Summary: The research aims to improve the decision-making process for managing D. suzukii in tart cherry. The study found a correlation between fruit development and D. suzukii infestation, allowing for pinpointing the timing of fruit susceptibility and the implementation of a more sustainable management program.

Summary: Using exclusion barriers made from fine-mesh netting is an effective organic compliant strategy to mitigate damage from D. suzukii on fall-bearing red raspberries. Applying the exclusion barriers early in fruit development is the most effective pest management strategy, reducing D. suzukii captures, infested fruit weights, and increasing marketable yield. However, it can also increase the weight of pollination deficient fruits.

Summary: This study found that the emergence of D. suzukii decreased exponentially with an increasing proportion of chicken manure in compost treatments, with a reduction of 95% when containing 25% chicken manure. Additionally, Drosophila melanogaster demonstrated a similar response to D. suzukii in the field.

Summary: The effects of jasmonic acid and salicylic acid on the elicitor induced defense in wine grapes against Drosophila suzukii were studied. It was found that these applications significantly affected the phenol, flavonoid and tannin contents of grapes, resulting in reduced damage and lower oviposition by the fruit flies. The results of this study can be used to develop management strategies for D. suzukii in wine grapes and related crops.

Summary: The spotted wing drosophila is an invasive pest that threatens small fruit production in Europe. Control with synthetic insecticides is not recommended due to the risk of pesticide residue. Essential oils, specifically geranium, Scots pine, and dill, show potential as environmentally friendly control options with repellent and insecticidal effects.

Summary: This study investigated the chemosensory cues influencing the oviposition behavior of SWD, finding that fruit ripeness and volatile chemistry play a significant role in attracting gravid flies. Gravid SWD flies show a clear olfactory preference for ripe and overripe fruits, with overripe fruits being the most attractive due to their high sugar content.

Summary: The study found that using H. uvarum as a bait can effectively attract D. suzukii while reducing the capture of non-target species.

Summary: In this study, semi-field cage trials were conducted in three locations in the United States to evaluate the effect of different seasonal spray regimes on Drosophila suzukii populations in blueberry and blackberry crops. The results showed that all treatment schedules resulted in reduced infestation compared to untreated control treatments, and there were no discernible differences between the two schedules in blueberry. It highlights the need for further research to determine the optimal timing and sequence of insecticide applications for controlling D. suzukii populations in fruit crops.

Summary: Control of spotted-wing Drosophila, Drosophila suzukii, in small fruits mainly relies on biological, cultural, and chemical methods. Research on host plant resistance as a genetic control strategy is still in early stages. In this study, a detached fruit bioassay was used to identify resistance patterns among 25 Vaccinium species and hybrids. Ten species showed strong resistance, including two wild diploids from the fly's native range and species from specific sections. Certain tetraploid and hexaploid blueberry genotypes displayed significant resistance against D. suzukii, preventing egg-laying and larval growth. This suggests the possibility of heritable resistance against this invasive fly species.

Summary: This study analyzed the effect of combined phosphine (PH3) fumigation and low-temperature treatment on the control of Drosophila suzukii. The results showed that the combination of low-temperature treatment and fumigation had a synergistic effect, except in the egg stage, and showed slight synergistic effects in larvae and pupae regardless of the combined treatment order.

Summary: Drosophila suzukii is an invasive pest that causes economic losses in berry production worldwide. This study compares the susceptibility of three important strawberry cultivars to D. suzukii and identifies the effect of fruit volatile compounds on pest attraction. The results show that both ripening stage and cultivar influence fruit choice, and the total amount of volatiles does not explain oviposition preference.

Summary: In this study, the nematode Steinernema rarum PAM 25 was evaluated for its control potential against Drosophila suzukii. The results showed that S. rarum PAM 25 is pathogenic to D. suzukii, with the most effective temperature and concentration being 14 degrees Celsius and 4,000 IJs/ml, respectively.

Summary: The combination of EF fumigation and cold-temperature treatment is effective for controlling D. suzukii. Cold treatment after EF fumigation showed the best synergistic effect. The concentration of fumigant during treatment also significantly affected the insecticidal activity of the combination treatment.

Summary: Managing spotted-wing drosophila in fruit crops is complicated due to the unreliable traps for monitoring adult flies and the difficulty of detecting larval infestations before fruit damage is apparent. A simple method involving extracting larvae from fruit in liquid, straining the solution, then counting them in a coffee filter has been developed for integrated pest management programs. Experiments showed that squeezing berries before immersion can improve the detection of smaller larvae, while immersing fruit for 30 minutes before counting larvae and using room temperature water for filtering can streamline the process. The use of a microscope for counting larvae was found to be the most effective approach.

Summary: The effect of cold storage on the development of Drosophila suzukii and the quality of strawberries was investigated. It was found that strawberries subjected to cold storage showed better maintenance of physicochemical characteristics and visual aspect, regardless of the maturation stage. In addition, cold storage was efficient in reducing the reproduction and development of Drosophila suzukii.
