Indagini di base per l'impiego diEntomophaga maimaiganel controllo diLymantria disparin ambiente mediterraneo
Full text linkLymantria disparlarvae were collected in 20 oak stands in Sardinia to evaluate mortality factors. Collected larvae were reared in the laboratory on artificial diet until they died or pupated. Larval mortality ranged from 17,5% to 100%. Parasitoids that killed larvae were identified and the remaining larvae were evaluated for presence of pathogens. The tachinidBlepharipa pratensiswas the most frequently observed and caused up to 57% mortality. The viral pathogen LdNPV caused mortality up to 37,5%. We recorded the presence ofBeauveria bassianaas well as the microsporidiumNosema portugal, which was previously identified as Nosema lymantriae. The fungal entomopathogenEntomophaga maimaigawas not collected from the host populations surveyed. This fungus is a virulent and very host specific pathogen of the gypsy moth. We started bioassays to verify the effectiveness against gypsy moth larvae from Sardinia and other parts of Italy. Two methodologies were followed: larvae were exposed to contaminated soil containingE. maimaigaazygospores; larvae were sunk in a water suspension containing the fungus azygospores. Mortality caused by fungus was 4,16% in 2012, 3% in 2013 and 2,06% in 2014 for the first method and 4.70% for the second method. In order to exclude negative effects for the environment and lay the foundations for the introduction ofE. maimaigain Sardinia we verified the action of the fungus against other lepidopteran larvae: none of them were killed by the fungus
