| evaluation of pathogenicity of the fungi metarhizium anisopliae and beauveria bassiana in hazelnut weevil (curculio nucum l., coleoptera, curculionidae) larvae. | the nut weevil (curculio nucum) is one of the most important and widespread pests in hazelnut orchards. in order to screen entomopathogenic fungal strains with high virulence against c. nucum, the growth rate, sporulation, and cumulative mortality of different metarhizium anisopliae and beauveria bassiana strains were investigated, and the process by which m. anisopliae com 02 infects c. nucum larvae was observed using scanning electron microscopy. the results indicated that the growth rate and ... | 2016 | 27784935 |
| infectivity of steinernema carpocapsae and s. feltiae to larvae and adults of the hazelnut weevil, curculio nucum: differential virulence and entry routes. | we investigated the existing susceptibility differences of the hazelnut weevil, curculio nucum l. (coleoptera:, curculionidae) to entomopathogenic nematodes by assessing the main route of entry of the nematodes, steinernema carpocapsae strain b14 and s. feltiae strain d114, into larvae and adult insects, as well as host immune response. our results suggested that s. carpocapsae b14 and s. feltiae d114 primarily entered adult insects and larvae through the anus. larvae were more susceptible to s. ... | 2014 | 25276002 |
