Volatile organic compounds emitted by Megaplatypus mutatus associated fungi: chemical identification and temperature-modulated responses by the ambrosial beetle

Ecological Processes, Год журнала: 2024, Номер 13(1)

Abstract Background In ambrosia and bark beetles–fungi interaction, volatile organic compounds (VOCs) play a central role in mediating various aspects of community dynamics beetles and/or fungi. These functions include facilitating beetle habitat location, mate identification, fungal partner differentiation. However, the understanding on this context remains limited, especially globally distributed subfamily Platypodinae, which comprises predominantly beetles. There is lack chemical data fungi from native South American species. This study addresses gap by characterizing VOCs twelve species associated with Megaplatypus mutatus assessing species-specific behavioral responses during dispersal. Methods Fungal were collected gas chromatography–mass spectrometry combined solid-phase microextraction Y-olfactometry assays males females performed at dispersal stage. Statistical analyses involved: non-metric multidimensional scaling multivariate plot PERMANOVA test, cluster analysis through unweighted pair group method Jaccard index, finally, chi-square goodness-of-fit test for assays. Results We identified 72 isolated M. galleries, exocuticle, gut. The olfactory behavior demonstrated its capacity to discriminate between profiles, showing preference either fungus or control source. Our results also enhance chemotaxonomic revealing beetle's remarkable low temperature tolerance capability maintain mobility orientation toward sources even after zero-degree Celsius exposure. Conclusion presents comprehensive insight into VOC emphasizing isolation within pest fungi, as well symbiotic Raffaelea genus. conclusion, our findings suggest that exhibits general aversion symbiont. notable exception arises when are pre-exposed 48 h freezing conditions, highlighting beetles' ability withstand conditions adults exhibit altered their associates under these circumstances.

Is Megaplatypus mutatus (Chapuis) (Curculionidae: Platypodinae) a threat to Khaya grandifoliola (Meliaceae)? Observations from Brazil

Revista Brasileira de Entomologia, Год журнала: 2025, Номер 69(1)

Опубликована: Янв. 1, 2025

ABSTRACT The ambrosia beetle Megaplatypus mutatus (Chapuis) (Coleoptera: Curculionidae: Platypodinae) is native to South America and an important forest pest in poplar plantations Argentina as well Italy where it has been introduced. Unlike most platypodine beetles, targets specifically live vigorous trees. We report for the first time attack on African mahogany trees, Khaya grandifoliola C. DC., by M. Brazil, indicating its preference trees with larger diameters. Most attacked exhibited only one or two gallery entrance holes, primarily along lower 2 m of trunk. However, colonization was impeded gummosis, a plant defense mechanism. Overall, rate low, nearly all them failing produce progeny. multivoltine life cycle study region, specimens captured traps baited beetle’s sex pheromone were females. Adults neither responded ethanol. Although successful reproduction not evidenced K. grandifoliola, initiation could still affect timber quality. Therefore, regular monitoring potential infestations recommended mitigate impacts tree health value. Additionally, we proposed here novel classification Platypodinae species into ‘A’ ‘B’ categories, based their behavioral patterns ecological interactions.

Abstract We provide scientists and decision-makers with up-to-date information on Megaplatypus mutatus (Coleoptera: Curculionidae: Platypodinae), a forest insect native to South America that has invaded other regions. Emphasis is given may prove relevant for the development of early detection, containment management programs improved risk analyses.

Mycobiomes of two distinct clades of ambrosia gall midges (Diptera: Cecidomyiidae) are species-specific in larvae but similar in nutritive mycelia

Microbiology Spectrum, Год журнала: 2023, Номер 12(1)

Опубликована: Дек. 14, 2023

ABSTRACT Ambrosia gall midges (AGMs) are mostly host plant-specific. In their galls, they harbor fungal symbionts on which feed. Therefore, represent unique steps in the evolution of gall-forming Cecidomyiidae (Diptera). Gall-associated fungi have been studied predominantly by cultivations, and potential larval endosymbionts completely neglected. Using ITS2 rRNA metabarcoding, we characterized mycobiomes individual compartments (gall surface, interior, larva) six species from two phylogenetically separated tribes (Asphondyliini Lasiopterini). Compared to surface larvae harbored significantly higher richness taxonomic diversity, a larger pool indicator taxa. Larval mycobiome composition was more species-specific; however, genera Fusarium , Filobasidium Tilletiopsis Alternaria Aureobasidium were taxa shared among species. Overall, 29% that can play functional role (e.g., initiation development or selection mycelia composition). The interior assembled least stochastically, its species-specific, being dominated Botryosphaeria dothidea (except for Lasioptera arundinis ). ambrosia galls offers environment supports growth similar fungi, regardless plant phylogenetic distance between AGM tribes. Our study illustrates range microorganisms indicative compartments, but function, especially larvae, remains be solved. IMPORTANCE endophagous insect herbivores whose live enclosed within single entire period. They may exhibit phytomycetophagy, remarkable feeding mode involves consumption biomass cultivated symbionts. Thus, AGMs ideal model organisms studying specificity insects. However, compared other fungus-farming insects, insect–fungus mutualism has is first use DNA metabarcoding characterize complete system insects as profiled surfaces, nutritive mycelia, larvae. Interestingly, different although evolutionary separation studied. confirmed long-time hypothesized paradigm important association this fungus with AGMs.

All Life, Год журнала: 2021, Номер 14(1), С. 610 - 621

Опубликована: Янв. 1, 2021

Chinese mitten crab, Eriocheir sinensis (Varunidae), is one of the most popular and widely cultivated freshwater crab species in food industry, with high commercial importance nutritional value. We analyzed diversity culturable fungi gut E. collected from a rice-crab co-culture system Tianjin, China. isolated 41 fungal strains male female crabs, using dilution plate method. Morphological molecular identification based on nuclear ribosomal internal transcribed spacer (ITS) sequencing suggested that these isolates belonged to 16 genera Ascomycota, Basidiomycota, Mucoromycota. Aspergillus was dominant identified genus followed by Penicillium Talaromyces. Yeasts, including Candida, Clavispora, Meyerozyma, Trichosporon genera, accounted for significant portion (12.2%) strains. Statistical analysis showed differences gut-associated communities between individuals showing higher diversity. Our study represents first report intestinal providing valuable microbiological information could be essential supporting effective management conservation this species, improvement economic performance industry.

Cladosporium - Insect Relationships

Опубликована: Дек. 21, 2023

The range of interactions between Cladosporium, an ubiquitous fungal genus, and insects, a class including about 60% the animal species, is extremely diverse. broad case history antagonism mutualism connecting Cladosporium insects reviewed in this paper based on examination available literature. Certain strains establish direct with pest or beneficial indirectly influence them through their endophytic development plants. Entomopathogenicity often connected to production toxic secondary metabolites, although there where these compounds have been reported favor pollinators attraction, suggesting important role angiosperm reproduction. Other relationships include mycophagy, which other hand may reflect ecological advantage for adaptable fungi using as carriers spreading environment. Several species colonize insect structures, such galleries ambrosia beetles, leaf-rolls attelabid weevils galls formed by cecidomyid midges, playing still uncertain symbiotic role. Finally, occurrence gut several has intriguing implications management, also considering that some proven be able degrade insecticides. These especially deserve further investigation understand impact control measures strategies preserve insects.
