Abstract After its initial discovery in California 2008, Drosophila suzukii Matsumura has become one of the most important invasive agricultural pest insects across climate zones much Asia, Europe, North America, and South America. Populations D. have demonstrated notable behavioral physiological plasticity, adapting to diverse environmental climatic conditions, interspecific competition, novel food sources, potential predators. This adaptability plasticity enabled rapid range expansion diversified niche use by suzukii, making it a species particularly suited changing habitats conditions. article reviews factors evidence that influence promotes this species’ invasiveness.

Spotted-wing drosophila, Drosophila suzukii (Matsumura) (Diptera: Drosophilidae), a vinegar fly of Asian origin, has emerged as devastating pest small and stone fruits throughout the United States. Tolerance for larvae is extremely low in fresh market fruit, management primarily achieved through repeated applications broad-spectrum insecticides. These are neither economically nor environmentally sustainable, can limit markets due to insecticide residue restrictions, cause outbreaks secondary pests, select resistance. Sustainable integrated programs include cultural control tactics various nonchemical approaches reducing populations that may be useful managing D. suzukii. This review describes current state knowledge implementation different controls including preventative such crop selection exclusion well strategies reduce habitat favorability (pruning; mulching; irrigation), alter resource availability (harvest frequency; sanitation), lower suitability fruit postharvest (cooling; irradiation). Because climate, horticultural practices, crop, underlie efficacy, feasibility, affordability tactics, potential these discussed across production systems.

Factors influencing oviposition behaviour of the invasive pest, Drosophila suzukii, derived from interactions with other Drosophila species: potential applications for control

Pest Management Science, Год журнала: 2023, Номер 79(11), С. 4132 - 4139

Опубликована: Июль 30, 2023

Drosophila suzukii (Matsumura) or spotted wing is a worldwide invasive pest of soft- and stone-fruit production. Female D. lay their eggs in ripening fruit the hatched larvae damage from inside, rendering it unmarketable causing significant economic loss. Current methods to reduce population field primarily rely on chemical insecticides which are not sustainable long-term solution increase risk resistance developing. Several studies demonstrate that when encounter coexist with other food source, this usually disadvantage suzukii, leading reduced oviposition increased larval mortality. These effects have potential be exploited management perspective. In review we summarise recent research articles focusing interspecific interactions between species aimed at understanding how drives behaviour.

Abstract Chemical control of Drosophila suzukii (Diptera: Drosophilidae) based on the use insecticides is particularly challenging as insect attacks ripening fruits shortly before harvest. An alternative strategy may rely yeasts phagostimulants and baits, applied canopy attract-and-kill formulations.

While the majority of Drosophila species lays eggs onto fermented fruits, females suzukii pierce skin and lay into ripening fruits using their serrated ovipositors. The changes oviposition site preference must have accompanied this niche exploitation. In study, we established an assay to investigate effects commensal microbes deposited by conspecific heterospecific individuals showed that presence on substrate enhances egg laying melanogaster biarmipes , but discourages D. . This result suggests a drastic change has taken place in lineage leading how respond chemical cues produced microbes. We also found hardness substrate, resembling either or damaged fermenting affects response microbial growth, indicating mechanosensory stimuli interact with chemosensory-guided decisions select avoid sites.

Implications of the Niche Partitioning and Coexistence of Two Resident Parasitoids for Drosophila suzukii Management in Non-Crop Areas

Insects, Год журнала: 2023, Номер 14(3), С. 222 - 222

Опубликована: Фев. 23, 2023

Understanding the mechanisms associated with coexistence of competing parasitoid species is critical in approaching any biological control strategy against globally invasive pest spotted-wing drosophila (=SWD), Drosophila suzukii (Matsumura). This study assessed two resident pupal parasitoids, Trichopria anastrephae Lima and Pachycrepoideus vindemiae Rondani, SWD-infested fruit, disturbed wild vegetation areas Tucumán, northwestern Argentina, based on niche segregation. Drosophilid puparia were collected between December/2016 April/2017 from three different pupation microhabitats fallen feral peach guava. These "inside flesh (mesocarp)", "outside flesh", but "soil", i.e., buried close to fruit. Saprophytic drosophilid (=SD) belonging melanogaster group SWD found all tested microhabitats. SD predominated both inside outside flesh, whereas soil. Both parasitoids attacked puparia. However, T. emerged mainly primarily P. mostly foraged less competitive microhabitats, such as soil or flesh. Divergence host choice spatial patterns same-resource preferences may mediate their non-crop environments. Given this scenario, have potential biocontrol agents.

Insects, Год журнала: 2025, Номер 16(3), С. 253 - 253

Опубликована: Март 1, 2025

Drosophila suzukii is an invasive pest that poses a significant threat to fruit crops worldwide, leading considerable agricultural losses and economic damage. Unlike chemical control measures against D. suzukii, integrating insect-proof nets within IPM framework offers more sustainable solution. This study evaluates the efficacy of nine commercial protective this pest, focusing on determining optimal hole dimensions based effects airflow velocity, temperature, morphometry net performance. To simulate field conditions in laboratory, we developed tubular device divided into three chambers with tested placed between two, incorporating fan generate thermo-anemometer. Our results confirm higher air velocities elevated temperatures reduce efficacy. Additionally, morphometric analyses lab-reared flies revealed sexual dimorphism strong temperature–size relationship, reared at lower being consistently larger, aspect also affects effectiveness. These findings highlight importance considering both abiotic factors morphology when evaluating screens, challenging assumption exclusion remains constant. Some proved completely effective SWD, supporting their use as preventive measure programs.

Ecofriendly control of Drosophila suzukii via the photoinsecticide chlorophyllin

Pest Management Science, Год журнала: 2025, Номер unknown

Опубликована: Апрель 9, 2025

Abstract BACKGROUND Drosophila suzukii is an invasive pest causing high losses of agricultural crops. Conventional treatment strategies are considered problematic for their risk inducing resistance and environmental harm. Photodynamic Inactivation (PDI) based on the photosensitizer‐mediated light‐dependent generation reactive oxygen species. Natural food‐grade photosensitizers, such as food additive sodium magnesium chlorophyllin (Chl, E140), have been proven effective against microbial pathogens several pests. The aim this study to assess whether principle Chl‐based PDI D. could be transferred from laboratory towards practical conditions. RESULTS We prove that photokilled after feeding 5 mM Chl with 3% sucrose (98.4% median moribundity, 9 h drug light interval, 78.9 J/cm 2 radiant exposure). Therefore, aspects safety feasibility were assessed, using streamlined variations same assay: required photosensitizer concentration reduced 0.5 (90.1% moribundity 6 days 315.6 illumination LEDs). was photoactivable sunlight (92.5% 294.5 1 Chl). Offering alternative lures did not impair effect. Photobleaching rendered non‐toxic (2.5% bleaching subsequent 157.8 ). Furthermore, fluorescence microscopy Chl‐fed flies confirmed accumulation in flies' intestines. CONCLUSION Our findings demonstrate harnessed a safe management © 2025 Author(s).
