“…Cladosposrium sp. has been also cited as a random phoretic fungus even though the entomopathogenic potencial of this genus has also been reported [83,84], giving two plausible explanations of its presence in spore suspension.…”

Bark beetles (Coleoptera, Scolytinae) carry a diverse filamentous fungal community sometimes acting as vectors or carriers of phytopathogens. In this study, mycobiota carried by two Tomicus species (Tomicus piniperda and Tomicus destruens) were investigated through (i) morphological and molecular identification of taxa; (ii) taxonomic richness, diversity, evenness, dominance and phoresy indices; (iii) ecological network analysis and (iv) statistical co-occurrence analysis. The studied mycobiota were formed by eleven taxa and showed a moderate fungal diversity with low evenness. The fungus Sydowia polyspora was significantly abundant and dominated the community. All the fungal taxa were randomly associated. Both insect species (T. piniperda and T. destruens) were collected from plantations of Pinus radiata infected by Fusarium circinatum. The ecological factors that could drive community ecology and phoretic links between fungi and bark beetles are discussed.

“…Pyrosequencing (454) yielded many more bacterial sequences than DGGE, as has been found in other studies of bacteria associated with sap sucking insects. For example, studies using DGGE or restriction fragment length polymorphism (RFLP) identified only three and four bacterial symbionts in the sweetpotato whitefly Bemisia tabaci (Hemiptera: Aleyrodidae) and Pentastiridius leporinus (Hemiptera: Cixiidae), respectively [5,19], compared to studies using 454 pyrosequencing describing 13 and 21 bacterial genera associated with the brown planthopper Nilaparvata lugens (Hemiptera: Delphacidae) [68] and the leafhopper Orosius albicinctus (Hemiptera: Cicadellidae), respectively [33].…”

“…Both are very common environmental fungi, including many plant commensals and pathogens [3,13]. A number of strains have also been isolated from insects, including some pathogenic ones [1,12,19]. More detailed work, including using finer-scale molecular markers, will be needed to determine whether these fungi are true mealybug associates or more transient environmental samples acquired via feeding [14].…”

Microbial Associates of the Vine Mealybug Planococcus ficus (Hemiptera: Pseudococcidae) under Different Rearing Conditions

Sap-feeding insects harbor diverse microbial endosymbionts that play important roles in host ecology and evolution, including contributing to host pest status. The vine mealybug, Planococcus ficus, is a serious pest of grapevines, vectoring a number of pathogenic grape viruses. Previous studies have shown that virus transmission is abolished when mealybugs are raised in the laboratory on potato. To examine the possible role of microbial symbionts in virus transmission, the archaeal, bacterial, and fungal microbiota of field and laboratory P. ficus were characterized using molecular and classical microbiological methods. Lab and field colonies of P. ficus harbored different microbiota. While both were dominated by the bacterial obligate nutritional symbionts Moranella and Tremblaya, field samples also harbored a third bacterium that was allied with cluster L, a lineage of bacterial symbionts previously identified in aphids. Archaea were not found in any of the samples. Fungal communities in field-collected mealybugs were dominated by Metschnikowia and Cladosporium species, while those from laboratory-reared mealybugs were dominated by Alternaria and Cladosporium species. In conclusion, this study has identified a diverse set of microbes, most of which appear to be facultatively associated with P. ficus, depending on environmental conditions. The role of various members of the mealybug microbiome, as well as how the host plant affects microbial community structure, remains to be determined.

“…Some authors claim that Beauveria bassiana is a "species complex", referring that different isolates have a restricted host, while others point out that this fungus has no host specificity [29]. Accordingly, several pests are susceptible to the entomopathogenic aptitude of this fungus, like Alphitobius diaperinus [36], whiteflies Bemisia tabaci and Trialeurodes vaporariorum [32], Capnodis tenebrionis [20], Lutzomyia longipalpis [2], Callosobruchus maculates [26] and Tetranychus urticae [10]. Some studies also indicate the presence of this fungus associated to several lepidopterans [2,3,7,13,22,32,36].…”

Fungal Diversity Associated to the Olive Moth, Prays Oleae Bernard: A Survey for Potential Entomopathogenic Fungi

Olive production is one of the main agricultural activities in Portugal. In the region of Trás-os-Montes, this crop has been considerably affected by Prays oleae. In order to evaluate the diversity of fungi on Prays oleae population of Trás-os-Montes olive orchards, larvae and pupae of the three annual generations (phyllophagous, antophagous and carpophagous) were collected and evaluated for fungal growth on their surface. From the 3,828 larvae and pupae, a high percentage of individuals exhibited growth of a fungal agent (40.6%), particularly those from the phyllophagous generation. From all the moth generations, a total of 43 species from 24 genera were identified, but the diversity and abundance of fungal species differed between the three generations. Higher diversity was found in the carpophagous generation, followed by the antophagous and phyllophagous generations. The presence of fungi displaying entomopathogenic features was highest in the phyllophagous larvae and pupae, with Beauveria bassiana as the most abundant taxa. The first report of Beauveria bassiana presence on Prays oleae could open new strategies for the biocontrol of this major pest in olive groves since the use of an already adapted species increases the guarantee of success of a biocontrol approach. The identification of antagonistic fungi able to control agents that cause major olive diseases, such as Verticillium dahliae, will benefit future biological control approaches for limiting this increasingly spreading pathogen.
