“…Crop infestation and economic losses caused by D. suzukii may depend on the population density, distance and seasonal movement of D. suzukii adults dispersing from alternate hosts, and these traits may largely depend on local climatic and habitat conditions. Drosophila suzukii can adapt physiologically and behaviourally to tolerate a wide range of temperatures and humidity, particularly if those conditions are localized or transient (Little et al., 2020). Drosophila suzukii is also a highly mobile pest, migrating between winter and summer seasons in Japan, to access better sources of host plants.…”

In China, D. suzukii is found in regions including Liuzhou, Guiyang, Zunyi and Hangzhou (Tan, 1949). Drosophila suzukii represents the most dominant drosophilid in orchards of cherry and Chinese bayberry, Myrica rubra (Myricaceae) (Chang et al., 2017; Chen, 1996; Wu et al., 2007). The species is highly adapted to a subtropical climate, it has widely invaded western countries, and it has a broad expanding distribution in other continents (dos Santos et al., 2017). Drosophila suzukii are known to penetrate the skin of intact ripening fruits to lay eggs inside their flesh with their highly sclerotized and serrated ovipositors (Atallah et al., 2014; Rota-Stabelli et al., 2013). Drosophila suzukii infest a wide range of host fruits, such as blueberries, blackberries, mulberries, raspberries, cherries and wine grapes, and other fruits with soft and thin skins (Lee, Bruck, Dreves,

“…Drosophila suzukii , an invasive species of Europe, Asia and North and South America (24, 25), is one potential target for such an approach. It has a number of generations per year and is often invasive in temperate climates that experience large seasonal temperature variations (26), providing opportunities for introducing a temperature-dependent population bottleneck as a method of suppression. As a proof-of-principle demonstration of this idea we sought to create a version of ClvR in Drosophila melanogaster in which Rescue function is temperature sensitive (TS; TS- ClvR ).…”

Gene drive that results in addiction to a temperature sensitive version of an essential gene triggers population collapse in Drosophila

One strategy for population suppression seeks to use gene drive to spread genes that confer conditional lethality or sterility, providing a way of combining population modification with suppression. Stimuli of potential interest could be introduced by humans, such as an otherwise benign virus or chemical, or occur naturally on a seasonal basis, such as a change in temperature. Cleave and Rescue (ClvR) selfish genetic elements use Cas9 and gRNAs to disrupt endogenous versions of an essential gene, while also including a Rescue version of the essential gene resistant to disruption. ClvR spreads by creating loss-of-function alleles of the essential gene that select against those lacking it, resulting in populations in which the Rescue provides the only source of essential gene function. In consequence, if function of the Rescue, a kind of Trojan horse now omnipresent in a population, is condition-dependent, so too will be the survival of that population. To test this idea we created a ClvR in Drosophila in which Rescue activity of an essential gene, dribble, requires splicing of a temperature-sensitive intein (TS-ClvRdbe). This element spreads to transgene fixation at 23° C, but when populations now dependent on TS-ClvRdbe are shifted to 29° C death and sterility result in a rapid population crash. These results show that conditional population elimination can be achieved. A similar logic, in which Rescue activity is conditional, could also be used in HEG-based drive, and to bring about suppression and/or killing of specific individuals in response to other stimuli.

“…This frugivorous pest was accidentally introduced to Europe and North America and has become a well-established economic pest in several countries in the recent years ( Cini et al, 2012 ; Asplen et al, 2015 ; Poyet et al, 2015 ). The fly’s ability to infest intact, ripening, soft-skinned fruits including grapes, combined with its high fecundity and short development cycle, makes it a severe economic threat, especially for the small-fruit industry ( Lee et al, 2011 ; Weißinger et al, 2019a ; Little et al, 2020a ). Additionally, lesions in the cuticle caused by oviposition serve as preferred entry sites for microorganisms, leading to secondary infections, e.g., with acetic acid bacteria ( Ioriatti et al, 2018 ; Ebbenga et al, 2021 ).…”

Physical and Chemical Traits of Grape Varieties Influence Drosophila suzukii Preferences and Performance

et al. 2021

The cuticle-covered surface forms the interface between plant parts, including fruits, and their environment. The physical and chemical properties of fruit surfaces profoundly influence plant-frugivore interactions by shaping the susceptibility and suitability of the host for the attacker. Grapevine (Vitis vinifera, Vitaceae) serves as one of the various host plants of the spotted wing drosophila, Drosophila suzukii Matsumura (Diptera: Drosophilidae), which is invasive in several parts of the world and can cause major crop losses. The susceptibility of wine towards this pest species differs widely among varieties. The objective of our study was to identify physical and chemical traits of the berry surface that may explain the differences in susceptibility of five grape varieties to D. suzukii. Both preferences of adult D. suzukii and offspring performance on intact versus dewaxed (epicuticular wax layer mechanically removed) grape berries were investigated in dual-choice assays. Moreover, the morphology and chemical composition of cuticular waxes and cutin of the different varieties were analyzed. Bioassays revealed that the epicuticular wax layer of most tested grape varieties influenced the preference behavior of adult flies; even less susceptible varieties became more susceptible after removal of these waxes. In contrast, neither offspring performance nor berry skin firmness were affected by the epicuticular wax layer. The wax morphology and the composition of both epi- and intracuticular waxes differed pronouncedly, especially between more and less susceptible varieties, while cutin was dominated by ω-OH-9/10-epoxy-C18 acid and the amount was comparable among varieties within sampling time. Our results highlight the underestimated role of the epicuticular surface and cuticle integrity in grape susceptibility to D. suzukii.
