ABSTRACT.
The occurrence of Citrus exocortis viroid (CEVd), Citrus bent leaf viroid (CBLVd), Hop stunt viroid (HSVd), Citrus dwarfing viroid (CDVd), Citrus bark cracking viroid (CBCVd) and Citrus viroid VI (CVd-VI) in Citrus spp. cultivated in six provinces of Uruguay was surveyed in 2008- 2009 and 2009-2010 growing seasons using Northern blot hybridization. Sixty two per cent of surveyed trees were infected with either single or mixed viroid inocula, the latter being more abundant. CBCVd and CVd-VI were not detected in the samples analyzed. HSVd showed the highest prevalence (92%) among infected plants followed by CDVd (50%), CEVd (23%) and CBLVd (19%). The most frequently observed viroid combination was HSVd+CDVd. Our results showed that CEVd, CBLVd, HSVd, CDVd are widespread throughout citrus orchards in Uruguay and highlight the presence of mixed viroid infections. |

ABSTRACT.
The bronze bug Thaumastocoris peregrinus is an invasive pest, affecting Eucalyptus plantations worldwide. Although its natural enemy Cleruchoides noackae has been tested for the biological control of this pest, other strategies like the use of native entomopathogenic fungi are needed. For this, native virulent fungal isolates should be selected, massively multiplied in an efficient way, and prepared to obtain a stable product. Isolates of native Beauveria bassiana obtained from T. peregrinus and from different collections were screened for their virulence towards this insect and for their amenability to be massively produced in a low-input liquid submerged fermentation and prepared as a dry powder. Three out of six virulent strains were suitable for their massive production in a 2% corn flour suspension, achieving 109 submerged propagules/g of dehydrated preparation. The LC50 achieved by the dry submerged propagules did not differ from the LC50 of fresh aerial conidia. The proposed dual selection of strain and a complex substrate, and the procedures leading to the production of a dry preparation, allowed for high viability and virulence of the fungal spores of three strains.
