Mandarins and their hybrids are considered resistant to citrus leprosis. However, there are no studies addressing such resistance in the field under natural inoculation conditions. In this work we evaluated, through symptom analysis, the response to leprosis of 25 different genotypes of mandarins and hybrids from a ten-year-old orchard with a long history of the disease. We observed higher resistance levels among Citrus reticulata Blanco varieties and some of their hybrids, such as the Murcott tangor (C. reticulata x C. sinensis L. Osbeck), wich did not show any leprosis symptoms. C. deliciosa Tenore and C. clementina hort. ex Tanaka accessions and hybrids, such as Lee tangelo [(C. clementina x (C. reticulata x C. paradisi Macf)], were the most susceptible under natural conditions. However, even in those genotypes, most of the symptoms were observed in leaves and not in fruits, as often seen in sweet oranges (C. sinensis L. Osbeck), considered the most susceptible species of citrus to leprosis. This suggests that even susceptible accessions of mandarins are likely to show some level of resistance when compared to sweet oranges. |

Abstract: This study compared the insecticidal activity of liquid culture-produced blastospores and solid substrate-produced aerial conidia of Beauveria bassiana GHA and Isaria fumosorosea ARSEF3581 strains against Diaphorina citri adults. Insects exposed to 10(7) propagules/ml in a spray residue contact leaf bioassay died within 6 days at 25°C, with no significant differences between fungal treatments. At higher concentrations (10(8) propagules/ml), I. fumosorosea conidia killed psyllids faster compared to its blastospore formulation, i.e. 4 versus 5 days, respectively. In greenhouse tests, the same treatments applied to infested citrus plants (2 x 10(6) spores/ml) all significantly reduced the number of nymphs compared with the untreated controls over 3 weeks; however, only I. fumosorosea blastospores significantly reduced the number of F1 adult psyllids when compared with controls. Similar results were observed in the follow-up greenhouse test, where I. fumosorosea blastospores were the most effective treatment overall, reducing D. citri populations by about 60% after 21 days; by contrast, imidacloprid killed almost 100% of psyllids within a week in both tests. Fewer psyllids exhibited mycosis in the greenhouse (i.e. ~20 versus >- 87% in the laboratory). This is the first report comparing both conidial and blastospore formulations of B. bassiana and I. fumosorosea for the control of a psyllid pest. Field testing is required to determine how successful different spore formulations might be under various environmental conditions.
