“…All examined entomopathogenic fungal strains induced over 50% D. citri adult mortality within 5 days of exposure. Our findings are in line with the studies of Gandarilla-Pacheco et al [48] and Zhang et al [49], who reported B. bassiana to be pathogenic against D. citri . In addition, I. fumosorosea has also been evaluated in various studies and the findings revealed a reduction in the survival and developmental rate of D. citri post-exposure to the fungus [7,8,9].…”

Entomopathogenic fungi are commonly applied as inundative sprays to protect plants against insect pests. Their artificial establishment as fungal endophytes to provide other benefits to the host plants aside mere protection against the primary pests has also been widely demonstrated. In the present study, two fungal strains of Beauveria bassiana and one strain of Isaria fumosorosea were assessed in a pathogenicity test against adults of Asian citrus psyllid (Diaphorina citri) and found to induce 50% reduction in the survival rate of D. citri adults within 5 days of exposure. The ability of the three fungal strains to endophytically colonize Citrus limon, the impact on plant growth and the effects of systemic colonization on 3 successive generations of D. citri feeding on colonized plants was evaluated. Citrus seedlings at 4 months post-planting were inoculated with each of the fungal strains via foliar spraying. Both strains of B. bassiana successfully colonized the seedlings. One of the B. bassiana strains (BB Fafu-13) was sustained up to 12 weeks in the colonized seedlings, whereas the other B. bassiana strain (BB Fafu-16) was only recovered up to 8 weeks post-inoculation. Isaria fumosorosea (IF Fafu-1) failed to colonize the plant. Both strains of B. bassiana induced significant improvement in plant height and flush production in endophytically colonized seedlings. In addition, endophytic B. bassiana caused 10–15% D. citri adult mortality within 7 days of exposure. Female D. citri feeding on B. bassiana challenged plants laid fewer eggs as compared to those feeding on endophyte-free seedlings, while reduction in adult emergence was recorded on B. bassiana treated plants. With this study, we present the first evidence of B. bassiana artificial establishment as fungal endophyte in citrus plants and its negative effects on D. citri.

“…Entomopathogenic fungi have also been tested as biological control agents with promising results against both the Asian citrus psyllid and the potato psyllid. Conidia suspensions of the fungi Beauveria bassiana and Isaria fumosorosea were effective against D. citri nymphs (Gandarilla‐Pacheco et al , ) , and Metarhizium anisopliae and I. fumosorosea were effective against B. cockerelli (Lacey et al , ). Adult potato psyllid males could also be trapped by using volatile chemicals that mimic the pheromones found attractive by males (Guédot et al , ).…”

Candidatus Liberibacter species are Gram-negative bacteria that live as phloem-limited obligate parasites in plants, and are associated with several plant diseases. These bacteria are transmitted by insects called psyllids, or jumping plant lice, which feed on plant phloem sap. Citrus huanglongbing (yellow shoot) or citrus greening disease is associated with three different species of Ca. Liberibacter -Ca. L. asiaticus, Ca. L. africanus and Ca. L. americanus -all originally found on different continents. Ca. L. asiaticus is the most severe pathogen, spread by Asian citrus psyllid Diaphorina citri and causing devastating epidemics in several countries. Ca. L. africanus occurs in Africa where it is spread by the African citrus psyllid Trioza erytreae. Ca. Liberibacter solanacearum is associated with diseases in several solanaceous plants, and transmitted by potato psyllid Bactericera cockerelli. Zebra chip disease is causing large damage in potato crops in North America. In Europe Ca. Liberibacter solanacearum is associated with diseases of the Apiaceae family of plants, carrot and celery, and transmitted by psyllids Trioza apicalis and Bactericera trigonica. When Ca. Liberibacter is suspected as the disease agent, the diagnosis is confirmed by DNA-based detection methods. Ca. Liberibacter-associated plant diseases can be controlled by using healthy plant propagation material, eradicating symptomatic plants, and by controlling the psyllid populations spreading the disease.

“…La cepa CHE-CNRCB 303 de I. javanica tuvo una eficacia de control en ninfas de 93%, valor semejante al 97% obtenido por Mellín-Rosas et al (2016) trabajando con igual cepa y mismas condiciones de temperatura, humedad y fotoperíodo. El valor obtenido en este ensayo fue superior al obtenido por Padulla y Alves (2009) y Gandarilla-Pacheco et al (2013), quienes trabajaron con I. fumosorosea y obtuvieron valores de 48.4 y 84.3% y levemente inferior al de Conseschi (2013) que fue del 98%.…”

ResumenLa eficia de control de ninfas del tercer al quinto estadio de Diaphorina citri Kuwayama se evaluó con cepas de Metarhizium anisopliae (63%), Beauveria bassiana (63%), e Isaria javanica (94%) bajo condiciones de laboratorio. En huertas comerciales de naranja se obtuvo eficacia de control de 82% con B. bassiana y 83% con I. javanica, lo que las constituye en cepas candidatas para el control biológico de D. citri en huertas con manejo convencional, orgánico y áreas urbanas de Argentina.
