Title of Dissertation: USING THE FUNGUS METARHIZIUM ANISOPLIAE AS A MODEL SYSTEM TO STUDY THE ROLE OF GENE DUPLICATION, DIVERGENCE AND EXPRESSION IN ADAPTING TO PATHOGENICITY. Gang Hu , Doctor of Philosophy 2005 Directed By: Professor Raymond J. St. Leger Department of Entomology Fungal pathogens have been recorded for virtually all groups of multicellular organisms. They are the major cause of...

chemical insecticides have been widely employed for the control of storage grain pests. this has caused such problems as insecticide resistance along with contamination of foodstuffs with chemical residues. thus, there is a growing interest in using pathogenic control agents as alternative. in this study, the potential of beauveria bassiana (bbweevil™, a commercial product containing 2×109 coni...

Background. The New Zealand forest industry would greatly benefit from a successful way of controlling insect pests. The entomopathogenic fungus, Beauveria bassiana could hold such potential and has previously been shown to be capable of endophytic colonisation of the Monterey pine Pinus radiata. Nevertheless clarifications on its mode of transmission, persistence and action in this plant are r...

Simplicillium lanosoniveum is a species of Simplicillium, included in the Cordycipitaceae. This fungus known to have dual role as an entomopathogen against insect pests and antagonist disease pathogens plants. There are no reports on negative impact S. biological control. In Indonesia, research two roles still limited. Therefore, it necessary study potential these fungi be worthy analysis, base...
