“… Sinno et al (2021) found that aphids reared on B. bassiana -treated plants for their entire lifespan were negatively affected in terms of survival and fertility in comparison with control cohorts; Mseddi et al (2022) screened a wild strain of B. bassiana B12 that not only promoted several plant growth parameters after root inoculation, but also displayed toxicity toward A. gossypii following colonization in cotton plants. Zhu et al (2023) found that B. bassiana -inoculated maize plants can influence the eggs laying selectivity of O. furnacalis females by changing plant volatile profiles; and González-Mas et al (2021) found that when the cotton was colonized by B. bassiana , they emit a different blend of volatile compounds compared to uncolonized control plants, which can affect the feeding behavior of insect pests A. gossypii , S. frugiperda , and S. littoralis . Here, we have similar results that A. nomiae had the ability of plant colonization and showed a significant repellent effect on S. litura larvae, an important insect pest on soybean, in both selective and non-selective assays.…”

IntroductionAspergillus nomiae is known as a pathogenic fungus that infects humans and plants but has never been reported as an entomophagous fungus (EPF) that can provide other functions as an endotype.MethodsA strain of EPF was isolated and identified from diseased larvae of Spodoptera litura in a soybean field and designated AnS1Gzl-1. Pathogenicity of the strain toward various insect pests was evaluated, especially the ability to colonize plants and induce resistance against phytopathogens and insect pests.ResultsThe isolated EPF strain AnS1Gzl-1 was identified as A. nomiae; it showed strong pathogenicity toward five insect pests belonging to Lepidoptera and Hemiptera. Furthermore, the strain inhibited the growth of Sclerotinia sclerotiorum in vitro, a causal agent of soil-borne plant disease. It colonized plants as an endophyte via root irrigation with a high colonization rate of 90%, thereby inducing plant resistance against phytopathogen infection, and disrupting the feeding selectivity of S. litura larvae.DiscussionThis is the first record of a natural infection of A. nomiae on insects. A. nomiae has the potential to be used as a dual biocontrol EPF because of its ability to not only kill a broad spectrum of insect pests directly but also induce resistance against phytopathogens via plant colonization.

“…Volatile compounds may also play an important role in defensive strategy of plants against herbivores (Damodaram et al, 2021; Zhu et al, 2022). For example, some cereal crops produce volatiles to attract or repel granary weevil ( Sitophilus granaries ) and bark beetle ( Tribolium confusum ) (Piesik & Wenda‐Piesik, 2015; Wenda‐Piesik et al, 2016).…”

1. Drought has become more common and severe in many parts of the world due to climate change. The effect of water stress on insect oviposition preference that is key determinant for their fitness has received less attention.2. Here, we examined how water stress may affect oviposition selection of Ostrinia furnacalis for maize plants in the greenhouse, and tested difference in volatile compounds emitted from treated maize, and electronantennogram and bioassay responses of O. furnacalis to the volatile profiles in maize plants.3. Ostrinia furnacalis were more prone to lay eggs on the well-watered maize. Most plant volatile compounds differed significantly among the three water treatments, including increased emissions of β-caryophyllene, (E)-2-hexenal, and linalool, and decreased emission of (Z)-3-hexen-1-ol when subjected to increasing intensity of drought. Varied volatile profiles of maize may drive oviposition decision of O. furnacalis,because O. furnacalis showed a clear oviposition preference for (Z)-3-hexen-1-ol, while not for β-caryophyllene, (E)-2-hexenal, and linalool, at the concentration of 1000 ppm.5. This study advances understanding of drought effects on plant-insect interactions through volatile profiles. Our finding calls for attention to oviposition selection for insect pest management in agricultural settings, especially in regions under changing precipitation patterns.

“…There is an increase in attractive volatiles and reduced levels of defensive volatiles, influencing oviposition behavior. However, consuming tissues colonised by B. bassiana results in lower survival of larvae, pupae, and adults of O. furnacalis [26].…”

“…Zhu et al [26] studied the life cycle of O. furnacalis in maize plants colonised by B. bassiana and found a reduction in adults by the end of the evaluation period. They also stated that this could be attributed to low levels of nitrogenous compounds in plants inoculated with B. bassiana [26].…”

Endophytic Development of the Entomopathogenic Fungus Beauveria bassiana Reduced the Development of Galls and Adult Emergence of Leptocybe invasa in Susceptible Eucalyptus

Eucalyptus cultivation in arid regions is limited by the losses caused by the galling wasp, Leptocybe invasa Fisher and La Salle, 2004 (Hymenoptera: Eulophidae); it oviposits below the epidermis of the central veins, mainly on seedlings in nurseries and/or young plants in the field, causing galls where the insects develop. Galls modify the normal circulation of sap in vascular tissues, ultimately affecting the development of infested plants and resulting in slower growth. Eucalyptus genotypes tolerant to water stress are susceptible to L. invasa, and this pest has no effective control methods. Here, we aimed to (i) determine the initial infestation dynamics of L. invasa in Eucalyptus plants inoculated with Beauveria bassiana and (ii) identify any change in the development of galls. B. bassiana-inoculated seedlings were infested with L. invasa. Susceptible plants were unaffected, and gall development was negatively affected at multiple stages. A fungal solution containing B. bassiana reduced gall development and the emergence of L. invasa adults in eucalyptus plants at considerable rates. The total number of adult emergence holes was 89.74% fewer for inoculated plants when compared to uninoculated plants. These results can help develop B. bassiana products to control L. invasa in susceptible eucalyptus plants for improved, sustainable forestry.
