Fungal Entomopathogen

Beauveria bassiana is one of the entomopathogen fungi which is known as biological control agent of cocoa pod borer and cocoa mirids (Helopeltis spp.). Because of its effectiveness in the fields is still not consistent, so we conduct a research with the objective to know the possibility of Beauveria bassiana to be established as a endophyte. Various fungal entomopathogens have already been reported as endophytes and the various methods used to inoculate the plants with B. bassiana were partially effective. The research has been conducted in laboratory of Plant Protection, Indonesian Coffee and Cocoa Research Institute by inoculating of cocoa seeds and cocoa nursery with B. bassiana suspension.  The trial was arranged  by randomized complete block design with a factorial arrangement. The factor were spore concentration of B. bassiana (0; 2; and 4 g/ 10 l) and cocoa varieties (family of ICS 60, TSH858, and hybrid). The trial were use  four replications. The results showed that the fungal entomopathogen B. bassiana was established as an endophyte in cocoa seedling, both from cocoa seeds and nursery application. Percentage of existence of B. bassiana colonies as endophytes one month after seeds application were ICS 60 amounted to 93.3 % both on concentration treatments, while the families of TSH 858 by 80 % and 86.67 % respectively in 2 g and 4 g per 10 l of B. bassiana spores concentration treament.. The lowest percentage was in hybrids, which amounted to 66.67% and 50%. B. bassiana colonies was exixtence as an endophyte in culture from root, stem and leaves of cocoa seedling up to 5 months post inoculation. While the application on nursery by soil drenshing, leaf spraying, and stem injection , it was known that B. bassiana colonies were found in the tissues of leaves, stems, and roots until two months after application. Colonies of B. bassiana as endophytes still exsist until six weeks after nursery was planted in the field.

<p>Actualmente, en los municipios del departamento de Nariño (Colombia), en los cultivos de trigo y papa que son los principales sistemas de producción, se presentan altas infestaciones de poblaciones de chisas encontrándose hasta 350 larvas/m2, representando un factor limitante para la producción de los cultivos. Una alternativa promisoria para el manejo de esta plaga es la utilización de métodos biológicos que incluyen el uso de hongos entomopatógenos. El objetivo del presente trabajo fue el de evaluar el efecto de <em>Beauveria bassiana, Metarhizium anisopliae </em>sobre larvas de <em>Ancognatha scarabaeoides </em>en laboratorio e invernadero. Los aislamientos de hongos se obtuvieron de larvas infectadas en los municipios de Yacuanquer y Ospina. En el laboratorio, se seleccionaron 5 de 9 aislamientos de hongos: Mt1, Bb cosmo, Mt2, Bb4 y Bb10 que presentaron mortalidades superiores al 50%, éstas se evaluaron a concentraciones de 1x105 a 1x1010 esporas/ml. El porcentaje acumulado de mortalidad a los 18 días después de la inoculación fueron: del 100% para Bb cosmo, Mt1 y Mt2 en la concentración de 1x1010 esporas/ml y del 90% para Bb4 y Bb10 en la concentración de 1x109 esporas/ml, presentando concentraciones letales 90(CL90) de 1.1x1010, 7.3x109, 2.2x1010, 3.9x1010 y 4.3x1010 esporas/ml respectivamente. En invernadero se evaluaron los mismos microorganismos con sus respectivas concentraciones letales 50(CL50) y 90(CL90), encontrándose porcentajes de mortalidad del 76.00%, 67.50%, 63.50%, 59.00% y 53.50% para Mt1, Bb cosmo, Mt2, Bb4 y Bb10. Estos resultados indican la posibilidad de incluir estos biocontroladores nativos en el manejo integrado de las chisas en Nariño.</p><p> </p><p><strong>Evaluation of the biocontrol activity of <em>Beauveria bassiana, Metarhizium anisopliae</em>, on larvae of <em>Ancognatha scarabaeoides </em>(Coleoptera: Scarabaeidae).</strong></p><p>High grub populations of coleopteran, frequently attack crops of wheat and potato in the Department of Nariño, Colombia. Reports indicate that infestations levels reach more than 350 larvae/ m2, which severely reduce crop yields. Use of biological control measurements as fungal entomopathogens seems to be a promising alternative for management of this pest. The present work aimed to evaluate the effect of <em>Beauveria bassiana </em>and <em>Metarhizium anisopliae </em>on larvae of <em>Ancognatha scarabaeoides </em>both in laboratory and greenhouse conditions. Isolates of entomopathogen fungus were obtained from infected larvae in the municipalities of Yacuanquer and Ospina. A sample of 5 isolates, which previously had shown to cause mortality rates higher than 50%, was selected in the laboratory: Mt1, Bb cosmo, Mt2, Bb4 and Bb10. Isolates concentrations from 1x105 to 1x1010 spores/ml were tested. The cumulative mortality percentage (at 18 days after the inoculation) ranged from 100% with Bb cosmo, Mt1 and Mt2 at concentrations of 1x1010 spores/ml to 90% with Bb4 and Bb10 at concentrations of 1x109 spores/ml. Lethal doses 90 (LD90) of 1.1x1010, 7.3x109, 2.2x1010, 3.9x1010 and 4.3x1010 spores/ml were calculated for each isolate, respectively. An evaluation of the biocontrol activity of the isolates was carried out under greenhouse conditions. Mortality percentages obtained reached 76%, 67.5%, 63.5%, 59% and 53.5% for Mt1, Bb cosmo, Mt2, Bb4 and Bb10, respectively. These results suggest that the use of native biocontrolers is a promising alternative to be included in the integrated management for white grubs in Nariño.</p>

Colonization Patterns

The inoculation methods, the fungal strains, and several other factors are known to influent the success of fungal entomopathogens colonization in plants. The physiological status of the plant could also be another determinant. In the present study, the ability of three strains of Beauveria bassiana and one strain of Metarhizium anisopliae to successfully colonize Citrus limon plants and the influence of seedling age on endophytic colonization success was examined. Three, 4, and 6 months old seedlings were inoculated with 10 mL of 1 × 108 conidial·mL−1 suspensions of each of the four fungal strains via foliar spraying. All fungal strains successfully colonized citrus seedlings and were sustained up to 2 months in colonized plants irrespective of the seedling age, with differences in the mean percentage colonization recorded at various post-inoculation periods among the fungal strains. The highest percent endophytic fungi recovery rate was recorded in the 3 months old seedlings, where fungal mycelia of inoculated fungi were successfully re-isolated from 65.6% of the untreated newly developed leaf and stem tissues. One strain of B. bassiana, BB Fafu-12, significantly improved seedling height and leaf number. The study demonstrates the influence of seedling age on B. bassiana and M. anisopliae successful colonization in the citrus plant.
