The application of biotechn'ology to crop improvement has been the focus of much research around the world. Tissue culture and selection of somaclonal variation were developed many years ago, followed more recently by molecular markers and genetic engineering. This meeting focused on providing updates on the actual successes to date on the application of several areas of biotechnology to wheat improvement. What is clear is that there continues to be optimism regarding the potential for biotechnology to be applied to wheat improvement. It is also noteworthy that as was predicted by many scientists, many approaches are proving more difficult in wheat than in other crops. Molecular markers, for example, are difficult to apply routinely given the large genome, hexaploid genetics, and lower levels of polymorphisms. New marker systems such as AFLPs and microsatellites are an improvement over previous RFLPs, but still require significant investments to achieve similar results possible in other, more amenable species. What is encouraging are the successes to identify the genetics of complex traits in wheat such as quality, Fusarium and rust resistance. Some of these will surely provide useful applications in wheat improvement and all mapping efforts provide critical genetic information for further studies at the gene level. These will be increasingly important as genomic approaches (gene expression, proteomics, etc.) become available and are applied to wheat. In many ways, these latest genomics approaches should be more 'genome independent' and thus readily applicable to large, complex genome species such as wheat. Coupled with the relatively easy ability to produce doubled haploids, wheat may prove to be an extremely important species for genomic studies.

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.
