“…Thus, the best way to test the efficacy of fungal isolates against the banana weevil might be when used as entomopathogens or endophytic entomopathogens. Studies about the endophytic use of B. bassiana for the management other plant pests for example: aphid (Myzus persicae) infection in tobacco (Nicotiana tabacum) [66], and the leaf miners (Liriomyza sativae and L. trifolii) in French beans (Phaseolus vulgaris) [54,67] resulted in improved plant vigour and development. Similarly, the use of endophytic B. bassiana resulted in the management of the Asian corn borer (Ostrinia furnacalis) in maize [68] and diamond back moth (Plutella xylostella) infection of cabbage (Brassica oleracea) [69].…”

The banana weevil (Cosmopolites sordidus) and the burrowing nematode Radopholus similis represent two of the most important pests of bananas. Previously, colonization of banana plants by the non-pathogenic Fusarium oxysporum (isolate V5w2) and the entomopathogenic Beauveria bassiana (isolate WA) have been shown to increase host resistance to various banana pests and diseases. However, there is limited data on how the combined inoculation of these isolates would affect field performance of bananas. In this study, the fungal endophytes were inoculated separately and in combination. Tissue cultured plantlets of cooking banana cultivar Mbwazirume and dessert banana cultivar Grande Naine were inoculated by root drenching with a suspension of 1.0 × 107 spores mL−1 of the endophytes on three occasions, separated 4 weeks apart, before transplanting into the field. Each plantlet was further inoculated with 1800 nematodes, composed primarily of R. similis. Inoculation of banana plants with the fungal endophytes significantly reduced nematode densities by >34%. Similarly, plant toppling was lower in the endophyte-enhanced plants (<16.5%) compared with the control (23.3%). We also observed improved yield of the first crop cycle in the endophyte-enhanced plants, which yielded >11 t ha−1 year−1 versus 9 t ha−1 year−1 achieved in the non-inoculated plants. These findings demonstrate the benefits of fungal endophytes in improving the yield of both cooking and dessert bananas via suppression of nematode densities and nematode-related damage.

“…The Arthropod Pathology Unit (APU) of the International Centre of Insect Physiology and Ecology (icipe) has a collection of more than 300 EPFs classified into Beauveria, Metarhizium and Isaria, among others [28]. Efficacy of these EPFs has been tested against a number of plant pests including leaf miners: Liriomyza sativae (Blanchard) and L. trifolii (Burgess) [29,30], L. huidobrensis (Blanchard) [31], Spoladea recurvalis (Fabricius) [32], stem borers: Chilo partellus (Swinhoe) and Busseola fusca (Fuller) [29,33,34], pod borers: Maruca vitrata (Fabricius) [35], sap-sucking: Megalurothrips sjostedti (Trybom) [36], Aphis craccivora (Koch) [37] and fruit flies: Ceratitis capitata (Weidemann), C. rosa (Karsch), C. cosyra (Walker) [38] and Zeugodacus cucurbitae (Coquillett) [39], among others. Similarly, Real IPM Ltd., Thika, Kenya, has a collection of several potential fungal isolates isolated from various locations within Kenya.…”

The banana weevil (BW), Cosmopolites sordidus, is the main coleopteran pest of banana, causing up to 100% yield loss. In this study, we screened 20 isolates of entomopathogenic fungi (EPF) for the management of BW. In the lab, eight Beauveria bassiana isolates caused >50% mortality of the adult BW, whereas Metarhizium anisopliae and Isaria fumosorosea isolates were less pathogenic. B. bassiana isolates ICIPE 648, ICIPE 660 and ICIPE 273 were the most pathogenic, killing ≥80% of adult BW. B. bassiana isolate ICIPE 622 yielded the highest spores per BW cadaver (1.84 × 108 spores), followed by ICIPE 660, ICIPE 273 and ICIPE 648—1.17 × 108, 3.8 × 107 and 3.6 × 107 spores, respectively. ICIPE 273 had the shortest LT50 (5.3 days) followed by ICIPE 648 (9.8 days) and 660 (11.1 days). Similarly, the LC50 values for the three isolates were 5.18 × 107, 5.49 × 107 and 5.2 × 107 spores mL−1, respectively. In the field, ICIPE 273 and ICIPE 648 had the highest (31.3%) and lowest (20.8%) pathogenicity, respectively. This study indicates that the B. bassiana isolates ICIPE 273, ICIPE 648 and ICIPE 660 are potential candidates for the environmentally sustainable management of BW.
