“…In mature leaf tissues, Bb-5a recorded higher per cent colonization (88.89 %) at 30 DAFS and in young leaf tissues, Bb-5a and Bb-7 (100.0%) showed maximum per cent colonization at 15 DAFS respectively. Earlier reports (Akutse et al, 2013;Biswas et al, 2013) suggest that the differences in colonization rate between B. bassiana strains could be attributed to variations in growth rate and the tissue colonizing ability (endophytic) of each strain that is associated with the host plant. Posada and Vega, 2005 (in cacao), Akutse et al, 2013 (in broad/ common bean) and Biswas et al, 2013 (in white jute) reported similar differences in colonization frequency among B. bassiana isolates.…”

ABSTRACT:Glasshouse experiments were conducted to study the endophytic ability of six strains of entomopathogenic fungi Beauveria bassiana in maize leaf and stem tissues when applied through foliar sprays of oil formulations. B. bassiana treated and untreated control plants were artificially infested with second instar larvae of Chilo partellus to assess the stem borer damage. The variation in per cent colonization and persistence was observed in all the six strains in stem and leaf tissues of maize. The mean per cent colonization was observed in older stem tissues (16.67-46.67 %), in young stem tissues (22.22-52.22 %), in older leaf tissues (25.56-47.78 %) and in young leaf tissues (31.11-57.78 %). Evaluation of six B. bassiana strains, revealed that the isolate Bb-45 recorded the highest mean colonization in mature stem (46.67 %), mature leaf (47.78%) and also in relatively younger stem (52.22 %). The Bb-5a isolate also exhibited highest mean colonization in young leaf tissues (57.78 %). Lower percentage of dead hearts (2.2-11.1%) and lower stem tunneling (2.7-4.3cm/ plant) was observed significantly in B. bassiana treated plants as compared to the untreated control plants (28.86% of dead hearts and 13.41cm/plant stem tunneling).

“…Consequently, the total number of pupae and adults flies that were estimated from endophyte treated seedlings were fewer than for the controls. Similarly, Akutse et al (2013) reported that the life-history parameters of L. huidobrensis were significantly affected when the flies were fed on endophyte-treated faba bean seedlings. Similarly Akutse et al (2013) observed Hypocrea lixii to outperform other endophytic strains in reducing L. huidobrensis population.…”

We observed that the antagonistic effects of the three endophytic fungi were strain dependent.…”

“…In other studies, the use of bio-inoculants was demonstrated to induce systemic resistance against sucking, mining and stem boring insect pests (Martinuz et al, 2012a(Martinuz et al, , 2012bAkello and Sikora, 2012;Akutse et al, 2013). Bio-priming faba beans (Vicia faba) with endophytic fungal isolates belonging to the genus Beauveria, Trichoderma and Gibberella, for example, was reported to reduce aphid fecundity, lengthen nymph developmental time, as well as protect bean seedlings from aphid attack (Akello and Sikora, 2012).…”

“…Bio-priming faba beans (Vicia faba) with endophytic fungal isolates belonging to the genus Beauveria, Trichoderma and Gibberella, for example, was reported to reduce aphid fecundity, lengthen nymph developmental time, as well as protect bean seedlings from aphid attack (Akello and Sikora, 2012). Akutse et al (2013) and Akello and Sikora (2012) demonstrated that treating faba beans with the same isolates reduced the vegetable leaf miner (L. hudobriendsis) and the black bean aphid (Aphis fabae) fecundity, respectively. However, studies that have investigated the relationship between endophyte infection and leaf miner performance reveal that leaf miner response to microbial inoculants is highly dependent on the season, host plant, endophyte species as well as leaf miner species (Faeth and Hammon, 1997;Gange et al, 2007).…”
