Abstract Drosophila suzukii ( D. ) is a notorious pest that causes devastating damage to thin-skinned fruits because female flies use serrated ovipositor pierce the skin of ripening and lay eggs in flesh with ovipositor. The current application insecticides manage this has led serious resistance environmental hazards, so there an urgent need for alternative strategies. In present work, we reported identifying potential entomopathogen Bacillus cereus H1 B. H1) from their habitat was lethal adults following ingestion. First, isolated identified morbid pupae. Next, robustly arrested development fly progeny. Moreover, exerted adverse effect on survival locomotion adult flies. Mechanistically, disrupted intestinal homeostasis triggered oxidative innate immunity, resulting death within 5 days. To best our understanding, study first investigate role managing , suggesting it could be suitable candidate biopesticides suzukii. Future studies exploit mechanism underlying pathogenicity toward Spotted Wing would improve knowledge ecology host-entomopathogen interactions nature.

The essential oil of Pelargonium graveolens (PGEO) is identified in the literature as a rich source bioactive compounds with high level biological activity. This study aimed to examine chemical profile PGEO well its antioxidant, antibacterial, antibiofilm, and insecticidal properties. Its composition was analyzed using gas chromatography–mass spectrometry (GC-MS), achieving comprehensive identification 99.2% volatile compounds. predominant were β-citronellol (29.7%) geraniol (14.6%). PGEO’s antioxidant potential determined by means DPPH radical ABTS cation neutralization. results indicate higher capacity neutralize cation, an IC50 value 0.26 ± 0.02 mg/mL. Two techniques used assess antimicrobial activity: minimum inhibitory concentration (MIC) disk diffusion. Antimicrobial evaluation diffusion method revealed that Salmonella enterica (14.33 0.58 mm), which forms biofilms, Priestia megaterium (14.67 mm) most susceptible exposure PGEO. MIC assay demonstrated highest performance this EO against biofilm-forming S. (MIC 50 0.57 0.006; 90 0.169 0.08 mg/mL). In contrast contact application, assessment situ vapor phase antibacterial activity significantly more potent effects. An analysis antibiofilm MALDI-TOF MS disrupt biofilm homeostasis growing on plastic stainless steel. Additionally, evaluations indicated treatment at doses 100% 50% resulted complete mortality all Harmonia axyridis individuals.

The spotted wing drosophila (SWD), Drosophila suzukii Matsumura (Diptera: Drosophilidae), is an invasive polyphagous pest of soft-skinned fruit that has started to threaten small production in Europe since 2008. High reproductive capacity, short generation time, and difficulties visualizing early damage contribute its rapid spread. Currently, the control strategy against D. mostly relies on treatment with synthetic insecticides. Keeping mind this causes greatest during harvesting period, using chemicals not recommended due increased risk high pesticide residue levels fruit. With aim reducing use insecticides, there a need for developing environmentally safer way control. Alternative solutions could rely essential oils (EOs), which can be used conventional organic systems. Four oils, geranium (Pelargonium graveolens), dill (Anethum Scots pine (Pinus sylvestris), bergamot (Citrus bergamia), were assessed their insecticidal effects four different tests (contact toxicity, fumigant-contact repellent effect, multiple-choice tests). EOs applied dissolved acetone at three concentrations. most promising one was oil, had best effect all conducted tests, even lowest concentration. Geranium oil caused very mortality (95%), concentration applied, after 24 h test, it over 85% contact test. It also noticed demonstrated deterrent by repelling females from laying eggs days have moderate strong tests. 100% achieved highest Bergamot EO did any significant activity. Geranium, pine, great potential as friendly controlling they exhibit deterrent, repellent, effects.

The γ-aminobutyric acid (GABA) receptors play pivotal roles in the transmission of neuronal information nervous system insects, which has led these proteins to be targeted by synthetic and natural products. Here, we assessed insecticidal potential essential oil Pectis brevipedunculata (Gardner) Sch. Bip., a neotropical Asteraceae plant used traditional medicine, for controlling Drosophila suzukii (Matsumura) adults feeding exposure. By using silico approaches, disentangle contribution GABA other targets (e.g., acetylcholinesterase, glutathione-S-transferases) insects that may explain differential activities against D. two pollinator bees (Apis mellifera Linnaeus Partamona helleri Friese). Neral (26.7%) geranial (33.9%) were main components killed with an estimated median lethal concentration (LC50) 2.25 µL/mL. Both forager bee species, would likely contact this compound field, more tolerant did not have their diet consumptions affected oil. Based on molecular predictions three components, higher affinity interaction (geranial −6.2 kcal/mol; neral −5.8 kcal/mol) relation A. −5.2 −4.9 contribute explaining difference toxicities observed bioassays. Collectively, our findings indicated involvement P. as alternative tool suzukii.

Drosophila suzukii, an invasive insect pest, poses a significant threat to various fruit crops. The use of broad-spectrum insecticides control this pest can reduce the effectiveness biological agents, such as parasitoid Trichopria anastrephae. Here, we evaluated toxicity newly synthesized lactone derivatives on D. suzukii and their selectivity towards T. We used in silico approaches identify potential targets from most promising molecules nervous system understand differences susceptibilities between its parasitoid. Of nine tested, (rac)-8 compound 4 demonstrated efficacy against fly. Exposure estimated LC90 resulted mortality rate less than 20% for anastrephae without impairing parasitoid’s functional parasitism. predictions suggest that target gamma amino butyric acid (GABA) receptors transient receptor (TRP) channels suzukii. However, only reduced interaction with TRP reason these compounds Our findings integrating into management practices.
