“…In our study, M. anisopliae isolates showed higher mortality of 81-88% than B. bassiana isolates (51-77%) at 10 7 conidia/ml concentration. Suwannakut et al (2005) reported that variation in virulence can be attributed due to genetic diversity of the isolates, based on insect host and geographical region. This laboratory studies helped in identifying the local promising isolates for further field testing against P. xylostella in crucifer's crops.…”

Twenty isolates each of Beauveria bassiana and Metarhizium anisopliae were tested against the second instar larvae of Plutella xylostella through laboratory bioassay using larval dip method at the concentration of 1×10 7 conidia/ml. Higher larval mortality of 88.85% and 81.44%, were observed with NBAIR Ma-4 and NBAIR Ma-35 isolates of M. anisopliae and 77.36% with NBAIR-Bb-5a isolate of B. bassiana. Further studies on dose and time mortality with four isolates indicated lowest LC 50 value of 2.6×10 4 conidia/ml and LT 50 of 86.6 hours with NBAIR Ma-35 isolate. These isolates have to be further tested against P. xylostella in infested fields of cabbage and cauliflower.

Compounds known as phosphoramidates have been reported in the literature to have insecticidal activity. In the present investigation, four new phosphoramidates were synthesized and biologically evaluated with regard to their potential insecticidal activity. Moreover, another fifteen compounds had their biological activity profile re-evaluated in further detail against three Lepidoptera species of economic importance. The best results were observed with the four new organophosphates against Ascia monuste.

“…Similarly, a lower frequency of S. calamistis was recorded in B. bassiana treated maize plants compared to non-inoculated maize plants. 39 Research from Valda et al 40 and Godonou et al 41 proved the effectiveness of B. bassiana strains on a diamondback moth population, Plutella xylostella L. (Lepidoptera: Plutellidae). Similarly, the survivorship and development of banana weevil larvae, Cosmopolites sordidus Germar (Coleoptera: Curculionidae) were significantly affected by endophytic B. bassiana strains 35 as were the adult banana weevils as reported in Ghana.…”

Establishment of Beauveria bassiana isolates as endophytes in rice cultivars and their biocontrol efficacy against rice stem borer, Sesamia calamistis

et al. 2020

Possible endophytic colonisation of rice cultivar parts (leaves, stem and roots) by Beauveria bassiana isolates and their potential as biocontrol agents against Sesamia calamistis Hampson (African pink stem borer) were investigated. Five promising B. bassiana isolates were evaluated for their endophytic colonisation, the effectiveness of the inoculation methods and the efficacy of the isolates as biocontrol agents against S. calamistis. The plant part colonised is often dependent on the inoculation method. Colonisation of plant parts was assessed at 30 and 60 days after seed inoculation and foliar spray. For the pathogenicity activity, third instar larvae of S. calamistis were fed with rice stems that were previously inoculated with endophytic isolates of B. bassiana. Both inoculation methods led to the colonisation of the rice cultivar tissues, but were affected by the interactions of cultivars x isolates x inoculation methods. The colonisation of the cultivar plant parts varied over time (30- and 60-day intervals), and was affected by the inoculation method used. For both inoculation methods, highly significant differences were observed in the roots and the leaves over time (p=0.0001). However, with seed treatment, there was no significant difference in levels of colonisation in stems by the isolates x time (p=0.32). The B. bassiana isolates were pathogenic on the third instar larvae of S. calamistis, causing mortalities of more than 50% at 28 days after treatment. However, the virulence of the isolates varied. According to the isolates and the inoculation methods, B. bassiana formed an endophytic relationship with rice plants, and produced various mortality rates.
