“…2 Achieving control of this pest has been challenging in a number of cropping systems including strawberries, cherries, caneberries and blueberries. [3][4][5][6] Integrated pest management (IPM) practices that previously relied on targeted insecticide sprays applied in response to pest monitoring have been replaced with prophylactic applications initiated when this fly is present and fruit begin to ripen. 2 This has resulted in a major increase in the number of insecticide sprays applied in these crops.…”

BACKGROUND: The invasive drosophilid pest, Drosophila suzukii Matsumura, is affecting berry production in most fruit-producing regions of the world. Chemical control is the dominant management approach, creating concern for insecticide resistance in this pest. We compared the insecticide susceptibility of D. suzukii populations collected from conventional, organic or insecticide-free blueberry sites. RESULTS

“…In California, which accounts for 74% of all raspberry production in the United States, Farnsworth et al. () calculated revenue losses of $36.4 million, equivalent to 2.07% of their realized revenues for conventional producers, and organic producers had revenue losses of $3.43 million, equivalent to 5.74% of their realized revenues, related to the control of D. suzukii between 2009 and 2014. The higher percentage losses in annual revenues for organic producers were due to the higher cost of insecticide inputs, which Farnsworth et al.…”

Drosophila suzukii Matsumura is a significant pest of soft-skinned fruit. Larvae of D. suzukii develop within the fruit making it unmarketable as fresh berries and increasing the risk of rejection by processors. We evaluated selected biopesticides for control of D. suzukii in fall red raspberries, Rubus idaeus L. The trial results highlight a small number of biopesticides with the potential to reduce infestation of Drosophila larvae in raspberries. In addition to the standard biopesticide spinosad, we found that sabadilla alkaloids and Chromobacterium subtsugae both reduced the number of Drosophila larvae in raspberry fruit. Treatments that included corn syrup as a feeding stimulant showed no significant difference in their infestation levels compared to treatments without the syrup. In the final week of the 5-week trial, treatments with rotations of either spinosad/C. subtsugae or spinosad/sabadilla alkaloids had a 67% and 57% reduction in infestation when compared to untreated raspberries. Treatments of spinosad alone on a 7 day rotation and C. subtsugae alone on a 3-5 day rotation both had a 62% and 61% reduction in larval infestation when compared to untreated raspberries.Third instar larvae, the largest and most damaging, were significantly reduced in plots treated with spinosad only, a rotation of spinosad/sabadilla alkaloids and the rotation of spinosad/C. subtsugae with corn syrup added when compared to untreated plots.This suggests that either of these biopesticides could be used as effective rotation partners along with spinosad for control of D. suzukii. Our results highlight that biopesticides can provide significant reduction in this devastating pest when used alone or in combination, providing options to support resistance management.

“…In the United States, for example, D. suzukii was initially discovered in Santa Cruz, California, in 2008, and since then has rapidly invaded many states and is a significant threat to fruit industries across the country 2 . For example, between 2009-2014, D. suzukii caused an estimated $39.8 million in revenue losses for the California raspberry industry alone 6 , and is responsible for 20%-80% crop losses in other fruit production areas 1,3,4,6 . Current methods to control D. suzukii rely considerably on the use of expensive, broad-spectrum insecticides (e.g., malathion), which have variable efficacy 5 , are difficult to use due to timing of fruit infestation 7 , and face the risk of D. suzukii evolving resistance 8 .…”

Synthetic gene drive systems possess enormous potential to replace, alter, or suppress wild populations of significant disease vectors and crop pests; however, their utility in diverse populations remains to be demonstrated. Here, we report the creation of the first-ever synthetic Medea gene drive element in a major worldwide crop pest, D. suzukii. We demonstrate that this drive element, based on an engineered maternal "toxin" coupled with a linked embryonic "antidote," is capable of biasing Mendelian inheritance rates with up to 100% efficiency.However, we find that drive resistance, resulting from naturally occurring genetic variation and associated fitness costs, can hinder the spread of such an element. Despite this, our results suggest that this element could maintain itself at high frequencies in a wild population, and spread to fixation, if either its fitness costs or toxin resistance were reduced, providing a clear path forward for developing future such systems.
