. A cold survival rate of 50% was measured at e.g. −6 ∘ C for 4 h in summer morph adults and at e.g. −6 ∘ C for 45 h in winter morph adults confirming that the latter are more cold tolerant. 4 Results obtained in this study for a German population of D. suzukii are similar to those obtained for populations of other origins such as Canada, Japan, Spain and USA. Thus, presumably, present data based on a German D. suzukii population can be used for a new or fine-tune of already existing population dynamics models of D. suzukii in order to support an effective pest management strategy.

Drosophila suzukii (D. suzukii), commonly known as the spotted wing drosophila, is a highly invasive crop pest that is difficult to control using chemical insecticides. To address the urgent need for alternative and more sustainable control strategies, the sterile insect technique (SIT) is improved, which involves the release of sterilized male insects to mate with fertile conspecifics, thereby reducing the size of the pest population in the subsequent generation. The three critical aspects that influence the success of SIT programs in D. suzukii are addressed. First, an accurate and nondestructive method is established to determine the sex of individual insects based on the differential weight of male and female pupae. Second, conditions for X‐ray sterilization are systematically tested and an optimal dose (90 kV/40 Gy) is identified that ensures the efficient production of sterile D. suzukii for release. Finally, the inherent thermosensitivity of D. suzukii males is exploited to develop a temperature‐based sterilization technique, offering an alternative or additional SIT method for this pest. These advances will contribute to the development of a comprehensive and effective strategy for the management of D. suzukii populations, reducing their impact on agriculture and helping to safeguard crop yields.
